So I have been working on an IOS app built-in unity3d. When I try and push the app to
my iPhone in Xcode I receive a "Use of undeclared identifier 'CreateTextureFromCVTextureCache' when
doing the build.
The full code snippet is in the link below:
https://drive.google.com/file/d/1ZDb0pbHCfI8zmroe9F34Pk_EIt2C585S/view?usp=sharing
I hope you can help.
'CreateTextureFromCVTextureCache' is deprecated in Metal API, use 'CreateBGRA32TextureFromCVTextureCache' instead.
After further investigation I noticed that the CreateTextureFromCVTextureCache class is deprecated for Metal graphics api. Hope This help others.

Recently I submitted my app on AppStore with a method setting badgecolor of tabbaritem.
[[[AppDelegate globalDelegate].tabBarController viewControllers] objectAtIndex:1].tabBarItem.badgeColor = kTabBarBadgeColor;
This badgeColor came in iOS 10 only and my app supported iOS 8 and above. I had no idea about it and the app got approved. Now, I have to resubmit my app with fixing this issue.
I want to know if there is a way to find out such cases where methods get deprecated or are visible in specific OS versions only.
By changing target of Xcode project you can see errors & warnings while building.
If you need more info,
You can visible all API changes like Added,Modified & Deprecated variants in Apple documentation
it will give you searching options for both Swift & Objective C
Searching UITabBarItem Instance Property badgeColor. it gives API changes are none.Supporting SDK's version
SDKs
iOS 10.0+
tvOS 10.0+
Searching finishedSelectedImage instance method of UITabBarItem.
SDK
iOS 5.0–7.0 Deprecated
Deprecated Use selectedImage with UIImageRenderingModeAlwaysOriginal
instead.
I am using Diagnostic plugin to my IOS IONIC 2 app. i am getting an error when i do ionic build ios with production mode (--prod). Could anyone help me how to solve this issue?
Thanks in advance:)
error: no known class method for selector
'isPedometerEventTrackingAvailable'
return [CMPedometer respondsToSelector:#selector(isPedometerEventTrackingAvailable)] &&
[CMPedometer isPedometerEventTrackingAvailable];
Check github issue.
Also here.
Either update your Xcode version to 8.0 or above.
cordova.plugins.diagnostic#3.2.0 adds support for the new
UserNotifications framework added in iOS 10. To build using v3.2.0,
you will need to use XCode 8+ because there's no way to conditionally
include a framework using the tag in the plugin.xml.
Or downgrade your diagnostic plugin to 3.1
I was using this function to change the font size of a label in UIButton.
Like this(SWIFT) :-
Button!.titleLabel?.font = Button!.titleLabel?.font.fontWithSize(12)
I want to see the availability of this funtion for ios 7. So i see the quick help documentation of Xcode. There it was mentioned as iOS (8.0 and later)
Then i went on to search for the appropiate funtion on apple website but there it is wriiten that its available from Available in iOS 2.0 and later. See Here for ref.
Please do let me know which one to trust.
I saw answer but i am not that satisfied as i check the other class
Like NSMutableAttributedString for swift
here it is written as available from iOS (3.2 and later)
My strong guess is that since Swift came out together with iOS 8 Apple's documentation won't show anything being available before that. If you check the same method on Objective-C side, you'll see the same as on the web:
I also have a project targeting iOS 7 with calls to fontWithSize in Objective C and they work fine. So there should be no reason for it to not be available on Swift side of things.
Also found information from Apple's Radar system:
Engineering has the following feedback for you:
This is expected - Swift was not available until WWDC 2014 and the introduction of iOS 8, therefore the availability of these methods and contstants in Swift is correctly documented as iOS 8+.
Thank you for your feedback. Engineering has determined that this issue behaves as intended.
So clearly this is the Apple way of doing things, as usual.
in Objective C
it is still 2.0
I'm using Accelerate.framework to get some informations,
It works fine on iOS Device, but occurred error when I using Simulator,
Use of unresolved identifier vDSP_vsq
Anyone can help ?
it looks like an issue of swift accelerate.framework
it works when I using the method on Objective-C class, then call it by bridging-header
Strange bug in iOS 6.0 sdk. Apple promised to deliver full reminder support via api, to allow thirdparty applications to read and write reminders on behalf of user. There is new methods in SDK to init storekit for use with reminders.
But seems like main method to make it possible - just not present. Both GM version of XCode 4.5 and simulator/ios-6 upgraded device shows that EKEventStore:initWithAccessToEntityTypes is not present in SDK and attempt to call it on device/simulator crashing application with
Error invoking method 'EKRemsIsGranted' on 'CEKtils' because
-[EKEventStore initWithAccessToEntityTypes:]: unrecognized selector sent to instance 0x13a59140
Interesting that this method is also mentioned and described in MacOs 10.8
but in iOS sdk it is mentioned but NOT described
Seems like apple devs forgot to "enable" it on iOS. is it possible at all or I missing something?
There's a description of the event (and some other useful information) here. You might also double-check that your UIEventKit framework is properly linked and up to date.
