Question

我已将UITextField和UITextView添加到UIWindow内我无法在其中输入内容。两者都不允许我输入这些字段。并且，在键盘中按 return 时无法将其解除。

-(void)showAlert 
{
alertWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
alertView = [[UIView alloc] initWithFrame:CGRectMake(10, 115, 300, 230)];
alertWindow.windowLevel = UIWindowLevelAlert; // puts it above the status bar
alertView.center = CGPointMake(alertWindow.frame.size.width/2, alertWindow.frame.size.height/2);
alertView.backgroundColor = [UIColor whiteColor];
alertView.layer.borderWidth = 1.0;
alertView.layer.borderColor = [[UIColor whiteColor]CGColor];

UITextField *txt = ....
....
....
txt.delegate = self;
...
...
[alertView addSubview:txt];

UITextView *txtview = ...
....
....
txtview.delegate = self;
...
[alertView addSubview:txtview];

[alertWindow addSubview:alertView];
[alertWindow addSubviewWithZoomInAnimation:alertView duration:1.0 option:curveValues[0]];
[alertWindow setHidden:NO];
}

我也声明了两种委托方法。我在那里放了一个断点并检查，即使那个方法还没有调用。

更新 -

textFieldShouldReturn委托方法

- (BOOL) textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    [reserveView resignFirstResponder];
    [reserveWindow resignFirstResponder];
    [self.reserveWindow endEditing:YES];
    [reserveView endEditing:YES];
    return YES;
}

Answer 1

您应该尝试将其从UIWindow

中解除键盘

[self.window endEditing:YES];

Answer 2

我发现，由于UIWindow而没有调用该方法所以，我将UIWindow更改为UIView而且，我使用UIView+Animation.h来解决此问题{3}}它提供了我所需要的动画。

- (void) addSubviewWithZoomInAnimation:(UIView*)view duration:(float)secs option:(UIViewAnimationOptions)option;
- (void) removeWithZoomOutAnimation:(float)secs option:(UIViewAnimationOptions)option;

感谢Google！干杯！

Answer 3

键盘永远不会自行解散（即使你点击了返回！）。您会注意到，在您的委托方法中，只要按下return / done / etc。

，就会收到事件

每次有人点击返回键时，键盘关闭的一种简单方法是实现- (BOOL)textViewShouldEndEditing:(UITextView *)textView方法。

- (BOOL)textViewShouldEndEditing:(UITextView *)textView { [textView endEditing:YES]; return YES; }

编辑：在你编辑的帖子中，你说你已经宣布了两种委托方法......有两种以上所以你能澄清一下你实施的方法吗？ http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextViewDelegate_Protocol/Reference/UITextViewDelegate.html#//apple_ref/occ/intf/UITextViewDelegate

Answer 4

试试这个

- (void)viewDidLoad
{
  [super viewDidLoad];
  UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
  tapGesture.cancelsTouchesInView = NO;
  [self.window addGestureRecognizer:tapGesture];
  //[self.view addGestureRecognizer:tapGesture];
  [tapGesture release];
}
-(void)dismissKeyboard
{
[txt resignFirstResponder];
[textView resignFirstResponder];
}

Answer 5

试试这个

这是textfield的委托方法： -

（BOOL）textFieldShouldReturn：（UITextField *）textField

{
```
[txtview resignFirstResponder];
```
返回NO;

}

当UITextField和UITextview显示在UIWindow内部时，解散键盘
