How to add UINavigationController to UITabbarController Programatically?


Today I am going to Explain you How to Add UINavigation Controller to UITabbarController.

  • When you add UIViewController to UIWindow Your Application become ViewControllerBase(SingleView) Application.
  • When you add UIViewController to UINavigationController your application become NavigationBased(Master-Detail) Application.
  • When you add UIViewController/UINavigationController to your UITabbarController Your application become Tabbased Application.

so here we are using the same concept that add your Navigation Controller to UITabbarController so you will get Push/Pop effect in UITabbar Controller.

//Initialize tabbar Controller and All Navigation Controllers are added into Tabbar Controller
self.tabbar = [[UITabBarController alloc] init];
NSArray *arrNVControllers = [NSArray arrayWithObjects:nav1,nav2,nav3,nav4, nil];

self.tabbar.viewControllers = arrNVControllers;

Perform Lazy Loading with Image Cache(HJCache)


I am going to explain you how to perform lazy loading with Image Cache using HJCache.It will cache your images according to your requirements. I have perform caching for 1 week.Now i am showing you the steps for achieving you task very simple way.

Step 1:Drag and Drop HJcache Classes into your Project(I have already Provided)

step 2: In Application Delegate Import “HJObjManager.h” file and Make an Object of It.

Step 3:In Application Delegate.m file @synthesize the Object write the following code for Image caching.

Step 4: Now import “HJManagedImageV.h” where you want to implement the lazy loading.

Step 5. Make the custom cell and Take UIView instead of UIImageview in your Custom cell and inherit  Class “HJManagedImageV” as shown here.

Step 6: In use the Object of HJManagedImageV and provide the URL from your Array/Dictionary other things are managed by HJcache Object it self.

Now your task is getting completed.You can have the complete code by Clicking Here

NSXML Parsing with Rest api and Mapview with Annotation?


Today I am going to explain you How to perform Parsing with NSXML and How to show annotation in MKMapView.

Here I am Taking 1 UITextField and 1 UIButton.Whatever city name you will enter in the Textfield and Press Button it will show you in MKMapView with Annotation.

Step 1: Add Frameworks



step 2: Add Files

1.Place.h and Place.m

2.PlaceMark.h and PlaceMark.m (I will Provide).

step 3: Import Files in your view controller’s header file  and Declare Variables as shown in the Screenshots.

step 4: @synthesize all Variables as shown.

Step 5: Take NSString with Rest api and provide the textfield value to it.Make the connection with URL Request as shown.

NSString *strUrl = [NSString stringWithFormat:@””,self.txtSearch.text];
NSURLConnection *conn = [NSURLConnection connectionWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:strUrl]] delegate:self];

check the connection object

if(conn) = [[NSMutableData data] init];

Step 6:Implement all the connection Methods as shown.

#pragma mark – Connection Delegates Methods

– (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
NSLog(@”Error ==>%@”,error);

– (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{


– (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
[ appendData:data];

– (void)connectionDidFinishLoading:(NSURLConnection *)connection{
//Standard NSXMLParser – SAX Parser
NSXMLParser *parser = [[NSXMLParser alloc]];
[parser parse];
Step 7:Now Implement Parsing Methods with Root Tag and Object Tag so it will give’s you all the tags.

#pragma mark – NSXML Parsing Delegates Methods

// Document handling methods
// sent when the parser begins parsing of the document.
– (void)parserDidStartDocument:(NSXMLParser *)parser{

// sent when the parser finds an element start tag.
– (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
if([elementName isEqualToString:@”GeocodeResponse“])
self.arrResult = [NSMutableArray array];
else if ([elementName isEqualToString:@”result“])
self.dMain = [NSMutableDictionary dictionary];
– (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

// sent when an end tag is encountered. The various parameters are supplied as above.
// sent when the parser has completed parsing. If this is encountered, the parse was successful.
– (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
if([elementName isEqualToString:@”GeocodeResponse“]){

}else if ([elementName isEqualToString:@”result“])
[self.arrResult addObject:self.dMain];
}else {
[self.dMain setObject:self.strings forKey:elementName];

Step 7:In parserDidEndDocument method you will get all the value whatever you required.Here I am getting Latitude/Longitude and Address as shown.

=> Make the object of Place class and Provide the parameter also make the object of PlaceMark and Provide the object of place class and Add the Placemark object to MapView as an Annotation.

– (void)parserDidEndDocument:(NSXMLParser *)parser{
NSLog(@”Array = %@”,self.arrResult);

float latitude= [[[self.arrResult objectAtIndex:0] valueForKey:@”lat”] floatValue];
float longitude=[[[self.arrResult objectAtIndex:0] valueForKey:@”lng”] floatValue];

Place* home = [[Place alloc] init]; = [[self.arrResult objectAtIndex:0] valueForKey:@”formatted_address”];
home.latitude = latitude;
home.longitude = longitude;

PlaceMark *from = [[PlaceMark alloc] initWithPlace:home];
[self.mView addAnnotation:from];
[self centerMap];

Step 8:For Annotation here you have to Integrate MKMapView’s Annotation Delegate methods as shown.

#pragma mark – MapView Annotation

– (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
// if it’s the user location, just return nil.
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;

// try to dequeue an existing pin view first
static NSString* AnnotationIdentifier = @”AnnotationIdentifier”;
MKPinAnnotationView* pinView = [[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
return pinView;

How to use Socialize in your iPhone/iPad native application?


I have integrate Socialize in one of my sample code and believe me it’s’s far better than any other sharing media.just visit this web site initially.

It includes Email,Facebook and Twitter.I have Integrated Email and Twitter and working on Facebook as well.I am going to Explain you how to integrate it in your application.

Step 1: Click Here

Step 2: Choose 1 st option  Register and get your API keys.Once you have your API Key’s with you then follow step 3.

Step 3: When you click on DownLoad SDK for iOS you will get Framework for Integration.

Step 4: Add Socialize framework to your Application with Copy option selected as shown in the image.

step 5:Add Required Framework as shown below.


step 6: Set other Linker Flag as shown below.

step 7: Import Header and Set up your Socialize Keys like this.

//import the socialize header
#import <Socialize/Socialize.h>

#pragma mark
- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
    // set the socialize api key and secret, register your app here:
    [Socialize storeConsumerKey:@"SOCIALIZE_CONSUMER_KEY"];
    [Socialize storeConsumerSecret:@"SOCIALIZE_CONSUMER_SECRET"];

    //your application specific code

    return YES;

Step 8: Include Socialize in your App!

// Header file

// Store the action bar in a property on your view controller

#import <Socialize/Socialize.h>

@interface CreateActionBarViewController : UIViewController
@property (nonatomic, retain) SocializeActionBar *actionBar;
// Implementation file

// Instantiate the action bar in your view controller

- (void)viewDidLoad
    [super viewDidLoad];

    if (self.actionBar == nil) {
        self.actionBar = [SocializeActionBar actionBarWithKey:@"" name:@"Something" presentModalInController:self];
        [self.view addSubview:self.actionBar.view];

Now your App is ready to display Socialize bar.Here I am giving you the Sample code with Twitter integration and update it once it get completed with Facebook as well.

Custom Calender For iPad


I have implemented Custom Calender Control for iPad which is bit simple to implement.

Step 1: Add the Listed File into your Project.(I have Provided  all Listed Files.)






Step 2: Now your 70% Task is completed.You need to Integrate the Delegate Methods only.

#pragma mark – CalendarViewDelegate methods
-(void)monthChanged:(CFGregorianDate)currentMonth viewLeftTop:(CGPoint)viewLeftTop height:(float)height{


-(void)beforeMonthChange:(TdCalendarView *)calendarView willto:(CFGregorianDate)currentMonth{

Here i am attaching the sample code for the same.

iOS5 – how to turn off ARC on individual files ?

iOS5 SDK comes with new feature of ARC.

ARC = Automatic Reference Counting which is used for enabling memory management at compiler level.


But due to this feature, you might not able to compile facebook API, HJCache library or any other libraries developed for iPhone/iPad development.

Here is the one of the example of that error.

Automatic Reference Counting forbids explicit message send of ‘dealloc’

I have shared a trick to enable older library compilation in new iOS5 SDK.

  1. Click on the Project.
  2. Click on the target.
  3. Select build phases tab.
  4. Select the multiple files in which you want to turn off ARC.
  5. Press ENTER / Hit Enter key
  6. Type “-fno-objc-arc” ( without quotes, as shown in image )
I hope this might be helpful to you.
Please let me know your comments for this.
Thanks & Regards,
