Víctor Gonzal's questions

Hi, I'm trying to make it so that when you touch a map in one of my views, the map occupies the entire screen and with another touch it shrinks to its original size without it disappearing.

This is the structure of my views:

And when executing the following code:

 override func viewDidLoad() {
    super.viewDidLoad()

    let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(VistaDetalleNivelUnoVC.ModifySize))
    mapLocation.addGestureRecognizer(tap)
}

func dismissFullscreenImage(sender: UITapGestureRecognizer) {
    sender.view?.removeFromSuperview()
}

func ModifySize () {
    print("Full")
    let screenSize: CGRect = UIScreen.mainScreen().bounds
    let screenWidth = screenSize.width
    let screenHeight = screenSize.height
    mapLocation.userInteractionEnabled = true
    mapLocation.multipleTouchEnabled = true
    mapLocation.frame = CGRect(x: 0, y: 0, width: screenWidth, height: screenHeight)
    self.view.bringSubviewToFront(mapLocation)
    print(mapLocation.frame)

    let tap = UITapGestureRecognizer(target: self, action: #selector(VistaDetalleNivelUnoVC.dismissFullscreenImage(_:)))
    mapLocation.addGestureRecognizer(tap)
}

When you click on the map it looks like this:

and when I tap on it again it disappears completely:

How can I make the map occupy the whole screen in front of the other view that contains the UIImageView and how can I return it to its original size with a single touch.

I'm trying to put a Circular UIImageview into a UITableViewCell and I'm not having much success :(.

In my TableViewCell class

class ComentariosTVCell: UITableViewCell {


@IBOutlet weak var photoUser: UIImageView!

//weak var photoUser: UIImageView!

override func layoutSubviews() {


   
    photoUser.round()
    
    /*
     photoUser.layer.borderWidth = 1
     photoUser.layer.masksToBounds = true
     photoUser.layer.borderColor = UIColor.blackColor().CGColor
    
     photoUser.layer.cornerRadius = 40.0 //photoUser.bounds.height/2
    print("frame: ", photoUser.frame)
     photoUser.clipsToBounds = true*/
}


override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}}


public extension UIView {
public func round() {
    let width = bounds.width < bounds.height ? bounds.width : bounds.height
    let mask = CAShapeLayer()
    mask.path = UIBezierPath(ovalInRect: CGRectMake(bounds.midX - width / 2, bounds.midY - width / 2, width, width)).CGPath
    self.layer.mask = mask
}}

and when loading the table the view does not load correctly if not until one of the cells is selected or scrool is done.

where am I failing?

I am working with TableViewControllers and in my first TableView I have decided that an image will appear that occupies the entire length and width of the screen in such a way that what is behind it is not visible until the image disappears (This part is already achieved). I am doing it as follows:

   override func viewDidLoad() {
    super.viewDidLoad()
    let nav = self.navigationController?.navigationBar
    nav!.hidden = true
    let bounds = UIScreen.mainScreen().bounds
    let screenHeight = bounds.size.height
    let screenWidth = bounds.size.width
   

    let dynamicImage=UIImageView(frame: CGRectMake(0, 0, screenWidth, screenHeight))
    dynamicImage.backgroundColor=UIColor.greenColor()
    
    self.view.addSubview(dynamicImage)
  UIView.animateWithDuration(0.2, delay: 10.0, options: [] , animations: {() -> Void in
        dynamicImage.alpha = 0.0
        }, completion: {(true) -> Void in
            dynamicImage.removeFromSuperview()
            nav!.hidden = false
    })

The case is that the screen looks like this:

and it does not occupy the entire height of the screen, since the upper bar is still visible, in addition to the fact that if I touch the screen and slide upwards, the scroll scrolls through the UIImageview upwards. What I want is that the UIImageview contains an advertising image that lasts x number of seconds with the screen locked, however I have two problems:

1. Doesn't take up the whole screen
2. The UIImageview can be manipulated (i.e. scroll down as the scrollview scrolls.

Thank you

I have the following detail.

I have a series of TableViews, in whose cells I am loading background images, like so:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {



    let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! MenuSecundarioTVCell
    let seccion = items[indexPath.row]


        cell.titulo?.text = (seccion.value["nombre"] as! String)
        //PONIENDO IMAGEN DE FONDO A CELDA
        let imageBackground = UIImageView(frame: CGRectMake(0, 0, cell.frame.width , cell.frame.height+1))
        if let imageRemote = seccion.value["imageBackground"]{
            imageRemoteURL = NSURL(string: imageRemote as! String)
            imageBackground.sd_setImageWithURL(imageRemoteURL!)
            cell.backgroundView = UIView()
            cell.backgroundView!.addSubview(imageBackground)
        }
        //TERMINANDO DE PONER IMAGEN DE FONDO A CELDA

    return cell
}

I am using SDWebImage . The problem is that when the images are loaded into the cells they look like this:

After performing another action such as sliding the cells down or selecting the cell to go to the next view, when returning the image is rearranged in the correct way:

the images are test and it is clear that the resolution of the images does not match the height of the cells (120)

 override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return 120
    }

Will the origin of the problem be that the resolution of the images must match the size of the cells? I have seen this problem in some apps published in the appstore but the rearrangement is so fast that it is almost unnoticeable.

I have my views(UITableViewController) and from the storyBoard I have embedded these views in a NavigationController. The thing is that I am wanting to modify the size of the NavigationBar that comes inside the UINavigationController, specifically I am wanting to modify the height.

I am handling the following code inside the ViewDidAppear to make the modification.

//TESTING NAVIGATIONBAR CUSTOM
    let bounds = UIScreen.mainScreen().bounds
    //let screenHeight = bounds.height



    let nav = self.navigationController?.navigationBar


    nav?.barStyle = UIBarStyle.Black
    nav?.tintColor = UIColor.yellowColor()
    // nav?.frame = CGRectMake(0, 0, bounds.size.width, 60)
    nav?.frame=CGRectMake(0, 0, bounds.size.width, 80)

    //END NAVIGATIONBAR CUSTOM

And the modification part works, the problem comes when I run the app and an empty strip appears between the navigationBar and the first cell of the UITableViewController.

How can I avoid the fringe?

I am trying to use FirebaseLoginViewControllerto be able to authenticate my users. At the moment the code is like this:

import UIKit

class AccesoPrincipal : FirebaseLoginViewController{


var loginViewController : FirebaseLoginViewController?
var loginButton : FirebaseLoginButton?
var logoutButton : FirebaseLoginButton?

override func viewDidLoad() {
    super.viewDidLoad()

    let firebaseRef = Firebase(url: "https://superapp.firebaseio.com/")

    self.loginViewController = FirebaseLoginViewController(ref: firebaseRef)
    self.loginViewController!.enableProvider(FAuthProvider.Facebook)
    //self.loginViewController.enableProvider(FAuthProvider.Google)
    //self.loginViewController.enableProvider(FAuthProvider.Twitter)
    self.loginViewController!.enableProvider(FAuthProvider.Password)


    // Scenario 2: Set up user action based login flow
    loginButton!.addTarget(self, action: "login", forControlEvents: UIControlEvents.TouchUpInside)
    logoutButton!.addTarget(self, action: "logout", forControlEvents: UIControlEvents.TouchUpInside)
}


// Scenario 2: User action launches login flow, dismissal and routing handled by `FirebaseLoginViewController`
func login() {
    if ((self.loginViewController!.currentUser() == nil)) {
        self.presentViewController(self.loginViewController!, animated: true, completion: nil)
    }
}

override func logout() {
    if ((self.loginViewController!.currentUser()) != nil) {
        self.loginViewController!.logout()
        }
    }
}

When I run the application I get the following error code:

I understand that the error is because an authentication provider has not been detected, however, that part is defined within the viewController, isn't it? There isn't much documentation FirebaseUIso it's been hard to find anything about it.

After the announcement that it stops, it closes in January of next year. I have decided to use Firebase. The good news is that my App is still in development and hadn't made much progress, however one of the parts that had already been tested was authentication. I used PFLogInViewController at the time to make my life easier but now with firebase I'm trying to use FirebaseLoginViewController which works in a very similar way, both classes (FirebaseLoginViewController and PFLogInViewController ) inherit from UIViewController and at least in parse it was very easy to customize. In firebase there is not much documentation about it and I am giving up.

This is what I have at the moment.

import UIKit
class AccesoPrincipal : FirebaseLoginViewController{



override func viewDidLoad() {
    super.viewDidLoad()

    let firebaseRef = Firebase(url: "https://superaapp.firebaseio.com/")

    self.loginViewController = FirebaseLoginViewController(ref: firebaseRef)
    self.loginViewController.enableProvider(FAuthProvider.Facebook)
    //self.loginViewController.enableProvider(FAuthProvider.Google)
    //self.loginViewController.enableProvider(FAuthProvider.Twitter)
    self.loginViewController.enableProvider(FAuthProvider.Password)
    // Scenario 1: Set up captive portal login flow
    self.loginViewController.didDismissWithBlock { (user: FAuthData, error: NSError) -> Void in
        if (user) {
            // Handle user case
        } else if (error) {
            // Handle error case
        } else {
            // Handle cancel case
        }
    }



// Scenario 1: Application launches login flow, handles dismissal and routing in `didDismissWithBlock:`
override func viewDidAppear(animated: Bool) {
    if (!self.loginViewController.currentUser()) {
        self.presentViewController(self.loginViewcontroller, animated: true, completion: nil)
    }
}



override func logout() {
    if (self.loginViewController.currentUser()) {
        self.loginViewController.logout()
    }
}

}

The above code snippet was taken from the FirebaseUi-IOS documentation itself [ https://github.com/firebase/FirebaseUI-iOS] and I've been running into errors.

My pod install file

   platform :ios, '9.2'

pod 'Firebase'
pod 'FirebaseUI', '~> 0.3'

my header.h file, where I don't know if I'm correctly calling FirebaseLoginViewController

    #ifndef Header_h
#define Header_h


#endif /* Header_h */
#import <FirebaseLoginViewController.h>
#import <Firebase/Firebase.h>

I have created several classes in parse and many of them are related to each other by Pointers. An example is the following.

I have 2 classes:

• subcategorias
• comercios

In comerciosI can have records from many businesses, there is a field called come_subc_idand it is linked to the class subcategoriasby means of a Pointer.

In the class subcategoriasI have a classification of all businesses, that is, if it is a hotel, a restaurant, a laundry, etc.

I have one PFQueryTableViewControllerwhere I intend to show a list of, for example, all the hotels.

If in my class subcategorias, for example objectId, the hotels class is gL8qGBhXMI, how can I generate the query so that it only shows me in the table all the hotels that I have registered in the business class? My question is, how can I generate a query of a class by accessing the fields of another class through the pointer? I am trying as follows, but with errors and I have the following code and I still can't refine it and I don't know if I'm going in the right direction.

override func queryForTable() -> PFQuery {
let queryHot = PFQuery(className: "comercios") //El que funciona
        queryHot.includeKey("come_subc_id") //Tipo pointer apuntando a clase subcategorias
        queryHot.whereKey("come_subc_id", equalTo: "gL8qGBhXMI") // comparando si el registro tiene clasificacion de hotel
return queryHot
}

When I run the application, I get the following error:

2016-01-24 14:05:35.579 AppBeta1[1045:35017] [Error]: pointer field come_subc_id needs a pointer value (Code: 102, Version: 1.11.0)

I understand that the error is thrown in the query when I do the comparison:

queryHot.whereKey("come_subc_id", equalTo: "gL8qGBhXMI")

Since the field come_subc_idis not of type stringbut rather an object, my question is about how to implement the correct method to perform this comparison. If I manage to understand this part, I will be able to practically perform all the queries that are generated in my application since all the classes are related by pointers.

If I have not been completely clear, I can restate my problem.

Thank you for your support.

I have been following a tutorial on how to implement a login with parse with the function of logging in with Facebook and Twitter, however, I find a detail.

In principle, the elements of the main view are hidden by means of the function viewDidLayoutSubviews, that is, they are sent to the bottom of the screen and then move up in the form of animation, this animation is executed in the function viewDidAppear.

So far everything is perfect, however when I select one of those textFieldsthat are part of the view to enter a text, obviously the keyboard appears and in theory I should move the elements up so as not to hide them when writing, here I suppose that it is activates the function again viewDidLayoutSubviewsand executes the code snippet that hides me all the elements at the bottom as it is done when the application loads to make the animation possible.

How can I prevent the elements from disappearing every time I try to write to any of the textFields?

override func viewDidLoad() {
        super.viewDidLoad()

 // create an array of all the views we want to animate in when we launch the screen

        viewsToAnimate = [self.logInView?.usernameField, self.logInView?.passwordField, self.logInView?.logInButton, self.logInView?.passwordForgottenButton, self.logInView?.facebookButton, self.logInView?.signUpButton, self.logInView?.logo]
}

override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()


        // We to position all the views off the bottom of the screen
        // and then make them rise back to where they should be
        // so we track their final position in an array
        // but change their frame so they are shifted downwards off the screen


        viewsFinalYPosition = [CGFloat]();
        for viewToAnimate in viewsToAnimate {
            //print(viewToAnimate.frame)
            let currentFrame = viewToAnimate.frame
            print(viewsFinalYPosition.count)
            viewsFinalYPosition.append(currentFrame.origin.y)
            viewToAnimate.frame = CGRectMake(currentFrame.origin.x, self.view.frame.height + currentFrame.origin.y, currentFrame.width, currentFrame.height)
        }
    }

override func viewDidAppear(animated: Bool) {


        super.viewDidAppear(animated)


        // Now we'll animate all our views back into view
        // and, using the final position we stored, we'll
        // reset them to where they should be
        if viewsFinalYPosition.count == self.viewsToAnimate.count {
            UIView.animateWithDuration(1, delay: 0.0, options: .CurveEaseInOut,  animations: { () -> Void in
                for viewToAnimate in self.viewsToAnimate {
                    print(viewToAnimate.frame)
                    let currentFrame = viewToAnimate.frame
                     print(self.viewsFinalYPosition.count)
                    viewToAnimate.frame = CGRectMake(currentFrame.origin.x, self.viewsFinalYPosition.removeAtIndex(0), currentFrame.width, currentFrame.height)
                }
                }, completion: nil)
        }
    }
