移动UIImage时钟指针？

Question

我正在研究用X代码创建模拟时钟，并且在解决如何全天候旋转时钟时遇到问题。我使用png文件作为时钟指针 老实说，我不确定除了外观之外如何添加时钟方面。我在Youtube上找到的每个教程重复相同的代码并且不是我需要的，加上它通常是一年前的，如果不是更老的  这是我的代码

    seconds.text = [NSString stringWithFormat:@"%i", MainInt];

    MainInt = 0;
    timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countup) userInfo:nil repeats:YES];
}


@synthesize label;

-(void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //label.text =  @"Bye";
   [self updateTime];

}
-(void)updateTime
{
    NSDateFormatter *dateFormat = [ [NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"hh:mm:ss"];
    label.text = [dateFormat stringFromDate: [NSDate date] ];

    //call updateTime after 1 second
    [self performSelector:@selector(updateTime) withObject:self afterDelay:1.0];
}
