icons problem when set by code

[mabdollahiasl]

hi make an iconbutton and on click of it change the text with another icon it shows just '...' as icon. it happens just on ios.

I may find it.It could not be '...' but the word your set like 'fas-xxx-xxx'. with latest packages on iOS 12.2. I found UIButton.SetTitle() was called twice. One is by IconButtonRenderer and another is by ButtonLayoutManager. You can see there is no updatetext method in ButtonRenderer,and i fount it in ButtonLayoutManager.

	public ButtonRenderer()
		{
		......
			_buttonLayoutManager = new ButtonLayoutManager(this);
		}

and in 'ButtonLayoutManager',

	void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
		{
		......
			else if (e.PropertyName == Button.TextProperty.PropertyName)
				UpdateText();
		......
		}

You can override the UIButton.SetTitle then write stacktrace to view the call stack. I'm not sure if this is the true factor,and I'm finding a workaround ,my be I need rewrite the whole IconButtonRenderer?

I create a subclass of IconButton and add a new property 'IconProperty' and use it ,then rewrite the render to use 'IconPropery' ,seem work well.

I am having the same problem, sometimes it just shows e.g. "fas-download" on iOS. @meiotoha could you create a pull request and let them merge your fix?

I am having this same issue. Is there a fix on the way?

I have a lame fix where I pop the button out of the layout and then push it back in. It forces a layout. It is also hackyAF.
