Is possible to open Contacts app from my app iOS 7

Question

I wanted to know if it was possible to open the contacts app from my app iOS 7. I'll explain,I would like to give the user the option of searching through contacts and then clicking on the contact to be redirected to contacts app with the specific page for the selected contact Is possible? And is possible also do this with reminders and calendar events?

Answer 1

It is possible, here is an example:

.h file:

@interface PickViewController : UIViewController <ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate>
@property (strong, nonatomic) ABPeoplePickerNavigationController *peoplePicker;
@end

.m file:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    _peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
    _peoplePicker.delegate = self;
}

- (IBAction)btnAdd:(id)sender
{
    [self presentViewController:self.peoplePicker animated:YES completion:nil];
}

#pragma mark - ABPeoplePickerNavigationController Delegate

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
    [self dismissViewControllerAnimated:YES completion:NULL];
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
    NSString* name = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSLog(@"Name %@", name);
    return NO;
}

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
    return YES;
}

• Add AddressBook Frame work.

  import AddressBook/AddressBook.h

Then I have a working example: You have to change the code in accordance to your requirements:

-(void)loadContact
{
    dispatch_async(dispatch_get_main_queue(), ^(void){
        if (loadingView == nil) {
            loadingView = [LoadingView loadingViewInSuperView:self.view];
        }
    });
ABAddressBookRef ab;
ab = ABAddressBookCreate();


int len = (int) ABAddressBookGetPersonCount(ab);
NSMutableArray *allPeople = (__bridge NSMutableArray *)ABAddressBookCopyArrayOfAllPeople(ab);
int i;
for(i = 0; i < len ; i++)
{

    // Initialize the dictionary
    NSMutableDictionary *dictAddress = [[NSMutableDictionary alloc] init];
    ABRecordRef person = (__bridge ABRecordRef)([allPeople objectAtIndex:i]);

    [dictAddress setValue:@"0" forKey:@"sel"];

    [dictAddress setValue:@"" forKey:@"FirstName"];
    [dictAddress setValue:@"" forKey:@"LastName"];
    [dictAddress setValue:@"" forKey:@"Name"];

    [dictAddress setValue:@"" forKey:@"PhoneMobile"];
    [dictAddress setValue:@"" forKey:@"PhoneHome"];
    [dictAddress setValue:@"" forKey:@"PhoneWork"];

    [dictAddress setValue:@"" forKey:@"CompanyName"];

    [dictAddress setValue:@"" forKey:@"AddressCity"];
    [dictAddress setValue:@"" forKey:@"AddressCountry"];
    [dictAddress setValue:@"" forKey:@"AddressState"];
    [dictAddress setValue:@"" forKey:@"AddressCountryCode"];
    [dictAddress setValue:@"" forKey:@"AddressStreet"];
    [dictAddress setValue:@"" forKey:@"AddressZipCode"];

    [dictAddress setValue:@"" forKey:@"EmailWork"];
    [dictAddress setValue:@"" forKey:@"EmailHome"];
