尝试这段代码来创建一个按钮，并使用不同的坐标重复它2次，当按钮被按下时，方法(myButtonClick)被调用

UIButton *editButton = [UIButton buttonWithType: UIButtonTypeCustom];
editButton.frame = CGRectMake(0, 0, width, height);
[editButton setBackgroundImage: editButtonImage forState: UIControlStateNormal];
[myButton addTarget:self action:@selector(myButtonClick:)    forControlEvents:UIControlEventTouchUpInside]; 
editButton.adjustsImageWhenHighlighted = YES;
editButton.titleLabel.text = @"Edit";
editButton.titleLabel.textColor = [UIColor whiteColor];
editButton.titleLabel.textAlignment = UITextAlignmentCenter;
editButton.titleLabel.font = [UIFont fontWithName: @"Helvetica" size: 14];
[self.view addSubview: editButton];

-(void) myButtonClick:(NSString *)myString{

   NSLog(@"you clicked on button %@", myString);
}

UIButton * tmpBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[tmpBtn addTarget:self action:@selector(clearCart:) forControlEvents:UIControlEventTouchUpInside];
tmpBtn.tag = k;
tmpBtn.frame = CGRectMake(45, 0, 15, 15);
[tmpBtn setBackgroundImage:[UIImage imageNamed:@"CloseButton.png"] forState:UIControlStateNormal];
[self.view addSubview:tmpBtn];

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。

UIButton *btnname = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[btnname setTitle:@"Click Me" forState:UIControlStateNormal];

btnname.frame = CGRectMake(10, 10, 100, 140);

[self.view addSubview:btnname];

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];

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。
