我在iOS 3.1.3 iPhone上测试我的iPhone应用程序.我使用以下方法选择/捕获图像UIImagePickerController:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setDelegate:self];
[self.navigationController presentModalViewController:imagePicker animated:YES];
[imagePicker release];



- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
    imageView.image = self.image;
    [self.navigationController dismissModalViewControllerAnimated:YES];
    submitButton.enabled = YES;
}

然后我在某个时候使用ASI类将它发送到我的Web服务器:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://example.com/myscript.php"]];
[request setDelegate:self];
[request setStringEncoding:NSUTF8StringEncoding];
[request setShouldContinueWhenAppEntersBackground:YES];
//other post keys/values
[request setFile:UIImageJPEGRepresentation(self.image, 100.0f) withFileName:[NSString stringWithFormat:@"%d.jpg", [[NSDate date] timeIntervalSinceNow]] andContentType:@"image/jpg" forKey:@"imageFile"];
[request startAsynchronous];

问题:当我用iphone拍照同时保持它的风景时,图像会上传到服务器并按照你的预期进行查看.当拍摄手机拍照时,图像会被上传并在旋转90度时被观看.

我的应用程序设置为仅在纵向模式下工作(颠倒和常规).

如何在上传后使图像始终显示正确的方向？

UIImageView中显示的图像看起来是正确的(在拍照后直接显示),但在服务器上查看则另有说明.

我正试图UIImageView在Swift中旋转180度的旋转

    UIView.animateWithDuration(1.0, animations: { () -> Void in
        self.arrowImageView.transform = CGAffineTransformMakeRotation(CGFloat(180 * M_PI))
    }) { (succeed) -> Void in

    }

但根本没有动画.我想使用animateWithDuration,因为我想在某些时候使用它CGAffineTransformMakeIdentity

使用UIView动画有效.

    UIView.beginAnimations(nil, context: nil)
    UIView.setAnimationDuration(1)
    UIView.setAnimationCurve(UIViewAnimationCurve.EaseIn)
    let radians = CGFloat(180 * M_PI / 180)
    arrowImageView.transform = CGAffineTransformMakeRotation(radians)
    UIView.commitAnimations()

我们如何在图像视图中旋转图像并在图像上应用手势,并将该图像以与图像相同的状态保存到服务器

- (IBAction)imageMove:(id)sender {
    static int numRot = 0;

    myimage.transform = CGAffineTransformMakeRotation(M_PI_2 * numRot);
    ++numRot;
}

从这段代码我能够将我的图像视图旋转90度
