iOS －实现UIView圆角显示的方法

添加一个UIView时，默认直角显示有时对于有强迫症的患者还真有点不舒服！

eg：

怎么实现UIview的圆角显示呢？

首先包含一个头文件：

#import <QuartzCore/QuartzCore.h>

其次设置两个属性：

    self.userView.layer.cornerRadius = 2;
    self.userView.layer.masksToBounds = YES;

eg：

-(void)setupUI {
    //set subview round corners
    self.userView.layer.cornerRadius = 2;
    self.userView.layer.masksToBounds = YES;
    //set backgroundColor
    [self.userView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"textField_normal"]]];
    self.userNameButton.enabled = NO;

    self.passwordView.layer.cornerRadius = 2;
    self.passwordView.layer.masksToBounds = YES;
    [self.passwordView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"textField_normal"]]];
    self.passwordButton.enabled = NO;

}
