如何使用ReplayKit的类RPBroadcastActivityViewController？

Question

我想呈现RPBroadcastActivityViewController，但是失败了。示例代码只显示黑色视图。

- (IBAction)displayServiceViewController:(id)sender {
    RPBroadcastActivityViewController *rpBroadcastActivityViewController = [[RPBroadcastActivityViewController alloc] init];
    [self presentViewController:rpBroadcastActivityViewController animated:YES completion:nil];

}

我希望它具有以下效果：

Answer 1

- (IBAction)displayServiceViewController:(id)sender {
    [RPBroadcastActivityViewController loadBroadcastActivityViewControllerWithHandler:^(RPBroadcastActivityViewController * _Nullable broadcastActivityViewController, NSError * _Nullable error) {
        broadcastActivityViewController.delegate = self;
        [self presentViewController:broadcastActivityViewController animated:YES completion:nil];
    }];

}
