Display all contacts from the iOS device in custom table viewcontoller when contacts button is clicked rather than default view of the device

Question

In my app I need to display all contacts from the device in a custom table viewcontoller when I click contacts button. I found a lot of demos using addressbook framework but in it the contacts are displayed in default device format using ABPeoplePickerNavigationController. But I need to display all contacts in custom view. Is there any way to do that. Also my app should work in iOS7 and above. Can Contacts Framework be used in iOS 7 and 8? I'm using xcode 7.2. Please provide the solutions in objective C as I'm not familier with swift.Thanks in advance.

Answer 1

In iOS 9 AddressBook Framework is deprecated.Kindly use Contact framework.

I tried, and it works fabulously.

Very Perfect answer is below.

#import "ViewController.h"
#import <Contacts/Contacts.h>
@interface ViewController ()<UITableViewDataSource,UITableViewDelegate>
{
   UITableView *tableViewContactData;
   NSMutableArray *arrayTableData;
}

@end

@implementation ViewController

- (void)viewDidLoad 
{
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.

  arrayTableData = [[NSMutableArray alloc]init];
  [self fetchContactsandAuthorization];
  tableViewContactData = [[UITableView alloc] init];
  tableViewContactData.frame = CGRectMake(0, 50, 320, 518);
  tableViewContactData.delegate = self;
  tableViewContactData.dataSource = self;
  [tableViewContactData registerClass:[UITableViewCell class] forCellReuseIdentifier:@"cell"];
  [self.view addSubview:tableViewContactData];
}

- (void)didReceiveMemoryWarning {
  [super didReceiveMemoryWarning];
   // Dispose of any resources that can be recreated.
}

//UITAbleView Deleate methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
  return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   return  arrayTableData.count;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  static  NSString *strCell = @"cell";
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:strCell];
  if(cell==nil)
  {
    cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strCell];
  }
  cell.textLabel.text = arrayTableData[indexPath.row];
  return cell;
}

//This is for fetching contacts from iPhone.Also It asks authorization permission.
-(void)fetchContactsandAuthorization
{
   // Request authorization to Contacts
   CNContactStore *store = [[CNContactStore alloc] init];
   [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
   if (granted == YES)
   {
      //keys with fetching properties
      NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
      NSString *containerId = store.defaultContainerIdentifier;
      NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
      NSError *error;
      NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
      if (error) 
      {
         NSLog(@"error fetching contacts %@", error);
      } 
      else 
      {
            NSString *phone;
            NSString *fullName;
            NSString *firstName;
            NSString *lastName;
            UIImage *profileImage;
            NSMutableArray *contactNumbersArray = [[NSMutableArray alloc]init];
            for (CNContact *contact in cnContacts) {
                // copy data to my custom Contacts class.
                firstName = contact.givenName;
                lastName = contact.familyName;
                if (lastName == nil) {
                    fullName=[NSString stringWithFormat:@"%@",firstName];
                }else if (firstName == nil){
                    fullName=[NSString stringWithFormat:@"%@",lastName];
                }
                else{
                    fullName=[NSString stringWithFormat:@"%@ %@",firstName,lastName];
                }
                UIImage *image = [UIImage imageWithData:contact.imageData];
                if (image != nil) {
                    profileImage = image;
                }else{
                    profileImage = [UIImage imageNamed:@"person-icon.png"];
                }
                for (CNLabeledValue *label in contact.phoneNumbers) {
                    phone = [label.value stringValue];
                    if ([phone length] > 0) {
                        [contactNumbersArray addObject:phone];
                    }
                }
                NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,@"fullName",profileImage,@"userImage",phone,@"PhoneNumbers", nil];
                [arrayTableData addObject:[NSString stringWithFormat:@"%@",[personDict objectForKey:@"fullName"]]];
                NSLog(@"The contactsArray are - %@",arrayTableData);
            }
            dispatch_async(dispatch_get_main_queue(), ^{
                [tableViewContactData reloadData];
            });
        }
    }
}];
}
@end

The output is

The contactsArray are - (
"John Appleseed",
"Kate Bell",
"Anna Haro",
"Daniel Higgins",
"David Taylor",
"Hank Zakroff"
}
