How to add line breaks in Text View

[cpcdev]

Hi,

I added a simple text view object to one of my views and I'm having trouble adding line breaks. Basically, I want to put space in between each of the paragraphs in the text view but when I hit enter on my keyboard, instead of going to the next line it takes me out of the editing mode. I'm running a hackintosh so I don't have the same return key as mac users.. is this why? Thanks for the help

I don't know how you can add it via interface builder but what I usually do is just make it an IBOutlet then add this on the viewDidLoad.

textView.text = [NSString stringWithFormat:@"Line 1\nLine 2\nLine 3\n"];

This would show as:

Line 1
Line 2
Line 3

Essentially, \n is a line break.

Try with return key on simulator/device keyboard, if it is working fine, then u need not bother about inputs from desktop keyboard.

Thanks, I tried this and I get the app to build and launch successfully but when I click on the tab bar item to load the view it crashes and I get this error in console:

"'NSUnknownKeyException', reason: '[<UIViewController 0x5b594a0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key textview.'"

Here's what I added in the .h file:

IBOutlet UITextView *textview;

@property (nonatomic, retain) UITextView *textview;

for the .m file:

@synthesize textview;

void view did load method:

	
textview.text=[NSString stringWithFormat:@"Hi how are you \n good how are you? \n great, thanks\n"];

Then I created a XIB file for this, added a text view object to the XIB, then linked up the text view with the IBOutlet and the view with the view in the document folder.

What am I doing wrong? Thanks for your help

I just tested it and it worked fine >.< Try remove the properties for the IBOutlet? Here is how I have mine setup and working:

.h

IBOutlet UITextView *textView;

.m

-(void)viewDidLoad {
	
	textView.text = [NSString stringWithFormat:@"Hello\nHi\nHow are you?"];
	
}

I don't have the properties in mine, try it without them? You can try this in a new view controller to get the hang of it without the tab-bar then implement it with the tab bar.

Ok great, I got it to work. It was actually a problem with my tab bar item not being wired up to the controller class.

How can I add bold font to the text or change the color in this case?

Thnx again
