方法总结:
在iOS9.0 之前,获取通讯录中的数据大多用的都是用基于C语言的有界面[AddressBookUI.framework]或者无UI界面[AddressBook.framework]类库,在OC开发中,可能会感觉到不爽! iOS9.0 之后,苹果进行了代码封装, 非常好用,下面我们一起来体验一下吧!
细节提醒:
有过这方面开发经验的小伙伴们可能知道,若要获取通讯录数据,必须要进行用户授权, 否则App是上线不成功的。
首先对比一下授权时的代码变化(这里就以有界面类库的为例):
- [AddressBookUI.framework] 实现
<pre>
ABAddressBookRef bookref = ABAddressBookCreateWithOptions(NULL, NULL);
//用户的授权
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
if (status == kABAuthorizationStatusNotDetermined) {
ABAddressBookRequestAccessWithCompletion(bookref, ^(bool granted, CFErrorRef error) {
if (error) {
NSLog(@"授权错误");
}
if (granted) {
NSLog(@"授权错误");
}
});
}
</pre>
- [ContactsUI/ContactsUI.h] 实现
<pre>
// 注意:别忘记导入头文件 <ContactsUI/ContactsUI.h>
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusNotDetermined) {
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (error) {
NSLog(@"授权失败");
}else {
NSLog(@"成功授权");
}
}];
}
</pre>
具体实现:
- [AddressBookUI.framework] 实现
- 创建控制器,并设置代理。
<pre>
ABPeoplePickerNavigationController *peosonVC = [[ABPeoplePickerNavigationController alloc] init];
peosonVC.peoplePickerDelegate = self;
[self presentViewController:peosonVC animated:YES completion:nil];
</pre>
- 获取个人数据为例 调用ABPeoplePickerNavigationController代理方法的实现:
<pre>
-
(void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person {
// 获取姓名
NSString *stringName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
NSString *secondedName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
NSLog(@"%@,%@",stringName,secondedName);// 获取电话号码
ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
CFIndex count = ABMultiValueGetCount(phones);
for (int i = 0; i < count; i++) {
CFStringRef label = ABMultiValueCopyLabelAtIndex(phones, i);
CFStringRef value = ABMultiValueCopyValueAtIndex(phones, i);
NSString *labelPhone = CFBridgingRelease(label);
NSString *valuePhone = CFBridgingRelease(value);
NSLog(@"%@,%@",labelPhone,valuePhone);
}
}
</pre>
- <ContactsUI/ContactsUI.h> 实现
- 创建控制器,并设置代理
<pre>
CNContactPickerViewController *pickerVC = [[CNContactPickerViewController alloc] init];
pickerVC.delegate = self;
[self presentViewController:pickerVC animated:YES completion:nil];
</pre>
- 创建控制器,并设置代理获取个人数据为例 调用ABPeoplePickerNavigationController代理方法的实现
<pre>
// 当选择一个联系人的时候调用
-(void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact{
NSLog(@"%@",contact.givenName);
NSLog(@"%@",contact.phoneNumbers);
for (CNLabeledValue *labelValue in contact.phoneNumbers) {
CNPhoneNumber *number = labelValue.value;
NSLog(@"%@",number.stringValue);
}
}
</pre>
对比总结:
从上面可以看出,新方法在用户授授权方面,没有太大的简化,但在代理方法获取用户的数据中,却简化了不少,获取用户数据也非常方便。
