Question

我在键盘显示事件后遇到UIScrollview问题，显然我的UITextField就像这样向上移动：

这是在键盘显示后：

我完全按照例子做了，这是我的代码：

-(void) keyboardDidShow: (NSNotification *)notif {
if (keyboardVisible) {
    NSLog(@"Keyboard is already visible. Ignoring notofication.");
    return;
}

//The keyboard wasn't visible before
NSLog(@"Resizing smaller for keyboard");

// Get the size of the keyboard.
NSDictionary* info = [notif userInfo];
NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;

// Resize the scroll view to make room for the keyboard
CGRect viewFrame = self.view.frame;
viewFrame.size.height -= keyboardSize.height;
scrollView.frame = viewFrame;
keyboardVisible = YES;}

-(void) keyboardDidHide: (NSNotification *)notif {
if (!keyboardVisible) {
    NSLog(@"Keyboard is already hidden. Ignoring notification.");
    return;
}

// The keyboard was visible
NSLog (@"Resizing bigger with no keyboard");

//Get the size of the keyboard.
NSDictionary* info = [notif userInfo];
NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;

// Reset the height of the scroll view to its original value
CGRect viewFrame = self.view.frame;
viewFrame.size.height += keyboardSize.height;

scrollView.frame = viewFrame;
keyboardVisible = NO;}

您是否尝试过使用keyboardWasShown和keyboardWasHidden而不是WillShow和WillHide？另外，我注意到你正在使用“UIKeyboardBoundsUserInfoKey”进行Show＆amp;隐藏。试试“UIKeyboardFrameBeginUserInfoKey”＆amp; “UIKeyboardFrameEndUserInfoKey”

显示键盘后，UIScrollView的孩子移动了
