如何在UISegmentControl中更改文本颜色？

Question

谁能建议我如何更改UISegment控件的文本颜色？

Answer 1

The Apple Documentation does not specify a method for doing this programatically. The easiest way to do this would be to take a screen shot of each of the segmented control segments without text on them. Then open up photoshop or gimp and add the desired text with whatever coloring you would like. Then tell the slider to you your images like so (Assumes 2 Segments):

UIImage *segmentOne = [[UIImage imageNamed:@"segmentOne.png"] stretchableImageWithLeftCapWidth:4 topCapHeight:0];
UIImage *segmentTwo = [[UIImage imageNamed:@"segmentTwo.png"] stretchableImageWithLeftCapWidth:4 topCapHeight:0];
[_segmentedControl setImage:segmentOne forSegmentAtIndex:0];
[_segmentedControl setImage:segmentTwo forSegmentAtIndex:1];

I realize this is an old question, but it was the first relevant hit on this.

The modern way, from UICatalog , is:

NSDictionary *textAttributes = @{ UITextAttributeTextColor:[UIColor blueColor],
                                  UITextAttributeFont:[UIFont systemFontOfSize:13.0] };
[segmentedControl setTitleTextAttributes:textAttributes
                                forState:UIControlStateNormal];

textAttributes = @{ UITextAttributeTextColor:[UIColor redColor],
                    UITextAttributeFont:[UIFont systemFontOfSize:13.0] };
[segmentedControl setTitleTextAttributes:textAttributes
                                forState:UIControlStateHighlighted];

setTitleTextAttributes:forState: first appeared in iOS 5, so there's no reason not to use it these days.

Worth mentioning: You'll probably want to set UITextAttributeTextShadowColor , too.
