Why is this leak happening?
I do not like this idea very much to ask a question which is very specific and there is the possibility of helping many other people, but for a few hours of scratching my head Afterwards, I have not left any option.
The leaking tool reports that the following code leak occurs: / P>
- (zero) such as abscondualoffholes {UIGraphicsBeginImageContextWithOptions (CGSizeMake (50.0f, 50.0f), Yes, 0.0 F); CGContextRef Reference = UIGraphicsGetCurrentContext (); CGLayerRef * Size Layer = Malloc (3 * size (* Size Layer)); (Int i = 0; I Specifically, it reports that the CGLayerCreateWithContext function is a problem but this object is leaking and not the objects, which it gives:
I doubt that my problem is due to the fundamental lack of understanding of memory management / dynamic allocation and anyone should know me 'this' finger because I There is no leak in the following code Is:
- (void) No Lex {UIGraphicsBeginImageContextWithOptions (CGSizeMake (50.0f, 50.0f), yes, 0.0f); CGContextRef Reference = UIGraphicsGetCurrentContext (); CGLayerRef Shape Layer = CGLayerCreateWithContext (Reference, CGSizeMake (5.0f, 5.0f), NULL); CGLayerRelease (shapeLayer); UIGraphicsEndImageContext (); }
Please note that this is clearly a problem in its simple copy-deferable state. I am using dynamic memory allocation because the size of the array in my actual code is not known at compile time.
I can not tell you why the Instruments reports that CGContext Objects are leaking, and not CGLayer , but
shape layer [i] = CGLear crat vethacontax (reference, CGS immec (5.0 F, 5.0F) ), Nouel); Definitely should be issued with
CGLARLIZ (size layer [ii]); and not
free (shape layer [i]); is not CGLayerCreateWithContext malloc , so calling for that code free can cause memory corruption .
