Question

我有一个像userName，DOB，注册号：和地址这样的数据，我创建了10个XIB文件 for detail打开时的视图单击MasterView表单元格时，在详细视图的第二个XIB文件中，当我在第3个XIB中的第二个Xib中选择用户时，我有一个用户信息??我不知道iphone开发中的iphone bcoz m数据委托吗？

Answer 1

在我对你的项目的理解中：

您从MasterViewController（第一个控制器）开始
选择或单击行/单元格后，另一个控制器将加载其中包含的内容用户列表？（我不太确定）其中每个用户都有信息（包含userName，DOB等）。因此，这意味着在此控制器中 - 您将这些信息分配给相应的用户。（第二控制器）
然后，当您选择特定用户时，另一个控制器会加载您要使用此控制器中数据的位置 - 可能是，您希望显示从第二个控制器分配的信息。（第三控制器）

所以，如果我们在同一页面上，这就是你要做的事情：

（比方说，你已经完成了MainView（FirstController）并且你已经在SecondViewController中了）

对于初学者，你可以这样做：

在ThirdViewController中创建一个全局变量，它将保存SecondViewController传递的信息。在这种情况下，

///////// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ///////// ///////// ~~~~~~~~~~~~~~~~~~ ///////// ///////// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /////////

@interface ThirdViewController:UIViewController{
    NSDictionary *dictInformation;
}
@property (nonatomic, retain) NSDictionary *dictInformation;
@end

@implementation ThirdViewController
@synthesize dictInformation;

...
   // some codes here...
   // you can use the information passed from the SecondViewController
...

- (void)dealloc{
     [dictInformation release], dictInformation = nil;
     [super dealloc];
}
@end

///////// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ///////// ///////// ~~~~~~~~~~~~~~~~ ///////// ///////// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /////////

@implementation SecondViewController

    // This is the assignment of data. You can put this in viewDidload
    // user 1
     NSMutableDictionary *aUser1 = [[NSMutableDictionary alloc] init];
    [aUser1 setObject:@"josh123" forKey:@"userName"];
    [aUser1 setObject:@"01-01-1987" forKey:@"dateOfBirth"];
    [aUser1 setObject:@"12345678" forKey:@"regNumber"];
    [aUser1 setObject:@"24-H 1st St. New York" forKey:@"address"];
    // user 2
    NSMutableDictionary *aUser2 = [[NSMutableDictionary alloc] init];
    [aUser2 setObject:@"josh321" forKey:@"userName"];
    [aUser2 setObject:@"01-02-1988" forKey:@"dateOfBirth"];
    [aUser2 setObject:@"87654321" forKey:@"regNumber"];
    [aUser2 setObject:@"42-H 1st St. New York" forKey:@"address"];

   // I assigned all users to an array
    NSArray *arrayOfUsers = [[NSArray alloc] initWithObjects:aUser1, aUser2, nil];
    [aUser1 release];
    [aUser2 release];

   // Pass the value of arrayOfUsers somewhere to that it can be accessed
   // or it can be a 

   /* At this point, the following has values:
   arrayOfUsers[0] = aUser1 -> {'josh123', '01-01-1987', '12345678', '24-H 1st St. New York'}
   arrayOfUsers[1] = aUser2 -> {'josh321', '01-02-1988', '87654321', '42-H 1st St. New York'}
   */

    // You can actually add the following codes anywhere, depending on your implementation. It can be when you clicked a cell or a button, etc.

      ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    // assign a dictionary value to dictInformation which is found in ThirdViewController
    // If you are using UITableView, then, this should be done when you are selecting a cell in the tableView and the value of the index should be indexPath.row
      [thirdViewController setDictInformation:[arrayOfUsers objectAtIndex:0]]; 
      // This pushes to the ThirdViewController
      [self.navigationController pushViewController:thirdViewController animated:YES];
      [thirdViewController release];

      ...
@end

注意：这只是代码片段......我只想告诉您如何操作。但希望这会有所帮助。祝好运！：）
