UIButton *btnAdd = [[UIButton alloc] init];

[btnAdd setBackgroundImage:[UIImage imageNamed:@"019.png"] forState:UIControlStateNormal];

btnAdd.frame = CGRectMake(x,y, WIDTH_HIGHT, WIDTH_HIGHT);//

[self.view addSubview:btnAdd];

定义一个函数，如何将这个函数作为单击按钮的响应事件？

好得，知道了，谢谢了额

1. [btnAdd addTarget:self action:@selector(自定义方法名) forControlEvents:UIControlEventTouchUpInside];
