Setting and Testing localizations in iOS 6

To Set:
http://stackoverflow.com/questions/5349066/how-to-localize-my-app-with-xcode-4

7) in your code use  NSLocalizedString(@"TEST", @"test") where the first arg is the string and the second arg is the description (optional can be nil)
1) Create strings file

2) call it "Localizable.strings"
3) fill the localizable.string with all the english terms you use in the app "TEST" = "TEST";
4) file inspector "Make Localized"
5) + add localization you want
6) add only the localizable.strings file to the list
8) translate and smile

To Test:
http://useyourloaf.com/blog/2013/07/22/using-launch-arguments-to-test-localizations.html

1) go into the current Scheme
2) goto arguments
3) add "-AppleLanguages (Russian)" without quotes
4) click on and off to test the various languages and smile

How to create a subview that will be a popup on large devices and full screen on small ones in iOS 6 with ARC

Universal apps are becoming more and more necessary today. They are becoming more complicated as well. At least they don't hundreds of different size screens to deal with like android.

First you should have a subview that is the size of a standard smaller screen (itouch, iphone). We will call this "SearchViewController".  You might want to use a delegate to interact with the views but we won't worry about that in this exercise.

in the SearchViewController.m;

-(void) closeView{
    //all keyboard items should have "resignFirstResponder" attached to it here just in case
    [self.view removeFromSuperview];
}

in the MainViewController.h;

#import "SearchViewController.h"

@interface MainViewController <UIPopoverControllerDelegate>{
    SearchViewController *searcher;
}

in the MainViewController.m;

-(void)OpenSearch{

    static bool isSearchOpen = FALSE;

    //open up the subview for the search function. Open up as a mini view for the ipad and a full window view for the iphone.

    if (isSearchOpen == FALSE){

        isSearchOpen = TRUE;

        if (searcher == nil){

            searcher = [[SearchViewController alloc]init];

            searcher.delegate = self;

            if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){

                CGRect frame = searcher.view.frame;

                searcher.view.frame = CGRectMake(0, 0, frame.size.width, frame.size.height-88);

            }

        }

        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){

            //iphone

            [self addChildViewController:searcher];

            [self.view addSubview:searcher.view];

            [searcher didMoveToParentViewController:self];

        }else{

            //ipad

            popSearch = [[UIPopoverController alloc] initWithContentViewController:searcher];

            popSearch.popoverContentSize = searcher.view.frame.size;

            popSearch.delegate = self;

            [popSearch presentPopoverFromRect:CGRectMake(self.view.frame.size.width - 5,0, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

        }

    }else{

        isSearchOpen = FALSE;

        [self closeSearch];

    }    

}

-(void)closeSearch{

    //cancels the search and closes the search view

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){

        [searcher.view removeFromSuperview];

    }else{

        [popSearch dismissPopoverAnimated:YES];

    }

    isSearchOpen = FALSE;

}

Done :)

Different ways to differentiate between devices in iOS

There are many ways to figure out how to tell which device you are using, some are specific, some are general. They all serve their purpose. Here are some examples;

If you have a universal app and want to use a different nib for the ipad or iphone;

    NSString *nibName = [NSStringFromClass([self class]) stringByAppendingString:([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)? @"-iPhone" : @"-iPad"];

    self = [super initWithNibName:nibName bundle:nil];

* note be sure and name you nibs correctly.

If you have some specific code the you want to perform on either the iphone or ipad;

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){

    //iphone code

}else{

    //ipad code

}

If you want a quick definition change depending on if it is an ipad or iphone;

    int total = ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)? iPhone_Total :iPad_Total;

iOS Creating Custom Delegates in iOS6 with ARC

So you want two Objects to talk to each other more than a little bit? Here is what to do by example.  Lets say we have our MainViewController and a new SearchViewController that you want a delegate attached to it. This is all you need to do.

In SearchViewController.h

@protocol SearchViewDelegate <NSObject>

@optional

@required

-(void)didAskToSearch:(NSString*)string;

@end

@interface SearchViewController : UIViewController {

}

@property (nonatomic, assign) id <SearchViewDelegate> delegate;

@end

optional has non-required methods and required of course has required methods. 

In SearchViewController.m;

    [_delegate didAskToSearch: [self searchRequestDetails]];

this is put anywhere in the code when you want it to send the information back to the other object. 

In the MainViewController.h;

@interface MainViewController : UIViewController <SearchViewDelegate> {

}

In MainViewController.m;

SearchViewController *searcher = [[SearchViewController alloc]init];

searcher.delegate = self;

#pragma mark - SearchViewControllerDelegates

-(void)didAskToSearch:(NSString*)string{

     //do whatever you want with the string results

}

When creating the object, make sure the tell the delegate you have those methods. Then you just have to create the methods as per it is required.
