Déjà, dans ton code tu faisais un "=" qui comme dit plus haut attribuait à une variable Var1 une NSString, donc même si Var1 était déclaré NSMutableString, au final dedans c'était un NSString comme objet. Ensuite à un moment tu as mis directement [NSMutableString initWithString:...], or "NSMutableString" est une classe, et "initWithString" est une méthode d'instance (donc à appeler sur un objet) et non une méthode de classe. On n'appelle jamais directement "init" sur une classe, on passe par alloc + init, ce qui donne [[NSMutableString alloc] initWithString:...]. Et si tu fais ça, il ne faut alors pas oublier de balacer le "alloc+init" par un "release" à faire plus tard quand tu n'as plus besoin de ta variable (ou un autorelease).
Lire la doc sur la gestion de la mémoire pour ça, c'est un concept très important et la base de la programmation ObjC NSMutableString* var1 = [NSMutableString stringWithFormat:@"%@ %@ ! "
XCode. Soumission AppStore. Mac OS X keyboard shortcuts. To use a keyboard shortcut you press a modifier key with a character key.
For example, pressing the Command key (it has a symbol) and then the "c" key copies whatever is currently selected (text, graphics, and so forth) into the Clipboard. This is also known as the Command-C keyboard shortcut. A modifier key is a part of many keyboard shortcuts. A modifier key alters the way other keystrokes or mouse/trackpad clicks are interpreted by OS X. Here are the modifier key symbols you may see in OS X menus: Startup shortcuts Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears).
Sleep and shut down shortcuts.

It's a much easier process for our beta testers than syncing with iTunes to install the app! They just click on a link from their phones, and they can download the app immediately! How, you ask? Apple has made this possible since iOS 4.0, but not many developers have noticed it's available. TestFlight has make a great wrapper on top of this functionality, but it's possible to do it without using TestFlight too! First, build and archive your application from XCode. Open Organizer if it's not already open. This is the critical step.
Next you'll need to fill out the form that appears. At this point, XCode prompts you to save the files to a folder. You just need to create a web page with a link to the .plist file using the special itms- protocol. <a href="itms- Download Geoloqi </a> Note: This is not going to get you around the 100-device limit that Apple imposes.
Facebook Releases Biggest iOS SDK Update Ever, Plus iOS 6 Hooks And iOS Dev Center. Facebook has just released a major overhaul of its software development kit (SDK) for iOS, including support for the forthcoming iOS 6, plus a new iOS Dev Center that includes documentation and resources for developers.
Facebook promises the new features in the SDK will make it easier to develop Facebook-integrated mobile apps. Highlights include: -Improved session management, meaning that it will be easier for developers to handle authentication to Facebook. -Pre-built interface tools for displaying user profile pictures, Facebook Places and more. -Improved feature support for Objective-C, the native programming language of iOS, including better memory management. Sarah has also taken a closer look at the Dev Center, here.
