- (void)viewDidLoad {    [super viewDidLoad];    // Do any additional setup after loading the view, typically from a nib. NSString* cityPlistPath = [[NSBundle mainBundle] pathForResource:@"cities" ofType:@"plist"]; //按照拼写排序,spell是英文拼写 NSSortDescriptor *bySpell = [NSSortDescriptor sortDescriptorWithKey:@"spell" ascending:YES]; NSArray *cities = [[NSArray arrayWithContentsOfFile:cityPlistPath] sortedArrayUsingDescriptors:@[bySpell]]; NSLog(@"--cities--%@",cities); }
