Question

Convert Seconds Integer To HH:MM, iPhone

Answer 1

+7 A:

I was looking for the same thing that you are looking but couldn't find one. So I wrote one -

- (NSString *)timeFormatted:(int)totalSeconds
{

    int seconds = totalSeconds % 60; 
    int minutes = (totalSeconds / 60) % 60; 
    int hours = totalSeconds / 3600; 

    return [NSString stringWithFormat:@"%02d:%02d:%02d",hours, minutes, seconds]; 
}

Thanks for your answer, it looks like what I need, but can't seem to use it without errors. I am convinced the error is on my side. If you don't mind helping me further:My value is a float and it is in seconds. I have it displaying in a label when a button is pressed. Where would your code go, and how would I make my label display the value in the HH:MM format? Many thanks,Stu

Sorted, thanks for your help. Your answer and http://stackoverflow.com/questions/1259028/convert-nsnumber-double-value-into-timeanswer by Pholker were the reason I could do this! Thanks again

by far, the cleanest approach i've seen (+1)

Great stuff -- made this a class method and rolled it into a category on NSString. Agree with bitcruncher, very clean.

+1 A:

Take a look at a similar question I asked a while ago which also covers the aspect of memory and efficiency.
