我正在尝试在新的 CNContactViewController 上显示 CNContact。我没有选择任何卡。我用未保存的联系人试过这个(不行)。还尝试使用 saved+fetched from CNContactStore 也没有成功。尝试与“我”联系,但结果相同。根据调试器,获取的联系人加载了正确的值并且不是零/空。应用程序被沙盒化并正确请求联系人权限。
这是示例:
#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>
#import "AppDelegate.h"
@interface AppDelegate ()
@property (weak) IBOutlet NSWindow *window;
@property (strong) CNContact *contact;
@property (strong) CNContactViewController *controller;
@end
@implementation AppDelegate
- (instancetype)init {
self = [super init];
if (self) {
_controller = [[CNContactViewController alloc] init];
}
return self;
}
- (void)awakeFromNib
{
CNContactStore *store = [[CNContactStore alloc] init];
CNMutableContact *mutContact = [[CNMutableContact alloc] init];
NSString *identifier = [mutContact identifier];
mutContact.givenName = @"GivenName";
mutContact.familyName = @"FamilyName";
CNSaveRequest *saveRequest = [[CNSaveRequest alloc] init];
[saveRequest addContact:mutContact toContainerWithIdentifier:[store defaultContainerIdentifier]];
[store executeSaveRequest:saveRequest error:nil];
id keysToFetch = @[[CNContactViewController descriptorForRequiredKeys]];
_contact = [store unifiedContactWithIdentifier:identifier keysToFetch:keysToFetch error:nil];
dispatch_async(dispatch_get_main_queue(), ^{
self.controller.contact = self.contact;
self.window.contentViewController = self.controller;
self.window.contentView = self.controller.view;
});
}
@end

Apple 的 TSI 确认他们无法让它在 OS X 10.11.0 上运行
最佳答案
解决方案是加载 View 后设置联系人。
TSI: Thank you for your patience while I was reaching out to the Contacts engineers. Your issue is a bug whose workaround is to set the contact after presenting the contact view controller.
#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>
#import "ViewController.h"
@interface ViewController()
@property (strong) CNContactStore *store;
@property (strong) CNContactViewController *controller;
@property(nonatomic, copy) NSString *contactIdentifier;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.store = [[CNContactStore alloc] init];
[self saveContact];
}
-(void)saveContact
{
CNMutableContact *mutContact = [[CNMutableContact alloc] init];
mutContact.givenName = @"GivenName";
mutContact.familyName = @"FamilyName";
CNSaveRequest *saveRequest = [[CNSaveRequest alloc] init];
[saveRequest addContact:mutContact toContainerWithIdentifier:[self.store defaultContainerIdentifier]];
[self.store executeSaveRequest:saveRequest error:nil];
self.contactIdentifier = [mutContact identifier];
}
- (void)setRepresentedObject:(id)representedObject {
[super setRepresentedObject:representedObject];
// Update the view, if already loaded.
}
- (IBAction)displayContact:(id)sender {
id keysToFetch = @[[CNContactViewController descriptorForRequiredKeys]];
CNContact *contact = [self.store unifiedContactWithIdentifier:self.contactIdentifier keysToFetch:keysToFetch error:nil];
self.controller = [[CNContactViewController alloc] init];
[self.controller.view setFrameSize:NSMakeSize(500, 500)];
[self presentViewController:self.controller asPopoverRelativeToRect:self.view.bounds ofView: self.view preferredEdge: NSMaxXEdge behavior:NSPopoverBehaviorTransient];
self.controller.contact = contact;
}
