x向右为正，y向下为正

1.y<0

 UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(40, 40, 250, 50)];

    label.backgroundColor=[UIColor clearColor];

    label.textColor=[UIColor redColor];

    label.text=@"和合谷";

    label.shadowColor=[UIColor blueColor];

    label.shadowOffset=CGSizeMake(0, -3);

运行结果为：

第二.y>0

 UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(40, 40, 250, 50)];

    label.backgroundColor=[UIColor clearColor];

    label.textColor=[UIColor redColor];

    label.text=@"和合谷";

    label.shadowColor=[UIColor blueColor];

    label.shadowOffset=CGSizeMake(0, 3);

第三、x>0

 UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(40, 40, 250, 50)];

    label.backgroundColor=[UIColor clearColor];

    label.textColor=[UIColor redColor];

    label.text=@"和合谷";

    label.shadowColor=[UIColor blueColor];

    label.shadowOffset=CGSizeMake(3, 0);

    [self.view addSubview:label];

结果：

第四、x<0

UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(40, 40, 250, 50)];

    label.backgroundColor=[UIColor clearColor];

    label.textColor=[UIColor redColor];

    label.text=@"和合谷";

    label.shadowColor=[UIColor blueColor];

    label.shadowOffset=CGSizeMake(-3, 0);
