If I set textLayer.wrapped = YES
, how do I resize textLayer
to contain the wrapped text? I.e., how do I get the new height of the textLayer
?
Basically, I want something like -[UILabel sizeToFit]
.
The first thing you need to do is get the size of the text.
Thankfully, the NSString UIKit Additions Reference offers a method to do exactly that:
- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(UILineBreakMode)lineBreakMode
That will give you a CGSize
that you can then use to set the frame of your UILabel
or whatever subclass of UIView
that you're using.
So, assuming textLayer
is a UILabel
- rather than a CALayer
- you'll end up with something like this:
UIFont *myFont = [UIFont boldSystemFontOfSize:12.0f];
CGSize myFontSize = [myString sizeWithFont:myFont];
myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, myFontSize.width, myFontSize.height)];
myLabel.text = newTitle;
myLabel.font = myFont;
