iOS －實現UIView圓角顯示的方法

添加一個UIView時，默認直角顯示有時對於有強迫症的患者還真有點不舒服！

eg：

怎麼實現UIview的圓角顯示呢？

首先包含一個頭文件：

#import <QuartzCore/QuartzCore.h>

其次設置兩個屬性：

    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;
    
}
