如何在objective-C中对字符串进行排序？

#import<Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSArray *strings = @[@"apple", @"banana", @"cherry", @"date", @"fig", @"grape", @"kiwi", @"lemon", @"mango", @"nectarine", @"orange", @"pear", @"quince", @"raspberry", @"strawberry", @"tangerine", @"watermelon"];

        NSArray *sortedStrings = [strings sortedArrayUsingSelector:@selector(compare:)];

        NSLog(@"Sorted strings: %@", sortedStrings);
    }
    return 0;
}
