UIViewControllerHierarchyInconsistenza arresta l'applicazione solo in iOS 8 e Xcode 6

Question

Ho un'app che funziona perfettamente con iOS 7 e Xcode 5. Non appena l'ho aggiornata su iOS 8 e Xcode 6 si blocca quando l'app tenta di far scorrere UIDatePicker nel visualizza quando viene toccato un campo di testo. Sto usando lo storyboard. Qualcuno ha idea del perché?

ho letto su questo ma è per Xib.

App crashes on IOS 6 - UIViewControllerHierarchyInconsistency

favore aiutatemi grazie

il mio codice:

- (void)textFieldDidBeginEditing:(UITextField *)textField 
{ 

    //set picker color start 
    [self.myDatePicker setBackgroundColor:[UIColor greenColor]]; 


    //set picker color finish 
    //calculate bounds start 
    CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField]; 
    CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view]; 
    //calculate bounds finish 
    //calculate the fraction between the top and bottom of the middle section for the text field's midline start 
    CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height; 
    CGFloat numerator = midline - viewRect.origin.y 
    - MINIMUM_SCROLL_FRACTION * viewRect.size.height; 
    CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) 
    * viewRect.size.height; 
    CGFloat heightFraction = numerator/denominator; 
    //calculate the fraction between the top and bottom of the middle section for the text field's midline finish 
    //Clamp this fraction so that the top section is all "0.0" and the bottom section is all "1.0 start 
    if (heightFraction < 0.0) 
    { 
     heightFraction = 0.0; 
    } 
    else if (heightFraction > 1.0) 
    { 
     heightFraction = 1.0; 
    } 
    //Clamp this fraction so that the top section is all "0.0" and the bottom section is all "1.0 finish 
    /*start 
    Now take this fraction and convert it into an amount to scroll by multiplying by the keyboard height for the current screen orientation. Notice the calls to floor so that we only scroll by whole pixel amounts */ 
    UIInterfaceOrientation orientation = 
    [[UIApplication sharedApplication] statusBarOrientation]; 
    if (orientation == UIInterfaceOrientationPortrait || 
    orientation == UIInterfaceOrientationPortraitUpsideDown)

    } 
    else

Answer 1

-(void)viewDidLoad 
       { 
      //init and allocate(my problem was addind nil object into view.   
     self.myDatePicker = [[UIDatePicker alloc]init]; 

        [self.myDatePicker setDatePickerMode:UIDatePickerModeCountDownTimer]; 

     //to get text off picker 
        [self.myDatePicker addTarget:self action:@selector(textFieldDidEndEditing:) forControlEvents:UIControlEventValueChanged]; 

     //to hide picker 
        _tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)]; 
       } 


    -(BOOL)textFieldShouldEndEditing:(UITextField *)textField 
       { 
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init]; 
        [dateFormat setDateFormat:@"HH:mm"]; 
        NSDate *date = self.myDatePicker.date; 
        //or select pickerViewMode 

        switch (textField.tag) 
       { 
        case 1: //pulls selected text into textField 
         self.textField1.text = [dateFormat stringFromDate:date]; 
         break; 
       } 
       } 

    -(void)hideKeyboard 
       { 
       //NSLog(@"6 hideKeyboard"); 
       [self.textField1 resignFirstResponder]; 
       } 

Answer 2

La base pro blem era probabilmente causato dall'aggiunta del selettore di date come visualizzazione secondaria della vista dei controller della vista.

Rimozione la seguente riga avrebbe impedito questo:

[self.view addSubview:self.myDatePicker]; 

vedere https://stackoverflow.com/a/25831317/1871400

Answer 3

Il problema è che bisogna garantire tutti i inputAccessoryView non appartengono ad alcuna vista primaria. Riferimento: Error when adding input view to textfield iOS 8.

Answer 4

selezione data non dovrebbe essere bambino di qualsiasi super-vista

Problema:

È necessario garantire che la vista che si assegnerà al inputView o inputAccessoryView non appartengono ad alcuna vista primaria. Forse quando crei queste viste da xib all'interno di un ViewController, per impostazione predefinita sono subviews di una superview.

Consigli Soluzione:

utilizzando il metodo removeFromSuperview per la vista si assegnare ai inputView o inputAccessoryView

vedi dettaglio in questo link

Answer 5

O si creano selezione data programatically o se lo si utilizza come componente trascinato, eseguire i passaggi indicati di seguito

1.Creare Programatically

datePicker = [[UIDatePicker alloc]init]; 
[datePicker setDate:[NSDate date]]; 
//NSString *maxDateString = @"01-Jan-2012"; 
NSString *theMinimumDate = @"01-Jan-1976"; 
// the date formatter used to convert string to date 
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
// the specific format to use 
dateFormatter.dateFormat = @"dd-MMM-yyyy"; 
// converting string to date 
NSDate *theMaximumDate = [NSDate date];//[dateFormatter dateFromString: maxDateString]; 
NSDate *theminimumDate = [dateFormatter dateFromString: theMinimumDate]; 

// repeat the same logic for theMinimumDate if needed 
// here you can assign the max and min dates to your datePicker 
[datePicker setMaximumDate:theMaximumDate];//the max age restriction (if needed, or else dont use this line) 
[datePicker setMinimumDate:theminimumDate]; //the min age restriction 

// set the mode 
[datePicker setDatePickerMode:UIDatePickerModeDate]; 
// Do any additional setup after loading the view from its nib. 
[datePicker addTarget:self action:@selector(updateTextField:) forControlEvents:UIControlEventValueChanged]; 

// and finally set the datePicker as the input mode of your textfield 
[Textfield setInputView:datePicker]; 

2.From Xib

[self.DatePickerView removeFromSuperview]; 
[Textfield setInputView:self.DatePickerView]; 
[Textfield setInputView:self.DatePickerView];
