Я пробовал приведенный ниже код, но [self performSelector:handler withObject:data afterDelay:0] в функции синхронизации не вызывает методы handler1 или handler2, даже когда я передаю обработчики из метода initWithType. Обработчик не обнуляется. Я уже проверил это.
Может кто-нибудь сказать мне, что идет не так?
- (instancetype)initWithType:(NSInteger *)Handler
{
switch(Handler)
{
case 0:
[self sync:@selector(handler1:) withURL:SyncURL];
break;
case 1:
[self sync:@selector(handler2:) withURL:SyncURL];
break;
default:
break;
}
