UITextView - 水平滚动？

Question

我该如何创建一个水平滚动的UITextView？

当我通过编程设置文本时，它会自动添加换行符，因此我只能垂直滚动...

 titleView.text = @"this is a very long text. this is a very long text. this is a very long text. this is a very long text. this is a very long text.";

感谢你的回答。

编辑： 到目前为止，我尝试了以下内容：

 UIScrollview *yourScrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0 ,0 ,       self.view.frame.size.width, 50)];
CGFloat textLength = [titleView.text sizeWithFont:titleView.font constrainedToSize:CGSizeMake(9999, 50) lineBreakMode:NSLineBreakByWordWrapping].width;

yourScrollview.contentSize = CGSizeMake(textLength + 200, 500); //or some value you like, you may have to try this out a few times

titleView.frame = CGRectMake(titleView.frame.origin.x, titleView.frame.origin.y, textLength, titleView.frame.size.height);

[yourScrollview addSubview: titleView];

NSLog(@"%f", textLength);

但我收到了这样的信息：'威胁 1：信号 SIGABRT'

我还没有做过这样的事情，但我会尝试以下步骤来完成：

1. 创建一个 UIScrollview *yourScrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0 ,0 , self.view.frame.size.width, 50)]; //

2. 使用 CGFloat textLength = [titleView.text sizeWithFont:titleView.font constrainedToSize:CGSizeMake(9999, 50) lineBreakMode:NSLineBreakByWordWrapping].width; 来获取您的文本的最终长度

3. 设置 yourScrollView.contentSize = CGSizeMake(textLength + 20, 50); //或者一些您喜欢的值，您可能需要尝试几次

4. 还要设置 titleTextView.frame = CGRectMake(titleTextView.frame.origin.x, titleTextView.frame.origin.y, textLength, titleTextView.frame.size.height);

5. 将titleView作为yourScrollView的子视图：[yourScrollView addSubview: titleView];

希望这能给您一个良好的开端！

编辑：这段代码将有效：

请注意，我使用了UILabel而不是UITextView。

    UILabel *titleView          = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 40)];
    titleView.text              = @"this is a very long text. this is a very long text. this is a very long text. this is a very long text. this is a very long text.";
    titleView.font              = [UIFont systemFontOfSize:18];
    titleView.backgroundColor   = [UIColor clearColor];
    titleView.numberOfLines     = 1;

    UIScrollView *myScrollView  = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)];
    CGFloat textLength          = [titleView.text sizeWithFont:titleView.font constrainedToSize:CGSizeMake(9999, 50) lineBreakMode:NSLineBreakByWordWrapping].width;
    myScrollView.contentSize    = CGSizeMake(textLength + 20, 50); //or some value you like, you may have to try this out a few times

    titleView.frame             = CGRectMake(titleView.frame.origin.x, titleView.frame.origin.y, textLength, titleView.frame.size.height);

    [myScrollView addSubview: titleView];
    [self.view addSubview:myScrollView];
    [titleView release];
    [myScrollView release];

在将“yourScrollView”添加为子视图后，我收到了“Threat 1: signal SIGABRT”的错误信号。 - Lorenz Wöhr

请更新您的问题并提供一些代码，以便人们可以看到您已经尝试了什么。 - pmk

你的代码肯定出了问题。我已经解决了，可以看看我上面的回答。 - pmk

尝试了很多UITextView的方法，最终只能采用这种方式。 - Prat
