@implementationUIButton (Create)

  

+ (UIButton*) createButtonWithFrame: (CGRect) frame Target:(id)targetSelector:(SEL)selectorImage:(NSString*)image ImagePressed:(NSString*)imagePressed

{

    UIButton* button = [UIButtonbuttonWithType:UIButtonTypeCustom];

    [buttonsetFrame:frame];

    UIImage*newImage = [UIImageimageNamed:image];

    [buttonsetBackgroundImage:newImageforState:UIControlStateNormal];

    UIImage*newPressedImage = [UIImageimageNamed:imagePressed];

    [buttonsetBackgroundImage:newPressedImageforState:UIControlStateHighlighted];

    [buttonaddTarget:targetaction:selectorforControlEvents:UIControlEventTouchUpInside];

    returnbutton;

}

  

+ (UIButton*) createButtonWithFrame:(CGRect)frameTitle:(NSString*)title Target:(id)targetSelector:(SEL)selector

{

    UIButton* button = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

    [buttonsetFrame:frame];

    [buttonsetTitle:titleforState:UIControlStateNormal];

    [buttonaddTarget:targetaction:selectorforControlEvents:UIControlEventTouchUpInside];

    returnbutton;

}

  

@end

  

使用方法，首先在要使用的ViewController

包含#import "UIButton+Create.h"

然后使用方法

  

- (void)viewDidLoad

{

    [superviewDidLoad];

    [self.viewaddSubview:[UIButtoncreateButtonWithFrame:CGRectMake(0,0,160,40)Title:@"测试"Target:selfSelector:@selector(buttonPressed:)]];

    [self.viewaddSubview:[UIButtoncreateButtonWithFrame:CGRectMake(0,100,160,40)Target:selfSelector:@selector(buttonPressed:)Image:@"这个是你给这个Button设置的默认图片"ImagePressed:@"button点击后显示的高亮的图片"]];

}

  

- (void)buttonPressed:(id)sender

{

  

}
