将plist读入TableView [英] Reading plist into TableView

问题描述

我用一个带有两个字符串数组的字典的简单plist开始了这个项目。我现在想要添加更多信息并想要使用这个plist结构：

I started this project with a simple plist of a dictionary with two arrays of strings. I now want to add more information and want to use this plist structure:

Root - Dictionary - (2 items)
   Standard - Array - (3 items)
      Item 0 - Dictionary - (4 items)
           Color - String - Red
           Rvalue - String - 255
           Gvalue - String - 0
           Bvalue - String - 0

很抱歉输入了plist但该网站不会让我发布图片

Sorry about typing in the plist but the site would not let me post an image

我知道RGB值可能是数字而不是字符串，但我有理由将它们作为字符串。

I know that the RGB values could be numbers instead of strings but I have a reason for them being strings.

这是我用来读简单plist的代码：

This is the code I used to read the simple plist:

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

    NSUInteger section = [indexPath section];
    NSUInteger row = [indexPath row];
    NSString *key = [keys objectAtIndex:section];
    NSArray *colorSection = [colors objectForKey:key];

    static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];

    if(cell == nil){
        cell=[[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SectionsTableIdentifier] autorelease];
        }

    cell.textLabel.text = [colorSection objectAtIndex:row];
    [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton]; //add disclosure button to rows
    return cell;
}

我的问题是检索颜色词典内容的具体代码是什么获取cell.textLabel.text的颜色，并读取RGB值以添加字幕。我已经在这方面工作了好几天，并且阅读了参考文献和很多例子，遗憾的是无法解决问题。非常感谢您的帮助。

My question is what is the specific code to retrieve the contents of the color dictionaries to get the Colors for the cell.textLabel.text and also read the RGB values to add a subtitle. I've been working on this for several days and have read references and lots of examples and unfortunately can't solve the problem. Your assistance will be greatly appreciated.

推荐答案

首先，不要使用 - [UITableViewCell initWithFrame：reuseIdentifier：]。它已被弃用，并会给你一个警告，此外它会使你的字幕更难实现。此代码是您的修改版本，它加载信息，将标题设置为Color属性，并将字幕设置为包含Rvalue，Gvalue和Bvalue属性的字符串。

First, do not use -[UITableViewCell initWithFrame:reuseIdentifier:]. It has been deprecated and will give you a warning, plus it will make your subtitle harder to implement. This code is a modified version of yours which loads the information, sets the title to the Color property, and sets the subtitle to a string containing the Rvalue, Gvalue, and Bvalue properties.

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

    NSUInteger section = [indexPath section];
    NSUInteger row = [indexPath row];
    NSString *key = [keys objectAtIndex:section];
    NSArray *colorSection = [colors objectForKey:key];

    static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];

    if(cell == nil) {
        cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier: SectionsTableIdentifier] autorelease];
    }

    NSDictionary *color = [colorSection objectAtIndex:row];
    cell.textLabel.text = [color objectForKey:@"Color"];
    cell.detailTextLabel.text = [NSString stringWithFormat:@"%@, %@, %@",[color objectForKey:@"Rvalue"],[color objectForKey:@"Gvalue"],[color objectForKey:@"Bvalue"]];
    [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton]; //add disclosure button to rows
    return cell;
}
