Question

を警告私は、次の2つのメソッドを持っています。しかし、コンソールで次の警告が表示されます。

2011-08-06 00:26:56.298 Alarm[82648:5d03] *** __NSAutoreleaseNoPool(): Object 0x4e350e0 of class __NSArrayM autoreleased with no pool in place - just leaking

これはどういう意味ですか？

おそらく、あなたはメインスレッドではなくこのメソッドを実行しています。そうしたら、NSAutoreleasePoolを作成する必要があります。

-(void)playSound { 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    int index = rand() % [soundFilenames count]; 
    NSString* filePath = [self getBasePath]; 
    [pool drain]; 
}
