Ios MBProgressHUD和UITableView

我在填充TableView时显示了一个HUD，但它似乎显示在TableView后面（TableView分隔符破坏了HUD）

以下是TableViewController中的代码：

- (void)viewDidLoad {
[super viewDidLoad];

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = @"Loading";

// Populate the table
[self getTableData];

self.tableView.rowHeight = 90;
}

---

它仅在tableView中执行此操作。

这里的问题是，在加载视图时添加HUD，这可能是在显示tableView之前，因此创建tableView并显示为覆盖HUD。将该代码移动到ViewDidDisplay中，您的问题就会消失：

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeText;
    hud.labelText = @"Loading";
}

如果要在

viewdiload

中实现，请使用

self.navigationController.view

而不是

self.view

，包括：

#import <QuartzCore/QuartzCore.h>

zPosition值越高，显示优先级越高

Even in ViewDidLoad also we can handle it like this::   
  - (void)viewDidLoad {
 [super viewDidLoad];     
   MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
  hud.labelText = @"Loading..";
  dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
   [self contactsFromAddressBook];
    dispatch_async(dispatch_get_main_queue(), ^{
        [MBProgressHUD hideHUDForView:self.view animated:YES];
       [self.tableView reloadData];

     });
  });

---

}

这应该是公认的答案！而

MBProgressHUD

的演示也使用了这个

  - (void)viewDidLoad {
 [super viewDidLoad];     
   MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
  hud.labelText = @"Loading..";
  dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{
   [self contactsFromAddressBook];
    dispatch_async(dispatch_get_main_queue(), ^{
        [MBProgressHUD hideHUDForView:self.view animated:YES];
       [self.tableView reloadData];

     });
  });
