Checking if string time range is now

Question

I have an object with 2 String properties: notifyFrom and notifyTo.

They are like:

notifyFrom: 14:00

notifyTo: 18:00

and before I send the user a notification (that's part of my app) I want to check if the time is between those hours and just if it is to send the notification.

Note: Date doesn't matter here. I just want to check the times

What is the best way to do it?

Thanks!

means do you want to check that whether your time string is between `notifyfrom` and `notifyto` ?? If this is so then what about date ?? or date doesn't matter ?? — Ketan Parmar, Oct 25 '16 at 08:23

Get the `hour` component from the current date and check if the `Range` `notifyFrom...notifyTo` `contains` the value. However it becomes a bit more complicated if `To` can be lower than `From` — vadian, Oct 25 '16 at 08:34

You can write method something like,

+ (BOOL)date:(NSDate*)date isBetweenDate:(NSDate*)beginDate andDate:(NSDate*)endDate
{
if ([date compare:beginDate] == NSOrderedAscending)
    return NO;

if ([date compare:endDate] == NSOrderedDescending)
    return NO;

return YES;
}

Reference : this so post

First of all convert the input two strings to dates

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"HH:mm:ss"];

NSDate *date1 = [dateFormatter dateFromString:notifyFrom];
NSDate *date2 = [dateFormatter dateFromString:notifyTo];

NSDate *userDate = [NSDate date];

if (([userDate laterDate: date1] == userDate) && ([userDate laterDate: date2] == date2)){
}
