我在显示键盘时向上移动模态视图,以防止键盘隐藏界面的某些部分。
当视图移动后,工具栏取消/保存按钮不会响应点击。检测到模态内的点击并且响应很好。
我进行了设置,以便在点击文本字段外时键盘应该关闭,但是当点击导航栏时这也不起作用。
当视图被偏移时,我如何恰当地响应barbuttonitems上的点按?
以下是我在显示键盘时向上移动模态的方法:
- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
int movementDistance;
float movementDuration;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
if(
UIInterfaceOrientationIsLandscape(self.interfaceOrientation)
)
{
//code for landscape shift - not relevant because you can't see the toolbar
else{
NSLog(@"Portrait for animation");
movementDistance = IPAD_PORTRAIT_KEYBOARD_HEIGHT;
movementDuration = KEYBOARD_ANIMATION_DURATION;
if(up){
keyboardAppearedInLandscape = false;
}else{
//the keyboard is going down
NSLog(@"Keyboard going down");
//is the iPad in the same orientation now that it was when it came up?
if ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortrait || [[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortraitUpsideDown)
{
if (!keyboardAppearedInLandscape) {
//don't do anything - the keyboard is being dismissed in the same way it was called. It's much the same in any case.
}else{
movementDistance = IPAD_LANDSCAPE_KEYBOARD_HEIGHT;
}
}
}
}
}
int movement = (up ? -movementDistance : movementDistance);
[UIView beginAnimations: @"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}
//end text field movy-ness
以下是我在文本区域外检测水龙头以解除键盘的方法:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
//keyboard goes away if you tap somewhere else on screen
NSLog(@"resignFirstResponder");
[self.view endEditing:YES];
}
[super touchesBegan:touches withEvent:event];
}

您不会收到原始矩形边界之外的触摸事件,因为......
SuperView
认为视图未更改位置SuperView
应该回复UIKeyboard
UIKeyboardWillHideNotification
&& UIKeyboardWillShowNotification
ClipsToBounds to YES

我认为您的问题是您正在自己内部移动视图,而不是从外部移动视图。因此,屏幕上的视觉元素正在发生变化,但根据您的SuperView,视图位于同一位置,因此您只能在原始矩形内获得触摸事件(此矩形称为“边界”)。
相反,您的SuperView应该响应UIKeyboardWillShowNotification
和UIKeyboardWillHideNotification
将子视图移动到正确的位置。
如果将ClipsToBounds
设置为YES
,则可以更轻松地调试此类内容。这将使你无法看到视图“边界”之外的东西(可以接收触摸事件的区域。)
