I'm trying to load a UIView and then right away detect touches on that new view. Currently, overriding touchesBegan gives a delay of around a second.
So, I load up the UIView and immediately keep tapping on the screen. It takes around a second for touchesBegan to be called. From that point on, all is well. However, I can't afford the ~second wait initially.
I have stripped back all the code in the UIView to just the barebones incase anything was clogging up the main thread, but the delay still persists.
How can I go about getting immediate feedback of touches from a newly presented UIView? Thanks.
-- EDIT BELOW --
I've been playing around with this for the past few hours. Even when creating a custom UIWindow and overriding sendEvent, the UITouchPhase gets halted when the new view is displayed. To begin receiving events again I have to take my finger off the screen and place it back on the screen. (I don't want to have to do this).
The problem seems to lie with the segue to the new view controller. When it segues, the touch phase is ended. If I simply add a subview to the current view controller, I see the desired functionality (i.e. instant responding to touch).
Given my newly presented view contains a lot of logic, I wanted to wrap it all up in it's own view controller rather than add it to the presenter view controller. Is there a way for me to do this and use 'addSubview` to present it? This should hopefully achieve the desired effect.
In the end, I created a custom view controller with it's own xib. Where I would have segued, I now instantiate that custom view controller and append it's view. This has eliminated the touch lag.
