Beginning Objective C Programming at Mac App Store analyse

Für den Einstieg in Objective-C sehr gut. Bringt die Grundlagen verständlich bei. Gefällt mir!

This app is a joke. Okay, it is cheap, but still. The app is a non-sizeable (!) window containing about a dozen (web)pages ("Chapters") explaining various aspects of Objective C. The "chapters" are: - Installing XCode (seriously? If you could download this "app" from the Appstore, you should be able to download Xcode as well or you should focus your skills one something like gardening instead of programming.) - Getting Started (Creating a Hello World application using an Xcode wizard) - Variables - If-Else statements - Objects - Methods - Managing multiple objects (basically a short into on NSMutableDictionary - NSString comparisons (how to compare two NSStrings…) - Loops (while and for-loops) - Arrays (another short intro on NSMutableArray) - Building your First iPad App (a very simple iPad App mostly generated by the Xcode wizard) - Another iPad example (a very simple Dialog-Application: Calculate an area from the radius) - Going further (a single sentence expressing the authors hope that the reader had fun) Obviously it is intended for an audience which has zero experience in programming, because e.g. the "Chapter" Variables explains what a variable is, what a type is, etc. The same goes for the if-else "Chapter". If you know C/C++/C#, half the "chapters" are useless for you. The objects and methods chapter is actually slightly interesting, but does not go into detail at all, at least the concepts will be familiar to you. For a beginner, the treatment of an object is by far too superficial. Similarly the iPad chapter is interesting for introducing the concepts of outlets and actions, but it too is just a simple example without much explanation. Overall it looks like this "booklet" was written in an afternoon, and the bottomline is: spend your money on something else, it will be better spent.

Cant install. I get an hash error.

I bought this app to help me learn how to design iPhone apps, and its a great beginner guide, but I would really like to see the creator add more content because I believe a lot of important things are not covered in this guide. Also, there are a few spelling errors and some bad code that makes the quiz button cover the previous button when you make the apps window smaller, which also makes it overflow in to the table of contents. I would also like to see individual quizzes for each chapter instead of one big quiz with questions that you dont know how to answer until the last chapter. PLEASE add more content and fix these problems! It would make this app 2x better. **EDIT** Very dissapointed to learn that the creator made another objective c app for $2 and promotes it with this one... very stupid idea. Please make it one entire app.. changed my rating to 2.

Started going through this program, everything seemed fine except when I got to the fifth chapter on Classes and Objects. You are told to insert the following code into a file, but they dont tell you where to insert it. The quiz is very basic and only has 10 questions that never change. Great video on the first chapter got me excited about this program and then they dont use it again till the end. Would have been great if they would have given text that could be copied and pasted. Boy what a time saver that would be. This program has the potential to be very good, but how it is presently, I could not recommend it to anyone.

I have limited knowledge of objective c but recently made the decision to learn the language. I have read around a few books but this app really has put the whole process into perspective and explained each role i.e. methods, objects, variables etc. in a straight forward and understandable way. If you have a little knowledge on objective but really want a nudge in the right direction then get this app! I hope this developer relaeses a more in depth version soon!
