如何將NSMutableArray存儲到NSUserDefaults並在TableView中顯示結果？

Question

我想在應用程序中保存來自服務器的通知，並且創建用戶界面以使用戶能夠選擇通知（消息）來讀取。在預定的方法中，我的客戶端控制服務器內的更改，並且通信採用JSON格式。我已經解析過它，並且也可以在NSLog(@"....",..)中看到結果。我也控制從服務器的消息狀態，如果狀態等於1，我將保存消息並添加一個節點到TableView ..現在，誰能幫我關於如何在NSUserDefaults和TableView中傳輸NSMutableArray中的數據？我可以分享代碼或JSON表示過，如果你想.. 這將是更好，如果你可以用一些代碼解釋..謝謝

我決定分享我的一些代碼，

，因爲我已經下writen代碼也一樣，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]; 
     NSUserDefaults *passDef=[NSUserDefaults standardUserDefaults]; 
     [passDef setObject:password forKey:@"passwordKey"]; 
     serverIP=[[NSString alloc] initWithString: serverField.text]; 
     [serverField setText:serverIP]; 
     NSUserDefaults *serverDef=[NSUserDefaults standardUserDefaults]; 
     [serverDef setObject:serverIP forKey:@"serverIPKey"]; 
     [userNameDef synchronize]; 
     [serverDef synchronize]; 
     [passDef synchronize]; 


    UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"BNTPRO " 
                 message:@"Your User Informations are going to be sent to server. Do you accept?" 
                delegate:self 
              cancelButtonTitle:@"OK" 
              otherButtonTitles:@"Cancel", nil]; 
    [message show]; 
} 



    - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex 
    { 
     NSString *title = [alertView buttonTitleAtIndex:buttonIndex]; 

     if([title isEqualToString:@"OK"]) 
     { 
      if([userNameField.text isEqualToString:@""]|| [passwordField.text isEqualToString:@""] || [serverField.text length]<10) 
      { 
       UIAlertView *message1 = [[UIAlertView alloc] initWithTitle:@"BNTPRO " 
                    message:@"Your User Informations are not defined properly!"

                 otherButtonTitles: nil]; 

       [message1 show]; 


     [userNameField resignFirstResponder];

       NSMutableArray *mesID = [NSMutableArray array];//saving meesages to NSMutableArray 
       NSMutableArray *status = [NSMutableArray array];  


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

Answer 1

NSUserDefaults的中顯示NSMutableArray保存：

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

NSUserDefaults的距離得到它：

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

從數組設定值的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; 
} 

希望它可以幫助

沒有此刻Mac附近，所以我的答案可能是b有點馬虎。

在你的頭文件，不要忘記添加的UITableViewDelegate和UITableViewDataSource，所以看起來有點像：

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

然後在實現文件（.M）你可以開始輸入

-tableview 

然後使用自動完成獲取您需要的方法。您將最有可能需要這些3：

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

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

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

根據您的應用程序可能需要更多的人的需求，但這些3應該在那裏。
