Question

I have a task to add a timer on my apps which is appear on exam mode page. I have done every thing but can’t convert total time into min:sec format. Please Anyone can help me.

Answer 1

You can use modulo arithmetic:

int totalSecondsRemaining = // however you obtain it
int minutesRemaining = totalSecondsRemaining / 60; // integer division, truncates fractional part
int secondsRemaining = totalSecondsRemaining % 60; // modulo division

someLabel.text = [NSString stringWithFormat:@"%02d:%02d", minutesRemaining, secondsRemaining];

(Remark: this is elementary school maths…)
