Objective c NSInvocationOperation与坏访问崩溃

我在

NSInvocationOperation

中遇到了一个大问题。当我在iPod4固件5.0.1上运行时，一切正常。但在我的iPhone4，iOS4.1上，它崩溃了。这是我的代码：

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];

在CustomAnnotation类中定义了updateAnnotation函数：

- (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;
    }

我不知道哪里错了？请帮帮我。谢谢大家

尝试在启用NSZombies的情况下运行。它至少应该给您一个提示，告诉您在解除分配对象后尝试访问哪个对象

我尝试打开NSZombies，但它只在第行显示错误访问：NSInvocationOperation*op=[[NSInvocationOperation alloc]initWithTarget:annotation selector:@selector（updateAnnotation:）object:param]；不要告诉我什么被释放了。它是在CustomAnnotation类中定义的。
