BLue Quadratic is finished!

Well, I do believe that the BQS is done.  I have fixed some errors that were graphing the axis backwards!  Fixed a rotation issue that made the "i" disappear on the radical view.  And made the annotations appear with a tap and disappear with a double tap!  I am going to submit for iOS 5 sometime this week.  After that I will update it for iOS 6, but the only issue I need to fix for that is a rotation issue and to take some new screen shots.  All things that should not take more than a couple of hours.  But I think I am going to hold off until more people update to iOS 6.  I am glad to see that my post about the iOS core plot error, got some hits and that it helped people out!  I sure have gotten a lot of help with my concerns from all over the web.  Especially Stackoverflow and Core Plot.  Have a great day!

Error with iOS 6 and Core Plot

Well, I think I have the BQS all ready to got for iOS 5 with the new annotations and fixes.  So I figured I would try and get it updated as well for iOS 6.  So I copied the folder and ran the copy in Xcode 4.5.  I had to fix some things that had been depreciated but finally I got it to work in the simulator just fine.  Then I ran it on my iPad and got an error!

ld: file is universal (2 slices) but does not contain a(n) armv7s slice: /Users/douglasjmerritt/Desktop/Xcode 4.5/BlueQuadCalc copy/libCorePlot-CocoaTouch.a for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This error did not allow me to run on my iPad.  So I did a bit of searching and found that I have to change the Build Active Architecture Only to YES.  After that, it all worked fine.  This setting is in the build setting.  Hope this helps someone!

I Love Core Plot!!

The BQS is able to graph your quadratic now.  And through the help of the great people at Core Plot, I have added touch notations!  So if you want to find a point on the graph, just touch it!  If you are looking for a great static library that will graph for you, Core Plot is the way to go.  They have some great examples on their website, and plenty of helpful people, both at their website, and on Stackoverflow.  You should really check it out.  My next move is to update the BQS with the touch annotations, but I am making sure the App handles all kinds of uses.  I did find two errors on my part.  One, I cut short the number of decimals in my float variables so when graphing a number with something like 0.0003, it would transfer it as just zero.  So I fixed that.  Also, when rotating on the radical screen, in landscape you would lose the i's.  I just needed to adjust the struts and springs.  So these will all be addressed with the next update, but I will do an update first of iOS 5.  I am working on transferring all the code to iOS 6.  When that gets done I will update once again.  Hopefully the BQS is finished and I can start working on my next App.  A data analysis program to be used in my Physics classes!

Uploaded the BQS update

Well, I uploaded the new binary for the next version of the Blue Quadratic Solver.  It is version 2.0 and can graph your quadratic as long as it has real roots.  Apple's servers were down yesterday so I got an error; Unable to process application Info.plist validation at this time due to a general error.  A bunch of people were having the same problem.  I actually emailed Apple and they called me back in about 2 minutes to let me know what the problem was!  I just love Apple!  So I hope you enjoy the new version.  Soon, I am going to send in the update for the Cool Converter so it supports device rotation and Rankines as another temp scale.  I am also going to try and make the BQS graph equations that do not have real roots.  I will keep you posted!
