IOS – 获取联系电话用于地址簿

我有一台设备手机运行ios 6.0.1，我希望在我的设备中获得所有联系人。 我尝试将iphone用于IOS 5.1,6.1.3并且它的工作正常。 不幸的是，当它运行ios 6.0.1时，数据为空

这是我的代码：

if（[[[[UIDevice currentDevice] systemVersion] floatValue]> 5.2）{

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL); if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) { ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) { if (granted) [self loadContact]; }); } else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) { [self loadContact]; } } else { [self loadContact]; } 

– （void）loadContact {

 ABAddressBookRef addressBooks = ABAddressBookCreate(); allPeople = (__bridge NSArray *)(ABAddressBookCopyArrayOfAllPeople(addressBooks)); peopleCount = ABAddressBookGetPersonCount(addressBooks); } 

我不知道，为什么它不适用于ios 6.0.1

我找到了这个链接 ，并且这样做，但我的设备没有数据。

你能帮我解决这个问题吗？

您的代码中最大的问题是您需要将引用“addressBookRef”传递给“loadContact”方法。 “ABAddressBookCreate”不适用于iOS6 – 您需要使用ABAddressBookRequestAccessWithCompletion创建的那个。

顺便说一句。 而不是检查iOS版本更好地使用它来确定您是否需要请求权限。 这是我正在使用的代码 – 随意使用它：

 -(BOOL)isABAddressBookCreateWithOptionsAvailable { return &ABAddressBookCreateWithOptions != NULL; } - (void) importContactsFromAddressBook { ABAddressBookRef addressBook; if ([self isABAddressBookCreateWithOptionsAvailable]) { CFErrorRef error = nil; addressBook = ABAddressBookCreateWithOptions(NULL,&error); ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { // callback can occur in background, address book must be accessed on thread it was created on if (error) { [self.delegate addressBookHelperError:self]; } else if (!granted) { [self.delegate addressBookHelperDeniedAcess:self]; AddressBookUpdated(addressBook, nil, self); } else { // access granted AddressBookUpdated(addressBook, nil, self); CFRelease(addressBook); } }); } else { // iOS 4/5 addressBook = ABAddressBookCreate(); AddressBookUpdated(addressBook, NULL, self); CFRelease(addressBook); } } void AddressBookUpdated(ABAddressBookRef addressBook, CFDictionaryRef info, void *context) { NSMutableArray* addressBookContacts = [NSMutableArray array]; //import from address book CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople( addressBook ); CFIndex nPeople = ABAddressBookGetPersonCount( addressBook ); [helper.delegate performSelectorOnMainThread:@selector(didLoadList:) withObject:[NSNumber numberWithInt:nPeople] waitUntilDone:YES]; if(allPeople) CFRelease(allPeople); [helper.delegate performSelectorOnMainThread:@selector(didComplete:) withObject:addressBookContacts waitUntilDone:YES]; } 

我将这些函数封装到类中，委托是：

 @protocol ContactImporterProgressViewDelegate  - (void) didLoadList:(NSNumber*) totalItems; - (void) updateProgress:(NSNumber*) progress; - (void) didComplete:(NSArray*) contactsImported; @end @property (nonatomic, assign) NSObject * delegate; 

要使用它，我建议在另一个线程上调用它来阻止UI并显示进度（当你有5000个条目时需要一段时间）：

 ContactImporter* importer = [[ContactImporter alloc] init]; importer.delegate = self; NSOperationQueue *queue = [[[NSOperationQueue alloc] init] autorelease]; NSInvocationOperation *oper = [[[NSInvocationOperation alloc] initWithTarget:importer selector:@selector(importContactsFromAddressBook) object:nil] autorelease]; [queue addOperation:oper]; [importer release];
