[iOS 13] Support for UISegmentedControl setTitleTextAttributes

[n3d1117]

Hello, could you add support for the new method setTitleTextAttributes:for: that was added in UISegmentedControl with iOS 13? Thanks

[wxxsw]

No problem, I will support this weekend.

Example:

segmentedControl.theme_setTitleTextAttributes([
    [.foregroundColor: UIColor.purple],
    [.foregroundColor: UIColor.blue],
], forState: .normal)

Thank you! However my app crashes when I use it. Any idea why?

Here's the crash log:

It seems that the wrong attributes dictionary parameter type is used. Can you show me your code?

[n3d1117]

I'm using it like this:

segment = UISegmentedControl(items: ...)
segment.theme_tintColor = ...
segment.theme_setTitleTextAttributes([ [.foregroundColor: UIColor.purple] ], forState: .normal)
contentView.addSubview(segment)

If I use the original method everything works fine:

segment.setTitleTextAttributes([AttributedStringKey.foregroundColor: UIColor.red], for: .normal)

Not sure what's going on. I can't seem to reproduce the crash on a sample project. I will look further into it
