如何将NSMutableArray存储到NSUserDefaults并在TableView中显示结果？

Question

我想在应用程序中保存来自服务器的通知，并且创建用户界面以使用户能够选择通知（消息）来读取。在预定的方法中，我的客户端控制服务器内的更改，并且通信采用JSON格式。我已经解析过它，并且也可以在NSLog(@"....",..)中看到结果。我也控制从服务器的消息状态，如果状态等于1，我将保存消息并添加一个节点到TableView ..现在，谁能帮我关于如何在NSUserDefaults和TableView中传输NSMutableArray中的数据？我可以分享代码或JSON表示过，如果你想.. 这将是更好，如果你可以用一些代码解释..谢谢

我决定分享我的一些代码，

，因为我已经下writen代码也一样，我想在UITableView

`-(IBAction)Accept:(id)sender 
    { userName=[[NSString alloc] initWithString:userNameField.text ]; 
     [userNameField setText:userName]; 
     NSUserDefaults *userNameDef= [NSUserDefaults standardUserDefaults]; 
     [userNameDef setObject:userName forKey:@"userNameKey"]; 
     password =[[NSString alloc] initWithString:passwordField.text]; 
     [passwordField setText:password];

     [passDef setObject:password forKey:@"passwordKey"]; 
     serverIP=[[NSString alloc] initWithString: serverField.text];

       // i logged here and it saves the data, now i want to display my data in table view

Answer 1

NSUserDefaults的中显示NSMutableArray保存：

[[NSUserDefaults standardUserDefaults]setObject:yourArray forKey:@"theArray"]; 

NSUserDefaults的距离得到它：

[[NSUserDefaults standardUserDefaults]objectForKey:@"theArray"]; 

从数组设定值的UITableViewCell：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    static NSString *CellIdentifier = @"TheCell"; 
    UITableViewCell *_cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (_cell == nil) { 
     _cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
    } 
    _cell.textLabel.text = [yourArray objectAtIndex:indexPath.row]; 
    return _cell; 
} 

希望它可以帮助

没有此刻Mac附近，所以我的答案可能是b有点马虎。

在你的头文件，不要忘记添加的UITableViewDelegate和UITableViewDataSource，所以看起来有点像：

@interface yourController : UIViewController <UITableViewDelegate, UITableViewDataSource, ... some others if you need it ...> { 

然后在实现文件（.M）你可以开始输入

-tableview 

然后使用自动完成获取您需要的方法。您将最有可能需要这些3：

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath 

根据您的应用程序可能需要更多的人的需求，但这些3应该在那里。
