Memory leak on uiwebview alloc

Question

In my app I have a uiwebview which I used to display image file. Now the problem is I am getting a leak in this view. I have written the following code:

UIWebView *the_pWebView = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // the leak is on this line. 
the_pWebView.backgroundColor = [UIColor whiteColor];
the_pWebView.scalesPageToFit = YES;
the_pWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
the_pWebView.delegate = self;

self.m_pWebView = the_pWebView;
[self.view addSubview: self.m_pWebView];
[the_pWebView release];

In the first line of the code, where I am allocing the uiwebview, why would this be leaking even if I have released it?

Answer 1

If the m_pWebView property is retain or copy then you need to make sure you release it in your dealloc method on that class. I suspect you're not releasing it there.

Answer 2

您还应该在将 self.m_pWebView 添加到 self.view 后释放它

Answer 3

in ViewDidLoad

 [self performSelectorOnMainThread:@selector(abc) withObject:nil waitUntilDone:YES];

then make a function name is abc

   -(void) abc
    {

 UIWebView *the_pWebView = [[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; 

 the_pWebView.backgroundColor = [UIColor whiteColor];

the_pWebView.scalesPageToFit = YES;

the_pWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);

 the_pWebView.delegate = self;

 self.m_pWebView = the_pWebView;


  [self.view addSubview: self.m_pWebView];

  [the_pWebView release];

iWebView=nil;

 }
