我正在尝试获取当前用户的电子邮件(如果有),以便我可以创建自定义的“与我们联系”消息。
代码在C中。我尝试过使用AddressBook.framework,但我找不到获取电子邮件地址的方法。
任何人都知道如何获取电子邮件地址? 谢谢。
答案 0 :(得分:4)
#include <AddressBook/AddressBook.h>
获取所有电子邮件地址:
ABAddressBookRef addressbook = ABGetSharedAddressBook();
ABPersonRef user = ABGetMe(addressbook);
ABMultiValueRef emails = ABRecordCopyValue(user, kABEmailProperty);
if(emails)
{
if(ABMultiValueCount(emails) != 0)
{
for(int i=0;i<ABMultiValueCount(emails);i++)
{
CFStringRef email = ABMultiValueCopyValueAtIndex(emails, i);
// Do something with current email string
CFRelease(email);
}
}
CFRelease(emails);
}
或者,要检查标记为主要电子邮件地址的电子邮件地址:
ABAddressBookRef addressbook = ABGetSharedAddressBook();
ABPersonRef user = ABGetMe(addressbook);
ABMultiValueRef emails = ABRecordCopyValue(user, kABEmailProperty);
if(emails)
{
if(ABMultiValueCount(emails) != 0)
{
CFStringRef primaryIdentifier = ABMultiValueCopyPrimaryIdentifier(emails);
for(int i=0;i<ABMultiValueCount(emails);i++)
{
CFStringRef currentIdentifier = ABMultiValueCopyIdentifierAtIndex(emails, i);
if(currentIdentifier==primaryIdentifier)
{
CFStringRef email = ABMultiValueCopyValueAtIndex(emails, i);
// Do something with primary email string
CFRelease(email);
}
CFRelease(currentIdentifier);
}
CFRelease(primaryIdentifier);
}
CFRelease(emails);
}
并非所有潜在错误都在上述代码中处理,例如如果用户尚未为自己创建地址簿条目,则ABGetMe()
可以返回NULL
。
