ios - Chromecast 警告 loadMedia 自动播放已弃用

Question

在我的 playSelectedItemRemotely 方法中，我收到一条警告消息:

 - (void)playSelectedItemRemotely {
    GCKCastSession* castSession = [GCKCastContext sharedInstance].sessionManager.currentCastSession;
    if (castSession) {
        // WARNING ON LINE BELOW
        [castSession.remoteMediaClient loadMedia:[self buildMediaInformation] autoplay:YES]; 
    } else {
        NSLog(@"No cast session!");
    }
}

说:

'loadMedia:autoplay:' is deprecated: Use loadMedia:withOptions:

如何解决这个问题？

Answer 1

就像警告消息所说，您可以使用 loadMedia:withOptions 方法，如下所示:

- (void)playSelectedItemRemotely {
    GCKCastSession* castSession = [GCKCastContext sharedInstance].sessionManager.currentCastSession;
    if (castSession) {
        GCKMediaLoadOptions *options = [GCKMediaLoadOptions init];
        [castSession.remoteMediaClient loadMedia:[self buildMediaInformation] withOptions:options];
    } else {
        BILog(@"No cast session!");
    }
}

以下是您可以使用的选项:

• (BOOL) autoplay Whether playback should start immediately.

The default value is YES.

• (NSTimeInterval) playPosition The initial playback position.

The default value is kGCKInvalidTimeInterval, which indicates a default playback position.

• (float) playbackRate The playback rate.

The default value is 1.

• (NSArray*) activeTrackIDs An array of integers specifying the active tracks.

The default value is nil.

• (id) customData Custom application-specific data to pass along with the request.

Must either be an object that can be serialized to JSON using NSJSONSerialization, or nil.

• (NSString*) credentials

The user credentials for the media item being loaded.

• (NSString*) credentialsType

The type of user credentials specified in GCKMediaLoadOptions::credentials.
