Custom UIPickerView crash in iOS 7 - ios

Question

I had made a Custom UIPickerView with three Components each showing label on Selection Indicator which is working fine in iOS 6.
But I am getting a crash in iOS 7.
Here is my code:
ViewController.h
#define kDaysComponent 0
#define kHoursComponent 1
#define kMinutesComponent 2
#import <UIKit/UIKit.h>
#import "LabeledPickerView.h"
#interface ViewController : UIViewController<UIPickerViewDataSource,UIPickerViewDelegate,UITextFieldDelegate>
{
NSMutableArray *arrDays;
NSMutableArray *arrHours;
NSMutableArray *arrMinutes;
LabeledPickerView *timePicker;
IBOutlet UITextField *txtTimeLimit;
}
#property(nonatomic, retain) NSMutableArray *arrDays;
#property(nonatomic, retain) NSMutableArray *arrHours;
#property(nonatomic, retain) NSMutableArray *arrMinutes;
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize arrDays;
#synthesize arrHours;
#synthesize arrMinutes;
- (void)viewDidLoad
{
self.arrDays = [[NSMutableArray alloc]initWithCapacity:100];
for (NSInteger i = 0; i < 100; i++){
[arrDays addObject:[NSString stringWithFormat:#"%d",i]];
}
//self.arrDays = arrDays;
self.arrHours = [[NSMutableArray alloc]initWithCapacity:24];
for (NSInteger i = 0; i < 24; i++){
[arrHours addObject:[NSString stringWithFormat:#"%d",i]];
}
//self.arrHours = arrHours;
self.arrMinutes = [[NSMutableArray alloc]initWithCapacity:60];
for (NSInteger i = 0; i < 60; i++){
[arrMinutes addObject:[NSString stringWithFormat:#"%d",i]];
}
//self.arrMinutes = arrMinutes;
[self.navigationController setNavigationBarHidden:YES];
[super viewDidLoad];
}
-(IBAction)Click:(id)sender{

timePicker.delegate = self;
[timePicker addLabel:#"Days" forComponent:kDaysComponent forLongestString:#"Hours"];
[timePicker addLabel:#"Hours" forComponent:kHoursComponent forLongestString:#"Hours"];

//custom input view
txtTimeLimit.inputView = timePicker;
txtTimeLimit.inputAccessoryView = toolbar;
}

I am showing UIPickerView as an input view for UITextField and each time I am getting this error in iOS 7 only:
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 5 beyond bounds [0 .. 2]'
I don't know what's wrong with it. Can anyone please help me on this?

Answer 1

Your crash is telling you what the problem is:
-[__NSArrayM objectAtIndex:]: index 5 beyond bounds [0 .. 2]'
You are trying to get a value of object at the index 5 when your array only contains 3 objects.
Put a break point in and check the arrays contain what you expect and the component value is what you expect.

Answer 2

Please try to set txtTimeLimit.inputView after delays like one second.
[self performSelector:#selector(setInputView:) withObject:timePicker afterDelay:1];
- (void)setInputView:(LabeledPickerView*)picker {
txtTimeLimit.inputView = picker;
}
I think it's something doing with the animation....

Answer 3

You have to concern in few things,
First is the delegate and datasource method.
If u get the warning on delegate and datasource then correct the code like this
timePicker.dataSource = (id)self;
timePicker.delegate = (id)self;
Then Check the array. Hopefully it will solve your problem.
