Вот два метода, которые возвращают словарь моих пользовательских объектов. Они создают массивы строк, чисел с плавающей запятой и BOOL для размещения объектов Chemical, а затем строят словарь из массивов. Я достаточно новичок во всей игре по управлению памятью, поэтому не всегда уверен, когда у меня есть что-то, а когда - выпустить. Я делаю все виды струн на лету.
Вот в чем дело: статический анализатор не видит проблем с первым методом, - (id)generateChlorineDictionary, но говорит, что во втором, - (id)generateCYADictionary, есть утечка. Он говорит, что начинается с NSMutableArray *cyaGranulesArray..., затем переходит к NSDictionary *cyaDictionary... и, наконец, к оператору return cyaDictionary.
Вот два метода; извините, они так долго!
