Way to fix "release is not available"

Question

I'm having trouble with release, as I read is because I'm using Xcode 4.2. I tried the option: "Convert to Objective-C ARC" but it still fails:

Xcode found 6 issues that prevent conversion from proceeding. Fix all ARC readiness issues and try again.
receivedData = [[NSMutableData data] retain];
ARC forbids explicit message send of 'retain'

and:

[receivedData release];
"release is unavailable"

You would just use:

receivedData = [NSMutableData data];
// or
receivedData = [[NSMutableData alloc] init];

because the reference count operation under ARC is automatic.

perfect! what about the [receivedData release]; "release is unavailable"? – user1256477 May 23 '12 at 06:58

With ARC, you need no more retain, release and autorelease. – Oleg Trakhman May 23 '12 at 07:17
