  • BetterAuthorizationSample weird???

    - by Nano8Blazex
    I have a quick, newbie question... I just started looking through authrozation services and Apple's BetterAuthorizationSample... for some reason, I just can't get the hang of it. For example... I deleted the HelperTool and InstallTool and SampleTool.c and all references, but why does the program seem to continue work like nothing happened at all even after a clean build? Even commenting out all the code in SampleTOol.c doesn't seem to affect the way the program runs? Thanks

  • Animate a GIF using Core Animation layers?

    - by Cliff
    I'm trying to animate a GIF and I hit a roadblock. I have an example of what I'm trying to do that uses the individual frames of the GIF and setting the animationImages property of a UIView. However in my project, the thing I want to animate is drawn using Layers. I'm looking for a quick and easy way to animate the frames without introducing too much complexity. Is there any animationImages equivalent with Layers? Does anybody have any ideas?

  • Using a constructor for return.

    - by Fecal Brunch
    Hi, Just a quick question. I've written some code that returns a custom class Command, and the code I've written seems to work fine. I was wondering if there are any reasons that I shouldn't be doing it this way. It's something like this: Command Behavior::getCommand () { char input = 'x'; return Command (input, -1, -1); } Anyway, I read that constructors aren't meant to have a return value, but this works in g++. Thanks for any advice, Rhys

  • asp.net web app - writing data to access or error logs?

    - by chris
    I'm looking for a quick way to log some data - I seem to remember a way to write to the access log, similar to System.Out.Println() but I can't seem to remember how to do it. I can't attach a debugger, nor can I add additional information to the web app via Response.Write(). Is there a simple way - a single statement with no configuration changes would be ideal - to write to either the error or access logs?
