无法设置ABPeoplePickerNavigationController的addressBook属性，而不会崩溃 [英] Can't set the addressBook property of ABPeoplePickerNavigationController without crashing

问题描述

因此，我创建一个地址簿，并删除没有地址的用户：

p>

  addressBook = ABAddressBookCreate（）; 
 NSArray * peopleList =（NSArray *）ABAddressBookCopyArrayOfAllPeople（addressBook）; 
 NSLog（@addressBook中有％d个人，ABAddressBookGetPersonCount（addressBook））; 
 for（id peopleRecord in peopleList）{
 ABMultiValueRef mv = ABRecordCopyValue（（ABRecordRef）peopleRecord，kABPersonAddressProperty）; 
 CFIndex numberOfAddresses = ABMultiValueGetCount（mv）; 
 if（numberOfAddresses == 0）{
 CFErrorRef err; 
 ABAddressBookRemoveRecord（addressBook，（ABRecordRef）peopleRecord，& err）; 
} 
} 
 [peopleList release]; 
 NSLog（@现在有％d个人在addressBook，ABAddressBookGetPersonCount（addressBook））; 
 ABPeoplePickerNavigationController * peoplePicker = [[ABPeoplePickerNavigationController alloc] init]; 
 NSNumber * addressProp = [NSNumber numberWithInt：kABPersonAddressProperty]; 
 [peoplePicker setAddressBook：addressBook]; 
 peoplePicker.displayedProperties = [NSArray arrayWithObject：addressProp]; 
 [peoplePicker setPeoplePickerDelegate：self]; 
 [self presentModalViewController：peoplePicker animated：YES]; 
 

有关信息，在过滤前我有125条记录，过滤后我有93条记录。

当我显示peoplePicker并滚动通过它，它崩溃与：

  ***由于未捕获异常NSRangeException终止应用程序，原因：'***  -  [NSCFArray objectAtIndex：]：index（49）超出边界（49）'
  

任何想法出了什么问题？

解决方案

NSRangeException值是49（而不是一些数字在93和125之间），我最初怀疑它不直接与这个地址簿相关。为 objc_exception_throw 添加一个断点。这将导致你在异常的时候进入调试器，让你看看谁实际上抛出它。

I want to display an ABPeoplePicker with only people who have a geographic address defined.

So I create an addressBook and remove people that dont have an address:

addressBook = ABAddressBookCreate();
NSArray *peopleList = (NSArray *)ABAddressBookCopyArrayOfAllPeople( addressBook );
NSLog(@"There are %d people in addressBook", ABAddressBookGetPersonCount(addressBook));
for (id peopleRecord in peopleList) {
  ABMultiValueRef mv = ABRecordCopyValue((ABRecordRef)peopleRecord, kABPersonAddressProperty);
  CFIndex numberOfAddresses = ABMultiValueGetCount(mv);
  if( numberOfAddresses == 0 ) {
    CFErrorRef err;
    ABAddressBookRemoveRecord( addressBook, (ABRecordRef)peopleRecord, &err);
  }
}
[peopleList release];
NSLog(@"There are now %d people in addressBook", ABAddressBookGetPersonCount(addressBook));
ABPeoplePickerNavigationController *peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
NSNumber* addressProp = [NSNumber numberWithInt:kABPersonAddressProperty];
[peoplePicker setAddressBook:addressBook];
peoplePicker.displayedProperties = [NSArray arrayWithObject:addressProp];
[peoplePicker setPeoplePickerDelegate:self];
[self presentModalViewController:peoplePicker animated:YES];

For info, before filtering I have 125 records, and after filtering I have 93 records.

When I display the peoplePicker and scroll through it, it crashes with:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (49) beyond bounds (49)'

Any idea what's wrong?

解决方案

The fact that the NSRangeException's value is 49 (rather than some number between 93 and 125), I initially suspect that it's not directly related to this address book. Add a breakpoint for objc_exception_throw. That will cause you to drop into the debugger at the point of the exception, letting you see who's actually throwing it.
