iphone - 自动释放，没有池 - 只是泄漏

Question

我的主代码中有这一行:

[self performSelectorInBackground:@selector(animateMe) withObject:nil];

这是 animateMe

- (void) animateMe {

  [UIView animateWithDuration:1.0
     animations:^{
           [myView setAlpha:0.0f];

  }];

}

这些是我在终端上看到的消息

 *** __NSAutoreleaseNoPool(): Object 0x1af740 of class myClass autoreleased with no pool in place - just leaking
 *** __NSAutoreleaseNoPool(): Object 0x1af740 of class myClass autoreleased with no pool in place - just leaking

- (void) animateMe {
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
  [UIView animateWithDuration:1.0
     animations:^{
           [myView setAlpha:0.0f];

  }];
  [pool drain];
}
