Another SEO tactic that can be used to promote your website is adding links on your posts to external websites. You can add links to websites that reviewed your app, or other rel- evant websites. When showing search results, Google algorithms take in consideration both linking to your website and linking from your website outside.

A few things you should take away with you when using Objective-C coding are: • Variables are written in ‘camel case’, e.g. appleMakesCoputers - the upper case letters appear like “humps” in the text • All lines end in a semicolon • Asterisks are used to declare a pointer, which is a variable that “points” to a physical memory address Now that you understand your workspace and some of the basics, a really simple application you can make is a cal- culator, there are many guides out there on the internet to guide you step by step through this process, but I will just outline the main steps.

  25. 25. The Endless Possibilities of Xcode 4 Technology This calculator would be pretty useless without a key- board, so naturally you’re going to want to add one. To do this, look underneath the Text Field’s attributes and head on down to keyboard. From the menu, select “Number Pad”, that’s it! Now all we need to do is link up our codes with the inter- face we’ve just created. Click on “File’s Owner” and go to The IBOutlets creates the code for variables that we can the “Outlets” pane, to add the code we need to drag the use later on. code to the correct elements.

And that’s all there is to it, quite a bit of work below. If you’re new to Xcode 4, but this is a good practice and if you’ve done everything correctly you can load it up in the iOS Simulator and show it off to your friends! So apart from the technical terminology, what have other people said about Xcode 4? The reviews look generally favourable from the older version, Xcode 3, but there are both advantages and disadvantages. When transitioning from Xcode 3 to 4, probably the first thing you will notice, is the new user interface, it’s quite a bit different. The tool- bar is near empty and there seems to be an LCD display in the middle that’s come right out of iTunes, not to mention Now we need to build the applications interface, go to the everything is now contained in a single window such as “View Controller” and add three labels, two buttons and the code editor, project navigation, inspectors and the rest. two text fields and make it look like the picture shown, or The workspace can be as minimalistic as a text editor or however else you like! you can choose it to be packed with a UI editor, document info, debugger and the media library. If you plan on using this application a lot, it’s rare that you will only ever have one project on its own; after all, it’s such a large applica- tion. For instance, you may be developing plugins or have frameworks that are in their own projects to later compile together with your main project.

  26. 26. The Endless Possibilities of Xcode 4 Technology Xcode 3 probably had the worst user interface out of all stop in the debugger, the stack information is now much the Apple products. It was called the “Groups & Files” list cleaner and it’s easier to reach, you can even view multiple and of course, you could improve it, but it was still very threads at once and you can make Xcode filter out threads cluttered and was one window that was trying to offer you that aren’t relevant. everything at once. At exactly the same time it was a file manager, target browser, find results list, SCM controller, Another new feature to Xcode 4 are jump bars. They’ve symbols list, breakpoint manager and much more. How- existed in other applications for quite some time now and ever, all that is now gone and Xcode 4 simply replaces the they’ve proved to be very useful. They let you navigate old “Groups & Files” list with navigators. You’ve got the through your entire project, but to those of you who are Project navigator, Symbol navigator, search, issue, debug used to the Groups & Files list will probably end up using and the breakpoint log. The Project navigator is the main the Project navigator and if you’re used to using Open one, it shows you your classes, frameworks, resources, Quickly, you’ll probably keep using that. It’s a great new products and the rest, but there’s an improvement. At the feature, but it’s navigation between files seems somewhat bottom you will find a filter bar with 3 pre-set filters, re- limited, and may only appeal to new users who prefer it to cently changed files, unsaved files and files with SCM status the other methods. and it includes a search field with which you can filter files across all projects in the workspace. This may be all good, but there is a problem, the inability to save filters or flatten An example of the new jump bars results so they don’t show groups. This functionality would replace the smart folders that you can find in Xcode 3, un- fortunately there is nothing like this in Xcode 4. The new and improved “Project navigator” Apple is well known for it’s different key bindings, however I can’t seem to remember all of them, they can be really Xcode 3 did have a real flaw, file management. It’s been annoying and they’ve added a load to Xcode 4. These can improved in Xcode 4, but it still has its issues. You can be really useful, but at the same time if you forget the key map groups to folders on disk, if you create a new file in binding you have to look for the command elsewhere or a group, it’s then added to that directory, but if you drag possibly mess up your work experimenting.

  27. 27. The Endless Possibilities of Xcode 4 Technology People seem quick to criticise Xcode 4, but I believe it shouldn’t be judged on what it is, but what it will be in Omar Al-Halawani the future with updates and more. There’s a lot of new He is a freelance writer who’s been interested in and interesting features, yet Apple seem to have got rid magazines and helping people for quite some years of a lot of features from Xcode 3 that many people loved now. He’s also been an avid Apple fan for years and and used constantly. The foundations are pretty much all owns a lot of iDevices! In his free time he enjoys there to build an Xcode that can compete with the likes of surfing the net and is an active member of many Visual Studio and Eclipse, they just need fleshing out more online forums, feel free to contact him at and some of the old features put back in. There are very omar6000@hotmail.co.uk few areas where Xcode 4 is worse than previous versions. or just Google Omar6000. The majority of those areas are where the features simply aren’t there, but where they may re-appear in future ver- sions. In every other area it offers major leaps forward in usability, performance and enjoyment. I’ve always considered Xcode to be the nicest IDE to use in terms of user interface, though it wasn’t ever the best looking one. It’s just the competition was so ugly and clut- tered. Xcode 4 however, genuinely is pretty. This may sound nerdy but, sometimes I love looking at it and admir- ing the amount of work that has gone into it. Apple has had some of the prettiest developer tools in terms of Inter- face Builder, Instruments and Quartz Composer for quite a while, but Xcode seemed dated when you compared it. It now feels like the sort of user interface you’d expect from Apple. Some people believe though, that Apple simply used iTunes as an inspiration for Xcode 4 and made the toolbars sparse to make it look like iTunes. It does lack some of the more advanced features of Xcode 3, but it’s wrong to say that iTunes was the cause or inspiration. iTunes isn’t particularly great; it’s old, clunky and somewhat ugly. In my opinion Xcode 4 is much closer to iLife or iWork in the sense that it’s modern, it puts a large amount of focus on the user interface and it tries to use great engineering to reduce the amount of work you need to do to create great results. It may be lacking a few features, but maybe with the release of Mac OS X 10.8 “Mountain Lion” this summer, there will be an update to Xcode that will make it more user friendly and packed with new (and old) features. All I know is, Xcode still has quite a long way to go to keep compet- ing with the other applications out there, but it still makes a hell of an IDE.27 www.icodermag.com 05/2012
