我有一个方法创建一个自定义UIButton,允许我使用QuartzCore更改按钮的颜色.但触摸时按钮不会突出显示.
- (UIButton *)makeHeaderButton { UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; UIFont *textFont = [UIFont boldSystemFontOfSize:12]; UIColor *textColor = [UIColor colorWithRed:80/255.0 green:109/255.0 blue:145/255.0 alpha:1.0]; UIColor *backgroundColor = [UIColor colorWithRed:250/255.0 green:250/255.0 blue:250/255.0 alpha:1.0]; [button setTitleColor:textColor forState:UIControlStateNormal]; button.titleLabel.font = textFont; button.autoresizesSubviews = YES; button.layer.cornerRadius = 8; button.layer.borderWidth = 1; // next 2 properties set using QuartzCore class,no other way to set button colors button.layer.borderColor = [UIColor grayColor].CGColor; button.layer.backgroundColor = backgroundColor.CGColor; button.clipsToBounds = YES; return button; }
如何使这些按钮像常规的圆形按钮一样突出显示?
