Compare two time values in ios? [duplicate]

Answer 1

First you need to convert your time string to NSDate => Converting time string to Date format iOS.

Then use following code

NSDate *timer1 =...
NSDate *timer2 =...

       NSComparisonResult result = [timer1 compare:timer2];
       if(result == NSOrderedDescending)
       {
          // time 1 is greater then time 2 
       }
       else if(result == NSOrderedAscending)
       {
           // time 2 is greater then time 1 
       }
       else
       {
          //time 1 is equal to time 2
       }
