Add Minutes | Hours | Days to NSDate

NSDate *date = [NSDate date];
NSTimeInterval timeInterval = YOUR_DOUBLE_VALUE;
NSLog(@"Time Interval : %.2f", timeInterval);
date = [date dateByAddingTimeInterval:timeInterval];
NSLog(@"Date : %@",date);

For Minutes : +/-(no.of mins * 60);
For Hours : +/-(no. of hrs * 60 * 60);
For days : +/-(no. of days * 60 * 60 * 24);
+ sign for add.
- sign for subtract.
Both will work.

NSTimeInterval accepts double value.
