Iphone 写入文件时出现ImageIO错误

我试图保存UIImage，但它给了我一个错误。UIImage从UIImagePickerController中拾取，然后通过从中提取

NSData

并在此

NSData

对象上调用

WriteFile:

来保存。 这样做时，我将得到一个错误。同样的方法可以完美地存储其他图像。我可以毫无问题地将从网站检索到的图像存储为字节数组，然后将其转换为UIImage并保存。 似乎该问题特定于来自

UIImagePickerController

的图像

有人能告诉我怎么解决这个问题吗

来自

UIImagePickerController

的图像似乎保存得很好，但我仍然收到此错误，导致应用程序崩溃：

5月1日10:38:05西蒙BS iPhone Diims[619]：图像IO:JPEG 损坏的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);
    }
}

当选择图像时，它被称为：

- (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];
}

如果代码有效，请尝试按以下方式更改代码：-

- (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
  }

---

如果代码有效，请尝试按如下方式更改代码：-（无效）imagePickerController:（UIImagePickerController*）picker didFinishPickingImage:（UIImage*）图像编辑信息：（NSDictionary*）编辑信息{//Save image self.selectedDevice.image=image；[CDDeviceManager localUpdateDevice:self.selectedDevice委托：self]；//关闭控制器[picker dismissModalViewControllerAnimated:YES]；}//保存似乎起作用的图像后关闭。多谢各位。你能回答一下你的评论吗？嗨，西蒙斯，我已经发布了与答案相同的帖子。
