Question

I’m new to IOS development, and I’m just trying to get my head around all the views. At first I have a UITextField which is one line and I wanted it to wrap. I was told to implement a UITextView instead – and that worked! I then had many lines of wrapped text.

The next thing I wanted to do was have horizontally scrolling pages. I downloaded apple’s page control example. In it many pages are created with a little text label. I altered this to contain a very long string, and replaced the UILabel type with a UITextView. However, it’s not word wrapping! The cause could be anything an I have absolutely no idea what it might be. Perhaps it’s inheriting some setting from something?

Any help would be much appreciated.

Edit – here is where the views are created:

- (void)loadScrollViewWithPage:(int)page
{
if (page < 0)
    return;
if (page >= kNumberOfPages)
    return;

MyViewController *controller = [viewControllers objectAtIndex:page];
if ((NSNull *)controller == [NSNull null])
{
    controller = [[MyViewController alloc] initWithPageNumber:page];
    [viewControllers replaceObjectAtIndex:page withObject:controller];
    [controller release];
}

if (controller.view.superview == nil)
{
    CGRect frame = scrollView.frame;
    frame.origin.x = frame.size.width * page;
    frame.origin.y = 0;
    controller.view.frame = frame;
    [scrollView addSubview:controller.view];

    NSDictionary *numberItem = [self.contentList objectAtIndex:page];

    controller.numberTitle.text = [numberItem valueForKey:NameKey];
}
}

and this is the MyViewController header:

#import <UIKit/UIKit.h>

@interface MyViewController : UIViewController
{
UILabel *pageNumberLabel;
int pageNumber;

UITextView *numberTitle;
UIImageView *numberImage;
}

@property (nonatomic, retain) IBOutlet UILabel *pageNumberLabel;

@property (nonatomic, retain) IBOutlet UITextView *numberTitle;
@property (nonatomic, retain) IBOutlet UIImageView *numberImage;

- (id)initWithPageNumber:(int)page;

@end

Check the frame of the UITextView. It’s possible if you just swapped UITextView with UILabel that the frame is not large enough. Change the frame to have a larger height. Also, set the background color to a bright color so you know can see how large it is on the screen.
