I'm planning on adding a small subview to the bottom of my current app so that it can display RSS feed headlines one at a time. What would be the best type of view to use for this? UITextView
, UIWebView
? Perhaps a custom UITableViewCell
? If i use a UITextView
and tap it, it displays the keyboard, but if i setUserInteractionEnabled
to NO
then i wont be able to launch a different view with the article...
Scrolling each block of text would be done using core animation right?
Thanks.
Use a UILabel. And yes, you will use Core Animation to animate. Here is a basic UIView animation block that will move a UILabel from the far right of the screen to the left.
// Set your label to display offscreen to the right
[feedLabel setCenter:CGPointMake(
screenWidth + [feedLabel bounds].size.width / 2,
[feedLabel frame].origin.y)];
// Then later animate it into view and then off to the left.
[UIView beginAnimations:nil context:NULL];
// Give it 10 seconds to make it all the way across.
[UIView setAnimationDuration:10.0f];
[feedLabel setCenter:CGPointMake(
0.0 - [feedLabel bounds].size.width / 2,
[feedLabel frame].origin.y)];
[UIView commitAnimations];
Remember that the anchorPoint for a view such as a UILabel is the center of the view. This is why the call to -setCenter is taking half the width of the label to determine where the x coordinate should be. The y coordinate, of course, should just stay the same.
