iphone - OSStatus error 1718449215

Question

I have created an iPhone application to record our voice. When I try to record, I am getting error message in following statement.

recorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];

Error Domain=NSOSStatusErrorDomain Code=1718449215 "Operation could not be completed. (OSStatus error 1718449215.)"

If I tried to record in .caf file, it is working fine. If I tried with .m4a, I am getting this error message.

Please help me to resolve it.

Thanks.

1718449215 is the decimal representation of the four character code for the kAudioFormatUnsupportedDataFormatError error.

In general you can use something like this to get more information from the errors you receive:

NSError *error = [NSError errorWithDomain:NSOSStatusErrorDomain
                          code:my_error_code
                          userInfo:nil];
NSLog(@"Error: %@", [error description]);
