【iOS】UIButton 常用属性

发现 UIButton 的相关属性不熟悉了……常用的一些属性代码如下：

　　 UIButton *add = [UIButton buttonWithType:UIButtonTypeCustom];
    add.frame = CGRectMake(WIDTH-, , , );
    add.layer.masksToBounds = YES;
    add.layer.cornerRadius = 8.0;
    add.layer.borderWidth = 1.0; //边框宽度
    add.backgroundColor = [UIColor whiteColor];
//    add.titleLabel.backgroundColor = [UIColor blueColor];

    [add setTitle:@"Add" forState:UIControlStateNormal];
    [add setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
    [self.view addSubview:add];
    [add addTarget:self action:@selector(addSth) forControlEvents:UIControlEventTouchUpInside];

效果如图所示：
