How to sort a NSArray alphabetically?

Question

How can I sort an array filled with [UIFont familyNames] into alphabetical order?

Answer 1

The simplest approach is, to provide a sort selector (Apple's documentation for details)

Objective-C

sortedArray = [anArray sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

Swift

let descriptor: NSSortDescriptor = NSSortDescriptor(key: "YourKey", ascending: true, selector: "localizedCaseInsensitiveCompare:")
let sortedResults: NSArray = temparray.sortedArrayUsingDescriptors([descriptor])

---

Apple provides several selectors for alphabetic sorting:

• compare:
• caseInsensitiveCompare:
• localizedCompare:
• localizedCaseInsensitiveCompare:
• localizedStandardCompare:

Swift

var students = ["Kofi", "Abena", "Peter", "Kweku", "Akosua"]
students.sort()
print(students)
// Prints "["Abena", "Akosua", "Kofi", "Kweku", "Peter"]"
