Creating a Calculator- Functions

Today I was working on the function buttons.  The x and / buttons still need some minor work. The number one and number two functions are why it isn't working - it resets one of the numbers to zero and then multiplication and division are thrown off. Another thing that I did today was to move the math properties " x , / , - , + " to a function. There is now a bit less code, but I will have to write more to make it functional again.

Gimping New Things Weekly

Over the past few weeks I have been creating images in Gimp and have gotten quite proficient in it. These are some of the images that I have created:

Yesterday my mom was using Edmodo. She wanted a achievement badge and this is what I came up with:

 Edmodo was mean and didn't accept it. I had to change it to:

Which they made into:

I like my own much better, but there is nothing i can do about that. :(

Creating a Calculator- NSString

Calculators need to use math and a string to display their information. Some useful tips on creating a string are:

NSString is a string

To set NSString:

• NSString *astring = @"Words"

NSString has %@(String in a string), %i(integers in a string),  %f(float in a string), and a few more

• NSString *astring = [[NSString alloc] initWithFormat: @"Words %@ then %i next %f", *anotherstring, anint, afloat]

Creating a Calculator- Labels

While creating a calculator it is useful to make the word on a screen. To do so one must first drag a label into the .xib file from the Utilities > Attributes Bar. Next drag a line from the (left click on) Label Menu > New Referencing Outlet (Circle) to the Assistant Editor Window. Naming this "label" helps.

Creating a Calculator- Buttons

I have started making a calculator to test buttons, math, and errors. Creating a click-able button was easier than expected. All that was necessary was to, in the .xib file, drag a button onto the screen while using the Utilities > Attribute Bar. All that was needed was to then left click on the button, drag a line from the touch-up-inside circle to the code in the assistant editor, and name the function.

Getting Started

I have always liked making games and throughout my life I have used
Scratch, GameMaker, and a few other programs to do so. Currently I
have started making apps using Apple's SDK.  Apps are programmed using the C languages. Because of this, one of the first things that I did to start with the SDK was to learn C++. One small problem was that, although  C++ is useful for text based applications, Objective C is more useful when dealing with objects. This is the reason that I am now learning Objective C while making apps with it.

This Blog is about all the apps I am making and the process involved.
