Question

我可以通过电话簿阅读联系人并在桌面视图中显示......

当联系人列表中有电话号码和namr时，程序正在成功运行，如果联系人列表中没有姓名或电话号码，则程序崩溃....

任何人都可以帮我解决这个问题，以及如何检查这些条件，在表格视图中显示包含电话号码和姓名的名字.... 我的代码如下

    wantedname=[[NSMutableArray alloc] init];
wantednumber=[[NSMutableArray alloc] init];

ABAddressBookRef addressBook = ABAddressBookCreate();
NSArray *thePeople = (NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

NSString *name;

for (id person in thePeople)
{

    name = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSLog(@"!!!!!! name ---> %@",name);
    ABMultiValueRef multi = ABRecordCopyValue(person, kABPersonPhoneProperty);
    NSString *beforenumber = (NSString *)ABMultiValueCopyValueAtIndex(multi, 0);
    NSLog(@" contacts:%@",beforenumber );
    NSString* removed1=[beforenumber stringByReplacingOccurrencesOfString:@"-"withString:@""];
    NSString* removed2=[removed1 stringByReplacingOccurrencesOfString:@")"withString:@""];
    NSString* removed3=[removed2 stringByReplacingOccurrencesOfString:@" "withString:@""];
    NSString* removed4=[removed3 stringByReplacingOccurrencesOfString:@"("withString:@""];
    NSString* removed5=[removed4 stringByReplacingOccurrencesOfString:@"+"withString:@""];


}

importcontacts *phonecontacts = [[importcontacts alloc] init];
phonecontacts.names = wantedname;
phonecontacts.phonenumbers = wantednumber;

您必须检查某人是否在列表中有联系号码。尝试使用以下修改后的代码

wantedname=[[NSMutableArray alloc] init];

wantednumber = [[NSMutableArray alloc] init];

ABAddressBookRef addressBook = ABAddressBookCreate（）; NSArray * thePeople =（NSArray *）ABAddressBookCopyArrayOfAllPeople（addressBook）;

NSString * name;

for（人们中的id）

{

name = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
NSLog(@"!!!!!! name ---> %@",name);
ABMultiValueRef multi = ABRecordCopyValue(person, kABPersonPhoneProperty);

int count1=ABMultiValueGetCount(multi);
NSLog(@"%d",count1);

if (count1!=0) 
{
      NSString *beforenumber = (NSString *)ABMultiValueCopyValueAtIndex(multi, 0);
      NSLog(@" contacts:%@",beforenumber );
      NSString* removed1=[beforenumber stringByReplacingOccurrencesOfString:@"-"withString:@""];
      NSString* removed2=[removed1 stringByReplacingOccurrencesOfString:@")"withString:@""];
      NSString* removed3=[removed2 stringByReplacingOccurrencesOfString:@" "withString:@""];
      NSString* removed4=[removed3 stringByReplacingOccurrencesOfString:@"("withString:@""];
      NSString* removed5=[removed4 stringByReplacingOccurrencesOfString:@"+"withString:@""];
}

}

importcontacts * phonecontacts = [[importcontacts alloc] init]; phonecontacts.names = wantedname; phonecontacts.phonenumbers = wantednumber;
