xcode - Parse/Swift getObjectInBackgroundWithId query not working -

-

i trying run query object in background id when run method query.getobjectinbackgroundwithid , getting error message:

"cannot invoke 'getobjectinbackgroundwithid' argument list of type (string, block: (pfobject!,nserror?) -> void"

the same thing happens when use user.signupinbackgroundwithblock i'm thinking maybe xcode updated of features while using 'block's , maybe syntax different? ideas?

here's snippet of code:

yes!!! thank you!

the new sample code getobject is:

query.getobjectinbackgroundwithid("oaq79bhv53") {         (gamescore: pfobject?, error: nserror?) -> void in         if error == nil && gamescore != nil {             println(gamescore)         } else {             println("error")         }     }

java - UML - How would you draw a try catch in a sequence diagram? -

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...
