Date and time wise Sort nsmutablearray

Question

Hello everyone,

i have one problem when i sort the NSMutablearray using date and time wise.

Does anyone have idea how can i sorted array date and time wise

Thanks in advance

Answer 1

The NSArray/NSMutableArray classes contain a method...

- (void)sortUsingSelector:(SEL)comparator

Which you can call passing in the following selector...

@selector(compare:)

This uses the NSDate classes compare method to perform the sorting. An alternative would be to create a NSSortDescriptor object and pass it to the NSMutableArray's sortUsingDescriptors method.
