Convert NSTimeInterval to NSString in iPhone?

Question

How to covert the NSTimeInterval to NSString? I have

NSTimeInterval  today = [[NSDate date] timeIntervalSince1970]; 

I have to give "today" as input as NSString.

Answer 1

NSTimeInterval is just a double type so you can convert it to string using +stringWithFormat: method

NSTimeInterval  today = [[NSDate date] timeIntervalSince1970]; NSString *intervalString = [NSString stringWithFormat:@"%f", today]; 

Answer 2

-(NSString*)formattedDuration:(NSTimeInterval)interval{     NSDateComponentsFormatter *formatter = [[NSDateComponentsFormatter alloc] init];     formatter.allowedUnits = NSCalendarUnitHour | NSCalendarUnitMinute;     formatter.zeroFormattingBehavior = NSDateComponentsFormatterZeroFormattingBehaviorPad;     NSString *string = [formatter stringFromTimeInterval:interval];     NSLog(@"%@", string);     // output: 0:20:34     return string; }
