iOS 6 Here I come!

Well, I have gotten the Blue Quadratic Solver up and running on iOS 6.  It took me longer than I thought, but things have been busy here with the Sandy Hurricane and now trying to get my students back on schedule.  But BQS will now use the full screen of the iPhone 5 and shrink back to size if run on an older iPhone.  I still need to update RUExempt and the CoolConverter, but that will come in some time.  I will try uploading this weekend and see how it goes.  I did have one error though.  It was another Mach O linker error like in my previous post.  So I followed my own directions but the error still persisted.  So I went back to Stackoverflow and found this.....

Click on your project in xcode. Then, click on the target. Go to build settings and look for valid architectures. Delete armv7s from the list of valid architectures and just leave armv7.

It worked!  Hope all is well with everyone.

Another "Review"

I made the news paper!  Well, my high school's news paper.  Which by the way, is an excellent publication.  I was very excited about being interviewed and I wanted to share it with you.  Here is a link, ENJOY!!!

My App Got Reviewed!

Well, this month my App, the Blue Quadratic Solver, was reviewed by a website call Ray Wenderlich. This is a blog that has tons of iOS tutorials and I have learned a lot from it.  Great resource for all sorts of information.  Here is a link to the review.  You have to scroll down a bit to see it because there are many others that got reviewed as well.  But, I am pretty excited.  Hope you all enjoy it!

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!

Updates again!

Well, I am updating the Blue Quadratic Solver right now.  I am using a static library called Core Plot to make a graph of the equation for visualization.  It is a bit tough because many of the tuts out there are a bit old.  Also, many of the examples do not use ARC which I have only done.  So I am struggling, but all the helpful people at Stackoverflow have been very nice to me!  I have even been able to get a great looking xy scatter plot going and will upload a pic soon.  Can't wait to be done and get this up on the App Store.  I think it will be one of the best quad solvers out there!

Both got accepted!

Both the Cool Converter and the RUExempt? Update got accepted last night!  It was pretty quick.  Now I have three Apps, onward and upward.

Submitted Cool Converter

Well, I got the Cool Converter up and running the way I wanted.  So I submitted it the other day.  I also updated RUExempt? with a new panel that will calculate your total grade for the year.  That is awaiting review as well.  Hopefully I will hear soon from Apple!

Temperature Converter App

Well, I just finished another App called Cool Converter.  It is just a temperature converter, but I went on the App store to find some and looked at all the reviews and tried to make mine have some of the features that people were complaining that others did not have.  I also, used a custom keyboard, and sounds!  The keyboard keys click and if your device supports vibrate, it will vibrate on any alerts popping up.  I still have to work out a couple of things to get it fully ready, but they are minor, color and such, so I should be able to upload to the App store soon for review.  I will keep you posted.

RUExempt? goes live!

Well, RUExempt? Went live last night. I am pretty excited to have two Apps on the App store. I'm going to ke at it and see what other tools I can come up with. Still toying with the idea of making a graphing App.

So I haven't heard yet from Apple.  It has been over a week.  But they say from one to two weeks, is the norm.  I did not do the picker from a popover view on the iPad, I used all the same code.  The picker doesn't look that bad on the iPad, and most of the users will be using the App on their iPhones, and that turned out just great.  Hopefully I will hear some good news soon!

I think I've got it!

So the action sheet did not work for me.  So I tried a couple of different things and now I have the UI that I need.  When the user hits the text box, a picker comes up.  They can then choose the grade, both the letter and the sign. (Yes, I was able to make it a double wheeled picker!) I am going to code everything in this weekend and make sure it runs on both iPhone and iPad.  Although I will need to do a popover view for the picker to work on the iPad.  Hope it all goes smoothly.

Grading App rejected!!

Well, my grading App was rejected by Apple because it did not have a great user interface.  So I am working on making the grade selection via a UIPicker View.  It is a bit tough, but I think I might have it using an action sheet.  But since I have multiple text inputs, I am having trouble changing the inputs.  I will let you know how it goes.

Upgrade to the blue quadratic solver

I am about to send in an update for the BQS. I have added another screen tha will show the user what the radical form of their quadratic looks like. This was done on the advice of some of my math friends at the high school.

Grading App

Today I uploaded another App for review.  It calculates if the seniors in my High School are exempt or not from final exams.  It will also let the students know what they need in the fourth quarter to be exempt, or lets underclassmen find out what to get on the final to get their desired grade.  Had a bit of trouble with some of my variables, but was able to iron it out with the help of my friends at Stackoverflow, one of the best online sites for help with programming.  Hope the App gets approved soon!

The App is LIVE!!!

The App got accepted!!!  If you would like to check it out go to;

It is a quadratic equation solver that will tell you the roots of your quadratic, give you the imaginary number if there is one, the discriminant, the vertex, and the axis of symmetry.  Hope you like it!

New App!

I just submitted a new app to the app store.  Hopefully it will be accepted.  It is for dealing with the quadratic equation.
