Foundation MonoTouchException NSInternalInconsistencyException SearchBar

  • 772

I have a mobile app in Xamarin Forms 3.2, which works fine on Android, however when I run the build for iOS, it compiles without errors, loads the iOS emulator, and throws the following exception:

Objective-C exception thrown.  Name: NSInternalInconsistencyException Reason: -[UISearchBar sizeThatFits:] does not support passing non-finite values ({inf, 56})

Within the properties, I have the following:

Foundation MonoTouchException NSInternalInconsistencyException

-[UISearchBar sizeThatFits:] does not support passing non-finite values ​​({inf, 56})

It strikes me that it works well on Android and that it breaks on iOS; Anyway, effects of the learning curve, by the way, this is the XAML that I am using:

<SearchBar Grid.Row="0" Margin="0,20,0,0" Placeholder="Search" SearchCommand="{Binding Path=SearchingCommand}" Text="{Binding Path=SearchQuery}"></SearchBar>

    The only thing missing was adding the WidthRequest property

    <SearchBar Grid.Row="0" Margin="0,20,0,0" Placeholder="Search" SearchCommand="{Binding Path=SearchingCommand}" Text="{Binding Path=SearchQuery}" WidthRequest="50"></SearchBar>

    Now it works perfectly!

    According to the documentation:

    https://docs.microsoft.com/en-us/dotnet/api/xamarin.forms.searchbar?view=xamarin-forms

    The WidthRequest property

    IN:

    Gets or sets the desired width override of this element.

    IT IS:

    Gets or sets the desired width of this element.
