this line 509 is NSDictionary *dict = [[NSDictionary alloc ....

Answer 1

Look closely at line 8 in the stack trace, the FormViewController resultUpload: method.

The best guess is that one of the objects file FormViewController.m line 509 is pointing to is over-released. This type of error does not always occur depending on memory usage/re-usage.

Check at each of these is valid: userId, pseudoField.text, birthdateField.text,sex,countryField.text,cityField.text,mail,token,tokenExp, tokenExp, altitude, longitude, pictureLink.

Set NSZombies in the scheme to help find this:

Many error do not occur every time and in every configuration. In this case it appears that the device configuration is uncovering an error in your code that by luck does not appear in the simulator. Also, the simulator has a different runtime than the device which may cause an error to appear in one and not the other.

Also, is there a crash log in addition to the stack trace?

Answer 2

I believe you have an error in your conditional statements.

if([responseString isEqualToString:@"error"])
{
   NSDictionary *dict = [[NSDictionary alloc initWithObjectsAndKeys:userId, @"userID", pseudoField.text, @"pseudo", birthdateField.text,@"birthdate",sex,@"sex",countryField.text,@"country",cityField.text,@"city",mail,@"mail",token,@"token",tokenExp,@"token", tokenExp,@"tokenEpr", altitude,@"altitude",longitude,@"longitude",pictureLink,@"pic", nil];

      NSLog(@"Validated Data %@ : ",dict);
   // [pictureLink release];

    AnalyseViewController *analyseViewController =[[AnalyseViewController alloc]initWithNibName:@"AnalyseViewController" bundle:nil];
    analyseViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentModalViewController:analyseViewController animated:YES];


}
else
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Erreur De Connexion" message:@"l'application n'arrive pas à se connecter au serveur " delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok",nil];
    [alert show];

}

This will create the dictionary if your response string is @"error". Try if(![responseString isEqualToString:@"error"]).
