I want to sort an NSMutableArray alphabetically.

NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:YES]; sortedArray=[anArray sortedArrayUsingDescriptors:@[sort]]; Your objects will be sorted according to the name property of those objects.
The answer is yes, the order of the elements of an array will be maintained - because an array is an ordered collection of items, just like a string is an ordered sequence of characters...
The NSMutableArray class declares the programmatic interface to objects that manage a modifiable array of objects. This class adds insertion and deletion operations to the basic array-handling behavior inherited from NSArray . NSMutableArray is “toll-free bridged” with its Core Foundation counterpart, CFMutableArray .
Creating NSArray Objects Using Array Literals In addition to the provided initializers, such as initWithObjects: , you can create an NSArray object using an array literal. In Objective-C, the compiler generates code that makes an underlying call to the init(objects:count:) method.
You can do this to sort NSMutableArray:
[yourArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
