我正在尝试在没有运气的情况下为按钮标签添加1px黑色阴影。我试过这个:self.setTitleShadowOffset = CGSizeMake(0, -1);
但是我得到了:
在非结构或联合的内容中请求成员'setTitleShadowOffset'
任何建议都会非常棒,谢谢!

正确的属性是self.titleLabel.shadowOffset:
UIButton *b = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[b setTitleShadowColor:[UIColor purpleColor] forState:UIControlStateNormal];
b.titleLabel.shadowOffset = CGSizeMake(1.0, 1.0);
[b setTitle:@"Hello, I'm a Button" forState:UIControlStateNormal];
b.frame = CGRectMake(10.0, 10.0,300.0, 40.0);

其他答案没有正确设置阴影颜色(我怀疑他们没有注意到,因为他们试图将阴影颜色设置为默认颜色,黑色。)
此代码可以让我在按钮文本中添加白色阴影:
myButton.titleLabel.shadowOffset = CGSizeMake(0, 1);
[myButton setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateNormal];

在Swift 3.0中
myButton.titleLabel?.layer.shadowRadius = 3
myButton.titleLabel?.layer.shadowColor = UIColor.black.cgColor
myButton.titleLabel?.layer.shadowOffset = CGSize(width: 0, height: 1)
myButton.titleLabel?.layer.shadowOpacity = 0.5
myButton.titleLabel?.layer.masksToBounds = false

对于Swift 3:
button.setTitleShadowColor(UIColor.red, for: .normal)
button.titleLabel?.shadowOffset = CGSize(width: 2, height: 2)

以下是如何使用radius属性在Objective-C中的按钮标题中添加阴影:
#import <QuartzCore/QuartzCore.h>
button.titleLabel.layer.shadowOffset = CGSizeMake(2.0, 2.0);
button.titleLabel.layer.shadowColor = [UIColor colorWithWhite:0.1 alpha:0.7].CGColor;
button.titleLabel.layer.shadowRadius = 2.0;
button.titleLabel.layer.shadowOpacity = 1.0;
button.titleLabel.layer.masksToBounds = NO;
