iOS之隐藏键盘的方式

一、//触摸空白处隐藏键盘

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

[_feedBackTextView resignFirstResponder];

[_telTextField resignFirstResponder];

}

二、添加点按手势 隐藏键盘

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]  initWithTarget:self action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];

- (void)dismissKeyboard {

[self.userText resignFirstResponder];

[self.passWordText resignFirstResponder];

}

三、//在键盘上方添加一个完成按钮来收起键盘

UIToolbar * topView = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 30)];

[topView setBarStyle:UIBarStyleDefault];

//定义两个flexibleSpace的button，放在toolBar上，这样完成按钮就会在最右边

UIBarButtonItem * button1 =[[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:self action:nil];

UIBarButtonItem * button2 = [[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:self action:nil];

//定义完成按钮

UIBarButtonItem * doneButton = [[UIBarButtonItem alloc]initWithTitle:@"完成" style:UIBarButtonItemStyleDone target:self action:@selector(resignKeyboard)];

//在toolBar上加上这些按钮

NSArray * buttonsArray = [NSArray arrayWithObjects:button1,button2,doneButton,nil]; [topView setItems:buttonsArray];

[_feedBackTextView setInputAccessoryView:topView];

[_telTextField setInputAccessoryView:topView];

//隐藏键盘

- (void)resignKeyboard {

[_feedBackTextView resignFirstResponder];

[_telTextField resignFirstResponder];

}
