[xmlvm-users] about org_xmlvm_iphone_AVAudioPlayer initialization

[Panayotis K. <pan...@pa...>]

in the initialization of  "org_xmlvm_iphone_AVAudioPlayer.m", there is  
this code:

return [[[AVAudioPlayer alloc] initWithContentsOfURL: url error:  
&(outError->error_org_xmlvm_iphone_NSError)] retain];

Why there is a need for a second retain there (the first is the alloc  
itself) ?
