UITextView - Horizontal Scrolling? - iphone

Question

How can I create a horizontal scrolling UITextView?
When I set my text programmatically it adds automatic line breaks, so I can only scroll vertically...
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.";
Thanks for your answers.
EDIT:
So far I tried this:
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);
but I received: 'Threat 1: signal SIGABRT'

Answer 1

I have not yet done something like this, but I would try the following steps to accomplish this:
Create a UIScrollview *yourScrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0 ,0 , self.view.frame.size.width, 50)]; //
Use CGFloat textLength = [titleView.text sizeWithFont:titleView.font constrainedToSize:CGSizeMake(9999, 50) lineBreakMode:NSLineBreakByWordWrapping].width;
to get the final length of your text
Set yourScrollView.contentSize = CGSizeMake(textLength + 20, 50); //or some value you like, you may have to try this out a few times
Also set titleTextView.frame = CGRectMake(titleTextView.frame.origin.x, titleTextView.frame.origin.y, textLength, titleTextView.frame.size.height);
Make titleView a subview of yourScrollView: [yourScrollView addSubview: titleView];
Hope this gives you a good start!
EDIT: This Code will work:
Please notice I used a UILabel instead of a 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];
