通过使用此代码
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:selectedVideoUrl];
CMTime duration = playerItem.duration;
float seconds = CMTimeGetSeconds(duration);
NSLog(@"duration: %.2f", seconds);错误
Undefined symbols for architecture armv7:

在CoreMedia.framework中定义了CMTime。将该框架添加到您的项目中。
看看苹果的CMTime reference
