Can i sort the NSDictionary on basis of key in Objective-C?

Question

Can I sort the NSDictionary on basis of key?

Answer 1

It is much simpler to use objectsForKeys:notFoundMarker: for that

NSDictionary *yourDictionary;
NSArray *sortedKeys = [yourDictionary.allKeys sortedArrayUsingDescriptors:@[[NSSortDescriptor sortDescriptorWithKey:@"self" ascending:YES]]];
// As we using same keys from dictionary, we can put any non-nil value for the notFoundMarker, because it will never used
NSArray *sortedValues = [yourDictionary objectsForKeys:sortedKeys notFoundMarker:@""];
