在 UITableView 中显示 TTStyledTextLabel [英] Display A TTStyledTextLabel in a UITableView

问题描述

如何在 UITableView 中设置 TTStyledTextLabel.每个 TTStyledTextLabel 包含一些解析的 HTML.

How can I set a TTStyledTextLabel inside of a UITableView. Each TTStyledTextLabel contains Some parsed HTML.

这是我所拥有的，我意识到它可能完全错误.

Heres what I have I realize its probably completely wrong.

TTStyledTextLabel* label = [[TTStyledTextLabel alloc] autorelease];
cell.textLabel.text = [TTStyledText textFromXHTML:tempString lineBreaks:YES URLs:YES];

应用在启动时崩溃.我认为这是因为我正在使用非文本的内容设置 .text 属性.但是，我不知道还要设置什么.

App Crashes on launch. I think its because I am setting the .text property with something that is not text. However, I don't know what else to set.

推荐答案

以下代码将满足您的需求.不幸的是，我无法弄清楚如何自动设置高度.如果内存不是问题，您可以保留一个单独的 TTStyledTextLabels 数组并参考它们的高度.

The following code will do what you want. Unfortunately, however, I cannot figure out how to automatically set the height. If memory isn't an issue you could keep a seperate array of TTStyledTextLabels and reference their heights.

在您的加载视图中:

CGRect cgRct2 = CGRectMake(0, 35, 320, 375); //define size and position of view 
    tblView = [[UITableView alloc] initWithFrame:cgRct2 style:UITableViewStylePlain];
    tblView.dataSource = [self constructDataSource];
    tblView.delegate = self;
    //[tblView reloadData];
    [myView addSubview:tblView];

在你的班级:

-(TTListDataSource *)constructDataSource {
    NSLog(@"constructDataSource");
    NSMutableArray * namesArray = [[NSMutableArray alloc] init];

    //ADD ITEMS
    [namesArray addObject:[TTStyledText textFromXHTML:[NSString stringWithString:@"some XHTML"]]];




    TTListDataSource * dataSource = [[TTListDataSource alloc] init];
    for (int i = 0; i < [namesArray count]; i++) {
        TTStyledText * text = [namesArray objectAtIndex:i];

        [dataSource.items addObject:[TTTableStyledTextItem itemWithText:text]];
    }

    [namesArray release];
    return dataSource;
}
