NSArray与componentsSeparatedByString内存泄漏

我有这个功能的内存泄漏问题。我认为用componentsSeparatedByString创建一个NSArray是autorelease，但仪器似乎表明在NSArray aPair泄漏。为什么它会在那里显示泄漏，而不是以同样的方式创建其他NSArrays？NSArray与componentsSeparatedByString内存泄漏

-(void) checkRequest: (NSString *)request view:(UIViewController *)theView webView:(UIWebView *)wView 
{ 
    //NSLog(@"JSResponder - checkRequest()"); 

    NSString *aRequest = [NSString stringWithString:request]; 

    NSArray *urlArray = [aRequest componentsSeparatedByString:@"?"]; 

    if([urlArray count] > 1) 
    { 
     NSString *paramsString = [urlArray lastObject]; 
     NSString *cmd = @""; 

     NSArray *urlParamsArray = [paramsString componentsSeparatedByString:@"&"]; 
     int numCommands = [urlParamsArray count]; 

     NSMutableDictionary *paramsWithNames = [[NSMutableDictionary alloc ]      initWithCapacity:numCommands]; 

     for (NSString *elementPair in urlParamsArray) 
     { 
      NSArray *aPair = [elementPair componentsSeparatedByString:@"="]; 

      NSString *aKey = [aPair objectAtIndex:0]; 
      NSString *aParam = [aPair objectAtIndex:1]; 

      if([aKey compare:@"_command"] == NSOrderedSame) 
      { 
       cmd = aParam; 
      } 
      else 
      { 
       [paramsWithNames setValue: aParam forKey:aKey]; 
      } 
     } 

     [self executeCommand: cmd withParams: paramsWithNames view:theView webView:wView]; 

     [paramsWithNames release]; 
    } 
}

这个函数被调用由以下：

- (void)pullJSEvent:(NSTimer*)theTimer 
{ 
    NSLog(@"MainView - pullJSEvent()"); 

    NSString *jsCall = [NSString stringWithString:@"if(typeof checkOBJCEvents == 'function'){checkOBJCEvents();}"]; 

    NSString *jsAnswer = [[webView stringByEvaluatingJavaScriptFromString:jsCall] retain]; 

    if([jsAnswer compare:@"none"] != NSOrderedSame) 
    { 
     //NSLog(@"   answer => %@", jsAnswer); 
     [jsResponder checkRequest:jsAnswer view:(UIViewController *)self webView:self.webView]; 
    } 
    [jsAnswer release]; 
}
