How to make UITextView scroll up when entering it?

Question

Hi,

I have a UITextView included in a UITableViewCell. The layout is correct when the views are initially displayed, but once I click in the UITextView it DOES NOT automatically scrolls up and the whole UITextView becomes invisible.

This image is when the UITextView is not active:

And this one is when I clicked in the UITextView to make it active:

I want the cell with the UITextView to scroll up. How can I achieve this?

Any suggestions are appreciated.

Answer 1

The simplest way would be to make an IBOutlet for the items you want to move up, and then in the code do something like this when your text field is selected:

myTextView.center.y = 200 or whatever y value you see fit.

Answer 2

I've already done it. My solution is not the best but it works very well: everything happens on tableView:cellForRowAtIndexPath:

1) For every cell that has a UITextView I have a NSDictionary: I save all my UITextView's on the cells on NSDictionary with a particular key.

2) And I also have another NSDictionary with the indexPath objects that are created in tableView:cellForRowAtIndexPath. If a cell A has UITextView A, they will have the same key in the NSDictionaries.

3) I implement the UITextViewDelegate and call textViewDidBeginEditing: here is my code:

• (void)textFieldDidBeginEditing: (UITextField *)textField {

NSArray *keys = [self.answersDic allKeysForObject:textField];

id *key = (id *)[keys objectAtIndex:0];

NSIndexPath *tempIndex=[self.indexPathForViews objectForKey:key];

[tableViewLocal scrollToRowAtIndexPath:tempIndex atScrollPosition:UITableViewScrollPositionTop animated:YES];

}

OBSERVATIONS:

a) answersDic is the NSDictionary where my UITextViews are saved.

b) indexPathForViews is the NSDictionary where my IndexPaths are saved.

c) the most important part of this code: the method, that brings the view to scroll up:

[tableViewLocal scrollToRowAtIndexPath:tempIndex atScrollPosition:UITableViewScrollPositionTop animated:YES];

So, thats it. Thanks for your help!
