ios - EXC_BAD_ACCESS with viewWillTransitionToSize and Xcode 6.3 -

-

this code used work in our today extension, exc_bad_access using xcode 6.3. new problem?

override func viewwilltransitiontosize(size: cgsize, withtransitioncoordinator coordinator: uiviewcontrollertransitioncoordinator) {     coordinator.animatealongsidetransition({ context in         self.tableview.frame = cgrectmake(0, 0, size.width, size.height)         }, completion: nil) }

someone mentioned me think apple bug. here's workaround (or solution):

override func viewwilltransitiontosize(size: cgsize, withtransitioncoordinator coordinator: uiviewcontrollertransitioncoordinator) {     super.viewwilltransitiontosize(size, withtransitioncoordinator: coordinator)      if let safecoordinator = coordinator uiviewcontrollertransitioncoordinator?     {         println("coordinator != nil")         safecoordinator.animatealongsidetransition({ context in             self.tableview.frame = cgrectmake(0, 0, size.width, size.height)             }, completion: nil)      }     else     {         println("coordinator == nil")     } }

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...
