ios - SDWebImageView Cache issue when offline and with percent escaped URLs -


i using sdwebimage display images asynchronously, , cache them, them when in offline mode.

i having issue sdwebimagedownloader , uiimageview+webcache cache when using offline mode, , issue appears when dealing percent escaped urls, have special characters '{'.

in online mode works fine, in offline mode images urls containing percent escapes not loaded

[myimageview setimagewithurl:[urlimage percentescapedurl]                    completed:^(uiimage *image, nserror *error, sdimagecachetype cachetype) {                        //image here loaded in offline mode if url not need percent escapes                    }];

the same issue sdwebimagedownloader.

i tried debug sdimageview behaviour, , seems it's using ios sdk nscachedurlresponse behaviour.

i testing https://github.com/rs/sdwebimage/ ios 7.0

any 1 has got same issue? workaround?

sdwebimage has property declared in sdwebimagemanager.h:

@property (strong) nsstring *(^cachekeyfilter)(nsurl *url);

there description of property corresponding file:

/**  * cache filter block used each time sdwebimagemanager need convert url cache key. can  * used remove dynamic part of image url.  *  * following example sets filter in application delegate remove query-string  * url before use cache key:  *  * @code  [[sdwebimagemanager sharedmanager] setcachekeyfilter:^(nsurl *url) {     url = [[nsurl alloc] initwithscheme:url.scheme host:url.host path:url.path];     return [url absolutestring]; }];   * @endcode  */

i think can try changes in corresponding code.
