1.引入头文件
#import <AddressBook/AddressBook.h>
2.启动项目时判断是否授权获取通讯录
2.1获取授权状态
ABAuthorizationStatusstatus =ABAddressBookGetAuthorizationStatus();
2.2判断授权状态，如果是未决定状态，才需要请求获取授权
if(status ==kABAuthorizationStatusNotDetermined)
2.3如果是未决定状态，则创建通信录对象
ABAddressBookRef addressBook =ABAddressBookCreateWithOptions(NULL,NULL);
2.4请求授权
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted,CFErrorRef error) {
if(granted) {
NSLog(@"授权成功");
}else{
NSLog(@"授权失败");
}
});
3.触发获取用户通信录的行为时，同样要先验证是否授权获取用户通信录，如果验证成功，则继续，否则提示用户权限验证失败，引导用户去设置页面打开权限
3.1创建通讯录对象
ABAddressBookRef addressBook =ABAddressBookCreateWithOptions(NULL,NULL);
3.2从通信录对象中，将所有的联系人拷贝出来
CFArrayRef peopleArray =ABAddressBookCopyArrayOfAllPeople(addressBook);
3.3遍历所有的联系人
CFIndexpeopleCount =CFArrayGetCount(peopleArray);
for(CFIndexi =0; i < peopleCount; i++) {
//获取到联系人
ABRecordRefperson =CFArrayGetValueAtIndex(peopleArray, i);
// 获取姓名
NSString*lastname = (__bridge_transferNSString*)ABRecordCopyValue(person,kABPersonLastNameProperty);
NSString*firstName = (__bridge_transferNSString*)ABRecordCopyValue(person,kABPersonFirstNameProperty);
NSLog(@"%@ %@", lastname, firstName);
}
3.4释放不在使用的对象，都则造成内存泄露
CFRelease(peopleArray);
CFRelease(addressBook);
