本文介绍了一个用于UIButton的自定义扩展方法，该方法允许开发者通过一行代码创建带有指定标题、大小、点击事件及背景图片的按钮。这极大简化了UIButton的初始化过程。

+ (UIButton *)buttonWithTitle:(NSString *)title frame:(CGRect) frame target:(id)target action:(SEL)action backgroundImage:(NSString *)backgroundImage selectedImage:(NSString *)selectedImage;

使用扩展

#import "UIButton+Extension.h"
@implementation UIButton (Extension)

+ (UIButton *)buttonWithTitle:(NSString *)title frame:(CGRect) frame target:(id)target action:(SEL)action backgroundImage:(NSString *)backgroundImage selectedImage:(NSString *)selectedImage {
    //  创建一个按钮
    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
    //   设置按钮背景颜色
//    button.backgroundColor = [UIColor colorWithRed:0.601 green:0.596 blue:0.906 alpha:1.000];
    //  设置按钮大小
    button.frame = frame;
    //    设置背景图片
    [button setBackgroundImage:[UIImage imageNamed:backgroundImage] forState:UIControlStateNormal];
    //   设置背景选择图片
    [button setBackgroundImage:[UIImage imageNamed:selectedImage] forState:UIControlStateHighlighted];
    //   设置按钮的标题
    [button setTitle:title forState:UIControlStateNormal];
    //   设置按钮的点击事件
    [button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
    return button;
}
