iOS Format String into minutes and seconds

Question

I am receiving a string from the YouTube JSONC api, but the duration is coming as a full number i.e 2321 instead of 23:21 or 2 instead of 0:02. How would I go about fixing t

Answer 1

Assuming the duration value is really the duration in seconds, then you can calculate the number of minutes and seconds and then format those into a string.

int duration = ... // some duration from the JSON
int minutes = duration / 60;
int seconds = duration % 60;

NSString *time = [NSString stringWithFormat:@"%d:%02d", minutes, seconds];
