IOS - 获取联系电话用于地址簿-Java 学习之路

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授予，CFErrorRef错误）{
如果（授予）
[self loadContact];

}）;
}
else if（ABAddressBookGetAuthorizationStatus（）== kABAuthorizationStatusAuthorized）
{
[self loadContact];
}
}
其他
{
[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this link，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 <NSObject>
- (void) didLoadList:(NSNumber*) totalItems;
- (void) updateProgress:(NSNumber*) progress;
- (void) didComplete:(NSArray*) contactsImported;
@end

@property (nonatomic, assign) NSObject <ContactImporterProgressViewDelegate>* 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];
