简单的对于通讯录获得的总结，不成敬意！
1.用的类库，导入的头文件
iOS9之前
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
遵循
ABPeoplePickerNavigationControllerDelegate
iOS9之后
#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>
遵循
CNContactPickerDelegate
2.仅仅读取(相当于调用系统的类和界面（类似获取照片的功能）)
(1)是否授权方面：(示例代码)
iOS9之前
if (IOS_BEFORE(9.0)) {
WS(ws);
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
if (status ==kABAuthorizationStatusAuthorized) {// 授权成功
ABPeoplePickerNavigationController *peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
peoplePicker.peoplePickerDelegate = self;
// iOS8之后要加入这个属性
if (IOS_LATER(8.0)) {
peoplePicker.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
}
[self presentViewController:peoplePicker animated:YES completion:nil];
}else {// 授权失败
// 获取通讯录不是在主线程中获得，所以切换主线程，展示错误
dispatch_async(dispatch_get_main_queue(), ^{
[ws antuorFaildToShowView];
});
NSLog(@"授权失败");
}
}
iOS9之后
else {
CNContactStore *contactStore = [[CNContactStore alloc] init];
WS(ws);
[contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
CNContactPickerViewController *picker = [[CNContactPickerViewController alloc] init];
picker.delegate = self;
[self presentViewController:picker animated:YES completion:^{}];
}else {
NSLog(@"授权失败");
NSLog(@"[NSThread currentThread] = %@",[NSThread currentThread]) ;
// 获取通讯录不是在主线程中获得，所以切换主线程，展示错误
dispatch_async(dispatch_get_main_queue(), ^{
[ws antuorFaildToShowView];
});
}
}];
}
(2)代理方法示例：(示例代码)
iOS9之前
#pragma mark - ABPeoplePickerNavigationControllerDelegate
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
ABMultiValueRef valuesRef = ABRecordCopyValue(person, kABPersonPhoneProperty);
CFIndex index = ABMultiValueGetIndexForIdentifier(valuesRef,identifier);
CFStringRef value = ABMultiValueCopyValueAtIndex(valuesRef,index);
NSString *phoneNumber = (__bridge NSString*)value;
NSString *newPhone =[self trimSting:phoneNumber];
//赋值给我TextFeild
[self saveTeleToLoca:newPhone];
[self dismissViewControllerAnimated:YES completion:^{}];
}
-(void)saveTeleToLoca:(NSString *)phone {
_phoneTF.text =phone;
[CMUserDefaults saveLocalString:phone andKey:kPhoneRechargeTelePhone];
}
- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker {
[self dismissViewControllerAnimated:YES completion:nil];
}
iOS9之后
#pragma mark - CNContactPickerDelegate
#ifdef __IPHONE_9_0
// 通讯录列表 - 点击某个联系人 - 详情页 - 点击一个号码, 返回
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty {
// 获得到用户的手机号码
NSString *phoneNumber = [contactProperty.value stringValue];
// 去掉手机号码的“-”
NSString *newPhone =[self trimSting:phoneNumber];
//赋值给我TextFeild
[self saveTeleToLoca:newPhone];
}
- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker {
[self dismissViewControllerAnimated:YES completion:nil];
}
#endif
注意：
1.iOS10之后要在info.plist 中加入以下的属性（来询问获得用户的权限）
<key>NSContactsUsageDescription</key>
<string>contactsDesciption</string>
具体iOS10之后相册和麦克风都要征得用户权限的key详见：http://www.jianshu.com/p/c212cde86877
2.对于为了防止iOS9的系统运行出现iOS10的程序防止编译错误，无法通过，应该用条件编译如下：
#if __IPHONE_9_0
// 9.0之后的用，防止9.0之前的编译失败
#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>
@interface PhoneRechargeViewController ()<UITextFieldDelegate,CNContactPickerDelegate,NHThirdPayViewDelegate,ABPeoplePickerNavigationControllerDelegate>
#else
@interface PhoneRechargeViewController ()<UITextFieldDelegate,ABPeoplePickerNavigationControllerDelegate,NHThirdPayViewDelegate>
#endif
3.需要获得通讯录具体数据用：（相当于获得通讯录数据，自己展示）
