訪問崩潰的NSInvocationOperation

我遇到了一個大問題NSInvocationOperation。當我在我的iPod 4上運行固件5.0.1時，沒關係。但在我的iPhone 4，iOS 4.1上，它墜毀了。這是我的代碼：訪問崩潰的NSInvocationOperation

CustomAnnotation *annotation = [[[ModelManager defaultModelManager] getAnnotationDictionaryInMemory] objectForKey:joltId]; 

if (annotation == nil) 
    annotation = [[[ModelManager defaultModelManager] getAnnotationDictionaryInMemory] annotationWithInstagramId:eID]; 

if (annotation == nil) 
    continue; 
//THIS ONE CRASH ON IPHONE 4 OS 4.1 
NSDictionary *param = [[NSDictionary alloc] initWithObjectsAndKeys: @"aKey", @"aValue", nil]; 

NSInvocationOperation *op = [[NSInvocationOperation alloc] initWithTarget:annotation selector:@selector(updateAnnotation:) object:param]; 

[_queue addOperation:op]; 
[op autorelease];

updateAnnotation函數，CustomAnnotation類中定義：

- (void)updateAnnotation:(id)sender { 
//NSLog(@"UPDATE ANNOTATION ID: %@", self.annoID); 
NSDictionary *senderDic = (NSDictionary *)sender; 
UzooltAppDelegate* appDelegate = (UzooltAppDelegate*) [UIApplication sharedApplication].delegate; 

if ([senderDic objectForKey:@"nb_rejolt"] != nil) { 
    NSInteger new_nb_rejolts = [[senderDic objectForKey:@"nb_rejolt"] intValue]; 
    //if (new_nb_rejolts != rejolts) { 
     //NSLog(@"update nb rejolts: %d", new_nb_rejolts); 

     if (self.rejolts != new_nb_rejolts) { 
      self.rejolts = new_nb_rejolts; 
      //if (self.isGrouped) 
      // [self.masterAnnotation.annotationView performSelectorOnMainThread:@selector(updateAnnotationViewWithRejolts:) withObject:[NSString stringWithFormat:@"%d", rejolts] waitUntilDone:NO]; 
      //else 

      if ([senderDic objectForKey:@"rejolt_fbid"] != nil) { 
       NSString *fbRejoltsString = [senderDic objectForKey:@"rejolt_fbid"]; 
       self.fbRejolts = [[fbRejoltsString componentsSeparatedByString:@","] mutableCopy]; 
       [self.fbRejolts removeLastObject]; 
       [self updateNumberOfRejoltsFromFBFrds]; 
      } 

      [self.annotationView performSelectorOnMainThread:@selector(updateAnnotationViewWithRejolts:) withObject:[NSString stringWithFormat:@"%d", rejolts] waitUntilDone:NO]; 
     } 

     if (self.isGrouped) { 
      if (self.masterAnnotation.isShowingRadius == NO && appDelegate.uMainViewController.isInGroup == NO && (new_nb_rejolts > self.masterAnnotation.rejolts || (new_nb_rejolts == self.masterAnnotation.rejolts && self.getAge < self.masterAnnotation.getAge))) { 
       [self.masterAnnotation removeFromGroupedAnnotations:self]; 
       self.annotationView.hidden = NO; 
       [self.annotationView performSelectorOnMainThread:@selector(showWithAlpha:) withObject:[NSNumber numberWithFloat:annotationAlpha] waitUntilDone:NO]; 
       [[NSNotificationCenter defaultCenter] postNotificationName:@"need_group_annotations" object:nil]; 
      } 
     } 
    //} 
} 

if ([senderDic objectForKey:@"lifetime"] != nil) { 
    float new_lifetime = [[senderDic objectForKey:@"lifetime"] floatValue]*3600; 
    //NSLog(@"new lifetime: %.f", new_lifetime); 
    if (new_lifetime != lifetime) { 
     //NSLog(@"update lifetime"); 
     self.lifetime = new_lifetime; 
    } 
} 

[self updateViewAlpha]; 

if ([senderDic objectForKey:@"radius"] != nil) { 
    float new_radius = [[senderDic objectForKey:@"radius"] floatValue]; 
    if (new_radius != radius) { 
     //NSLog(@"update lifetime"); 
     self.radius = new_radius; 
    } 
} 

/* 
if ([appDelegate.uMainViewController isMaximumZoomIn]) 
    [[self annotationView] performSelectorOnMainThread:@selector(setGroupNumberIndicatorVisible:) withObject:[NSNumber numberWithBool:YES] waitUntilDone:NO]; 
else 
    [[self annotationView] performSelectorOnMainThread:@selector(setGroupNumberIndicatorVisible:) withObject:[NSNumber numberWithBool:NO] waitUntilDone:NO]; 
*/ 

if (isSelected == YES && isShowingRadius == NO) { 
    //NSLog(@"update details"); 
    [self performSelectorOnMainThread:@selector(updateDetailsView) withObject:nil waitUntilDone:NO]; 

    UzooltAppDelegate* appDelegate = (UzooltAppDelegate*) [UIApplication sharedApplication].delegate; 
    if (isGrouped == YES && appDelegate.uMainViewController.isInGroup) { 
     NSLog(@"grouped jolt rejolted"); 
     [self performSelectorOnMainThread:@selector(updateInGroupAnnotationView) withObject:nil waitUntilDone:NO]; 
    } 
}

}

我不知道哪裏錯了？請幫幫我。謝謝大家！

嘗試在啓用NSZombies的情況下運行。它應該至少給你一個提示，說明它在釋放後要訪問什麼對象。

NSZombies enabled, debug information

我試圖接通NSZombies但它只能顯示線BAD ACCESS： NSInvocationOperation * OP = [[NSInvocationOperation的alloc] initWithTarget：註釋選擇器：@selector（updateAnnotation :)對象：PARAM] ; 不要告訴我什麼已經釋放。 – 2012-07-11 02:45:14

定義updateAnnotation方法在哪裏？ – jjathman 2012-07-11 03:00:25

它在CustomAnnotation類中定義。 – 2012-07-11 03:52:49
