Question

我有一个困扰我的问题。我必须将iOS中的UI操作表中的信息存储到CoreData中提供的数组中。麻烦的是，操作表与用于存储数据的功能不同。

第一：这是存储数据的相关代码：

(... checking for all fields; working properly)

} 
else
{
    newContact = [NSEntityDescription insertNewObjectForEntityForName:@"Contacts" inManagedObjectContext:context];
    [newContact setValue:Salutation.text forKey:@"Salutation"];
    [newContact setValue:FirstName.text forKey:@"FirstName"];
    [newContact setValue:LastName.text forKey:@"LastName"];
    [newContact setValue:CompanyName.text forKey:@"CompanyName"];
    [newContact setValue:EmailAddress.text forKey:@"EmailAddress"];
    [newContact setValue:PhoneNumber.text forKey:@"PhoneNumber"];
    newContact.Disinfector =[NSNumber numberWithBool:yesWasher];
    newContact.Sterilizer =[NSNumber numberWithBool:yesSterilizer];
    newContact.CoffeeMaker =[NSNumber numberWithBool:yesCoffeeMaker];

    Salutation.text = @"";
    FirstName.text = @"";
    LastName.text = @"";
    CompanyName.text = @"";
    EmailAddress.text = @"";
    PhoneNumber.text = @"";
    yesWasher = YES;
    [WasherTog setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateNormal];
    yesSterilizer = YES;
    [SterilizerTog setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateNormal];
    yesCoffeeMaker = YES;
    [CoffeeMakerTog setImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateNormal];

其次，这是操作表的代码并处理输入：

- (void)showSalutation:(id)sender
{
UIActionSheet *popUp = [[UIActionSheet alloc] initWithTitle:@"Choose Salutation" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Cancel" otherButtonTitles:@"Mr.", @"Mrs.", @"Ms.", @"Dr.", nil];
popUp.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[popUp showInView:self.view];
[popUp release];
}

- (void)showSalutation:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0) 
{
    Salutation.text = @"Mr.";
}
else if (buttonIndex == 1)
{
    Salutation.text = @"Mrs.";
}
else if (buttonIndex == 2)
{
    Salutation.text = @"Ms.";
}
else if (buttonIndex == 3)
{
    Salutation.text = @"Dr.";
}
}

我觉得我犯了很多新手的错误，所以请原谅我。我整个周末都在学习如何编码，你们这些人都是我最好的朋友。我只是没有在网上看到这个特殊问题。

提前感谢您的帮助！

如果您是jsut尝试根据按钮索引选择字符串，请使用实例变量。例如，您可以在标头中声明NSString * yourString并按如下方式使用它：

if (button.index == 0) { yourString = @"Mr." }

只需遵循该模式即可，您可以从那里使用yourString做任何你想做的事。
