iphone - UITableview疑惑

Question

我有一个可以将笔记共享到 evernote 的应用程序，它工作正常我可以在应用程序内将我的笔记上传和下载到 Evernote，我有笔记标题和笔记主题，我将笔记上传到 evernote viz UITableview Controller 。 Textlabel.text 是笔记的标题，detailtextlabel.text 是笔记主题。我只得到 Notesubject 正确的意思是，如果我在 tableview 中有两个带有标题的笔记，就像这样 formate 1) title :firstitle ,notsubject :firstNotessubject 2 )title :secondtitle ,notsubject :secondNotessubject,,然后我按下上传按钮，它将笔记上传到 evernote，但标题仍然是 firstitle 只有笔记，就像这个 formate 1) title :firstitle ,notsubject :firstNotessubject 2)title :firsttitle , notesubject :secondNotessubject.my 上传按钮的代码是

-(IBAction)sendNoteEvernote:(id)sender{
 NSMutableString *strtitle = [[NSMutableString alloc] initWithString:@""]; 
    for (int t = 0; t<[appDelegate.indexArray count]; t++) { 
        NSString * aStringtitle = [[NSString alloc] initWithString:[appDelegate.indexArray objectAtIndex:t]] ;

    note.title =aStringtitle;
    }
        NSMutableString *str = [[NSMutableString alloc] initWithString:@"NOTES:"]; 
        for (int i = 0; i<[appDelegate.notesArray count]; i++) { 
            NSString * aString = [[NSString alloc] initWithString:[appDelegate.notesArray objectAtIndex:i]] ;
            NSString * ENML= [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<!DOCTYPE en-note SYSTEM \"http://xml.evernote.com/pub/enml2.dtd\">\n<en-note>%@",aString];
 ENML = [NSString stringWithFormat:@"%@%@", ENML, @"</en-note>"];
            NSLog(@"%@", ENML);

            // Adding the content & resources to the note
            [note setContent:ENML];
           // [note setTitle:aStringtitle];
            // [note setResources:resources];

            // Saving the note on the Evernote servers
            // Simple error management
            @try {
                [[eversingleton sharedInstance] createNote:note];
                _acteverbackup.hidden = YES;
                _actimageeverbackup.hidden =YES;
            }
            @catch (EDAMUserException * e) {
                _acteverbackup.hidden = YES;
                _actimageeverbackup.hidden =YES;
                NSString * errorMessage = [NSString stringWithFormat:@"Error saving note: error code %i", [e errorCode]];
                proAlertView *alert = [[proAlertView alloc]initWithTitle:@"Evernote" message:errorMessage delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
                [alert setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0] withStrokeColor:[UIColor colorWithHue:0.0 saturation:0.0 brightness:0.0 alpha:1.0]];
                [alert show];
                [alert release];        return;
            }

在上面的代码中，appdelegate.indexarray 是标题，appdelegate.notearray 是主题。我的 UItableview 代码看起来像这样。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}


// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return[appDelegate.notesArray count];
}
/*-(UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypesForRowWithIndexPath:(NSIndexPath *)indexPath
 {

 return UITableViewCellAccessoryCheckmark;

 }*/

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSUInteger row = [indexPath row];
    NSString *CellIdentifier;
    CellIdentifier=[NSString stringWithFormat:@"cell %d",indexPath.row];


    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];    
    if (cell == nil) {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
        cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap;
        cell.detailTextLabel.numberOfLines = 0;
        UIImageView* img = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"bgCELL3@2X-1"]];
        [cell setBackgroundView:img];
        [img release];
        count++;
    }
    NSMutableString *strr=[[NSMutableString alloc]initWithString:[appDelegate.indexArray objectAtIndex:indexPath.section]];
    cell.textLabel.text =strr ;
    cell.textLabel.text = [appDelegate.indexArray objectAtIndex:row];
    cell.textLabel.font = [UIFont fontWithName:@"Georgia" size:14.0]; 
    cell.textLabel.textColor = [UIColor brownColor];


    //NSMutableString *notes=[[NSMutableString alloc]initWithString:[appDelegate.notesArray objectAtIndex:row]];
    //cell.detailTextLabel.text =notes;
    cell.detailTextLabel.font = [UIFont fontWithName:@"Georgia" size:14.0]; 
    cell.detailTextLabel.textColor = [UIColor darkGrayColor];
    cell.detailTextLabel.text = [appDelegate.notesArray objectAtIndex:row];
    //textView.text=notes;

    //[notes release];

    cell.backgroundColor=[UIColor clearColor];
    cell.accessoryType = UITableViewCellAccessoryNone;



    return cell;
}

我的代码有什么错误，请帮我解决这个问题。 提前致谢

尝试更改行:

NSMutableString *strr = [[NSMutableString alloc] initWithString:[appDelegate.indexArray objectAtIndex:indexPath.section]];

到:

NSMutableString *strr = [[NSMutableString alloc] initWithString:[appDelegate.indexArray objectAtIndex: row]];

同时摆脱:

NSUInteger row = [indexPath row];
NSString *CellIdentifier;
CellIdentifier = [NSString stringWithFormat:@"cell %d",indexPath.row];

只需使用:

CellIdentifier = @"noteCellIdentifier";

这与您的问题没有任何关系，但这就是细胞重用的全部内容。

编辑:

这部分代码看起来也很可疑:

for (int t = 0; t<[appDelegate.indexArray count]; t++) { 
    NSString * aStringtitle = [[NSString alloc] initWithString:[appDelegate.indexArray objectAtIndex:t]] ;
    note.title =aStringtitle;
}

不清楚你想做什么，但你可能想把它移到:

for (int i = 0; i<[appDelegate.notesArray count]; i++) { 
    NSString * aStringtitle = [[NSString alloc] initWithString:[appDelegate.indexArray objectAtIndex:i]];  //note: t changed to i
    note.title =aStringtitle;

    NSString * aString = [[NSString alloc] initWithString:[appDelegate.notesArray objectAtIndex:i]];
    NSString * ENML= [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<!DOCTYPE en-note SYSTEM \"http://xml.evernote.com/pub/enml2.dtd\">\n<en-note>%@",aString];
    ENML = [NSString stringWithFormat:@"%@%@", ENML, @"</en-note>"];
    NSLog(@"%@", ENML);
    //....
