ios core-graphics cgbitmapcontext
if I’ll test a function of my app in the ios-simulator the simullator crashes. This is the error: Apr 12 22:18:57 Pattis-MacBook-Pro.local CameraAPP[12374] : CGBitmapContextCreateImage: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.Hope

I have been working on this project for the last week and everything has been running fine in the simulator.

I am definitely in the steep part of the learning curve on Objective-C and Xcode, and these errors do not ring a bell at all because I haven’t used any of the

I have developed a MonoTouch iPhone application. Currently it works by parsing a large amount of xml data that generates all of my objects. I tried to improve the start speed by serialising these objects and storing in an sql lite database. But this was actually slower. What I have done instead is to write a program that pre-parses this xml and in turn writes out class files that can simply be compiled and the objects instantiated at runtime.This works and is a huge speed increase, but I can on

From using the Allocations instrument to track my app’s memory usage I’ve noticed that throughout the runtime of the app the memory usage keeps going up. Looking through the heapshots I can see that the largest chunks of memory are being allocated by a method called CJPEGCreateImageDataWithData in the library GMM. I can’t find anything online about this happening, but it certainly looks like this is responsible for my app’s memory-hogging. Here’s a screenshot of the pertinent part of the Allocat
