All of these look more complicated than they need to be! Here is a short and sweet way to convert a time interval into hours, minutes and seconds:

<pre><code>NSTimeInterval timeInterval = 326.4;
long seconds = lroundf(timeInterval); // Since modulo operator (%) below needs int or long

int hour = seconds / 3600;
int mins = (seconds % 3600) / 60;
int secs = seconds % 60;
</code></pre>

Note when you put a float into an int, you get floor() automatically, but you can add it to the first two if if makes you feel better :-)

Forgive me for being a Stack virgin... I'm not sure how to reply to Brian Ramsay's answer...

Using round will not work for second values between 59.5 and 59.99999. The second value will be 60 during this period. Use trunc instead...

<pre><code> double progress;

 int minutes = floor(progress/60);
 int seconds = trunc(progress - minutes * 60);

If you're targeting at or above iOS 8 or OS X 10.10, this just got a lot easier. The new <code>NSDateComponentsFormatter</code> class allows you to convert a given <code>NSTimeInterval</code> from its value in seconds to a localized string to show the user. For example:

Objective-C

<pre><code>NSTimeInterval interval = 326.4;

NSDateComponentsFormatter *componentFormatter = [[NSDateComponentsFormatter alloc] init];

componentFormatter.unitsStyle = NSDateComponentsFormatterUnitsStylePositional;
componentFormatter.zeroFormattingBehavior = NSDateComponentsFormatterZeroFormattingBehaviorDropAll;

NSString *formattedString = [componentFormatter stringFromTimeInterval:interval];
NSLog(@"%@",formattedString); // 5:26
</code></pre>

Swift

<pre><code>let interval = 326.4

let componentFormatter = NSDateComponentsFormatter()

componentFormatter.unitsStyle = .Positional
componentFormatter.zeroFormattingBehavior = .DropAll

if let formattedString = componentFormatter.stringFromTimeInterval(interval) {
 print(formattedString) // 5:26
}
</code></pre>

<code>NSDateCompnentsFormatter</code> also allows for this output to be in longer forms. More info can be found in NSHipster's <a href="http://nshipster.com/nsformatter/">NSFormatter article</a>. And depending on what classes you're already working with (if not <code>NSTimeInterval</code>), it may be more convenient to pass the formatter an instance of <code>NSDateComponents</code>, or two <code>NSDate</code> objects, which can be done as well via the following methods.

Objective-C

<pre><code>NSString *formattedString = [componentFormatter stringFromDate:&lt;#(NSDate *)#&gt; toDate:&lt;#(NSDate *)#&gt;];
NSString *formattedString = [componentFormatter stringFromDateComponents:&lt;#(NSDateComponents *)#&gt;];
</code></pre>

Swift

<pre><code>if let formattedString = componentFormatter.stringFromDate(&lt;#T##startDate: NSDate##NSDate#&gt;, toDate: &lt;#T##NSDate#&gt;) {
 // ...
}

if let formattedString = componentFormatter.stringFromDateComponents(&lt;#T##components: NSDateComponents##NSDateComponents#&gt;) {
 // ...
}
</code></pre>

Since it's essentially a double...

Divide by 60.0 and extract the integral part and the fractional part.

The integral part will be the whole number of minutes.

Multiply the fractional part by 60.0 again.
