#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 , 1 6 0 , 4 0 ) Title : @"测试" Target : self Selector : @selector (buttonPressed:)]];
    [ self .view addSubview :[ UIButton createButtonWithFrame :CGRectMake( 0 , 1 0 0 , 1 6 0 , 4 0 ) 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
{

}
