Instruments is showing me a leak in this method</p> <pre><code>-(void)loadData { if (locationData != nil) { [locationData release]; } self.locationData = [[NSMutableArray alloc] init]; NSData *recievedData = [NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://htmlwin001.******.net/blutalkasp/locations2.asp?uid=%@&amp;von=%d&amp;bis=%d", [[UIDevice currentDevice] uniqueIdentifier], von, bis]]]; NSString *recievedString = [[NSString alloc] initWithData:recievedData encoding:NSUTF8StringEncoding]; SBJsonParser *json = [[SBJsonParser alloc] init]; NSMutableDictionary *jsonData = [json objectWithString : recievedString]; NSString *tmpLocationData; for (NSDictionary *location in [jsonData objectForKey:@"items"]) { Location *newLocation = [[Location alloc] init]; tmpLocationData = [[NSString alloc]initWithFormat:@"%@", [location objectForKey:@"id"]]; [newLocation setLocationID:tmpLocationData]; [tmpLocationData release]; tmpLocationData = [[NSString alloc]initWithFormat:@"%@", [[location objectForKey:@"locationname"] gtm_stringByUnescapingFromHTML]]; [newLocation setLocationName:tmpLocationData]; [tmpLocationData release]; tmpLocationData = [[NSString alloc]initWithFormat:@"%@",[location objectForKey:@"locationdistance"]]; [newLocation setLocationDistance:tmpLocationData]; [tmpLocationData release]; tmpLocationData = [[NSString alloc]initWithFormat:@"%@", [[location objectForKey:@"locationaddress"] gtm_stringByUnescapingFromHTML]]; [newLocation setLocationAdress:tmpLocationData]; [tmpLocationData release]; tmpLocationData = [[NSString alloc]initWithFormat:@"%@", [[location objectForKey:@"locationdescription"] gtm_stringByUnescapingFromHTML]]; [newLocation setLocationDescription:tmpLocationData]; [tmpLocationData release]; NSNumber *tmpLocationLat = [[NSNumber alloc] initWithInteger:[[location objectForKey:@"locationlatitude"]integerValue]]; [newLocation setLocationPositionLat:tmpLocationLat]; [tmpLocationLat release]; NSNumber *tmpLocationLng = [[NSNumber alloc] initWithInteger:[[location objectForKey:@"locationlongitude"]integerValue]]; [newLocation setLocationPositionLng:tmpLocationLng]; [tmpLocationLng release]; NSString *URL; URL = [location objectForKey:@"locationimage1"]; URL = [URL stringByReplacingOccurrencesOfString:@"[SLASH]" withString:@"/"]; NSString *tmpUrl1 = [[NSString alloc]initWithFormat:@"http://htmlwin001.******.net/blutalkasp/locationimages/data/%@", URL]; [newLocation setLocationImageURL1:tmpUrl1]; [tmpUrl1 release]; URL = [location objectForKey:@"locationimage2"]; URL = [URL stringByReplacingOccurrencesOfString:@"[SLASH]" withString:@"/"]; NSString *tmpUrl2 = [[NSString alloc]initWithFormat:@"http://htmlwin001.******.net/blutalkasp/locationimages/data/%@", URL]; [newLocation setLocationImageURL2:tmpUrl2]; [tmpUrl2 release]; URL = [location objectForKey:@"locationimage3"]; URL = [URL stringByReplacingOccurrencesOfString:@"[SLASH]" withString:@"/"]; NSString *tmpUrl3 = [[NSString alloc]initWithFormat:@"http://htmlwin001.******.net/blutalkasp/locationimages/data/%@", URL]; [newLocation setLocationImageURL3:tmpUrl3]; //Leak geschlossen [tmpUrl3 release]; [self.locationData addObject:newLocation]; [newLocation release]; } [recievedString release]; [json release]; } </code></pre> <p>Is it possible that <code>[nsdictionaryobject objectForKey:@"xy"];</code> is causing a leak?</p> <p>Because in instrument especially these lines are coloured. As you can see I was releasing everything. I'm quite desperate with that app. I even began to replace all the convenient constructors through alloc/init/release (e.g. <code>initWithFormat</code> instead of <code>stringWithFormat</code>). Especially in loops!</p> <p>But sometimes even instruments crash!</p>
