i looking general advice , maybe example code of trying accomplish if knows of ios swift project. either: a) make background, of blue view, gray , show percent of blue area. or b) overlay gray area on top of blue view , keep making gray area bigger. what trying simulate battery power , show battery. i've considered using progress bar , doing option a, blue area not solid color. image. i've tried using image progress bar, image needs keep dimensions. (ex: if progress shows 20% needs show 20% of image or "blue area", if use image progress bar shrinks image , still shows 100% of instead of 20% need show). you can write custom self-drawing uiview behave in way describe. in other words, tell uiview percentage, , redraws blue on left , gray on right. can draw darker gray stroke outline shown in drawings. accomplished in code.

i cannot fund if there way limit number of unprocessed futures in scala. example in following code: import executioncontext.implicits.global (i <- 1 n) { val f = future { //some work bunch of object creation } } if n big, throw oom. there way limit number of unprocessed futures ether queue-like wait or exception? so, simplest answer can create executioncontext blocks or throttles execution of new tasks beyond limit. see this blog post . more fleshed out example of blocking java executorservice , here an example .
