ios - How to run a segue on itself OR another viewController -

-

i have main tableviewcontroller. when user tap on cell in tableview, if condition statement true, show main tableviewcontroller again(but show data on screen), , if condition false, show viewcontroller. in prepareforsegue method have this:

if  segue.identifier == "identifier1" {     let destination = segue.destinationviewcontroller as? mainviewcontroller //     destination!.x = // x variable in view controller } else if segue.identifier == "identifier2" {     let destination = segue.destinationviewcontroller as? viewcontroller2     destination!.y = }

also, run segue after tap on cells in tableview added this:

override func tableview(tableview: uitableview, didselectrowatindexpath indexpath: nsindexpath) {     tableview.deselectrowatindexpath(indexpath, animated: true)      if condition true {         self.performseguewithidentifier("identifier1", sender: self)     }     else{         self.performseguewithidentifier("identifier2", sender: self)     } }

storyboard segue needs identifier... can have 1 value! identifier1 or identifier2 want set identifier programmatically. how should set identifier in storyboard segue? there way this? thanks!

the destination view controller set segue. since have 2 different destinations, need 2 different segues in storyboard.

the trick wire segues viewcontroller icon @ top of tableviewcontroller each of destination view controllers. click on resulting segue arrows , set identifiers in attributes inspector.

wire segue in storyboard

then can call them performseguewithidentifier have done in code.

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
