iOS 关于sdwebimage

在SDImageCache文件补充一个方法,删除给到的URL组意外的缓存.

在一个项目中,有很多缓存图片,有些特定的图片不想清楚,然而我们不可能找到像删除的图片进行删除.所以反过来写了这个方法

-(void)removeImageCacheInAdditionToTheFavoritesWithURLs:(NSArray*)URLs{

if(URLs.count==0) {

[selfclearDisk];

return;

}

NSArray*files = [[NSFileManagerdefaultManager]subpathsOfDirectoryAtPath:self.diskCachePatherror:nil];

NSMutableArray*mutFiles = [NSMutableArrayarray];

NSMutableArray*deleteFiles = [NSMutableArrayarray];

for(NSString*fileStrinfiles) {

[mutFilesaddObject:[NSStringstringWithFormat:@"%@/%@",self.diskCachePath,fileStr]];

[deleteFilesaddObject:[NSStringstringWithFormat:@"%@/%@",self.diskCachePath,fileStr]];

}

for(NSString*urlStrinURLs) {

NSString*fileName = [selfdefaultCachePathForKey:urlStr];

if([mutFilescontainsObject:fileName]) {

[deleteFilesremoveObject:fileName];

}

}

for(NSString*deleteFileNameindeleteFiles) {

[_fileManagerremoveItemAtPath:deleteFileNameerror:nil];

}

}
