Objective-c發佈多次調用

我的根視圖控制器的發佈方法被調用了38次，但我沒有調用release，爲什麼會發生？Objective-c發佈多次調用

@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; 
}

@interface ViewController() 

@end 

@implementation ViewController 

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

@end

我不使用ARC。

您的視圖控制器對象可以由幾個框架對象傳遞。此外，即使_you_不使用ARC，也許Apple會這樣做; ARC在調用保留/釋放時並不輕鬆。無論如何，我認爲這與日誌發佈呼叫無關。只有在調用dealloc時它纔會起作用。 – zneak 2013-04-09 22:58:33
