ios - Retrieving a cropped photo from the Facebook Graph API -

-

i have developed part of ios application involves using facebook's graph api accesses user's photos, , allows user crop image square desired zoom. images must squares. there way use graph api given rect parameter returns url of desired photo cropped rect? have done research , seems there isn't, hoping set of eyes on that.

assuming there isn't, sounds better idea:

  1. uploading cropped photo own servers future access.

or

  1. use own sql database store rect of cropping , url of photo (hosted facebook), , load full facebook photo , crop how want.

1 offers efficiency when loading data internet, means storing more data in own servers (this expensive in future)

2 means use less space on own servers, means entire photo forced loaded, parts won't used.

i'm leaning towards 2, don't deal web/database work hoping advice. thanks.

facebook transformations of pictures. not want might interesting take look:

https://developers.facebook.com/docs/graph-api/reference/photo https://developers.facebook.com/docs/graph-api/reference/platform-image-source/

@cbroe has point not store urls obtained facebook directly. try , save cropped picture on servers.

html - jQuery UI Sortable - Remove placeholder after item is dropped -

-
i'm trying nested sortable , i'm kind'a succeeding, there's 1 small little inconvenience bugs me. i want placeholder disappear after i've dropped dragged item (on mouseup) , can't quite figure out how it. i want because when sort downwards, deletion of placeholder affects parent's height, in turn creates small bug, check jsfiddle here. html <div class="container"> <h1>menu</h1> <ul class="list-group striped nest"> <li class="list-group-item">home <ul class="list-group striped nest"></ul></li> <li class="list-group-item">about <ul class="list-group striped nest"></ul></li> <li class="list-group-item"> services <ul class="list-group striped nest"> <li class="list-group-item">design <ul class=
