Help - Я застрял в Objective-C / iOS Purgatory ...
ISSUE : Когда я присваиваю значения переменным экземпляра, которые могут передавать значения между полученными контроллерами представления "дополнительные данные XML "(т.е. - данные-призраки).Пожалуйста, смотрите скриншот ниже.
Я думаю, что это утечка памяти.Ваши мысли?
Снимок экрана с результатами: 
Вот код:
-(void)parserDidEndDocument:(NSXMLParser *)parser
{
itemNotFound = [[NewItemViewController alloc]
initWithNibName:@"NewItemViewController"
bundle:nil];
itemFound = [[ItemViewController alloc]
initWithNibName:@"ItemViewController"
bundle:nil];
// If # of items from Google API request equals zero, then go to User Generated Item Screen
if ( totalResults == @"0") {
[self.view addSubview:itemNotFound.view];
} else {
[self.view addSubview:itemFound.view];
}
[totalResults release];
totalResults = nil;
// Added 7-13-2011: Assign UPC code to a variable to use in Item View
NSString *upcItem = [[NSString alloc]
initWithString:itemNumber];
NSString *titleItem = [[NSString alloc]
initWithString:itemDesc];
NSString *brandItem = [[NSString alloc]
initWithString:itemBrand];
NSString *storeItem = [[NSString alloc]
initWithString:itemStore];
NSString *imageItem = [[NSString alloc]
initWithString:[itemImagesArray objectAtIndex:0]];
self.itemFound.upcScanned = upcItem;
self.itemFound.titleScanned = titleItem;
self.itemFound.brandScanned = brandItem;

ОБНОВЛЕНИЕ : Основываясь на отзывах от dragon112 , я исправил проблему с "строковым литералом" ...
ИСПРАВЛЕНО: я анализирую вызов Google API.По результатам я хотел бы загрузить один из двух контроллеров представления.Если «итоговые результаты» = 0, загрузите «NewItemVC», иначе загрузите «ItemVC».
