So, as often suggested for people who want the view to be pushed up when the keyboard appears, I use a UIScrollView. I copied and pasted the information from this page -- http://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW7 -- to do that...
But what happens is, when I tap the text fields, the keyboard pops up, but the view actually scrolls DOWN, revealing black on top. After that, I can actually manually scroll the view up and reveal the hidden text fields...obviously, that's not what I'm trying to do!
Any ideas? I have the following in the viewDidLoad() method:- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillBeHidden:) name:UIKeyboardWillHideNotification object:nil];
}
I've tried this version of keyboardWasShown:
- (void) keyboardWasShown:(NSNotification *)aNotification
{
NSDictionary * info = [aNotification userInfo];
CGSize keyboardSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 0,keyboardSize.height, 0);
[[self introScroll] setContentInset:contentInsets];
[[self introScroll] setScrollIndicatorInsets:contentInsets];
CGRect ltdRect=[[self view] frame];
ltdRect.size.height=keyboardSize.height;
if (!CGRectContainsPoint(ltdRect,[self activeField].frame.origin))
{
CGPoint scrollPoint = CGPointMake(0,[self activeField].frame.origin.y-keyboardSize.height);
[[self introScroll] setContentOffset:scrollPoint animated:YES];
}
NSLog(@"Keyboard out!");
}
as well as this version of keyboardWasShown:
- (void)keyboardWasShown:(NSNotification*)aNotification {
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CGRect bkgndRect = [[[self activeField] superview ]frame];
bkgndRect.size.height += kbSize.height;
[[[self activeField] superview] setFrame:bkgndRect];
[[self introScroll] setContentOffset:CGPointMake(0.0, [self activeField].frame.origin.y-kbSize.height) animated:YES];
}
Both give me the exact same results.
What's going on?? I'm using Xcode 4.6.
