You are trying to access a CALayer object that has already been released. Make sure you release the objects properly. Also ensure that [super dealloc]; is not called before other objects are released

Iphone 5s iOS 8.1.2 View Controller Loading Map from XIB, crashes

We are seeing this on ONLY iPhone 5s with iOS 8.1.2. Other devices with 8.1.2 seem to be working fine.
The view controller that has a Map loading from an XIB is init fine, but when tries to load we get... Will be trying some things to try and get around this, but any help would be appreciated.

[ADDITION]
With XCode 6.1.1 (don't think this matters, but might) with this small program (sample single view) exhibits the same issue on the 5s. It's really the init that does it.
//
// ViewController.m
// testingmap
//
#import "ViewController.h"
#import <MapKit/MapKit.h>
#interface ViewController ()
#property (nonatomic) MKMapView *mapView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.mapView = [[MKMapView alloc] init];
[self.view addSubview: self.mapView];
}
So, my iPhone was the phone in question and everything got fixed by just resetting all settings.
Settings-> General-> Reset-> Reset All Settings.
i hope it.this links useful for you. taking a time for getting map data. so you will put in view did appear and at the same time are you use xcode 6.0 and above version. ios 8 and above version. can you use this
It is Step For Map Data getting above ios 8.0 version

How to fix _CTServerConnectionRegisterForNotification crash happening in VAFieldTest application

I am trying to run VAFieldTest application in my device, but the application got crashed at this line _CTServerConnectionRegisterForNotification. How can I fix this crash?
Here are the parameters I have passed:
CTServerConnectionRef conn;
void register_notification(){
if (!mach_port || !conn) return;
void *libHandle = dlopen("/System/Library/Frameworks/CoreTelephony.framework/CoreTelephony", RTLD_LOCAL | RTLD_LAZY);
void *kCTCellMonitorUpdateNotification = dlsym(libHandle, "kCTIndicatorsSignalStrengthNotification");
if( kCTCellMonitorUpdateNotification== NULL) NSLog(#"Could not find kCTCellMonitorUpdateNotification");
int x = 0; //placehoder for callback
_CTServerConnectionRegisterForNotification(conn,kCTCellMonitorUpdateNotification,(void*)&x);
}

Thanks
You have probably tried to access an object which has been released. Search for "NSZombieEnabled" and read up on how to debug over-release problems.
The problem is you are over-releasing objects. Since you're using retain-properties you haven't to release the object when assigning a new object to the property. The old object will be released automatically. So these lines make no sense, delete them:
if (self.recipesArray != nil) {
// Release the arrays
[self.recipesArray release];
[self.recipesNames release];
}
In cellForRowAtIndexPath (RecipesListController) you are releasing rowString. There's no need to do that here. Delete that line and everything should work properly.
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
self.recipesArray = dict;
[dict release];
in your RecipesListController.m file check 55 line in viewwill appear you are release the object that you never give memory
when i make comment to
//[self.recipesArray release];
//[self.recipesNames release];
then it crash on tableview row check it

UITextField crashes app when entering apostrophe (')

my application is crashing when I enter an ' (apostrophe) in the textfield. Can anyone please tell the solution for the problem. Below is the place where it crashes
hotelTextfield.text = [hotelList objectAtIndex:indexPath.row];
I entered other strings in the textfield but those didn't cause any issue. But whenever I enter some ', it crashes.
Please find the stack backtrace for the crash

OK, the problem is solved. It was due to the SQLite. the Sqlite wasn't able to handle the apostrophe('). Solved it by adding an extra ' before sending it to the SQLite.

tableview - unrecognized selector sent to instance

I'v just got this error in my app.
2010-04-06 03:58:55.505 EasyPay DPS[6530:207] *** -[NTItems tableView]:
unrecognized selector sent to instance 0x397af90

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:
'*** -[NTItems tableView]: unrecognized selector sent to instance 0x397af90'
This error is extremely unuseful - where do I start in my code?

Your problem is in viewDidLoad on line 38.
Double-check method names, receiver names, etc.
Try adding a tableView property or method to NTItems before calling it, or derive from UITableViewController so the method is defined for you.
