OC通讯录选择封装

ContactsService.h代码

//block返回选中的通讯里名字和电话
typedef void(^ChoseContacts)(NSString *name,NSString *phone);
@interface ContactsService : NSObject
@property(nonatomic,copy)ChoseContacts contacts;
/*
 单例
 */
+(ContactsService *)sharedContactsService;
/**

 */
-(void)showContactsServiceWithVC:(UIViewController *)nav;

@end

ContactsService.m代码

#import "ContactsService.h"
#import <ContactsUI/ContactsUI.h>
@interface ContactsService ()<CNContactPickerDelegate>
{
    CNContactPickerViewController *_contactPickerViewController;
}
@end

@implementation ContactsService

    return contacts;
}

-(void)showContactsServiceWithVC:(UIViewController *)nav{
    _contactPickerViewController = [[CNContactPickerViewController alloc] init];
    _contactPickerViewController.delegate = self;

    [nav presentViewController:_contactPickerViewController animated:YES completion:nil];
}

// 如果实现该方法当选中联系人时就不会再出现联系人详情界面， 如果需要看到联系人详情界面只能不实现这个方法，
#pragma mark CNContactPickerDelegate
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact {
    [self printContactInfo:contact];
    [_contactPickerViewController dismissViewControllerAnimated:YES completion:nil];
}
- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker{

}

- (void)printContactInfo:(CNContact *)contact {
    NSString *givenName = contact.givenName;
    NSString *familyName = contact.familyName;
    //NSLog(@"givenName=%@, familyName=%@", givenName, familyName);
    NSArray * phoneNumbers = contact.phoneNumbers;
    for (CNLabeledValue<CNPhoneNumber*>*phone in phoneNumbers) {
       // NSString *label = phone.label;
        CNPhoneNumber *phonNumber = (CNPhoneNumber *)phone.value;
       // NSLog(@"label=%@, value=%@", label, phonNumber.stringValue);
        if(self.contacts){
            self.contacts([NSString stringWithFormat:@"%@%@",familyName,givenName], phonNumber.stringValue);
        }
        break;
    }
}
@end

使用：

 ContactsService *contacts = [ContactsService sharedContactsService];
    contacts.contacts = ^(NSString *name, NSString *phone) {
        NSString *str = [NSString stringWithFormat:@"选中的名字：%@  电话：%@",name,phone];
        UIAlertView *aler = [[UIAlertView alloc]initWithTitle:@"通讯里" message:str delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [aler show];
    };
    [contacts showContactsServiceWithVC:self];
