需求

• 由于之前使用第三方跳轉(zhuǎn)通訊錄，點(diǎn)擊聯(lián)系人默認(rèn)獲取第一個手機(jī)號，現(xiàn)在需要根據(jù)聯(lián)系人的手機(jī)號數(shù)量，只有1個，點(diǎn)擊該聯(lián)系人后直接dimiss，如果數(shù)量大于1，需要跳轉(zhuǎn)至聯(lián)系人詳情進(jìn)行選擇后dismiss。

前提

• 由于本文是解決該需求問題記錄，前提默認(rèn)您已了解iOS通訊錄的相關(guān)框架，如未了解，請先翻閱以下幾篇文章，謝謝。
  iOS 通訊錄相關(guān)
  iOS通訊錄開發(fā)

未解決前方案

• 如果您已了解AddressBook框架，話不多說上代碼：
  #import <AddressBook/ABPerson.h>
#import <AddressBookUI/AddressBookUI.h>
• 點(diǎn)擊跳轉(zhuǎn)通訊錄的事件

- (void)btnClick{
  //聯(lián)系人選擇控制器
 ABPeoplePickerNavigationController *nav = [[ABPeoplePickerNavigationController alloc]init];
//設(shè)置代理 ABPeoplePickerNavigationControllerDelegate
    nav.peoplePickerDelegate =self;
//彈出視圖
    [self presentViewController:nav animated:YES completion:nil];
}

• 代理
  系統(tǒng)方案實(shí)現(xiàn)有兩個代理：
  1.實(shí)現(xiàn)peoplePickerNavigationController:didSelectPerson:
  2.實(shí)現(xiàn)peoplePickerNavigationController:didSelectPerson: property:identifier:(ABMultiValueIdentifier)identifier
  該方法在8以后，是直接跳轉(zhuǎn)詳情頁，不實(shí)現(xiàn)，就會直接走第一種方案。

//ios 7 方法
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person{
    ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
    
    NSString *personName = (__bridge_transfer NSString *) ABRecordCopyCompositeName(person);
    NSLog(@"%@", personName);
    
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
    NSString *phoneNo = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, 0);
//遍歷拿到所有的phonenumber，當(dāng)前取第0個
//    for (NSUInteger phoneCounter = 0; phoneCounter < ABMultiValueGetCount(phones); phoneCounter++)
//    {
//        
//        phoneNo = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, phoneCounter);
//        
//        NSLog(@"phone : %@",phoneNo);
//        
//    }
    
    if ([phoneNo hasPrefix:@"+"]) {
        
        phoneNo = [phoneNo substringFromIndex:3];
    }
    
    phoneNo = [phoneNo stringByReplacingOccurrencesOfString:@"-" withString:@""];
    NSLog(@"%@", phoneNo);
    
    if (phone && personName) {
        [peoplePicker dismissViewControllerAnimated:YES completion:nil];
        return;
    }
}
//ios 8 以上
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
    ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty);
    long index = ABMultiValueGetIndexForIdentifier(phone, identifier);
    
    NSString *phoneNo = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index);
    
    NSString *personName = (__bridge_transfer NSString *) ABRecordCopyCompositeName(person);
    NSLog(@"%@", personName);
    
    if ([phoneNo hasPrefix:@"+"]) {
        
        phoneNo = [phoneNo substringFromIndex:3];
    }
    
    phoneNo = [phoneNo stringByReplacingOccurrencesOfString:@"-" withString:@""];
    NSLog(@"%@", phoneNo);
    
    if (phone && personName) {
        [peoplePicker dismissViewControllerAnimated:YES completion:nil];
        return;
    }
    
}

上述方法，直接走第一種代理。
重點(diǎn)來了！

- (void)btnClick{
  //聯(lián)系人選擇控制器
 ABPeoplePickerNavigationController *nav = [[ABPeoplePickerNavigationController alloc]init];
//設(shè)置代理 ABPeoplePickerNavigationControllerDelegate
nav.peoplePickerDelegate =self;
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0f) {
        nav.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
}
//彈出視圖
    [self presentViewController:nav animated:YES completion:nil];
}

if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0f) {
        nav.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false];
}

加上這一段話后，可實(shí)現(xiàn)，在iOS8以上，點(diǎn)擊聯(lián)系人跳轉(zhuǎn)到詳情頁。
但是還是沒有按照需求實(shí)現(xiàn)！

解決方案

if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0f) {
        nav.predicateForSelectionOfPerson = [NSPredicate predicateWithFormat:@"phoneNumbers.@count == 1"];
}

正確的NSPredicate（謂詞）篩選，達(dá)到了所需效果。此方法適用iOS8以上。
