1 Setting up a picture

Contains a variety of features 1,sd_setimagewithurl get network picture 2,placeholderimage placeholder picture 3,progress  Download Progress   Usage:  nslog (@ "Download progress:%f", ( Double) receivedsize / expectedsize); 4, *image *error *imageurl, respectively, after the return of the picture, error and 5, sdimagecachetype cachetype  is an enumeration type, where the picture is stored in memory, disk, or no 6,sdwebimageoptions  enumeration type        Usage: sdwebimageoptions options = sdwebimageretryfailed | sdwebimagelowpriority     SDWebImageRetryFailed  download failed repeat download          common     SDWebImageLowPriority  Pause downloads When UI interacts     common      sdwebimagecachememoryonly  only save pictures in memory     SDWebImageProgressiveDownload  You can download refresh picture      SDWebImageRefreshCached  Refresh cache from top to bottom like a browser      sdwebimagehighpriority   High priority     SDWebImageDelayPlaceholder  no load for bitmap          &nbsP;   [cell.imageview sd_setimagewithurl: (nsurl *)                          Placeholderimage: (uiimage *)                                   options: (sdwebimageoptions)                        progress:^ (NSInteger receivedSize,  nsinteger expectedsize)  {        < #code #>                               } completed:^ (UIImage *image,                                             nserror  *error,                                  sdimagecachetype cachetype,                                              nsurl *imageurl)  {                 < #code #>     }];

2 Memory Processing

Because sdwebimgae belong to the entire project, not to a controller, so do not didreceivememorywarning in the controller to deal with memory problems, and add Applicationdidreceivememorywarning method in APPDELEGATE.M

-(void) applicationdidreceivememorywarning: (uiapplication *) application{sdwebimagemanager *MRG = [SDWebImageManager    Sharedmanager];    1, cancel the down operation [MRG Cancelall]; 2, clear the memory cache [Mrg.imagecache clearmemory];}

3 Other Features1, set periodic cleanup cache time

Set 100 days, default is 7 days [sdwebimagemanager sharedmanager].imagecache.maxcacheage = 100 * 24 * 60 * 60

2, set the maximum cache capacity

No default value, unit is unclear [sdwebimagemanager sharedmanager].imagecache.maxcachesize =;
