Capturing 'self' strongly in this block is likely to lead to a retain cycle

[cri1682]

I'm getting this warning if i call "self" inside the completion block or the error block, something like

     conn.errorBlock = ^(NSError *error) {

        if (error.code!=4 ) {
            UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"error" message:@"" delegate:self cancelButtonTitle:@"close" otherButtonTitles:nil];
            [alert show];
        }

    };

The warning is attached on "delegate:self". The warning disappear if i declare a weak reference to "self"

__weak MyDataProcessor *dp = self;

Maybe you can prevent those warnings by an intervention in the library?

Unfortunately, I don't think I can do anything.

Capturing a weak self as you do is, according to Apple, a "best practice":
