To give a more detailed example: in your .h file do @interface YourClass : YourSuperclass<NSURLConnectionDataDelegate> in your .m file do @property (nonatomic) NSMutableData *imageData; @property (nonatomic) NSUInteger totalBytes; @property (nonatomic) NSUInteger receivedBytes; And somewhere call NSURL *url = [NSURL URLWithString:@

Possible Duplicate: Protected methods in objective-c The way to declare private properties is simple. You declare that in extension that's declared in .m files. Say I want to declare protected properties and access it from the class and subclass. This is what I tried: // // BGGoogleMap+protected.h // // #import "BGGoogleMap.h" @interface BGGoogleMap () @property (strong,nonatomic) NSString * protectedHello; @end That one is compile. Then I added: #import "BGGoogleMap+protected.h" @implementation BGGoogleMap () -(NSString *) protectedHello { return _ } @end Problem starts. I can't implement

After update xcode to 4.5 version I have an error Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1 I read about error like this after update, but changing the architecture in target's builds settings doesn't help. It's work on simulator but not on device. The whole error CompileC /Users/psitkowski/Library/Developer/Xcode/DerivedData/Jasiu2-gskaidiujznurtdqnebvtogjtdnd/Build/Intermediates/Jasiu2.build/Debug-iphoneos/Jasiu2.build/Objects-normal/armv7/maxvid_decode_arm.o Classes/AVAnimator/maxvid_decode_arm.s normal armv7

I need to set translatesAutoresizingMaskIntoConstraints to NO . By default it is set to YES (to assist with the majority of apps that are transitioning from struts and springs to the new Auto Layout). Is there somewhere in Xcode where the default can be changed from YES to NO ? Or do I have to manually set it for every view? This is a great question - and one I've tried to find an answer to myself. Sadly, it looks like there is no "quick fix". Currently, Apple considers Constraint-based layout Opt-in - even naming a section of the UIView Class Reference : Opting in to Constraint-Based Layout

A question here: Xcode 4.5 corrupting XIBs? illustrates the problem and solution for xcode 4.5 creating nib files that can not run on ios5. Does anyone have a solution to prevent the auto layout checkbox from being defaulted to on? I'm worried that in the process of development, I will forget to unchecked that box. There's a way, but it's kinda convoluted and, I might add, not recommended. You can open your template files located in: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/User Interface/ , in each directory, there

After updating to XCode 4.5 and installing the developer tools I can no longer run the 'git gui' command from the command line. It says: $ git gui git: 'gui' is not a git command. See 'git --help'. I'm running this version: $ git --version git version 1.7.10.2 (Apple Git-33) Searching the git docs (http://git-scm.com/docs/git-gui) shows 'git gui' should be available, and hasn't changed since version 1.7.7. So did this Apple version of git remove this command? I use it all the time! Apple did indeed remove the 'git gui' command, probably because they were removing X11 which 'git gui' is based
