Use Sdwebimage to load different pictures but the URL of the picture is the same

The point is in the sdwebimagemanager.m file, about 176 lines

On the basis of (using sdwebimagerefreshcached), modify the SD library

if (Image && options & sdwebimagerefreshcached) {//progressive off if image already cached but forced Refreshing 
downloaderoptions &= ~sdwebimagedownloaderprogressivedownload;
//Ignore image read from Nsurlcache if image if cached but force 
refreshing downloaderoptions |= sdwebimagedownloaderignorecachedresponse;< c3/>}

Add this section of code//Remove Sdwebimagedownloaderusensurlcache flag downloaderoptions &= ~sdwebimagedownloaderusensurlcache;

if (Image && options & sdwebimagerefreshcached) {//progressive off if image already cached but forced refreshing downloaderoptions &= ~sdwebimagedownloaderprogressivedownload; Yes, that's it.//Ignore image read from Nsurlcache if image if cached and force refreshing downloaderoptions |= Sdwebimagedownlo Aderignorecachedresponse;}

if (Image && options & sdwebimagerefreshcached) {//progressive off if image already cached but forced Refreshing
downloaderoptions &= ~sdwebimagedownloaderprogressivedownload; 

Yes, that's it.//Ignore image read from Nsurlcache if image if cached and force refreshing downloaderoptions |= Sdwebimagedo 
Wnloaderignorecachedresponse; 
}

At last

if (Image && options & sdwebimagerefreshcached) {//progressive off if image already cached but forced Refreshing 
downloaderoptions &= ~sdwebimagedownloaderprogressivedownload;
//Remove Sdwebimagedownloaderusensurlcache flag 
downloaderoptions &= ~sdwebimagedownloaderusensurlcache;//Ignore Image read from Nsurlcache if image if cached but force 
refreshing downloaderoptions |= Sdwebimagedownloaderignorecach Edresponse; 
}

The second workaround is to change the "extra header" to achieveiOS development ~sdwebimage is how to do URL unchanged, update the content of the picture
