加载光库图像时发生错误:错误:FigCreateCGImageFromJPEG返回-12910. 423114字节.我们将退回到软件解码 [英] Error occuring when loading photolibrary images : ERROR: FigCreateCGImageFromJPEG returned -12910. 423114 bytes. We will fall back to software decode

问题描述

我正在与一个应用程序一起使用，该应用程序正在从照相馆库加载图像.

I'm working with an application in which I'm loading images from photolibrary.

我正在使用以下代码将图像绑定到imageView.

I'm using the following code for binding the image to imageView.

-(void)loadImage:(UIImageView *)imgView FileName:(NSString *)fileName
{
   typedef void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *asset);
   typedef void (^ALAssetsLibraryAccessFailureBlock)(NSError *error);    

   ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
   {
     ALAssetRepresentation *rep = [myasset defaultRepresentation];
     CGImageRef iref = [rep fullResolutionImage];
     UIImage *lImage;
     if (iref)
     {
        lImage = [UIImage imageWithCGImage:iref scale:[rep scale] orientation:(UIImageOrientation)[rep orientation]];   
     }
     else
     {
        lImage = [UIImage imageNamed:@"Nofile.png"];
     }
     dispatch_async(dispatch_get_main_queue(), ^{
         [imgView setImage:lImage];
     });
   };

   ALAssetsLibraryAccessFailureBlock failureblock  = ^(NSError *myerror)
   {
       UIImage *images = [UIImage imageNamed:@"Nofile.png"];
        dispatch_async(dispatch_get_main_queue(), ^{
             [imgView setImage:images];
     });        
   };                   


    NSURL *asseturl = [NSURL URLWithString:fileName];

    ALAssetsLibrary *asset = [[ALAssetsLibrary alloc] init];
    [asset assetForURL:asseturl
           resultBlock:resultblock
          failureBlock:failureblock];
}

但是，当我尝试运行它时，就会出现错误，并且应用程序有时会崩溃. 控制台上显示的错误是:

But when I tried to run it, an error is coming and the application is crashing sometimes. The error printed on console is:

** *错误:FigCreateCGImageFromJPEG返回-12910. 423114字节.我们将退回到软件解码. 收到内存警告. 我的照片库包含高分辨率图像，其大小在10-30 MB之间.

** * ERROR: FigCreateCGImageFromJPEG returned -12910. 423114 bytes. We will fall back to software decode. Received memory warning. My photo library contains high resolution images and their size between 10-30 MB.

推荐答案

最后，我解决了该问题. 我认为问题在于获取完整分辨率的图像.

Finally I fixed the issue. I think the issue is with fetching the full resolution image.

而不是:

CGImageRef iref = [rep fullResolutionImage];

我用过:

CGImageRef iref = [myasset aspectRatioThumbnail];

一切正常.控制台中没有错误，没有崩溃，但是图像的质量/分辨率降低了.

And everything worked fine. No error in console, no crash, but quality/resolution of the image is reduced.
