如何在捏合和旋转手势结束后将图像设置为其原始状态？

Question

我已经添加了旋转和捏合手势，但在手势结束后，我希望我的图像处于原始状态。

这是我的函数处理旋转手势的代码

-(void)handlerotation:(UIRotationGestureRecognizer *)roatategesture
{
   if(roatategesture.state==UIGestureRecognizerStateEnded) 
   {
    roatategesture.rotation = 0.0;
    return;
   }
   self.myimage.transform = CGAffineTransformRotate(self.myimage.transform, roatategesture.rotation);
   roatategesture.rotation=0.0;
}

Answer 1

使用此：

if(roatategesture.state==UIGestureRecognizerStateEnded) {
    roatategesture.rotation = 0.0;
    self.myimage.transform = CGAffineTransformIdentity;
    return;
}
