ios - Multiple UIWindows and touch events -

i have created second window , add on top of default :

[topwindow makekeyandvisible]; topwindow.hidden = no; 

it works top window block access of application's default window. want know if it's possible if there no element ( button exemple ) in top window @ given place of screen, can access elements of default window @ below.

i hope understandable. sorry english. advance help.

i have created second window , add on top

so, think usual expectation there's 1 window per screen in ios app. the docs seem imply this:

every app has 1 window displays app’s user interface on ios-based device display. if external display connected device, app can create second window present content on display well.

it's possible ios assumes there's 1 window per screen, , hit-testing process considers 1 window, key window. since you're making second window key window, i'd suggest making first window key after create second window , see if changes things. wouldn't surprising if first window receives touches , second doesn't. if find that's case, might subclass uiwindow, override -hittest:withevent: pass event other windows if no hit view found, , use subclass both windows.

otherwise, if can't work, consider going single window , using different views instead. question similar make view appear in every view, inside app, , my suggestion there create own container view controller might you.
