如何获取键盘大小以调整 UITextView
的大小以及如何在日文键盘上使用 UIKeyboardFrameEndUserInfoKey
?以下调整 UITextView
大小的代码在标准键盘上运行良好。但不适用于日语。如何解决?
- (void)keyboardWillShow:(NSNotification *)aNotification {
[self moveTextViewForKeyboard:aNotification up:YES];
}
- (void)keyboardWillHide:(NSNotification *)aNotification {
[self moveTextViewForKeyboard:aNotification up:NO];
}
- (void) moveTextViewForKeyboard:(NSNotification*)aNotification up: (BOOL) up
{
NSDictionary* userInfo = [aNotification userInfo];
// Get animation info from userInfo
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
CGRect keyboardEndFrame;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];
// Animate up or down
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];
CGRect newFrame = textView.frame;
CGRect keyboardFrame = [self.view convertRect:keyboardEndFrame toView:nil];
newFrame.size.height -= keyboardFrame.size.height * (up? 1 : -1);
textView.frame = newFrame;
[UIView commitAnimations];
}
非常感谢您的帮助!
最佳答案
正确的代码片段:
CGRect newFrame = editSource.frame;
CGRect keyboardFrame = [self.view convertRect:keyboardEndFrame toView:nil];
keyboardFrame.size.height -= tabBarController.tabBar.frame.size.height;
if (up) {
editHeight = newFrame.size.height;
newFrame.size.height -= keyboardFrame.size.height;
} else {
newFrame.size.height = editHeight;
}
editSource.frame = newFrame;
警告!
