Why am I getting an error?

Question

The following line of code compiles with the following warning:

Code:

[[[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error] play];

Warning:

/Users/moshe/Development/iPhone/Apps/Live/iDecide/iDecideViewController.m:29:0 /Users/moshe/Development/iPhone/Apps/Live/iDecide/iDecideViewController.m:29: warning: multiple methods named '-play' found

What's going on here?

Hi

(completely new answer)

The init method is returning type id so you are going to get that message as there are multiple methods with that signature within the Cocoa frameworks

Do it in two steps (init then play) and it should vanish.

NSError *error = NULL;
AVAudioPlayer *myplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
if(!error) { [myplayer play]; }
