UIButton

UIButton相关代码如下：

        UIButton *fistBt = [[UIButton alloc] initWithFrame:CGRectMake(10, 130, SCREEN_WIDTH/2 - 25, 40)];
        [fistBt.layer setCornerRadius:5];
        [fistBt setTitle:@"取消" forState:0];
        [fistBt setTintColor:RGB(255, 106, 34)];
        [fistBt setBackgroundColor:[UIColor lightGrayColor]];
        [fistBt addTarget:self action:@selector(fistClick) forControlEvents:UIControlEventTouchUpInside];

给button添加图片

    //设置button填充图片,不会拉伸控件
    [button1 setImage:[UIImage imageNamed:@"btng.png"] forState:UIControlStateNormal];
