uigesturerecognizer - Swift invert UIRotationGestureRecognizer for subviews -


i want invert rotation uirotationgesturerecognizer specific subviews. rotation occurs in 90 degree phases (so cgfloat.pi / 2 )

func localhandlerotategesture (localrotategesture: uirotationgesturerecognizer) {     if localrotategesture.state == .ended {         if localrotategesture.rotation > 0.0005{             localrotategesture.view?.transform = (localrotategesture.view?.transform)!.rotated(by: cgfloat.pi / 2) }     localrotategesture.rotation = 0  }

works fine. access subviews , try invert movement

    var thiscell = localrotategesture.view as! custommessagecell     thiscell.cellbuttonsstackview.transform = (localrotategesture.view?.transform.inverted())!.rotated(by: cgfloat.pi / 2)

the subviews rotate first attempt, , after doesn't! going on?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
