我正在尝试保存 UIImage，但它给了我一个错误。UIImage 是从 UIImagePickerController 中挑选出来的，然后通过NSData生成它并调用writeToFile:这个NSData对象来保存。这样做时，我会得到一个错误。同样的方法可以完美地存储其他图像。我可以毫无问题地存储的图像从网站检索为字节数组，然后转换为 UIImage，然后保存。似乎该问题特定于来自UIImagePickerController.

谁能告诉我如何解决这个问题？

似乎UIImagePickerController保存的图像很好，但我仍然收到导致应用程序崩溃的错误：

5 月 1 日 10:38:05 Simon-BS-iPhone Diims[619]：ImageIO：JPEG Corrupt JPEG 数据：数据段过早结束

这是用于保存图像的代码：

+ (void)storeImage:(UIImage *)image name:(NSString *)name
{
    NSString *pathForCache = [self pathForCache];
    NSData *imageData = [NSData dataWithData:UIImageJPEGRepresentation(image, 1.0f)];
    NSString *jpegPath = [pathForCache stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.jpeg", name]];

    NSError *error;
    if ([imageData writeToFile:jpegPath options:NSDataWritingAtomic error:&error] == NO)
    {
        DLog(@"Could not save image: %@", jpegPath);
        DLog(@"%@", error);
    }
}

选择图像时这样调用：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
{
    // Close controller
    [picker dismissModalViewControllerAnimated:YES];

    // Save image
    self.selectedDevice.image = image;
    [CDeviceManager localUpdateDevice:self.selectedDevice delegate:self];
}

如果可行，请尝试按如下方式更改代码：-

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
 {
       // Save image self.selectedDevice.image = image;
       [CDeviceManager localUpdateDevice:self.selectedDevice delegate:self];

       // Close controller [picker dismissModalViewControllerAnimated:YES];
       //dismiss after saving the image
  }
