	@interface UIButton (Create)
	+ (UIButton*) createButtonWithFrame: (CGRect) frame Target:(id)target Selector:(SEL)selector Image:(NSString *)image ImagePressed:(NSString *)imagePressed;
	+ (UIButton *) createButtonWithFrame:(CGRect)frame Title:(NSString *)title Target:(id)target Selector:(SEL)selector;

	#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
	{
	
	}
