奇怪的内存泄露 incorrect decrement of the reference count of an object that is not owned at this point by

LoginViewController *loginViewController = [[LoginViewController
alloc] initwithLoginUrl: loginUrl];

CustomNavigationController *customNavigationController = [[CustomNavigationController
alloc] initWithRootViewController: loginViewController];
customNavigationController.navigationBar.tintColor =
NavgaitonBar_Color;
[self.navigationController
presentModalViewController: customNavigationController
animated: YES];

[loginViewController
release];
[customNavigationController release];

红色为提示内存泄露的地方

只要把 LoginViewController *loginViewController = [[LoginViewController alloc] initwithLoginUrl: loginUrl];

修改为 LoginViewController *loginViewController = [[LoginViewController alloc] initWithLoginUrl: loginUrl];

就可以解决内存泄露
