How to send data from Iphone to Apple Watch in OS2 in Objective-C
(1 answer)
Closed 7 years ago.
I am having an issue with getting an audio file that I record on my iPhone to play out of my Watch speakers.
Here is the code I have for sending from iPhone to Watch.
- (void)sendLiveAudioRecordingToWatch
{
NSError *error;
NSFileManager *files = [NSFileManager defaultManager];
NSString *docs = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *record = [docs stringByAppendingPathComponent: #"LiveAudio.m4a"];
NSURL *URL = [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier: #"group.myCompany.myApp"];
NSURL *outputURL = [URL URLByAppendingPathComponent: #"PhoneToWatch.mp4"];
NSString *path = [NSString stringWithFormat: #"%#", outputURL];
NSLog(#"%#", [NSURL fileURLWithPath: path]);
[files removeItemAtPath: [outputURL path] error: &error];
BOOL fileExists = [files isReadableFileAtPath: record];
if (fileExists)
{
NSLog(#"Live Audio Recording Saved!");
[files copyItemAtPath: record toPath: [outputURL path] error: &error];
if (!error)
{
NSLog(#"Temporary Recording Copied To Group");
BOOL deleteRecord = [files removeItemAtPath: record error: &error];
if (deleteRecord)
{
NSLog(#"Temporary Recording Removed");
if ([WCSession isSupported])
{
WCSession *session = [WCSession defaultSession];
NSLog(#"WCSession isSupported");
[session setDelegate: self];
[session activateSession];
if ([session isReachable])
{
NSLog(#"File Is Being Transferred");
[[WCSession defaultSession] transferFile: outputURL metadata: nil];
}
else
{
NSLog(#"Watch Not Reachable");
}
}
}
else
{
NSLog(#"Failed To Delete Temorary File");
}
}
else
{
NSLog(#"Error Copying Live Audio To Group");
}
}
else
{
NSLog(#"Error Locating Temporary Audio Location");
}
}
Here is the code I have for receiving on Watch from iPhone.
- (void)session: (WCSession *)session didReceiveFile: (WCSessionFile *)file
{
WKAudioFileAsset *asset = [WKAudioFileAsset assetWithURL: [file fileURL]];
WKAudioFilePlayerItem *playerItem = [WKAudioFilePlayerItem playerItemWithAsset: asset];
WKAudioFilePlayer *player = [WKAudioFilePlayer playerWithPlayerItem: playerItem];
[player play];
}
iOS 9.2 watchOS 2.0
Has anyone experienced this, or was able to get this working?

Answer 1

I got this working. WKAudioFilePlayer is used for playing through a bluetooth device, not the speakers of the Apple Watch. In WatchOS 2.0 and higher, you can use:
[self presentMediaPlayerControllerWithURL:url options:options completion:^(BOOL didPlayToEnd, NSTimeInterval endTime, NSError * __nullable error){}];
