Change DEPLOYMENT_TARGET back to iOS=8.0 about react-native-blur HOT 15 CLOSED

Nope, we can rewind it back to 8.0! Should I do it or you want to commit it by yourself?

from react-native-blur.

I can do it, thanks 💃

(We do support iOS9 only, but I have that feeling client will request iOS8 resulting in removing quick-actions support, but want to avoid warnings from side menu)

from react-native-blur.

So, any progress so far?

from react-native-blur.

Yes, I will get back on that today.

It's a long day "today", isn't it? 😄

from react-native-blur.

It is, indeed 💃

So I'm kind of confused on this (and new to RN), will this work on iOS 7? Will it fail spectacularly or gracefully if its not?

from react-native-blur.

As a follow up question, how do I detect <= iOS 7 so I can fall back to something else (sweet library btw)

from react-native-blur.

yo @9mm! Unfortunately, it doesn't support iOS < 8, because it relies on UIVisualEffects.

from react-native-blur.

Based on http://stackoverflow.com/a/18568657 @9mm, it will run flawlessly when Base SDK >= 9.0. As long as you do not render component with <BlurView>, it won't fail at all. So best you could do is to detect in React Native what version you are running and then - based on that, either display it or not.

On the other hand, if there's demand, we could add in a support for older devices, by wrapping setBlur function with:

if(NSClassFromString(@"UIBlurEffect")) {
   // method goes here
} else {
  _visualEffectView = [UIView new];
  _visualEffectView.backgroundColor = [UIColor blackColor];
  _visualEffectView.alpha = 0.2 // or 0.6, 0.9 depending on string `blurType
}

and fall back to using opacity with black background in other case.

@grabbou I think it'll be more valuable if we can eventually rewrite this one in a favor of custom blur implementation we can share between iOS and Android

from react-native-blur.

I am not sure if there's any way to share custom blur implementation between Android & iOS. AFAIK there were few attempts back in the day to support blur effects on IOS prior to UIVisualEffects but I am not sure it's worth reinventing something, that works quite nice on system level and (hopefully) is well optimised.

@grabbou that is very interesting... great piece of information to know. Is there a way to detect iOS version in React Native, without the use of 3rd party libs?

from react-native-blur.

Yeah, if you are on Discord, ping me (same nickname) and I'll send you over some snippets tomorrow from work. I've done it in the past, just need to find it :)

This one looks a bit outdated now.
