Xcode is a powerful suite of free development tools from Apple Computer that will allow you to create Macintosh applications, plug-ins, web components, applets, and more using languages such as C, C++, Objective-C, Java, and AppleScript.

Cocoa Programming for Mac OS X 3rd Edition.

LetвЂ™s say Apple comes out with a high-ppi iPad.

320В px document icon вЂ“ why not 256, darn it?.

ItвЂ™s unclear how these will be used вЂ“ they donвЂ™t do much currently вЂ“ but itвЂ™s not a bad idea to start planning now.

64В px document icon вЂ“ who knew: iOS apps can provide document icons.

58В px, iPhone 4 Settings/Spotlight вЂ“ thatвЂ™s right, you have to make both 57 and 58В px versions of your icon вЂ“ dвЂ™oh! Good luck aligning this if thereвЂ™s a line running down the middle of the icon.

Be sure to take this into account as you design your icon. iPhone OS trims 1 pixel from each side of your artwork and adds a drop shadow. This size is controversial! AppleвЂ™s docs actually say the icon is 50В px, but then thereвЂ™s this note: The final visual size of this icon is 48 x 48 pixels.

48В px, iPad Spotlight вЂ“ yup, the iPad uses a different size for Spotlight and Settings.

29В px, iPhone Settings/Spotlight, iPad Settings вЂ“ used in these table views.

Sadly, you canвЂ™t provide the 175В px version directly.

512В px, iTunes вЂ“ Used in iTunes and in the App Store, where itвЂ™s sized down to 175В px.

114В px, iPhone 4 вЂ“ make sure your icon shines on the Retina Display.

Also, itвЂ™s a good practice to disable them if you donвЂ™t really need them. Just a reminder not to leave the zombies enabled, when you submit your app to the App store. Now instead of wondering whatвЂ™s going on and which exact object produced the problem, youвЂ™ll see exactly which class is the trouble maker, and youвЂ™ll debug it quite fast.

In вЂњVariables to be set in the environmentвЂќ (thatвЂ™s the list at the bottom, be careful which one you edit) click the вЂњ+вЂќ button and for name of the variable enter вЂњNSZombieEnabledвЂќ and for value вЂњYESвЂќ.

Double click your executable in the вЂњExecutablesвЂќ in XCode.

When this feature is enabled, a dummy object (a zombie) is kept on the place of every released object, thus allowing to debug objects which were released already. The solution to overreleased objects are the zombies. ThatвЂ™s really tough to debug with NSLog вЂ¦ NSLog is helpful, but you need to put 1,000 NSLogs around to fetch where is the problem. This is because the object is gone, there is no information what class was it, or what source file or anything else. In this cases everything (and indeed everything) you will get in the console will be just : WhatвЂ™s happening most though is that you will be sending a message to an overreleased object вЂ“ i.e. Start using the debugger, if you recently added a new object to the class youвЂ™re working on, put a breakpoint at the line before the freshly added object is used for the first time and check the values in the debugger.

Something else that is not very likely to happen.

This article however is about how to make the process easier, in some cases easy as a piece of cake.Д®XC_BAD_ACCESS means that message was sent to a point in the memory where thereвЂ™s no instance of a class to execute it. You have to accept the fact that sooner or later you will need to debug an EXC_BAD_ACCESS problem and most probably wonвЂ™t be easy to. This article is from, useful for debugging the annoying EXC_BAD_ACCESS exception.
