default colors while switching views

[cpg]

I tested my apps with regular (non-developer) people, on the road.

One of my apps is darkish-ish (maroon). One thing that people notice is that in between taps, there are these flashes of bright white full screens.

Could you point out where the colors for these "base" screens can be configured?

If they are not configurable at the moment, perhaps this bug can serve to make them explicitly configurable so that the user does not perceive as much the lag involved.

Side note: perhaps the lag can be addressed in the platform?

I think the best solution for this would be to come up with a JSON representation. But this is something we should think carefully before making the decision. Especially since our goal is to support this cross platform.

Let's keep this open until we figure out how to do this (not just for the body but for everything else, including the navigationbar color, etc)

For now, to serve this purpose you can universally set the background color that loads initially (before it gets reset by the background color loaded from the JSON) by adding this line to JasonAppDelegate.m's - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method:

[[UITableView appearance] setBackgroundColor: [JasonHelper colorwithHexString:@"#00ff00" alpha:1.0]];

That works well, thanks! It makes the switch in views less noticeable (less clumsy) and more smooth.

Couple of ideas:

• set this "default background" with a special settings block that it's parsed from the very first url. this introduces state, which is not great.
• set this "default background color" from the first view load and mirror that from each new loaded url. Not perfect, however, for the most part most apps will keep the same or similar background color, not changing all the time, I would imagine. So this would do the trick the vast majority of the time at the expense of mirroring the view background (e.g. after a view has loaded) each time. This has the advantage of covering almost everyone in the platform without changes in their code.

Oh, I see what you mean with the nav header.

In modals, the header comes up all white sliding in from the bottom, so it's noticeable. Not as much as when the whole thing is white, but yeah, it's noticeable for darker apps.

i was going to submit an updated version of my app to the ios app store. then i thought the header being by default while may have a similarly simple solution. it's most visible in modals sliding in from the bottom to the top of the screen with a white header (and the rest with the darker default I set up).

we tried two things, none of which worked (together or combined).

one was adding:

    [[UINavigationBar appearance] setBackgroundColor: [JasonHelper colorwithHexString:@"#00ff00" alpha:1.0]];

and there is no visual change that i can tell.

the other was to merge the latest changes from the develop branch, specifically the fix to #50. same thing.
