你如何用MBProgressHud加载视图替换PFQueryTableViewController的库存加载视图？

Question

Parse.com的view库存加载PFQueryTVC。但是，我想自定义它并实现MBProgressHUD's加载视图的样式。有没有人完成这个或类似的东西，并有任何提示分享？

Answer 1

我会尝试找到一个加载视图的子视图，然后删除它并将MBProgressHUD放在其位置。代码：

for (UIView *subview in self.view.subviews)
    {
        if ([subview class] == NSClassFromString(@"PFLoadingView"))
        {
            // find the loading label and loading activity indicator inside the PFLoadingView subviews
            for (UIView *loadingViewSubview in subview.subviews) {
                if ([loadingViewSubview isKindOfClass:[UILabel class]])
                {
                    UILabel *label = (UILabel *)loadingViewSubview;
                    //code to remove and put in new view.
                }

                if ([loadingViewSubview isKindOfClass:[UIActivityIndicatorView class]])
                {
                    UIActivityIndicatorView *activityIndicatorView = (UIActivityIndicatorView *)loadingViewSubview;
                    //code to remove and put in new view.
                }
            }
        }
    }
