存储在“测试”中的对象的潜在泄漏

Question

I am working on an app in Xcode and I need some help.

- (IBAction)test:(id)sender {
    game *test = [[game alloc] initWithNibName: nil bundle: nil];

    [self presentViewController:test animated:YES completion:nil];
}    

I am getting the following error and I don't know how to fix it.

Potential leak of an object stored into "test"

Answer 1

If not using ARC, you should autorelease your object:

game *test = [[[game alloc] initWithNibName: nil bundle: nil] autorelease];

When you present the controller, it will be retained for you, but when you dismiss it, it will automatically be released for you. Your current code will probably result in a leak (unless you manually release elsewhere). Using autorelease (or explicitly release after presentViewController ) will prevent both the warning as well as the leak.

Answer 2

if you are not used the ARC, so you can need to autorelease the objcet.

when you are making the objcet then it's reatin count get be increment by 1. but after your work is done your retain count not being decreases that's why this error (leak) happen. so if you you used the autorelease then autorelease pool manage your retain count after dismiss the viewcontroller decreases the retain count .
