how can add elements array textview 1 second delay?

language- swift (still relatively new programming)

i think need

class viewcontroller: uiviewcontroller {      @iboutlet weak var textview: uitextview!      var array = ["string1", "string2", "string3"]     var = 0     var str: string = ""     var timer = nstimer()      func testfunc() {         str += "\(array[i])\n"         textview.text = str         if == count(array) - 1 {             timer.invalidate()         }         += 1     }      override func viewdidload() {         super.viewdidload()          timer = nstimer.scheduledtimerwithtimeinterval(1.0, target: self, selector: selector("testfunc"), userinfo: nil, repeats: true)     }      override func didreceivememorywarning() {         super.didreceivememorywarning()         // dispose of resources can recreated.     } }

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
