Question

My app crashes when the control comes over here [self loadNextList]. I am not sure why this happeninging. Please let me know if you see the problem.

For the first time , it works i dont see any problem. and when the loadNextList method is called again it gets crashed.when crashing no error message found in the console.

NSString *myTierTwoID;
@property(nonatomic,retain)NSString *myTierTwoID;

-(void)getData{

myTierTwoID = [myTierTwoDict objectForKey:myTierTwoTitle];

[self loadNextList];

}

-(void)loadNextList{
//==========================

  NSLog(@"%@ lloo",myTierTwoID);

  NSString *aTierTwoId = [NSString stringWithFormat:@"%d", [myTierTwoID intValue] + 1];

  NSLog(@"%@ aTierTwoId",aTierTwoId);

  myTierTwoID = aTierTwoId; // here it crashes the app

  NSLog(@"%@ lloo",myTierTwoID);
}

The property signature expects a retained value, so you should do this instead:

self.myTierTwoID = [myTierTwoDict objectForKey:myTierTwoTitle];

and

self.myTierTwoID = aTierTwoId;
