difference between [self.view release] and [view release]?

What is the di开发者_运维问答fference between

difference between [self.view release] and [view release].

I get a memory leak error in [self.view release]

[view release] is calling NSObject's - (void)release method directly on an instance variable named view.

[self.view release] is calling - (UIView *)view (I'm assuming view is of type UIView) on self and then calling - (void)release on the returned object.

There shouldn't be any practical difference. However, since one reason for using properties is to eliminate the need for explicit memory management, [self.view release] would be a strange thing to do. If it's a property, let the property accessors retain and release the object as necessary.

It's hard to see why you'd get a real leak from [self.view release]. Leaks come from failing to properly release an object -- I don't think you can create a leak by releasing something. It may be that accessing the object through a property prevents the static analyzer from connecting the dots from +alloc to -release.
