problem for getting the memory leak in frame setting

I am implementing an iPhone app.for that,creating a common view controller throughout the application and i am changing my views according to the requirements. for that i am writing the code like

addViewController = [[ProAddViewController alloc] initWithNibName:@"ProAddViewController" bundle:nil];
[addViewController.view setFrame:[[UIScreen mainScreen] applicationFrame]];
currentTabView = addViewController ;

and then when ever i want to add new view for the currentTabView, i am releasing the previous one then adding new view controller's view to the currentTabView.finally i am releasing the currentTabView in dealloc().

i am getting a memory 开发者_Python百科leak in the line shown below.

[addViewController.view setFrame:[[UIScreen mainScreen] applicationFrame]];

Can any one please help me out? Thanks in advance.

An easy way can be, if you are using the addViewController and currentTabView in a view controller, then declare them as a property, and use, self.addViewController and self.currentTabView when assigning new values. Then compiler will automatically handle releasing and deallocating. surely you have to release them in dealloc.

    self.addViewController = [[ProAddViewController alloc] initWithNibName:@"ProAddViewController" 
bundle:nil];
    [addViewController.view setFrame:[[UIScreen mainScreen] applicationFrame]];
    self.currentTabView = addViewController ;
