如何將從地址簿檢索到的信息保存到NSUserDefaults？

Question

我想使用PeoplePicker來檢索聯繫人的名稱和地址，並將其存儲到NSUserDefaults中，我最終希望在桌面視圖中檢索它。

我的問題是如何將信息保存在NSUserDefaults中。 我已經使用NSDictionary，但我沒有取得任何進展。 所以我試圖將數組保存到NSUserDefaults。

有人可以幫助我嗎？

我的代碼如下所示：

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker 
     shouldContinueAfterSelectingPerson:(ABRecordRef)person 
           property:(ABPropertyID)property 
           identifier:(ABMultiValueIdentifier)identifier { 

    // Only inspect the value if it's an address. 
    if (property == kABPersonAddressProperty) { 
     ABMutableMultiValueRef multiValue = ABRecordCopyValue(person, property); 
     for(CFIndex i=0;i<ABMultiValueGetCount(multiValue);i++) 
     { 
      ABMultiValueRef multi = ABRecordCopyValue(person, property); 

     // Set up an NSArray and copy the values in. 
     NSArray *theArray = [(id)ABMultiValueCopyArrayOfAllValues(multi) autorelease]; 

     // Figure out which values we want and store the index. 
     const NSUInteger theIndex = ABMultiValueGetIndexForIdentifier(multi, identifier); 

     // Set up an NSDictionary to hold the contents of the array. 
     NSDictionary *dictionary = [theArray objectAtIndex:theIndex]; 

     // Set up NSStrings to hold keys and values. First, how many are there? 
     const NSUInteger theCount = [dictionary count]; 
     NSString *keys[theCount]; 
     NSString *values[theCount]; 

     // Get the keys and values from the CFDictionary. Note that because 
     // we're using the "GetKeysAndValues" function, you don't need to 
     // release keys or values. It's the "Get Rule" and only applies to 
     // CoreFoundation objects. 
     [dictionary getObjects:values andKeys:keys]; 

     // Set the address label's text. 
     NSString *address; 
     address = [NSString stringWithFormat:@"%@, %@, %@", 
        [dictionary objectForKey:(NSString *)kABPersonAddressStreetKey], 
        [dictionary objectForKey:(NSString *)kABPersonAddressCityKey], 
        [dictionary objectForKey:(NSString *)kABPersonAddressCountryKey]]; 

     NSLog(@"%@", address); 

     [self dismissModalViewControllerAnimated:YES]; 
     [self.navigationController popViewControllerAnimated:YES]; 
    } 
    NSUserDefaults *locatie = [NSUserDefaults standardUserDefaults]; 
    CFRelease(multiValue); 
} 

    return NO; 
} 

Answer 1

[locatie setObject:yourObject forKey:@"YoureKey"]; 

如果你想存儲ADRESS使用：

[locatie setObject:adress forKey:@"adressKey"]; 

以檢索使用：

adress = [locatie valueForKey:@"adressKey"]; 

注： 在這些例子中catie是：NSUserDefaults *locatie = [NSUserDefaults standardUserDefaults];
