ios:泄漏警告不明确
我有以下两种方法:
-(void)playSound {
NSString* filePath = [self getBasePath]; // <-- warnings appear when this is called
}
当
-(NSString*) getBasePath {
if( debug ) NSLog(@">>> Entering %s <<<", __PRETTY_FUNCTION__);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
if( debug ) NSLog(@">>> Leaving %s <<<", __PRETTY_FUNCTION__);
return documentsDir;
}
调用playsound 时,调用方法getBasePath。但随后我在控制台上收到以下警告:
2011-08-06 00:26:56.298 Alarm[82648:5d03] *** __NSAutoreleaseNoPool(): Object 0x4e350e0 of class __NSArrayM autoreleased with no pool in place - just leaking

这是什么意思?
I've got the following two methods:
-(void)playSound {
NSString* filePath = [self getBasePath]; // <-- warnings appear when this is called
}
and
-(NSString*) getBasePath {
if( debug ) NSLog(@">>> Entering %s <<<", __PRETTY_FUNCTION__);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
if( debug ) NSLog(@">>> Leaving %s <<<", __PRETTY_FUNCTION__);
return documentsDir;
}
When calling playsound the methode getBasePath is called. But then I get the following warning on the console:
2011-08-06 00:26:56.298 Alarm[82648:5d03] *** __NSAutoreleaseNoPool(): Object 0x4e350e0 of class __NSArrayM autoreleased with no pool in place - just leaking

What does that mean?

可能您不是在主线程上执行此方法。如果这样做,您必须创建一个 NSAutoreleasePool。
Probably you are executing this method not on the main thread. If you do, you have to create a NSAutoreleasePool.
