ios - 您将如何用 MBProgressHud 加载 View 替换 PFQueryTableViewController 的库存加载 View ？

Question

Parse.com 为其 PFQueryTVC 提供了库存加载 View 。但是，我想自定义它并实现 MBProgressHUD 加载 View 的样式。有没有人完成过这个或类似的事情，并且有什么技巧可以分享？

Answer 1

我会尝试找到一个作为加载 View 的 subview ，然后将其删除并在其位置放置一个 MBProgressHUD。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.
                }
            }
        }
    }
