I am coding some dummy apps to get an understanding for iOS this one such app is a TODO list. I get the following error when I click the button to add a new task.

I have no idea where to even start, the list stores names emails and etc when adding a task
This is my AddTaskViewController header
#import <UIKit/UIKit.h>
#class TaskListViewController;
#interface AddTaskViewController : UITableViewController
-(IBAction)cancelButtonPressed:(id)sender;
-(IBAction)doneButtonPressed:(id)sender;
#property (nonatomic,strong) IBOutlet UITextView *nameField;
#property (nonatomic,strong) IBOutlet UITextView *emailField;
#property (nonatomic,strong) IBOutlet UITextView *homeField;
#property (nonatomic,strong) IBOutlet UITextView *cellField;
#property (nonatomic,strong) IBOutlet UITextView *addressField;
#property (nonatomic,strong) IBOutlet UITextView *notesField;
#property (nonatomic,strong) IBOutlet UITextView *dateField;
#property (nonatomic,strong) IBOutlet TaskListViewController * taskListViewController;
#end
Thank you I am so confused :(
I think you have changed your IBOutlet Name email to emailField.So you need to reconnect your IBOutlet in your xib.So please click on File's Owners control+left click at that time you will see different color on your connectivity.So reconnect you IBOutlet.
I hope it will be helpful.
Try reconnecting all your UIElements in that class.

I'm currently developing an application that displays ads. The main view controller has 2 UIViews that act as containers for the ad views that will be passed in when they are loaded. However, I'm using an API that only takes a single "adContainer" as a parameter, so tried using an IBOutlet Collection called adContainer that has each of these 2 UIViews (adContainer1 and adContainer2) linked to it. I tagged each of these so that on the main view controller when I try to load an ad, I can iterate through the adContainers in the IBOutlet Collection and request each adContainer individually based on the object's tag. I'm being thrown this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance
Here is the code for my viewController.h :
#import <UIKit/UIKit.h>
#import "MPAdView.h"
#import "MPViewController.h"
#class MPAdInfo;
#interface MPSmaatoScrollBannerAdDetailViewController :
UIViewController <MPAdViewDelegate>
#property (weak, nonatomic) IBOutlet UILabel *titleLabel;
#property (weak, nonatomic) IBOutlet UILabel *IDLabel;
#property (weak, nonatomic) IBOutlet UILabel *failLabel;
#property (weak, nonatomic) IBOutlet UIActivityIndicatorView *spinner;
#property (strong, nonatomic) IBOutletCollection(UIView) NSArray
*adViewContainer;
- (id)initWithAdInfo:(MPAdInfo *)info;
#end
And here is the function in my viewController.m that I suspect is throwing the error:
- (void)configureAd
{
for (UIView *ad in _adViewContainer) {
if (ad.tag == 1) {
self.adView1 = [[MPSampleAppInstanceProvider sharedProvider] buildMPAdViewWithAdUnitID:self.info.ID
size:ad.bounds.size];
self.adView1.delegate = self;
self.adView1.accessibilityLabel = #"smaato banner";
self.adView1.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[ad addSubview:self.adView1];
[self.adView1 stopAutomaticallyRefreshingContents];
} else if (ad.tag == 2) {
self.adView2 = [[MPSampleAppInstanceProvider sharedProvider] buildMPAdViewWithAdUnitID:self.info.ID
size:ad.bounds.size];
self.adView2.delegate = self;
self.adView2.accessibilityLabel = #"smaato banner";
self.adView2.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[ad addSubview:self.adView2];
[self.adView2 stopAutomaticallyRefreshingContents];
}
}
}
Please help! Thank you in advance!
According to the way you said, I did not report an error myself; it may be that your xib cable is not set correctly.
You can refer to this：

Hi I need to integrate date picker with inputView, I am on Xcode7. Using below code the application cause exception. The exception happening while I am touching UITextField element.
Here is the relevant part of the code where the date picker used.
#property (weak, nonatomic) IBOutlet UIDatePicker *graphDate;
#property (weak, nonatomic) IBOutlet UITextField *fromdate;
#property (weak, nonatomic) IBOutlet UITextField *toDate;
............................................................
..............................................................
[_graphDate setDatePickerMode:UIDatePickerModeDateAndTime];
............................................................
..............................................................
[_graphDate setHidden:TRUE];
[_graphDate setFrame:CGRectMake(600, 600, 400, 162)];
_toDate.inputView = _graphDate;
_fromdate.inputView = _graphDate;
_graphDate.date = [NSDate date];
The exception message,
Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason:
'child view controller:<UICompatibilityInputViewController: 0x80286850>
should have parent view controller:<VALiveViewController: 0x7cbeda00>
but requested parent is:<UIInputWindowController: 0x7cc25a00>'
I already refereed the answer here UIViewControllerHierarchyInconsistency in 64 bit iOS device but no idea how to apply here, I am newbie in IOS.
Any help will be appreciated.
Thanks,

I added a view to my app that I open from a button and can't find what I'm doing wrong.
I triple checked that dataSource & delegate are connected to File's Owner
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<HelpViewController 0xab58980> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key Picker.'
The code in my viewcontroller.h
#interface LanguageSelectionViewController : UIViewController {
IBOutlet UILabel *label;
IBOutlet UIPickerView *Picker;
NSArray *PickerData;
}
#property (retain, nonatomic) IBOutlet UIPickerView *Picker;
#property (retain, nonatomic) NSArray *PickerData;
#end
Anyone got a solution or a tip in the right direction?
Go to your storyboard click the helpviewcontroller (the whole thing so you have a blue outline around the view) now with the utility toolbar (toolbar on the right) click the arrow (the right most icon) you should see a ! mark on one of the connections. Delete that and it should work.
I have a table view with a list of categories that I would like the user to be able to select in order to rate. I've created a separate UIView (RateView) to manage the ratings within the detailviewcontroller.
I'm able to get the ratings to work fine when developing independently of the project and without a table. However, when incorporating the code for tracking ratings into storyboard and with a table, I receive the following error when attempting to navigate from the table to the detail view:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setNotSelectedImage:]: unrecognized selector sent to instance 0xad9b280' (notSelectedImage is a property of the UIView titled RateView).
Below are the interface files for each of the referenced view controllers.
* RatingsList_ViewController *
#import <UIKit/UIKit.h>
#import "Rate_ViewController.h"
#interface RatingsList_ViewController : UITableViewController
- (IBAction)dismissModal:(id)sender;
#end
Here is the SEGUE within the table to Rate_ViewController
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self performSegueWithIdentifier:#"toRateDetail" sender:self];
Rate_ViewController *rateCategory;
rateCategory = (Rate_ViewController *) self.navigationController;
}
* Rate_ViewController *
#import <UIKit/UIKit.h>
#import "RateView.h"
#interface Rate_ViewController : UIViewController <UITextFieldDelegate, RateViewDelegate>
#property (weak, nonatomic) IBOutlet RateView *rateView;
#property (weak, nonatomic) IBOutlet UILabel *statusLabel;
#property (weak, nonatomic) IBOutlet UITextField *notesField;
#end
I suspect that I've not delegated properly but any assistance you could provide would be most appreciated.
Thanks in advance!
