一，代碼。

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    //2015-09-16格式
    NSDate *date = [NSDate new];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd"];
    NSString *dateStr = [dateFormatter stringFromDate:date];
    NSLog(@"---dateStr--%@",dateStr);
    
}
