xcode4.2 完成输入后关闭键盘

http://hongmin118.iteye.com/blog/1343383

viewController的接口中:

@interface ControlFunViewController : UIViewController {  
    UITextView *nameField;  
    UITextView *numberField;  
}  
  
@property (nonatomic, retain) IBOutlet UITextField *nameField; //我在这里写错了，写成了UITextView，搞了半天没搞对  
@property (nonatomic, retain) IBOutlet UITextField *numberField;//要把这两项和File's Owner做连接，即作为File's Owner的输出口  
  
- (IBAction) textFieldDoneEditing: (id)sender; // 通过Done关闭键盘  
  
- (IBAction) backgroundTap: (id)sender;//通过点击空白处关闭键盘 

把UIView的父类改为UIControl，这样就才能用空白处关闭键盘

viewController的实现中:

- (IBAction) textFieldDoneEditing: (id)sender {  
    [sender resignFirstResponder];  
}  
  
- (IBAction) backgroundTap: (id)sender {  
    [self.nameField resignFirstResponder];  
    [self.numberField resignFirstResponder];  
}

选中textField，点击连接，点击 Did End On Exit ，从加号处，拖动线到File's Owner对应的方法

 

点击UIView（即viecontroller的空白处，点击左侧的身份检查，吧父类改成UIcontrol默认的是Uiview，这是就会在connection中有各种touch方法），点击连接，点击Touch Down，从加号处，拖动线到File's Owner对应的方法

 

OK~~
