自动隐藏软键盘,分为两步,一个是单击软键盘外部任意空间;另外一个是单击软键盘上的return键。下面依次实现
单击软键盘外部空间键隐藏软键盘:
一:在viewDidLoad中添加一个UITabGestureRecognizer,并将其添加到ViewController的view对象上
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:@selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
二:可以看到上面有一个dismissKeyboard的selector,下面实现该方法,并在方法中通过resignFirstResponder来隐藏软键盘
-(void)dismissKeyboard {
[feedbackTextField resignFirstResponder];
}
单击软键盘上的return键隐藏软键盘:
一:使ViewController实现UITextFieldDelegate协议,ViewController.h

// #import <UIKit/UIKit.h> @interface FeedBackViewController : UIViewController <UITextFieldDelegate>
@property (strong, nonatomic) IBOutlet UITextField *feedbackTextField; @end
二:在ViewDidLoad为UITextFiled指定delegate
feedbackTextField.delegate = self;
三:实现UITextFieldDelegate中的textFieldShouldReturn:方法
-(BOOL)textFieldShouldReturn:(UITextField *)textField {
[feedbackTextField resignFirstResponder];
}
