Question

我在ipad的主视图中添加了4个子视图（UIScrollView，UITableView），每个视图都有自己的数据。
在Marco视图中，我尝试每隔3秒从服务器重新加载数据以刷新我的Marco视图作为第一张照片。

当我在popoverView上删除一个时，我在ipad主视图上设置了3个Marco图标 popoverView上的图标确实删除了，但仍然在主视图上显示3个图标作为第二和第三张照片...

必须从后台删除，然后打开应用程序才能正确查看..
作为第四张照片。
任何一个人都知道什么是问题。我尝试使用[marco_scrollview setNeedsDisplay] 但它没有用..
提前谢谢..
这是我获得Marcodata的代码：

- (void)getTheMacroURLData{
    //[self.view setNeedsDisplay];
//    [marco_scrollview setNeedsDisplay];
    self.macroList = nil;
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    EnvoTouchAppDelegate *appDelegate = (EnvoTouchAppDelegate *)[[UIApplication sharedApplication] delegate];
    struct sockaddr_in Addr;
    bzero(&Addr, sizeof(Addr));
    Addr.sin_len = sizeof(Addr);
    Addr.sin_family = AF_INET;
    SCNetworkReachabilityRef target = SCNetworkReachabilityCreateWithAddress(NULL, (struct sockaddr *) &Addr);
    SCNetworkReachabilityFlags flags;
    SCNetworkReachabilityGetFlags(target, &flags);
    if (flags & kSCNetworkReachabilityFlagsIsWWAN){
        //Serial Number not save in the keychain now
        NSString *theNewURLString = [NSString stringWithFormat:eGetAllMacrosSettingURL3G,[userDefaults objectForKey:@"ecsn"],appDelegate.udid];
        NSURL *theNewURL = [NSURL URLWithString:theNewURLString];
        self.macroList = [NSMutableArray arrayWithContentsOfURL:theNewURL];
    }
    if (flags & kSCNetworkFlagsReachable){
        NSString *theNewURLString = [NSString stringWithFormat:eGetAllMacrosSettingURLWiFi,appDelegate.ipString,appDelegate.udid];
        NSURL *theNewURL = [NSURL URLWithString:theNewURLString];
        self.macroList = [NSMutableArray arrayWithContentsOfURL:theNewURL];
    }
    int k=0;
    for (int i=0; i<[self.macroList count]; i++) {
        int j=i%9;
        if (j==0) {
            k++;
        }
        UIButton *iconButton=[UIButton buttonWithType:UIButtonTypeCustom];
        NSString *picString = [[self.macroList objectAtIndex:i] valueForKey: @"pid"];
        UIImage *buttonImage = [UIImage imageNamed:picString];

        [iconButton setImage:buttonImage forState:UIControlStateNormal];
        [iconButton setTag:i];
        [iconButton addTarget:self action:@selector(exeMacro:) forControlEvents:UIControlEventTouchUpInside];  
        [iconButton setFrame:CGRectMake(30+(i%9*80), 17+((k-1)*70), 48, 48)];   
        //[self.view addSubview:iconButton];
        [marco_scrollview addSubview:iconButton];
        if ([self.macroList count] > 18) {
            [marco_scrollview setContentSize:CGSizeMake(320, 525 + (([self.macroList count]/4 - 4) * 70) )];
        }
    }
    [marco_view addSubview:marco_scrollview];
}

我尝试每3秒重新加载一次数据。我不知道为什么它不刷新Marco View ..

显示使其看起来好像是在某个地方使用tableview。如果是这样，你是否在表视图上调用reloadData方法？
