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");
}
