推荐答案

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设置阴影颜色阴影颜色默认为黑色。）

The other answers do not properly set the shadow color (I suspect they didn't notice because they were trying to set the shadow color to what it is by default, black.)

此代码可以为我的按钮文本添加白色阴影：

myButton.titleLabel.shadowOffset = CGSizeMake(0, 1); [myButton setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateNormal];
