how can i define NSTimeInterval to mm:ss format in iphone?
NSTimeInterval interval = 326.4;long min = (long)interval / 60; // divide two longs, truncateslong sec = (long)interval % 60; // remainder of long divideNSString* str = [[NSString alloc] initWithFormat:@"%02d:%02d", min, sec];The %02d format specifier gives you a 2 digit number with a leading zero.
Note: this is for positive values of interval only.
See this question.
Accepted answer by Brian Ramsay is:
Given 326.4 seconds, pseudo-code:
minutes = floor(326.4/60)seconds = round(326.4 - minutes * 60)If you print with %02d, you will get e.g. 03:08 if either number is less than 10.
