#import "UIButton+Create.h"

  

@implementation UIButton (Create)

  

+ (UIButton*) createButtonWithFrame: (CGRect) frame Target:(id)target Selector:(SEL)selector Image:(NSString *)image ImagePressed:(NSString *)imagePressed

{

    UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];

    [button setFrame:frame];

    UIImage *newImage = [UIImage imageNamed: image];

    [button setBackgroundImage:newImage forState:UIControlStateNormal];

    UIImage *newPressedImage = [UIImage imageNamed: imagePressed];

    [button setBackgroundImage:newPressedImage forState:UIControlStateHighlighted];

    [button addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside];

    return button;

}

  

+ (UIButton *) createButtonWithFrame:(CGRect)frame Title:(NSString *)title Target:(id)target Selector:(SEL)selector

{

    UIButton * button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    [button setFrame:frame];

    [button setTitle:title forState:UIControlStateNormal];

    [button addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside];

    return button;

}

  

@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

{

    [super viewDidLoad];

    [self.view addSubview:[UIButton createButtonWithFrame:CGRectMake(0, 0, 160, 40) Title:@"测试" Target:self Selector:@selector(buttonPressed:)]];

    [self.view addSubview:[UIButton createButtonWithFrame:CGRectMake(0, 100, 160, 40) Target:self Selector:@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

{

  

}
