ios - UIVIew size use device size in interface builder and no constraint -


i have following scene in interface builder.

enter image description here

and following code in viewdidload function of controller

print(string.init(format:"basecircleview width %f height %f", basecircleview.bounds.size.width, basecircleview.bounds.size.height)) print(string.init(format:"userdrawingview width %f height %f", userdrawingview.bounds.size.width, userdrawingview.bounds.size.height)) print(string.init(format:"view width %f height %f", self.view.bounds.size.width, self.view.bounds.size.height))

when launch app (on iphone6 simulator "view : iphone se" selected in storyboard), have following in console :

basecircleview width 320.000000 height 504.000000

userdrawingview width 320.000000 height 504.000000

view width 375.000000 height 667.000000

i not understand why 2 views infer sizes device "view : iphone se" selected in storyboard , not superview.

can me figure what's wrong ?

you should test constraints @ viewdidlayoutsubviews.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
