Disable Automatic Reference Counting for Some Files

I have downloaded the iOS 5 SDK and found that ARC is a great feature of the new Apple compiler. For the time being, many third party frameworks don't support ARC. Could I use ARC for my new code and keep the current retain/release code unchanged? The ARC converter doesn't work here, because some frameworks, such as JSONKit, cannot be converted to ARC by using the converter.



The answer is to add -fno-objc-arc to the compiler flags for the files you don't want ARC.

It is not very intuitive how to disable ARC on MULTIPLE files, for a while I was do it one by one until a figured out how to do that.

1. Select desired files at Target/Build Phases/Compile Sources in Xcode (CMD+click or Shift+click)
2. PRESS ENTER (double click will reset the selection, so it doesn't work)
3. Type -fno-objc-arc
4. Press Enter or Done

iOS 7 – Status bar Issue

Hi All ! I know everyone is struggling with new iOS7. One of the major issues for making app-user-interfaces compatible to iOS7 for apps which uses custom-layouts, I’ve found a quick solution & I hope you are going to like my quick-fix.

Step 1. Open project. Open to target-info.plist & add entries as illustrated here.

Step 2. Open AppDelegate. m & navigate to the app didFinishLaunchingWithOptions method & make sure you’ve a black window – see sample code below.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {     self.window = [[UIWindow alloc]                   initWithFrame:[[UIScreen mainScreen] bounds]];     self.window.backgroundColor = [UIColor blackColor];     // Override point for customization after application launch.     self.window.backgroundColor = [UIColor blackColor];     // set root-view-controlller - look into step-4     [self.window makeKeyAndVisible];     return YES; }

Step 3. Check the current iOS version.

1 2	#define IS_IOS_7    ([[[[UIDevice currentDevice] systemVersion] \ componentsSeparatedByString:@"."][0] intValue] >= 7)

Step 4. It’s an obvious that you are going to set a view-controller/navigation-controller/tab-bar-controller as a root-view-controller of your application-window. So, Assume, we’ve a tabBar as a variable/property of a tab-bar-controller & following code will explain you how to add & set it in a window. (Make sure you code frame-size with conditions if you are targeting both iOS7 & 6)

1 2 3 4

self.window.rootViewController = self.tabCtr;     self.window.rootViewController.view.frame = CGRectMake(0, 20,             self.window.rootViewController.view.frame.size.width,             self.window.rootViewController.view.frame.size.height-20);

And you’re done. You would not need to do after this patch for iOS 7. I hope it helps to you all. Cheers.
