ios - Scrolling to Bottom of UITableView When Messages Load -

i'm trying figure out how scroll bottom of uitableview once messages database load it. i've tried using tableview.setcontentoffset(cgpointmake(0, cgfloat.max), animated: true) table goes having messages in nothing @ all. i've tried

var ipath = nsindexpath(forrow: messagesarray.count - 1, insection: 0) tableview.scrolltorowatindexpath(ipath, atscrollposition: uitableviewscrollposition.bottom, animated: true) 

but exc_bad_access code = 1. appreciated.

edit:

i'm putting code in viewdidappear() function right after parse finds data query.findobjectsinbackgroundwithblock(...), not sure if makes difference or not.

here's query code:

    query.findobjectsinbackgroundwithblock { (object, error) -> void in                     if (error == nil) {                         var = 0; < object!.count; i++ {                             var messageobject = messages()                              messageobject.messageid = object![i]["messageid"] as! string                              println("message id")                             println(messageobject.messageid)                              messageobject.messagetext = object![i]["message"] as! nsstring string                              println("message text")                             println(messageobject.messagetext)                              messageobject.recipientid.append(object![i]["recipientid"] as! nsstring string)                              println("recipient")                             println(messageobject.recipientid[0])                              messageobject.senderid = object![i]["senderid"] as! nsstring string                             messageobject.timestamp = object![i]["timestamp"] as! nsstring string                              println("timestamp")                             println(messageobject.timestamp)                              dispatch_async(dispatch_get_main_queue(), { () -> void in                                 self.messagesarray.append(messageobject)                             })                         }                           self.loadobjects()                         self.tableview.reloaddata()                         self.tableview.setcontentoffset(cgpointmake(0, cgfloat.max), animated: true)                     }     } 

please try one

in objective-c

 nsinteger bottomrow = [self.dataarr count] - 1; // count's array.     if (bottomrow >= 0) {         nsindexpath *indexpath = [nsindexpath indexpathforrow:bottomrow insection:0];         [self.tblview scrolltorowatindexpath:indexpath                                atscrollposition:uitableviewscrollpositiontop animated:animated];     } 

in swift

var bottomrow : nsinteger = dataarr.count-1; if (bottomrow >= 0) {              var indexpath : nsindexpath = nsindexpath(forrow: bottomrow, insection: 0)               tblview.scrolltorowatindexpath(indexpath, atscrollposition: uitableviewscrollposition.bottom, animated: true)          }
