objective-c - 在 xcode 故事板中隐藏键盘

Question

xcode 的新手，我正在 xcode 4.2 中创建一个简单的登录表单，我想隐藏键盘，我认为我有正确的代码，从教程中它说我需要将视图的类更改为 UIControl 但那里对此没有选择，在使用故事板时还有其他方法吗？

- (IBAction)backGroundTouched:(id)sender
{
    [emailTextField resignFirstResponder];
    [passTextField resignFirstResponder];
}

Answer 1

假设您在 viewCotroller 中执行它们，请调用

[self.view endEditing:YES];

Answer 2

如果您的两个文本字段是某些更高级别视图的子视图，您也可以使用[higherLevelView endEditing];而不关心当前哪个子视图处于活动状态。

Answer 3

我遵循了本教程：http ://www.techotopia.com/index.php/Writing_iOS_7_Code_to_Hide_the_Keyboard它对我有用：

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

    UITouch *touch = [[event allTouches] anyObject];
    if ([_textField isFirstResponder] && [touch view] != _textField) {
        [_textField resignFirstResponder];
    }
    [super touchesBegan:touches withEvent:event];
}

Answer 4

Make sure your both text fields is connect with it's IBOutlets.
No need to change UIView to UIControl.

// Connect every textfield's "Did end on exit" event with this method.
-(IBAction)textFieldReturn:(id)sender
{
    [sender resignFirstResponder];


}

// Use this method also if you want to hide keyboard when user touch in background

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [emailTextField resignFirstResponder];
    [passTextField resignFirstResponder];
}
