Is it possible to adjust x,y position for titleLabel of UIButton?

问题

Is it possible to adjust the x,y position for the titleLabel of a UIButton?

Here is my code:

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    [btn setFrame:CGRectMake(0.0f, 0.0f, 100.0f, 100.0f)];
    [btn setTitle:[NSString stringWithFormat:@"Button %d", i+1] forState:UIControlStateNormal];     
    [btn addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
    btn.titleLabel.frame = ???

回答1:

//make the buttons content appear in the top-left
[button setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];
[button setContentVerticalAlignment:UIControlContentVerticalAlignmentTop];

//move text 10 pixels down and right
[button setTitleEdgeInsets:UIEdgeInsetsMake(10.0f, 10.0f, 0.0f, 0.0f)];

And in Swift

//make the buttons content appear in the top-left
button.contentHorizontalAlignment = .Left
button.contentVerticalAlignment = .Top

//move text 10 pixels down and right
button.titleEdgeInsets = UIEdgeInsetsMake(10.0, 10.0, 0.0, 0.0)

The easiest way to do it visually is to use the attribute inspector** (appears when editing a xib/storyboard), setting the "edge" property to title, adjusting it's insets, then setting "edge" property to image, and adjusting accordingly. It's usually better than coding it , since it's easier to maintain and highly visual.

Derive from UIButton and implement the following method:

- (CGRect)titleRectForContentRect:(CGRect)contentRect;

Edit:

@interface PositionTitleButton : UIButton
@property (nonatomic) CGPoint titleOrigin;
@end

@implementation PositionTextButton
- (CGRect)titleRectForContentRect:(CGRect)contentRect {
  contentRect.origin = titleOrigin;
  return contentRect;
}
@end

For my projects I've this extension utility:

extension UIButton {

    func moveTitle(horizontal hOffset: CGFloat, vertical vOffset: CGFloat) {
        self.titleEdgeInsets.left += hOffset
        self.titleEdgeInsets.top += vOffset
    }

}
