CMTime秒輸出

Question

這看起來很荒謬，但是我怎樣才能將CMTime的秒數輸出到Objective-C的控制檯？我只需要按時間分割的值，然後以某種方式在控制檯中看到它。

Answer 1

NSLog(@"seconds = %f", CMTimeGetSeconds(cmTime)); 

Answer 2

簡單：

 NSLog(@"%lld", time.value/time.timescale); 

Answer 3

如果你想在hh:mm:ss格式轉換，那麼你可以使用這個

NSUInteger durationSeconds = (long)CMTimeGetSeconds(audioDuration); 
NSUInteger hours = floor(dTotalSeconds/3600); 
NSUInteger minutes = floor(durationSeconds % 3600/60); 
NSUInteger seconds = floor(durationSeconds % 3600 % 60); 
NSString *time = [NSString stringWithFormat:@"%02ld:%02ld:%02ld", hours, minutes, seconds]; 
NSLog(@"Time|%@", time); 

Answer 4

CMTime currentTime = audioPlayer.currentItem.currentTime; 
float videoDurationSeconds = CMTimeGetSeconds(currentTime);
