我对目标C很新,我正在使用XCode 4.2,在应用程序的一部分中,我需要将数据保存在地址簿中。但我需要将它显示在地址簿中,而不是仅将其保存在按钮上
我正在尝试使用以下代码:
我添加了addressBook
框架和addressBookUI
框架
在我写的.h文件中
#import <UIKit/UIKit.h>
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
@interface HelloWorld20ViewController : UIViewController<ABNewPersonViewControllerDelegate,ABPersonViewControllerDelegate>{
}
-(IBAction)go;
@end
在我写的.m文件中
-(IBAction)go{
ABRecordRef newPerson= ABPersonCreate();
CFErrorRef error = NULL;
ABRecordSetValue(newPerson, kABPersonFirstNameProperty, CFSTR("john"), &error);
ABRecordSetValue(newPerson, kABPersonLastNameProperty, CFSTR("Smith"), &error);
NSAssert(!error, @"something bad happend here.");
ABNewPersonViewController* newPersonViewController = [[ABNewPersonViewController alloc] initWithNibName:nil bundle:nil];
[newPersonViewController setDisplayedPerson:newPerson];
[newPersonViewController setNewPersonViewDelegate:self];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:newPersonViewController];
[self presentModalViewController:navController animated:YES];
CFRelease(newPerson);
}
-(void)newPersonViewController:(ABNewPersonViewController *)newPersonView didCompleteWithNewPerson:(ABRecordRef)person{
[self.navigationController popViewControllerAnimated:YES];
}
当我点击go按钮时,我得到一个黑屏:这是我得到的
这是为什么会这样做的?
非常感谢!
被修改
当前代码:
-(IBAction)go{
ABRecordRef newPerson= ABPersonCreate();
CFErrorRef error = NULL;
ABRecordSetValue(newPerson, kABPersonFirstNameProperty, CFSTR("john"), &error);
ABRecordSetValue(newPerson, kABPersonLastNameProperty, CFSTR("Smith"), &error);
NSAssert(!error, @"something bad happend here.");
ABNewPersonViewController* newPersonViewController = [[ABNewPersonViewController alloc] initWithNibName:nil bundle:nil];
[newPersonViewController setDisplayedPerson:newPerson];
[newPersonViewController setNewPersonViewDelegate:self];
[self presentModalViewController:newPersonViewController animated:YES];
CFRelease(newPerson);
}
仍然是同样的问题
答案 0 :(得分:1)
好的,你的问题就在这里:
ABNewPersonViewController* newPersonViewController = [[ABNewPersonViewController alloc] initWithNibName:nil bundle:nil];
如果用这个替换该行:
ABNewPersonViewController* newPersonViewController = [[ABNewPersonViewController alloc] init];
您的代码运行正常。
