问题 I have been looking for any example code for drawing a UILabel (or just an NSString or something) on a curved path, but have come up empty handed. Does anyone know whether it's possible to draw text on a curved path, like a circle or something, without using separate pieces of graphics for every single letter? 回答1: Split the String into letters and then so something like this: How do I draw an NSString at an angle? increasing the angle and changing the position after every letter. 来源： https:/

问题 I work for a media company, and in our iPad application we're upgrading our content so it looks better. Previously, we used a UILabel to display the contents of our posts. I used this to get the actual height of my UILabel: CGSize expectedSize = [label.text sizeWithFont:label.font constrainedToSize:maximumLabelSize lineBreakMode:label.lineBreakMode]; However, we changed our posts' content to HTML, so I'm using a UIWebView. Is there a way to find the true height of the UIWebView, like I do

问题 I have two UILabel in a custom tableViewCell . One label has width constraints and is set to adjustFontSizeToFitWidth on smaller screens e.g. 5S.

It seems sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode: was deprecated in iOS7, so what is the Swift solution? This answer When do adjustsFontSizeToFitWidth or boundingRectWithSize change the context

问题 Setting lineBreakMode to byWordWrapping and set numberOfLines to 0 does not seem to be sufficient: struct MyTextView: UIViewRepresentable { func makeUIView(context: Context) -> UILabel { let label = UILabel() label.lineBreakMode = .byWordWrapping label.numberOfLines = 0 label.text = "Here's a lot of text for you to display. It won't fit on the screen." return label } func updateUIView(_ view: UILabel, context: Context) { } } struct MyTextView_Previews: PreviewProvider { static var previews:
