Question

I have a MBProgressHUD that I allocate as follows:

 self.progressHUD_ = [[[MBProgressHUD alloc] initWithView:self.view] autorelease];

if I call removeFromSuperview then would I have to call progressHUD release again? Also if I declare a property with something like this:

NSString * title_;

@property (nonatomic, retain) NSString * title_;

then it is guaranteed that in my dealloc I should have a release on title right?

Answer 1

No, you don’t have to release it again. Views retain their subviews and release them again automatically when you call removeFromSuperview. As long as the view has been autoreleased when you attach it to the view, it will be released when it is removed from the view.

I didn’t quite understand your second question, but yes, you have to release any properties of type “retain” or “copy” in your dealloc statement. You have to write those release statements manually, they aren’t added automatically (unless you are using ARC of course, which I strongly recommend).
