IOS 7 - Can't set font color of UITextView in custom UITableView cell

Question

I'm stuck on what I thought would be a simple thing to sort out. I have a custom table cell which contains a UITextView object. I want the text in this object to be grey. When I set the color in the interface builder it shows it as grey, but in the simulator it remains black.

Here's a run down of how it's set up:

1. The application is based on the master/detail template
2. I created a class that is a subclass of UITableViewCell
3. I added two properties to the class, an outlet for a UILabel and a UITextView
4. I altered the default prototype cell by adding a UITextView (it already has a UILabel)
5. I changed the class of the prototype cell to my custom cell class
6. I connected the UITextView and UILabel in the cell to the two outlets in my cell class

I updated the MasterViewController to populate my custom cell. When I run the simulator it all works fine in terms of the custom cells displaying the data.

As I mentioned before, the problem comes when I try to change the color of the text in the custom cell's UITextView. If I set it to Light Grey in the interface builder it has no effect in the simulator.

I've included the relevant code snippets and screenshots below. I'm not 100% sure what's relevant to the problem and what isn't, if you need to see something I haven't shown below just ask and i'll provide it.

** EDIT

When I log out the color property of my UITextView it outputs (null). See the MasterViewController.m code below.

Custom cell - NTFYNoteCell.h

#import <UIKit/UIKit.h>

@interface NTFYNoteCell : UITableViewCell

@property (weak, nonatomic) IBOutlet UILabel *titleLabel;
@property (weak, nonatomic) IBOutlet UITextView *descriptionText;

@end

Taken from the MasterViewController.m:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NTFYNoteCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"     forIndexPath:indexPath];

    NTFYNote *note = _notes[indexPath.row];

    cell.titleLabel.text = [note title];
    cell.descriptionText.text = [note shortDescription];

    NSLog(@"TEXTVIEW: %@", cell.descriptionText);
    NSLog(@"TEXT COLOR: %@", cell.descriptionText.textColor); // This outputs (null)

    return cell;
}

Debug out from above code:

2014-01-19 19:42:52.001 appname[5050:70b] TEXTVIEW: <UITextView: 0xa1bfe00; frame = (14 26; 273 57); text = 'This is a generic descrip...'; clipsToBounds = YES; autoresize = RM+BM; gestureRecognizers = <NSArray: 0x8be0530>; layer = <CALayer: 0x8be1fe0>; contentOffset: {0, 0}>

UITextView connected to the outlet in my Custom Cell:

Solution 1

After working through the problem a bit I went back to Google armed with the new information and found the following Stack Overflow question:

UITextView font is nil

Turns out if you don't check the 'Selectable' checkbox under the UITextView's attributes it doesn't respond to any font changes, including the color.

I checked this box and now it's all working as expected.

Thanks for your help!

Solution 2

If your UITextView contains text that is detected to be address/phone number/etc, you've got to set tintColor to change text colour of detected items, like this:

self.tvPhone.tintColor = [UIColor blueColor];

Solution 3

I wanted my UITextView "Read Only" but when I uncheck Editable and Selectable the behavior was not what I expected, sometimes the text color was not changing and sometimes the font was reset, so my solution was to check Editable and Selectable and uncheck User Interaction Enabled in interface builder

Solution 4

This worked for me. set selectable YES and set No after setting the color

cell.txtvComment.selectable = YES;
cell.txtvComment.textColor = [Globals getTextColor]; //set your UIColor
cell.txtvComment.text = comment.commentText;
cell.txtvComment.selectable = NO;

Please show the code where you are creating these cells.

I've added the part of the MasterViewController that sets the cell contents - i think this is the bit you asked for. Thanks!

[user2208214]

Use NSAttributedString. See: stackoverflow.com/questions/14287386/…

[Borzh]

There is a bug in iOS: changing text will change color also. You need to change the text color after changing the text, i.e. tv.text = @"asd"; tv.textColor = [UIColor whatever].

[jd182]

Thanks, i did actually try this. I tried it in two places, in the init method of my custom cell and in the method shown above where the cell contents is set. It didn't work in either place

[user2105505]

That's really strange. Did you use breakpoints or NSLogs to determine that this section of code is being called? I would use a series of NSLog(@"%@", cell.descriptionText.textColor) to see what the color is being set to and if it ever changes back to black.

[jd182]

Thanks, i've obviously messed something up somewhere if what i've done should work normally. Where should I put the NSLog code?

[jd182]

I've put the debug code into the method where the cell contents is set as you suggested. it's outputting (null) - any ideas why that might be?

[user2105505]

I added new suggestions to my answer.

[jd182]

Thanks, i've added the output from the console after also logging the UITextView. Weirdly the UITextView itself is an object, but it's color is null?

[Sebastian Boldt]

Worked for me. Thanks.

[cire.boroguies]

This saved me headache. Thanks.

[DefenestrationDay]

What a bizarre connection. I would never have thought of that.. Thanks

[nwkeeley]

Great find saved me a lot of headache

[Miguel Ribeiro]

Can this be a bug? After setting "selectable" it worked. Problem is, I don't want it as selectable

[limfinity]

@MiguelRibeiro you can easily reset it in code by using the selectable attribute of the text view.

[limfinity]

For me this was not a good solution, because it avoided the possibility to scroll in the text view.

[greg]

Anybody filed a bug on this yet?

This is the only solution that works on a project compiled for iOS 8.2 using Xcode 8 on a device running iOS 10. Thanks.
