这里有一个:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

UIButton *saveLibrary=[UIButton buttonWithType:UIButtonTypeCustom];

[saveLibrary setTitle:@"Library" forState:UIControlStateNormal];

[saveLibrary setBackgroundColor:[UIColor redColor]];

[saveLibrary addTarget:self 
action:@selector(saveOnGalleryButtonIsPressed) forControlEvents:UIControlEventTouchUpInside];

[saveLibrary setImage:[UIImage imageWithContentsOfFile:[[[NSBundle mainBundle] bundlePath] stringByAppendingString:@"/library225.png"]]forState:UIControlStateNormal];

saveLibrary.frame=CGRectMake(323, 15, 75, 75);  

[self.view addSubview:saveLibrary];

试一试……

UIButton *finalPriceBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
finalPriceBtn.frame=CGRectMake(260, 25, 45, 15);
[finalPriceBtn addTarget:self action:@selector(goBtnClk:) forControlEvents:UIControlEventTouchUpInside];
finalPriceBtn.titleLabel.font=[UIFont systemFontOfSize:12];
[finalPriceBtn setTitle:[NSString stringWithFormat:@"$%.2f",tempVal] forState:UIControlStateNormal];
finalPriceBtn.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f  alpha:1];
finalPriceBtn.titleLabel.textAlignment=UITextAlignmentLeft;
[imageView addSubview:finalPriceBtn];

希望我能帮上忙。

如果愿意，可以将创建者实例放入循环中，并从数组中动态添加名称。

这里有一个:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

你可以通过这段代码创建按钮。

 UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
 [btn addTarget:self action:@selector(btnAction) forControlEvents:UIControlEventTouchDragInside];
 [btn setTitle:@"click button" forState:UIControlStateNormal];
  btn.frame = CGRectMake(50, 100, 80, 40);
  [self.view addSubview:btn];

下面是按钮动作方法

 -(void)btnAction
 {
   NSLog(@"button clicked");
 }
