使用UIImagePickerControllerOriginalImage从UIImagePickerController获取图像时获取内存警告 [英] Getting memory warning while using UIImagePickerControllerOriginalImage to get image from UIImagePickerController

问题描述

我正在使用UIImagePickerController从相机获取图像。
刚捕获图像后，使用UIImagePickerControllerOriginalImage获取内存警告。
我在iOS上使用iphone 4s。

I am using UIImagePickerController for getting image from camera. Just after I capture image and get it by using UIImagePickerControllerOriginalImage getting memory warning. I am using iphone 4s with iOS.

代码在这里

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

    [self dismissViewControllerAnimated:YES completion:nil];
    UIImage* originalImage = [info objectForKey:UIImagePickerControllerOriginalImage];

//Getting memory warning after this line
    NSData *data =UIImageJPEGRepresentation(originalImage, 0.1);


}

推荐答案

<我试图用很多方法解决这些问题，但没有取得成功。
最后我改变了我的方法并使用AVCaptureSession从iPhone相机拍照
以下是Apple提供的示例代码

I have tried to solve these problem with many ways but didn't get success. Finally I have changed my approach and used AVCaptureSession to take picture from iPhone camera Here is the sample code provided by Apple

一切都很好现在没有内存泄漏，性能得到改善，捕获过程很快。

All is fine now no memory leaks, performance improved, capturing processes is fast.
