hi guys
i have a simple app, it consist of 2 textview, 1 uiview as a coretext subclass, and then 1 scrollview. the others part is subviews from scrollview. I use this scrollview because i need to scroll the textviews and uiview at the same time. I already scroll all of them together, but the problem is, the keyboard hiding some lines in the textview. I have to change the frame of scrollview when keyboard appear, but it still not help.
This is my code :
UIScrollView *scrollView;
UIView *viewTextView;
UITextView *lineNumberTextView;
UITextView *codeTextView;
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(keyboardWillAppear:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(keyboardWillDisappear:)
name:UIKeyboardWillHideNotification
object:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height);
scrollView.contentSize = CGSizeMake(self.view.frame.size.width, viewTextView.frame.size.height);
[scrollView addSubview:viewTextView];
CGAffineTransform translationCoreText = CGAffineTransformMakeTranslation(60, 7);
[viewTextView setTransform:translationCoreText];
[scrollView addSubview:lineNumberTextView];
[self.scrollView setScrollEnabled:YES];
[self.codeTextView setScrollEnabled:NO];
}
-(void)keyboardWillAppear:(NSNotification *)notification {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:[[[notification userInfo]
objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
CGRect keyboardEndingUncorrectedFrame = [[[notification userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey ] CGRectValue];
CGRect keyboardEndingFrame =
[self.view convertRect:keyboardEndingUncorrectedFrame
fromView:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height - keyboardEndingFrame.size.height);
[UIView commitAnimations];
}
-(void)keyboardWillDisappear:(NSNotification *) notification {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:[[[notification userInfo]
objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]];
CGRect keyboardEndingUncorrectedFrame = [[[notification userInfo]
objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect keyboardEndingFrame =
[self.view convertRect:keyboardEndingUncorrectedFrame
fromView:nil];
self.scrollView.frame = CGRectMake(0, 88, self.codeTextView.frame.size.width,
self.codeTextView.frame.size.height + keyboardEndingFrame.size.height);
[UIView commitAnimations];
}
can somebody help me please?
