About UIGraphicGetCurrentContext() in iOS

SteveLeung — Mon, 21 Jan 2013 06:49:09 GMT

Hi,

I am now using the ArcGIS Server runtime API 10.1.1 in my iphone app, but I found that I couldn't obtain the AGSMapView when I used UIGraphicGetCurrentContext(). However, it works in the previous version of ArcGIS Server runtime API. Would anyone encounter the same problem? How to resolve this problem? Thanks!!!

Regards,
Steve

With 10.1.1, the Runtime SDK switched to rendering with OpenGLES. You cannot snapshot an OpenGLES view the same way you can a UIView using UIGraphicsGetCurrentContext(). Apple has a technical article on working around this issue.
