大家知道在读取通讯录信息时需要引用AddressBook、AddressBookUI得框架，然后就可以进行相关操作。但是在iOS7中不能够像iOS6中直接读取通讯录信息，而是需要代码中取得用户授权才可以进行相关操作。
推荐使用如下方式：
CFErrorRef *error = nil;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we‘re on iOS 6
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
accessGranted = granted;
dispatch_semaphore_signal(sema);
});
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
}
else { // we‘re on iOS 5 or older
accessGranted = YES;
}
另外，网上还有一种版本if (accessGranted) {
NSMutableArray *addressBookTemp = [NSMutableArray array];
//ABAddressBookRef addressBooks = ABAddressBookCreate();
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
for (NSInteger i = 0; i < nPeople; i++)
{
TKAddressBook *addressBook = [[TKAddressBook alloc] init];
ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);
CFStringRef abName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
CFStringRef abLastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
CFStringRef abFullName = ABRecordCopyCompositeName(person);
}
...................................
}
// CFErrorRef *error = nil;
// ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
//
// __block BOOL accessGranted = NO;
//
// if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusNotDetermined){
// ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
//
// accessGranted=granted;
// });
//
// }
// else if (ABAddressBookGetAuthorizationStatus()==kABAuthorizationStatusAuthorized){
// accessGranted=YES;
// }
// else
// {
// NSLog(@"用户未授权提示");
// }
不推荐后者得原因是：经过测试（模拟器）后者取得用户授权后并不能立刻执行获取联系人等得相关操作，而前者可以顺利执行。
