IOS设置UIView的边框和圆角

iOS 系统自带的 View 组件都是正方形的，看起来都太生硬，有时候我需要加边框变成圆角形式，代码实现：

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 80, 80)];
    view.layer.cornerRadius = 10;
    view.layer.masksToBounds = YES;
    view.layer.borderWidth = 1;

    view.layer.borderColor = [[UIColor colorWithRed:0.52 green:0.09 blue:0.07 alpha:1] CGColor];
