I want to display the size of an audio file in a UITableView
. I recorded the audio with:
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayAndRecord error: nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
NSDictionary *recordSettings = [[NSDictionary alloc] initWithObjectsAndKeys:
[NSNumber numberWithFloat: 44100.0], AVSampleRateKey,
[NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
[NSNumber numberWithInt: 1], AVNumberOfChannelsKey,
[NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil];
I saved the file in the Documents folder, and I'm displaying the name in a UITableView
cell.
How do I display the size of the audio file as well?
Try this
NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError];
NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
long long fileSize = [fileSizeNumber longLongValue];
Note that the fileSize won't necessarily fit in an integer (especially a signed one) although you could certainly drop to a long for iOS as you'll never exceed that in reality. The example uses long long as in my code I have to be compatible with systems with much larger storage available.
