Iphone 旋转UIImageView后更改缩放UIImageView

在我的图片中使用了新的比例，然后我应用了旋转，然后比例图像变为旧的比例

-(void)rotate:(UIRotationGestureRecognizer *)rotationRecognizer{
    double rotation;
    rotation=rotationRecognizer.rotation;
    ((UIImageView*)[rotationRecognizer view]).transform = CGAffineTransformMakeRotation(rotation);

    self.photoParent = [self.pictures objectAtIndex:0];

    self.photoParent.rotation =[NSNumber numberWithDouble:rotation];

    NSLog(@"rotation%@",self.photoParent);
}

看看我的答案

应用“Make..”变换将删除以前应用的任何变换。您需要使用累积形式，

cGraffineTransformRotate
