ios - 在 iOS 上的通讯录中获取图片联系人

Question

我是使用地址簿的新手，我会尝试获取手机中联系人的一些信息。是否可以获取所有联系人的图像联系人？这将适用于 iOS4 或更高版本。

提前致谢！

Answer 1

是的，这完全有可能，您只需询问每个人的记录是否有图像：

请参阅文档：http: //developer.apple.com/library/ios/#documentation/AddressBook/Reference/ABPersonRef_iPhoneOS/Reference/reference.html#//apple_ref/doc/uid/TP40007210

相关功能：

ABPersonHasImageData(person)
ABPersonCopyImageDataWithFormat(person)

ABPersonCopyImageDataWithFormat返回一个 CFDataRef 。使用此 (ARC) 将其转换为 NSDataNSData* data = (__bridge_transfer NSData*) cfData;

然后可以使用创建图像[UIImage imageWithData:data]

Answer 2

这是我发现选择所有联系人信息的非常好的代码，可能对未来的用户有帮助..

在项目中添加 AddressBookUI 和 AddressBook 框架

比在 .h 文件中

#import <UIKit/UIKit.h>
#import <AddressBookUI/AddressBookUI.h>

@interface ViewController : UIViewController<ABPeoplePickerNavigationControllerDelegate,UIAlertViewDelegate,UITextFieldDelegate,UINavigationControllerDelegate>
{
    NSString * toEmail;
}

- (IBAction)getCaontactDetail:(id)sender;

@end

在 .m 文件中

 - (IBAction)getCaontactDetail:(id)sender {
    //open contact book
    ABPeoplePickerNavigationController *addressBookController = [[ABPeoplePickerNavigationController alloc]init];
    addressBookController.peoplePickerDelegate = self;
    addressBookController.delegate = self;

    addressBookController.navigationBar.tintColor = [UIColor redColor];
    addressBookController.searchDisplayController.searchBar.tintColor = [UIColor redColor];
    addressBookController.searchDisplayController.searchBar.backgroundColor = [UIColor blackColor];

    if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
        [self presentViewController:addressBookController animated:YES completion:nil];
    } else {
        [self presentModalViewController:addressBookController animated:YES];
    }

    addressBookController = nil;
