90MB手机端VLM实战：轻量化多模态模型部署指南视觉语言模型（VLM）作为多模态AI的核心范式，正从云端服务器加速向终端设备下沉。其技术本质是视觉编码器与语言解码器通过跨模态对齐实现图文联合表征，关键挑战在于算力受限、内存带宽紧张与功耗敏感三大约束。轻量化并非简单压缩，而是围绕参数量、计算图结构与精度配置展开的系统性工程——包括视觉主干替换（如MobileViTv2）、语言模型蒸馏（TinyLLaMA）、融合机制重构（GMU门控单元）及分层混合量化（INT4/INT8/FP16协同）。该技术路径显著提升端侧推理效率与隐私安全性，广泛适用于无障碍辅助、工业阅读详情

在IOS上，如果用ALAssertLibrary创建相册，如果该相册被删除过了，则再次创建，会创建成功，但是group为nil

[self addAssetsGroupAlbumWithName:albumName

resultBlock:^(ALAssetsGroup *group) {

//get the photo's instance

[weakSelf assetForURL: assetURL

resultBlock:^(ALAsset *asset) {

//add photo to the newly created album

[group addAsset: asset];

//call the completion block

completionBlock(nil);

} failureBlock: completionBlock];

在苹果的官方文档中，有一段说明，大概意思就是IOS8之后使用了新的库PHPhotoLibrary代替ALAssetsLibrary。

导入库Photo.framework,此时注意修改后面的选项为option，否则你的应用就必须支持IOS8以及以上了。

IOS8 创建相册

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{

[PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:albumName];

} completionHandler:^(BOOL success, NSError *error) {

} failureBlock:completionBlock];

}

}];

//下面是修改ALAssetsLibrary+CustomPhotoAlbum 的代码，兼容IOS8，在外调用依旧不变

-(void)addAssetURL:(NSURL*)assetURL toAlbum:(NSString*)albumName withCompletionBlock:(SaveImageCompletion)completionBlock

{

__block BOOL albumWasFound = NO;

//search all photo albums in the library

[self enumerateGroupsWithTypes:ALAssetsGroupAlbum

usingBlock:^(ALAssetsGroup *group, BOOL *stop) {

//compare the names of the albums

if ([albumName compare: [group valueForProperty:ALAssetsGroupPropertyName]]==NSOrderedSame) {

//target album is found

albumWasFound = YES;

//get a hold of the photo's asset instance

[self assetForURL: assetURL

resultBlock:^(ALAsset *asset) {

//add photo to the target album

[group addAsset: asset];

//run the completion block

completionBlock(nil);

} failureBlock: completionBlock];

//album was found, bail out of the method

return;

}

if (group==nil && albumWasFound==NO) {

//photo albums are over, target album does not exist, thus create it

(在 iOS 8.0 后, 使用the Photos framework 代替 the Assets Library framework ,

The Photos framework 提供更特色和更好的表现在使用 photo library 工作的时候)

iOS 8.0 之后, 相册新增了 Recently Deleted (最近删除) 这个功能, 导致我们在相册里边手动删除 "Rd"相册是并没有完全删除, 导致创建相册虽然成功, 但却为 nil ,

因为创建的相册还是处于 Recently Deleted 的状态;

if (IS_IOS_8) {

__weak ALAssetsLibrary* weakSelf = self;

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{

[PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:albumName];

} completionHandler:^(BOOL success, NSError *error) {

if (success) {

[weakSelf enumerateGroupsWithTypes:ALAssetsGroupAlbum usingBlock:^(ALAssetsGroup *group, BOOL *stop) {

if ([albumName compare: [group valueForProperty:ALAssetsGroupPropertyName]]==NSOrderedSame) {

[weakSelf assetForURL: assetURL

resultBlock:^(ALAsset *asset) {

//add photo to the target album

[group addAsset: asset];

//run the completion block

[self performSelectorOnMainThread:@selector(saveCompletionSuccess:) withObject:completionBlock waitUntilDone:YES];

} failureBlock: completionBlock];

}

} failureBlock:completionBlock];

}

}];

}else{

__weak ALAssetsLibrary* weakSelf = self;

//create new assets album

[self addAssetsGroupAlbumWithName:albumName

resultBlock:^(ALAssetsGroup *group) {

//get the photo's instance

[weakSelf assetForURL: assetURL

resultBlock:^(ALAsset *asset) {

//add photo to the newly created album

[group addAsset: asset];

//call the completion block

completionBlock(nil);

} failureBlock: completionBlock];

//should be the last iteration anyway, but just in case

return;

}

} failureBlock: completionBlock];

}
