UIAddressBook in UITableView with NSObjectClass - ios

Question

I need to make a UITableView which fetches address book contents in it and also a UISearchBar which searches the address book contents.
I need an implementation like this project
http://www.appcoda.com/search-bar-tutorial-ios7/
But the problem is here the data is static and I want to load address book's data in it.

I have created ContactData NSObject Class. In following method, I am creating its object for each contact. At the end, you will get NSMutableArray named contactArr.
-(void)loadContacts{
ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
//NSLog(#"%#", addressBook);
});
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
CFErrorRef *error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBook);
for(int i = 0; i < numberOfPeople; i++) {
ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );
NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));
NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));
ContactData *dataObj = [[ContactData alloc]init];
NSString *Name = #" ";
if ([firstName length]>0) {
if ([lastName length]>0) {
Name = [NSString stringWithFormat:#"%# %#",firstName,lastName];
}
else{
Name = firstName;
}
}
else{
Name = #" ";
}
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
[[UIDevice currentDevice] name];
//NSLog(#"\n%#\n", [[UIDevice currentDevice] name]);
NSString *phoneNumber = #" ";
for (CFIndex i = 0; i < ABMultiValueGetCount(phoneNumbers); i++) {
phoneNumber = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(phoneNumbers, i);
}
ABMultiValueRef Emails = ABRecordCopyValue(person, kABPersonEmailProperty);
[[UIDevice currentDevice] name];
NSString *Email; //= #" ";
for (CFIndex i = 0; i < ABMultiValueGetCount(Emails); i++) {
Email = (__bridge_transfer NSString *) ABMultiValueCopyValueAtIndex(Emails, i);
}
ABMultiValueRef Addresses = ABRecordCopyValue(person, kABPersonAddressProperty);
NSString *address = #" ";
NSMutableDictionary* addressDict = [[NSMutableDictionary alloc]init];
for (CFIndex i = 0; i < ABMultiValueGetCount(Addresses); i++) {
addressDict = (__bridge_transfer NSMutableDictionary *) ABMultiValueCopyValueAtIndex(Addresses, i);
//NSLog(#"address = %#", addressDict);
NSString * street = [addressDict objectForKey:#"Street"];
NSString * city = [addressDict objectForKey:#"City"];
NSString * state = [addressDict objectForKey:#"State"];
NSString *country = [addressDict objectForKey:#"Country"];
if (country.length>0 || state.length>0 || city.length>0 || street.length>0) {
if (country.length>0 && state.length>0) {
address = [NSString stringWithFormat:#"%#, %#", state,country];
}
else if(country.length>0 && city.length>0){
address = [NSString stringWithFormat:#"%#, %#", city,country];
}
else if (state.length>0 && street.length>0){
address = [NSString stringWithFormat:#"%#, %#", street,country];
}
else if (state.length>0 && city.length>0){
address = [NSString stringWithFormat:#"%#, %#", city,state];
}
else if (state.length>0 && street.length>0){
address = [NSString stringWithFormat:#"%#, %#", street,state];
}
else if (city.length>0 && street.length>0){
address = [NSString stringWithFormat:#"%#, %#", street,city];
}
else if (country.length>0){
address = country;
}
else if (state.length>0){
address = state;
}
else if (city.length>0){
address = city;
}
}
else{
address = #" ";
}
}
//NSLog(#"address = %#", address);
NSData *imgData = (__bridge_transfer NSData *) ABPersonCopyImageDataWithFormat(person, kABPersonImageFormatThumbnail);
dataObj.name = Name;
dataObj.email = Email;
dataObj.phone = phoneNumber;
dataObj.imageData = imgData;
dataObj.address = address;
[contactArr addObject:dataObj];
}
NSLog(#"contacts loaded");
//NSLog(#"count = %lu", (unsigned long)contactArr.count);
}
else {
//Go to settings and allow access to use contacts[GlobalFunction removeWaitView];
}
}

First make sure you have the correct frameworks imported:
#import <AddressBook/AddressBook.h>
Fetch the contacts of AddressBook like this:
ABAddressBookRef addressBook = ABAddressBookCreate( );
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople( addressBook );
CFIndex nPeople = ABAddressBookGetPersonCount( addressBook );
for ( int i = 0; i < nPeople; i++ )
{
ABRecordRef ref = CFArrayGetValueAtIndex( allPeople, i );
//further code
}
Then populate the UITableView as usual (as per the example you already provided).
Thankfully this framework is being deprecated. The new Contacts API in iOS 9 is gorgeous.
