I created a toolbar above the picker with two buttons and worked on ios7, when i run in ios8 crash:
Terminating app two to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller: Should Have parent view controller: but requested parent is: '
This is the piece of code that worked quietly in ios7:
expiredPromoTextField.inputView = DatePicker;
expiredPromoTextField.delegate = self;
quantityPromoTextField.inputView = quantityPicker;
quantityPromoTextField.delegate = self;
// Create button to close the UIPickerView
UIToolbar * mypickerToolbar = [[UIToolbar alloc] initWithFrame: CGRectMake (0, 0, 320, 56)];
mypickerToolbar.barStyle = UIBarStyleBlackTranslucent;
[mypickerToolbar sizeToFit];
NSMutableArray * barItems = [[NSMutableArray alloc] init];
UIBarButtonItem * CancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemCancel target: self action:selector (cancelDoneClicked)];
[barItems addObject: CancelBtn];
UIBarButtonItem * FLEXspace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target: self action: nil];
[barItems addObject: FLEXspace];
UIBarButtonItem * doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemDone target: self action:selector (pickerDoneClicked :)];
[barItems addObject: doneBtn];
[mypickerToolbar setItems: barItems animated: YES];
[quantityPicker setShowsSelectionIndicator: YES];
expiredPromoTextField.inputAccessoryView = mypickerToolbar;
quantityPromoTextField.inputAccessoryView = mypickerToolbar;
You know what I realized is that inputAccessoryView
is going to crash the app, I also asked engineers of Apple and they told me that it was a problem with the beta, but now with the GM continues to give the same problem.
What do I do?
I had the same exception on iOS 8 and now fixed as the following codes.
The point is, you should not add an input view as a child view of view controller's view. (I have no idea why the code worked well in iOS 7 is no longer working well in iOS 8.)
Before (occurs error)
UITextField* someTF;
View* customView;
UIViewController *mainVC;
[mainVC.view addSubview:customView];
someTF.inputView = customView;
After (working well)
UITextField* someTF;
View* customView;
UIViewController *mainVC;
// [mainVC.view addSubview:customView]; <-- delete this line
someTF.inputView = customView;
