在iOS上的地址簿中获取图像联系人
我是新的使用通讯簿，我会尝试获取手机中的联系人的一些信息。 是否有可能获得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！
是的，这是完全可能的，你只需要询问每个人的logging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function：
ABPersonHasImageData(person) ABPersonCopyImageDataWithFormat(person) ABPersonCopyImageDataWithFormat返回一个CFDataRef。 使用此（ARC） NSData* data = (__bridge_transfer NSData*) cfData;将其转换为NSData NSData* data = (__bridge_transfer NSData*) cfData;
然后可以使用[UIImage imageWithData:data]创build图像
这是非常好的代码，我发现select所有的联系信息，并可能有助于未来的用户..
在项目中添加AddressBookUI和AddressBook框架
.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
