Create an NSString with leading zeroes for minutes and seconds

Question

I need to constantly update the a playback time in a label. I am getting the time `NSTimeInterval currentProgress = self.moviePlayerController.currentPlaybackTime;` which returns a double value. But the format in which I need to display is "MM:SS" (00:00). I have tried the following code ``` NSTimeInterval currentProgress = self.moviePlayerController.currentPlaybackTime; float min = floor(currentProgress/60); float sec = round(currentProgress - min * 60); ``` When the progress time is 10 minutes and 10 seconds it displays perfectly fine, as "10:10". But the problem here is if the progress time is 1 minute and 7 seconds, it displays "1:7" in the label. My intended display is "01:07". How can I do that?

Accepted Answer

```
NSString *time = [NSString stringWithFormat:@"%02d:%02d", (int)min, (int)sec];
```

Try this. Should just work!
