How to compare current and manual NSDate

Question

there is a function where option NSDate is specified putting up manually. How can I prevent execution of the function with the parameter of time, less than the current time? I have tried this

if ([currentDate timeIntervalSinceDate: myTime] < 0)

but unfortunately sometimes it doesn't work Thanks in advance.

Answer 1

Another option is to convert both the date to timeIntervals using timeIntervalSince1970

int interval1 = [date1 timeIntervalSince1970];
int interval2 = [date2 timeIntervalSince1970];

if(interval1 > interval2) //etc...

Answer 2

It sounds like you want to compare the current date with your custom date. More specifically, if the current date takes place after myTime, then the condition should be true.

if ([[NSDate date] compare: myTime] == NSOrderedDescending) {
    NSLog(@"Current date is later than myTime");        
}

To the opposite, you would check the comparison against NSOrderedAscending .
