在iphone menuitem中保留内存泄漏

如何解决这种情况下的内存泄漏：

NSArray *keyboard = [[[NSDictionary alloc] initWithContentsOfFile:menuPath] objectForKey:@"Menu"];
[self setMenuItems:keyboard];
[keyboard release];

setMenuItems在头文件中定义

@property (nonatomic,retain) NSArray *menuItems;

在dealoc方法中

- (void)dealloc
{
self.menuItems = nil;
[super dealloc];
}

NSArray *keyboard = [[[NSDictionary alloc] initWithContentsOfFile:menuPath] objectForKey:@"Menu"];
self.menuItems = keyboard; 
[keyboard release]; 

- (void)dealloc
{
    [menuItems release], menuItems = nil;
}

在你的dealloc方法中

- (void)dealloc
{
self.menuItems = nil;
[super dealloc];
}

NSArray *keyboard = [[[NSDictionary alloc] initWithContentsOfFile:menuPath] objectForKey:@"Menu"];
self.menuItems = keyboard; 
[keyboard release]; 

- (void)dealloc
{
    [menuItems release], menuItems = nil;
}
