iOS之隱藏鍵盤的方式

一、//觸摸空白處隱藏鍵盤

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

    [_feedBackTextView resignFirstResponder];

    [_telTextField resignFirstResponder];

}

二、添加點按手勢 隱藏鍵盤

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

    [self.view addGestureRecognizer:tap];

- (void)dismissKeyboard {

    [self.userText resignFirstResponder];

    [self.passWordText resignFirstResponder];

}

三、//在鍵盤上方添加一個完成按鈕來收起鍵盤

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

    [topView setBarStyle:UIBarStyleDefault];

    //定義兩個flexibleSpace的button，放在toolBar上，這樣完成按鈕就會在最右邊

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

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

    //定義完成按鈕

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

    //在toolBar上加上這些按鈕

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

    [_feedBackTextView setInputAccessoryView:topView];

    [_telTextField setInputAccessoryView:topView];

//隱藏鍵盤

- (void)resignKeyboard {

    [_feedBackTextView resignFirstResponder];

    [_telTextField resignFirstResponder];

}
