Can I sort the NSDictionary
on basis of key?
Solution
You can sort the keys and then create an NSMutableArray
by iterating over them.
NSArray *sortedKeys = [[dict allKeys] sortedArrayUsingSelector: @selector(compare:)];
NSMutableArray *sortedValues = [NSMutableArray array];
for (NSString *key in sortedKeys)
[sortedValues addObject: [dict objectForKey: key]];
Solution
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:@""];
