Question

i faced a lot of problem while comparing two NSDate with different format though i am new to this.

-what should be the best approach to this problem?

1.I tried to convert this two dates in into one format and then go for comparison
or Should i first Know the format of this two date then go for comparison

Answer 1

NSDate does not know any thing about it’s format. Internally the date is stored without any format or region.

To compare date you can use the compare: method.

if([someDate compare:ortherDate] == NSOrderedDescending ){
   // someDate later then otherDate;
}
