많은 시간 동안 호출 된 Objective-C 릴리즈

Question

내 루트보기 컨트롤러의 릴리스 방법은 38 번 호출되지만 release는 호출하지 않습니다. 왜 발생합니까?

@interface ViewController() 

@end 

@implementation ViewController 

-(oneway void)release 
{ 
    NSLog(@"release called"); 
    [super release]; 
} 

@end

@implementation AppDelegate 

- (void)dealloc 
{ 
    [_window release]; 
    [_viewController release]; 
    [super dealloc]; 
} 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { 
     self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease]; 
    } else { 
     self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease]; 
    } 
    self.window.rootViewController = self.viewController; 
    [self.window makeKeyAndVisible]; 
    return YES; 
}

outpout 나는 ARC를 사용하지 않는.

Answer 1

프레임 워크의 일부는 적절하다고 느끼는대로 객체를 유지하고 해제 (또는 자동 렌더링)합니다. 이것은 보유 개수를 정확하게 추적하지 않도록 권장하는 여러 가지 이유 중 하나입니다. 이러한 보유 및 릴리스가 모두 발생하는 것을 사용자가 알 필요가 없으므로 사용자와 관련이 없습니다.

Answer 2

대부분의 경우 시스템 컨트롤러를 통해 뷰 컨트롤러가 자동 복구 풀에 추가됩니다. 그러나 코드가 View Controller를 올바르게 관리하고 있다고 확신하는 한, 이것을 백그라운드 노이즈로 무시해야합니다.
