我必须在手指触摸上循环旋转视图...我的意思是像拨打旧手机号码......触摸应该只在角落.....任何人都可以帮助我...我试过它很多......但没有成功

您需要UIRotationGestureRecognize在视图上定义要旋转的内容,然后添加选择器方法并像这样实现它.
将此添加到您的viewDidLoad方法
UIRotationGestureRecognizer *rotate = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotation:)];
[myUIViewObject addGestureRecognizer:rotate];
[rotate release];

然后实现该方法.
- (void) rotation:(UIRotationGestureRecognize *) sender
{
CGAffineTransform myTransform = CGAffineTransformMakeRotation(sender.rotation);
sender.view.transform = myTransform;
}

PS.myUIViewObject可以是UIView您要旋转的任何对象.
