how to fetch contacts from iPhone using programmatically?

 Hi everyone,
This will help you to fetch contact information from your iOS Device Address book. First you have to include "AddressBookUI.framework" into your project and then you have to include "UINavigationControllerDelegate","ABPeoplePickerNavigationControllerDelegate" into header part of the controller. You have to also import "#import <AddressBookUI/AddressBookUI.h>" into current controller's header part.

#pragma mark -
#pragma mark Button Action Event
-(IBAction)callAddressbook:(id)sender
{
            ABPeoplePickerNavigationController *addressBookController = [[ABPeoplePickerNavigationController alloc]init];
            addressBookController.peoplePickerDelegate = self;
            addressBookController.delegate = self;
            addressBookController.navigationBar.tintColor = [UIColor blackColor];
            addressBookController.searchDisplayController.searchBar.tintColor = [UIColor blackColor];
            addressBookController.searchDisplayController.searchBar.backgroundColor = [UIColor blackColor];
            [self presentModalViewController:addressBookController animated:YES];
            [addressBookController release];
            addressBookController = nil;
}

#pragma mark -
#pragma mark ABPeoplePickerNavigationController Delegate Method

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker // called when address book closed
{
    [peoplePicker dismissModalViewControllerAnimated:YES];
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker  // called when select any contact from address book
      shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
  
    ABMultiValueRef addresses = [(NSMutableDictionary *)ABRecordCopyValue(person, kABPersonAddressProperty) autorelease];
    NSArray *addressesArray = [(NSArray *)ABMultiValueCopyArrayOfAllValues(addresses) autorelease];
    NSDictionary *dictAddress = [addressesArray objectAtIndex:0];
  
    ABMultiValueRef phone = [(NSMutableDictionary *)ABRecordCopyValue(person, kABPersonPhoneProperty) autorelease];
    NSArray *phoneArray = [(NSArray *)ABMultiValueCopyArrayOfAllValues(phone) autorelease];
    NSMutableString *strPhone = [NSMutableString string];
  
    for (int i=0; i<[phoneArray count]; i++)
    {
        [strPhone appendString:[NSString stringWithFormat:@"%@,",[phoneArray objectAtIndex:i]]];
    }
  
    [ApplicationData sharedInstance].selectedContact.contactId = (NSInteger) ABRecordGetRecordID(person);
    [ApplicationData sharedInstance].selectedContact.firstName = [(NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty) autorelease]==nil?@"":[(NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty)autorelease];
    [ApplicationData sharedInstance].selectedContact.lastName = [(NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty)autorelease]==nil?@"":[(NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty)autorelease];
    [ApplicationData sharedInstance].selectedContact.street = [dictAddress valueForKey:@"Street"]==nil?@"":[dictAddress valueForKey:@"Street"];
    [ApplicationData sharedInstance].selectedContact.telephone =  [strPhone stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@","]];
    [ApplicationData sharedInstance].selectedContact.city = [dictAddress valueForKey:@"City"]==nil?@"":[dictAddress valueForKey:@"City"];
    [ApplicationData sharedInstance].selectedContact.postcode = [dictAddress valueForKey:@"ZIP"]==nil?@"":[dictAddress valueForKey:@"ZIP"];
    [ApplicationData sharedInstance].selectedContact.state = [dictAddress valueForKey:@"State"]==nil?@"":[dictAddress valueForKey:@"State"];
    [ApplicationData sharedInstance].selectedContact.country = [dictAddress valueForKey:@"CountryCode"]==nil?@"":[dictAddress valueForKey:@"CountryCode"];
  
  
    [ApplicationData sharedInstance].obj_sendOrder.recipientName = [NSString stringWithFormat:@"%@ %@",[ApplicationData sharedInstance].selectedContact.firstName,[ApplicationData sharedInstance].selectedContact.lastName];
    [ApplicationData sharedInstance].obj_sendOrder.street = [ApplicationData sharedInstance].selectedContact.street;
    [ApplicationData sharedInstance].obj_sendOrder.city = [ApplicationData sharedInstance].selectedContact.city;
    [ApplicationData sharedInstance].obj_sendOrder.zip = [ApplicationData sharedInstance].selectedContact.postcode;
    [ApplicationData sharedInstance].obj_sendOrder.state = [ApplicationData sharedInstance].selectedContact.state;
    [ApplicationData sharedInstance].obj_sendOrder.country = [ApplicationData sharedInstance].selectedContact.country;
  
    [ApplicationData sharedInstance].obj_sendOrder.contactType = @"Phone";
  
    dictAddress = nil;
    addresses = nil;
    addressesArray = nil;
  
    phone = nil;
    phoneArray = nil;
    strPhone = nil;
  
    [peoplePicker dismissModalViewControllerAnimated:YES];
    return NO;
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker

                                property:(ABPropertyID)property
                              identifier:(ABMultiValueIdentifier)identifier // called to show detail of contact

AirPrint in iPhone SDK

Hi Everyone,
By using below code , you'll be able to print your view using AirPrint in iPhone SDK.

-(void)sendToPrinter
{

    NSString *filename = [appDelegate.pdfFilePath lastPathComponent];   
    filename = [filename stringByReplacingOccurrencesOfString:@".pdf" withString:@""];
    NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"pdf"];

    NSData *myData = [NSData dataWithContentsOfFile:path];
    UIPrintInteractionController *print = [UIPrintInteractionController sharedPrintController];

    print.delegate = self;
    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = [appDelegate.pdfFilePath lastPathComponent];
    printInfo.duplex = UIPrintInfoDuplexLongEdge;
    print.printInfo = printInfo;
    print.showsPageRange = YES;
    print.printingItem = myData;
    UIViewPrintFormatter *viewFormatter = [self.view viewPrintFormatter];
    viewFormatter.startPage = 0;
    print.printFormatter = viewFormatter;
   

    UIPrintInteractionCompletionHandler completionHandler = ^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) {};
   
    [print presentAnimated:YES completionHandler:completionHandler];
}

if you have query then send it to me. 

Thanks and Regards,

UIKeyborad Notification

Hi friends,
This informs you how to use UIKeyboardNotification into your project. By using this , you can make your custom animation at the time of keyboard appears/disappears.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardShow:)
                                                 name:UIKeyboardWillShowNotification
                                               object:nil];
   
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardHide:)
                                                 name:UIKeyboardWillHideNotification
                                               object:nil];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                               name:UIKeyboardWillShowNotification
                                               object:nil];
   
    [[NSNotificationCenter defaultCenter] removeObserver:self

                                                 name:UIKeyboardWillHideNotification
                                               object:nil];
}

- (void)keyboardShow:(NSNotification *)aNotification
{
    // the keyboard is showing so resize the table's height
    CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    NSTimeInterval animationDuration =
        [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
    CGRect frame = self.view.frame;
    frame.size.height -= keyboardRect.size.height;
    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
    [UIView setAnimationDuration:animationDuration];
    self.view.frame = frame;
    [UIView commitAnimations];
}

- (void)keyboardHide:(NSNotification *)aNotification
{
    // the keyboard is hiding reset the table's height
    CGRect keyboardRect = [[[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    NSTimeInterval animationDuration =
        [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
    CGRect frame = self.view.frame;
    frame.size.height += keyboardRect.size.height;
    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
    [UIView setAnimationDuration:animationDuration];
    self.view.frame = frame;
    [UIView commitAnimations];
}

If any one has query then place you it over here.

Image with Rounded Curve

static void addRoundedRectToPath(CGContextRef context, CGRect rect, float ovalWidth, float ovalHeight)
{
    float fw, fh;
    if (ovalWidth == 0 || ovalHeight == 0) {
        CGContextAddRect(context, rect);
        return;
    }
    CGContextSaveGState(context);
    CGContextTranslateCTM (context, CGRectGetMinX(rect), CGRectGetMinY(rect));
    CGContextScaleCTM (context, ovalWidth, ovalHeight);
    fw = CGRectGetWidth (rect) / ovalWidth;
    fh = CGRectGetHeight (rect) / ovalHeight;
    CGContextMoveToPoint(context, fw, fh/2);
    CGContextAddArcToPoint(context, fw, fh, fw/2, fh, 1);
    CGContextAddArcToPoint(context, 0, fh, 0, fh/2, 1);
    CGContextAddArcToPoint(context, 0, 0, fw/2, 0, 1);
    CGContextAddArcToPoint(context, fw, 0, fw, fh/2, 1);
    CGContextClosePath(context);
    CGContextRestoreGState(context);
}

-(UIImage *)getRoundCornerOfImage:(UIImage *)image
{
    int w = image.size.width;
    int h = image.size.height;
   
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    CGContextRef context = CGBitmapContextCreate(NULL, w, h, 8, 4 * w, colorSpace, kCGImageAlphaPremultipliedFirst);
   
    CGContextBeginPath(context);
    CGRect rect = CGRectMake(0, 0, image.size.width, image.size.height);
    addRoundedRectToPath(context, rect, 10, 10);
    CGContextClosePath(context);
    CGContextClip(context);
   
    CGContextDrawImage(context, CGRectMake(0, 0, w, h), image.CGImage);
   
    CGImageRef imageMasked = CGBitmapContextCreateImage(context);
    CGContextRelease(context);
    CGColorSpaceRelease(colorSpace);
    return [UIImage imageWithCGImage:imageMasked];
}

And Then just use like :
UIImage *Roundimage = [self getRoundCornerOfImage:originalImage];
