Facebook iOS SDK 3.5.1 Friend Request Dialog crashed on close -

-

i have ios app uses facebook sdk. upgraded 3.2 3.5.1 in part allow me use frictionless friend requests. process works fine with:

nsmutabledictionary* params =   [nsmutabledictionary dictionarywithobjectsandkeys:nil];  [fbwebdialogs presentrequestsdialogmodallywithsession:[fbsession activesession]                                                   message:[nsstring stringwithformat:@"i posted action - give me points!"]                                                     title:@"get points friends"                                                parameters:params                                                   handler:^(fbwebdialogresult result, nsurl *resulturl, nserror *error) {                                                       if (error) {                                                           // case a: error launching dialog or sending request.                                                           nslog(@"error sending request.");                                                       } else {                                                           if (result == fbwebdialogresultdialognotcompleted) {                                                               // case b: user clicked "x" icon                                                               nslog(@"user canceled request.");                                                           } else {                                                               nslog(@"request sent.");                                                           }                                                       }}];

but add friend cache (copy / pasted facebook website):

    nsmutabledictionary* params =   [nsmutabledictionary dictionarywithobjectsandkeys:nil];        fbfrictionlessrecipientcache *friendcache = [[fbfrictionlessrecipientcache alloc] init];     [friendcache prefetchandcacheforsession:nil];      [fbwebdialogs presentrequestsdialogmodallywithsession:[fbsession activesession]                                                   message:[nsstring stringwithformat:@"i posted action - give me points!"]                                                     title:@"get points friends"                                                parameters:params                                                   handler:^(fbwebdialogresult result, nsurl *resulturl, nserror *error) {                                                       if (error) {                                                           // case a: error launching dialog or sending request.                                                           nslog(@"error sending request.");                                                       } else {                                                           if (result == fbwebdialogresultdialognotcompleted) {                                                               // case b: user clicked "x" icon                                                               nslog(@"user canceled request.");                                                           } else {                                                               nslog(@"request sent.");                                                           }                                                       }}      friendcache:friendcache];

the app load dialog crash on [fbwebdialoginternaldelegate completewithresult:url:error:] @ fbwebdialogs.m:93: when either tap x button cancel dialog or try send request.

do need add dependancies, start sessions in new way, link or else don't tell in https://developers.facebook.com/docs/tutorial/iossdk/upgrading-from-3.2-to-3.5/?

thanks.

pretty sure in case it's because you're not retaining friendcache anywhere, , gets released before fbwebdialogs tries use (such when dialog dismissed).

if move friendcache ivar or property in class instead of local variable, should work.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
