I have some trivial questions regarding sorting a simple array of strings.
I used to use this code:
NSSortDescriptor *sd = [[NSSortDescriptor alloc] initWithKey: nil
ascending: YES];//TODO: raus
[imagefiles_ sortUsingDescriptors: @[sd] ];
where imagefiles_ is an NSMutableArray* .
Now, in the developer doc
(
https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Collections/Articles/Arrays.html#//apple_ref/doc/uid/20000132-SW5)
I saw a different method. Following that, I was thinking of sorting my array
like this:
NSArray * sorted_images = [imagefiles_ sortedArrayUsingSelector:
@selector(localizedStandardCompare:) ];
imagefiles_ = [NSMutableArray arrayWithArray: sorted_images];
First of all, what are the advantages/disadvantages of either method?
Second, I was wondering if I could write the second method like this:
imagefiles_ = [imagefiles_ sortedArrayUsingSelector:
@selector(localizedStandardCompare:) ];
Thanks a lot in advance.
