When I run my application it works well, but during transitions between its views

  • 0

When I run my application it works well, but during transitions between its views I have a lot of CGContext errors in the console output, but the app still works well, no crashes or bugs I didn’t see.

Description: so I only run my app – all work well – but there appears error messages in the console:
enter image description here

And after any other view transition they appear again and again. So the question – how to fix this? And what may be the reason of this error messages? There a lot of views and code in my application so I don’t even know what part is error-prone.But these messages appear after transitions between all views in my app. Thanks in advance.

    Look for some method in your code where you call CGContextSaveGState, CGContextSetBlendMode, CGContextSetApha, etc. Chances are that you won´t find many places where you do that.

    Well, if you find it, look for some statement (just before those listed in your console log) where a context is created, and try to understand why it fails. You may set a breakpoint on that line and inspect the parameters to the CGContextCreate call.

    If you need more help, paste the code you have (hopefully) found.
