objective c - Save a photo to custom album in iOS 8 -


i need little bit of in here, have method saves uiimage camera roll without problems in ios 8. method following

[[phphotolibrary sharedphotolibrary] performchanges:^{     [phassetchangerequest creationrequestforassetfromimage:image]; }completionhandler:^(bool success, nserror *error) {     if(success){         nslog(@"worked");     }else{         nslog(@"error: %@", error);      } }];

i need adapt code, image instead of saving uiimage camera roll, saves custom album named "myalbum"

i'm using photos.framework

you first need check album exists fetch request, , either add image album or create album , add image.

#import <photos/photos.h>  - (void)addimagetocameraroll:(uiimage *)image {     nsstring *albumname = @"myalbum";      void (^saveblock)(phassetcollection *assetcollection) = ^void(phassetcollection *assetcollection) {         [[phphotolibrary sharedphotolibrary] performchanges:^{             phassetchangerequest *assetchangerequest = [phassetchangerequest creationrequestforassetfromimage:image];             phassetcollectionchangerequest *assetcollectionchangerequest = [phassetcollectionchangerequest changerequestforassetcollection:assetcollection];             [assetcollectionchangerequest addassets:@[[assetchangerequest placeholderforcreatedasset]]];          } completionhandler:^(bool success, nserror *error) {             if (!success) {                 nslog(@"error creating asset: %@", error);             }         }];     };      phfetchoptions *fetchoptions = [[phfetchoptions alloc] init];     fetchoptions.predicate = [nspredicate predicatewithformat:@"localizedtitle = %@", albumname];     phfetchresult *fetchresult = [phassetcollection fetchassetcollectionswithtype:phassetcollectiontypealbum subtype:phassetcollectionsubtypeany options:fetchoptions];     if (fetchresult.count > 0) {         saveblock(fetchresult.firstobject);     } else {         __block phobjectplaceholder *albumplaceholder;         [[phphotolibrary sharedphotolibrary] performchanges:^{             phassetcollectionchangerequest *changerequest = [phassetcollectionchangerequest creationrequestforassetcollectionwithtitle:albumname];             albumplaceholder = changerequest.placeholderforcreatedassetcollection;          } completionhandler:^(bool success, nserror *error) {             if (success) {                 phfetchresult *fetchresult = [phassetcollection fetchassetcollectionswithlocalidentifiers:@[albumplaceholder.localidentifier] options:nil];                 if (fetchresult.count > 0) {                     saveblock(fetchresult.firstobject);                 }             } else {                 nslog(@"error creating album: %@", error);             }         }];     } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
