电话号码变成这样。电话ABMultiValueRef 0x17674380，带1个值0:$$（0x176740e0）-7124779070（0x176742a0）
如何从上面的行中获得此数字"7124779070"。
我正在为ios 7使用此代码。它是正确的还是错误的，请告诉我。
int i;
ABAddressBookRef contactBook = ABAddressBookCreateWithOptions(NULL, NULL);
NSMutableArray *allData = ( NSMutableArray *)(ABAddressBookCopyArrayOfAllPeople(contactBook));
CFIndex contactNum = CFArrayGetCount((__bridge CFArrayRef)(allData));
for (i = 0; i < contactNum; i++)
{
ABRecordRef ref = CFArrayGetValueAtIndex((__bridge CFMutableArrayRef)(allData), i);
NSString* firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
NSString* lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
NSString* phonesNum = ABRecordCopyValue(ref, kABPersonPhoneProperty);
// Remove all formatting symbols that might be in both phone number being compared
NSCharacterSet *toExclude = [NSCharacterSet characterSetWithCharactersInString:@"/.()- "];
phonesNum = [[phonesNum componentsSeparatedByCharactersInSet:toExclude] componentsJoinedByString: @""];
NSString *phoneNumber = [[phonesNum componentsSeparatedByCharactersInSet:toExclude] componentsJoinedByString: @""];
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
if (firstName!=nil)
{
[dic setObject:(__bridge id)(firstName) forKey:@"firstName"];
}
if (lastName !=nil) {
[dic setObject:(__bridge id)(lastName) forKey:@"lastName"];
}
if (phonesNum!=nil) {
[dic setObject:(__bridge id)(phonesNum) forKey:@"phonesNum"];
}
[arr_Contacts addObject:dic];
NSLog(@"First name %@", firstName);
NSLog(@"Last Name %@", lastName);
NSLog(@"Phone %@", phonesNum);
}
首先，请求权限：
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
if (status != kABAuthorizationStatusAuthorized && status != kABAuthorizationStatusNotDetermined) {
// tell user to enable contacts in privacy settings
NSLog(@"You previously denied access: You must enable access to contacts in settings");
return;
}
CFErrorRef error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);
if (!addressBook) {
NSLog(@"ABAddressBookCreateWithOptions error: %@", CFBridgingRelease(error));
return;
}
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
if (error) {
NSLog(@"ABAddressBookRequestAccessWithCompletion error: %@", CFBridgingRelease(error));
}
if (granted) {
[self getContacts:addressBook];
} else {
// tell user to enable contacts in privacy settings
NSLog(@"You just denied access: You must enable access to contacts in settings");
}
CFRelease(addressBook);
});
其次，要检索电话号码，请使用ABMultiValueCopyValueAtIndex:
- (void)getContacts:(ABAddressBookRef)addressBook
{
NSArray *allData = CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));
NSInteger contactCount = [allData count];
for (int i = 0; i < contactCount; i++) {
ABRecordRef person = CFArrayGetValueAtIndex((__bridge CFArrayRef)allData, i);
NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
NSString *lastName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
if (firstName) {
dictionary[@"firstName"] = firstName;
}
if (lastName) {
dictionary[@"lastName"] = lastName;
}
ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
CFIndex phoneNumberCount = ABMultiValueGetCount(phones);
if (phoneNumberCount > 0) {
NSString *phone = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phones, 0));
dictionary[@"phone"] = phone;
}
// or if you wanted to iterate through all of them, you could do something like:
//
// for (int j = 0; j < phoneNumberCount; j++) {
// NSString *phone = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phones, j));
//
// // do something with `phone`
// }
if (phones) {
CFRelease(phones);
}
[arr_Contacts addObject:dictionary];
}
}
上面提到的几个附加问题：
ABAddressBookCreateWithOptions不返回可变数组。它是一个不可变的数组。将所有这些可变引用替换为不可变引用。您必须遵守创建规则，即您负责释放从名称为
Create或Copy的Core Foundation方法返回的任何对象。如果对象支持免费桥接（例如联系人数组、名字字符串、姓氏字符串等），则可以使用CFBridgingRelease或__bridge_transfer将所有权转移到ARC。如果对象不支持免费桥接（例如上面的phones或addressBook对象），则必须为有问题的对象显式调用CFRelease。请确保通过静态分析器运行代码（shift+命令+B，或者从Xcode的"产品"菜单中选择"分析"），它会为您确定这类问题。
如果一个函数，比如
ABAddressBookCreateWithOptions提供了一个错误参数，你应该利用它。我在上面说明了CFErrorRef对象的正确使用。
您在控制台中从Phone%@NSLog收到了什么？如果电话ABMultiValueRef 0x17674380有1个值0:$！！$（0x176740e0）-7124779070（0x176742a0）仅在"-"之后的子字符串
NSString *myString = @"Phone ABMultiValueRef 0x17674380 with 1 value(s) 0: $!!$ (0x176740e0) - 7124779070 (0x176742a0)";
NSArray *myArray = [myString componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"-"]];
这是我获取手机的方法
- (void) getContacts
{
NSMutableDictionary *response = [[NSMutableDictionary alloc] init];
ABAddressBookRef contactBook = ABAddressBookCreateWithOptions(NULL, NULL);
arr_Contacts = [[NSMutableArray alloc] init];
ABAddressBookRef allPeople = contactBook;
CFArrayRef allContacts = ABAddressBookCopyArrayOfAllPeople(allPeople);
CFIndex numberOfContacts = ABAddressBookGetPersonCount(allPeople);
NSLog(@"contact == %@",allContacts);
NSLog(@"numberOfContacts------------------------------------%ld",numberOfContacts);
for(int i = 0; i < numberOfContacts; i++){
NSString* name = @"";
NSString* phone = @"";
NSString* email = @"";
ABRecordRef aPerson = CFArrayGetValueAtIndex(allContacts, i);
ABMultiValueRef fnameProperty = ABRecordCopyValue(aPerson, kABPersonFirstNameProperty);
ABMultiValueRef lnameProperty = ABRecordCopyValue(aPerson, kABPersonLastNameProperty);
ABMultiValueRef phoneProperty = ABRecordCopyValue(aPerson, kABPersonPhoneProperty);
ABMultiValueRef emailProperty = ABRecordCopyValue(aPerson, kABPersonEmailProperty);
NSArray *emailArray = (__bridge NSArray *)ABMultiValueCopyArrayOfAllValues(emailProperty);
NSArray *phoneArray = (__bridge NSArray *)ABMultiValueCopyArrayOfAllValues(phoneProperty);
if (fnameProperty != nil) {
name = [NSString stringWithFormat:@"%@", fnameProperty];
}
if (lnameProperty != nil) {
name = [name stringByAppendingString:[NSString stringWithFormat:@" %@", lnameProperty]];
}
if ([phoneArray count] > 0) {
if ([phoneArray count] > 1) {
for (int i = 0; i < [phoneArray count]; i++) {
phone = [phone stringByAppendingString:[NSString stringWithFormat:@"%@, ", [phoneArray objectAtIndex:i]]];
}
}else {
phone = [NSString stringWithFormat:@"%@", [phoneArray objectAtIndex:0]];
}
}
if ([emailArray count] > 0) {
if ([emailArray count] > 1) {
for (int i = 0; i < [emailArray count]; i++) {
email = [email stringByAppendingString:[NSString stringWithFormat:@"%@n", [emailArray objectAtIndex:i]]];
}
}else {
email = [NSString stringWithFormat:@"%@", [emailArray objectAtIndex:0]];
}
}
NSLog(@"NAME : %@",name);
NSLog(@"PHONE: %@",phone);
NSLog(@"EMAIL: %@",email);
NSLog(@"n");
[response setObject:name forKey:@"name"];
[response setObject:phone forKey:@"phone"];
[response setObject:email forKey:@"email"];
[arr_Contacts addObject:response];
}
}
