为 ABPeoplePickerNavigationController 设置委托时收到警告
我正在尝试使用以下代码片段构建一个应用程序
我的界面定义是，
@interface CreateMessageViewController : UIViewController
并且我作为按钮单击结果调用的方法是
-(IBAction) handleEvents:(id) sender
{
if ((UIButton *) sender == openContact)
{
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
}}
现在我收到 picker.peoplePickerDelegate = self; 的警告说
警告：“CreateMessageViewController”类未实现“ABPeoplePickerNavigationControllerDelegate”协议
我无法删除该警告。请在这方面帮助我
任何类型的帮助将不胜感激
提前致谢！
I am trying to build an app with the following code snippets
My Interface definition is
@interface CreateMessageViewController : UIViewController
and the method I am calling as result of Button click is
-(IBAction) handleEvents:(id) sender
{
if ((UIButton *) sender == openContact)
{
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
}}
Now I am getting a warning for picker.peoplePickerDelegate = self; saying
warning: class 'CreateMessageViewController' does not implement the 'ABPeoplePickerNavigationControllerDelegate' protocol
I am not able to remove the warning. Please help me out in this regard
Any kind of help would be highly appreciated
Thanks in advance!!

需要为
peoplePickerDelegate分配支持ABPeoplePickerNavigationControllerDelegate协议的内容，而您的控制器类不支持该协议（self 是控制器的实例，以防您不明显）。尝试并实施相关信号
peoplePickerDelegateneeds to be assigned something that supports theABPeoplePickerNavigationControllerDelegateprotocol which your controller class doesn't (self is an instance of you controller in case that was not obvious to you). Tryand implement the relevant signals
