自定义UIButton

先建一个页面继承自UIButton

//.h文件

#import <UIKit/UIKit.h>

@interface MyButton : UIButton

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

@end

//.m文件

#import "MyButton.h"

@implementation MyButton

+ (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;

}
