Question

我正在使用自定义相机点击多个图像。现在点击几张图片后我收到内存警告，我的应用程序没有崩溃。任何人都可以帮我解决这个问题。我的代码如下所示

CImage = (UIImage *)[info objectForKey:UIImagePickerControllerOriginalImage];


[arrimages addObject: CImage];





if (aPicker.sourceType == UIImagePickerControllerSourceTypeCamera) {
    custvw.cameraButton.enabled = YES;


}
else
{


    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {

        [self.popoverController dismissPopoverAnimated:true];
        NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

        [self dismissViewControllerAnimated:YES completion:nil];

        if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
        {
            if (picker.sourceType==UIImagePickerControllerSourceTypePhotoLibrary)
            {

                [self.picker dismissViewControllerAnimated:YES completion:nil];

            }

            else
            {





            }


        }
        else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie])
        {
        }
    }

            else
    {
        [self.picker dismissViewControllerAnimated:YES completion:nil];


    }


    }

通过将所选图像添加到阵列中来保存所选图像并不是一个好主意。这些图像通常非常耗费内存，很容易填满内存。

[arrimages addObject: CImage];

可能的解决方案：

缩放图片

从UIImagePickerControllerDelegate检索图像后缩放图像 - imagePickerController：didFinishPickingMediaWithInfo：还有助于减少内存占用。

将图像保存到磁盘

不要将图像保存在内存中，而是将它们保存到磁盘中，并在需要时从磁盘中获取。
