property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{

//点击联系人详情里面的属性，对相应的属性做处理
ABMultiValueRef values=ABRecordCopyValue(person, property);

CFIndex ix=ABMultiValueGetIndexForIdentifier(values, identifier);

CFStringRef value=ABMultiValueCopyValueAtIndex(values, ix);
NSLog(@"%@",value);
CFRelease(values);
CFRelease(values);

//获取某个值的标识器

CFIndex identifie=ABMultiValueGetIdentifierAtIndex(values, ix);
NSLog(@"identifier=%ld",identifie);

//限制用户可以看到的属性

peoplePicker.displayedProperties=[NSArrayarrayWithObject:[NSNumbernumberWithInt:kABPersonEmailProperty]];

returnNO;//默认操作为选择进入相应的应用程序，比如打电话就进入电话程序
