1、创建类别文件Create.h/m

//.h#import <UIKit/UIKit.h>@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;@end//.m#import "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* newPressdImage = [UIImage imageNamed:imagePressed];    [button setBackgroundImage:newPressdImage 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;}/*// Only override drawRect: if you perform custom drawing.// An empty implementation adversely affects performance during animation.- (void)drawRect:(CGRect)rect {    // Drawing code}*/@end

2、使用

包含上面创建的头文件

@implementation NBViewController- (void)viewDidLoad {    [super viewDidLoad];    [self.view addSubview:[UIButton createButtonWithFrame:CGRectMake(0, 0, 160, 280) Title:@"测试" Target:self Selector:@selector(buttonPressed:)]];    [self.view addSubview:[UIButton createButtonWithFrame:CGRectMake(0, 0, 160, 40) Target:self Selector:@selector(buttonPressed:) Image:@"img0" ImagePressed:@"img2"]];}-(void)buttonPressed:(id)sender{    NSLog(@"点我");}
