show record timer while making video

Question

I had implemented the concept of AVCaptureSession for recording video.

-(void)startRecordingWithOrientation:(AVCaptureVideoOrientation)videoOrientation 
{

    AVCaptureConnection *videoConnection = [AVCamUtilities   
                                           connectionWithMediaType:AVMediaTypeVideo  
                                           fromConnections:[[self movieFileOutput] connections]];
    if ([videoConnection isVideoOrientationSupported])
        [videoConnection setVideoOrientation:videoOrientation];

    [[self movieFileOutput] startRecordingToOutputFileURL:[self outputFileURL]  
    recordingDelegate:self];
 } 

It is recording the video properly but the recording timer in not there on the screen. Anyone has an idea that how to show timer while making video.

Thanks in advance.

Answer 1

I use add a UILabel to the view where is presented the video while is recording and I use this code to show the record time

@property (weak, nonatomic) IBOutlet UILabel *labelTime;

@property(nonatomic, strong) NSTimer *timer;
@property(nonatomic) int timeSec;
@property(nonatomic) int timeMin;

//Method to start recording

- (void)startRecord {
    self.timeMin = 0;
    self.timeSec = 0;

    //String format 00:00
    NSString* timeNow = [NSString stringWithFormat:@"%02d:%02d", self.timeMin, self.timeSec];
    //Display on your label
    //[timeLabel setStringValue:timeNow];
    self.labelTime.text= timeNow;

    self.timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(timerTick:) userInfo:nil repeats:YES];
    [[NSRunLoop currentRunLoop] addTimer:self.timer forMode:NSDefaultRunLoopMode];

    //Start recording
    [movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self];

}


//Event called every time the NSTimer ticks.
- (void)timerTick:(NSTimer *)timer {
    self.timeSec++;
    if (self.timeSec == 60)
    {
        self.timeSec = 0;
        self.timeMin++;
    }
    //String format 00:00
    NSString* timeNow = [NSString stringWithFormat:@"%02d:%02d", self.timeMin, self.timeSec];
    //Display on your label
    self.labelTime.text= timeNow;
}
