momery leak

[uranpro]

when you set selfReference
self.selfReference = self;
release method will never calls

[TimCinel]

There's a line
self.selfReference = nil
which is called when the ActionSheetPicker is dismissed.

If there are other references to self, then dealloc is called and no leaks occur.

Are you actually getting a leak? If so, how? I'm not able to produce a leak, and I get no analyser warnings.

One easy way to test is to place a breakpoint inside the dealloc method.

sorry, i mean dealloc method will never calls.
UIView *v = [[[UIView alloc] init] autorelease];
[[[ActionSheetDatePicker alloc] initWithTarget:nil
successAction:nil
cancelAction:nil
origin:v] release];

In your example, the ActionSheetTatePicker will deallocate after you call showActionSheetPicker and it is dismissed.

The selfReference is released and set to nil when the ActionSheetPicker is dismissed.

If the ActionSheetPicker is never dismissed (nor presented) then indeed, it won't be released. To avoid this situation, don't create one unless you intend on presenting it.

[TimCinel]

UIView *v = [[[UIView alloc] init] autorelease]; ActionSheetDatePicker *datePicker = [[[ActionSheetDatePicker alloc] initWithTarget:nil successAction:nil cancelAction:nil origin:v]; [datePicker showActionSheetPicker]; [datePicker release];

In this case, the ActionSheetPicker will release soon after being dismissed. Set a breakpoint on the dealloc method for verification.

I know.
You need to move line
self.selfReference = self;
to showInView: method

PS: In my example i do not call showAcionSheetPicker, because i want to show you memory leak
