Get Rid of Line Breaks UITextView - ios

For the past few hours I have been trying to get rid of all the visible line breaks that my UITextView is showing. So I thought it would be as simple as running this code:
NSString *trimmedString = [textView.text stringByReplacingOccurrencesOfString:#"\n" withString:#""];
[textView setText:trimmedString];
However, it seems like nothing changes after executing that. The textView text is in fact being set to trimmedString but the line breaks are still visible like shown in the picture below.
How would I properly fix this so I can have the text shown in the image (as an example), be without line breaks?

I just put your example code in the viewDidLoad of my UIViewController and totally saw the expected result. Here is one screenshot without your code snippet:
And here is a screenshot with the code snippet:
You can see that the line breaks were replaced. Did you connected your UITextView Outlet correctly ?

I fixed it with this code:
NSString *trimmedString = [textView.text stringByReplacingOccurrencesOfString:#"\r\n" withString:#" "];
[textView setText:trimmedString];

"ԅ" causing iOS app crash

I find that if I set UILabel's text to "ԅ", it crashes without further information. It didn't hit the "All Exception" breakpoint.
self.label.text = #"ԅԅ";
How do I get rid of this crash? Thank you in advance!
By the way, I found this problem due to an emoticon "ԅ(¯﹃¯ԅ)", which kind of describes what I'm feeling right now.
Do not pass directly a Unicode character to NSString initialisation, instead use the character's Unicode code-point representation. In case of this character, it'd be #"\u504".
try this:
NSData *strd = [text dataUsingEncoding:NSUTF16StringEncoding];
NSString *newStr = [[NSString alloc] initWithData:strd encoding:NSUTF16StringEncoding];

Textview will not add text on load

I've been spending hours trying to get my textview to load with text from a string when loading but it always appears blank but when I do it through button action it works fine.
Is this a known issue or is there even a solution?
Here is the code. NSLog does show the string contents.
Variables *GetVariables = [Variables SharedInstance];
NSString *Text = GetVariables.FileText;
NSLog(#"%#", Text);
_MyTextField.text = Text;

Ends of lines getting truncated on iPhone ( EDIT : end of line justification)

When I use a .txt file in my app (even when I fix it up as much as I can) The lines at the end get truncated. I want the text to reach the end of the line (all the way to the right side of the screen, just like the first line) . Should I use another type of file? If so, which? and if not, how do I get the words to reach the end of the line?
Thanks
p.s. cleantxt doesnt fix the problem
I want it to look like this
If I interpret your question correctly (via your example), this is not a question of truncation but a question of justification. You want "full justification" i.e. text stretching from left to right insets so the text appears as a rectangular block of text.
If yes and you are using a UITextView then:
For iOS 6 and earlier
UITextView *textView = #""; // replace with property representing the text from your .txt file
textView.textAlignment = NSTextAlignmentJustified;
For iOS 7+ (above is deprecated)
You unfortunately need to either use CoreText or a UIWebView.
See this post Justified Alignment in UITextView
Do you get the same result using this code?
NSString *fileName = #"impressum.txt";
NSURL *url = [[NSBundle mainBundle] URLForResource:[fileName stringByDeletingPathExtension] withExtension:[fileName pathExtension]];
NSError *error;
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithFileURL:url
options:#{NSDocumentTypeDocumentAttribute:NSPlainTextDocumentType}
documentAttributes:nil
error:&error];
CGRect paragraphRect = [attributedString boundingRectWithSize:CGSizeMake(_textLabel.frame.size.width), CGFLOAT_MAX)
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
context:nil];
CGRect frame = _textLabel.frame;
frame.size.height = paragraphRect.size.height;
_textLabel.frame = frame;
[_textLabel setAttributedText:attributedString];

iOS: Column formatting for NSString not working in UITextView?

I'm working on an iPad app and I need to be able to format some output on the screen in a columnar format. This was similar to my question:
How can I use the \t [tab] operator to format a NSString in columns?
and I used that solution, unfortunately I'm not seeing the same results. My code is as follows:
NSString* titleColumn = [[NSString stringWithFormat:#"%#", displayName] stringByPaddingToLength:25 withString:#" " startingAtIndex:0];
NSString* serializedValue = [[NSMutableString alloc] init];
NSString* valueAsString = [NSString stringWithFormat:#"%.03f", value];
serializedValue = [serializedValue stringByAppendingFormat:#"%#%#", titleColumn, valueAsString];
When logging the items in the console, they are properly aligned, however, when plugging them into a UITextView, they are misaligned. This is how I'm sticking them in the text view:
NSMutableString* displayString = [[NSMutableString alloc] initWithString:#""];
for (NSString* entry in textToDisplay)
{
NSLog(#"%#", entry);
[displayString appendString:entry];
[displayString appendString:#"\n"];
}
[self.fTextPanel setText:displayString];
Any ideas on what I'm doing wrong?
EDIT:
In the log, it looks like this:
Inclination 0.000
Version 0.000
Inferior/Superior 0.000
Anterior/Posterior 0.500
And the UITextView version looks like this: http://imgur.com/vrUzybP,OYxGVd8
The reason for misaligned is the different width for each character. The best way for displaying this type of information is by using UITableView, You can use title and subTitle field for displaying or you can design a custom UITableView.
the reason is because when drawing charachters (glymphs), each character will have different widths,i.e character small c and big C will take different widths for drawing , so it wont work. Even though there are two strings with equal lengths but different characters, the drawing text will have different widths.
What i would suggest you for this is to have two textViews side by side, render titles in one textVIew and values in the next TextView.
If the number of titles is large and if you enable scrolling in textVIews, use delegate Methods of UIScrollView, and when scrollHappens in either of them, set the contentOffset of the other to make it look like single TextView.
Hope this helps.

Replace lines of text in iOS

I am needing to replace a line of text in code on my iOS app, however the lines that need to be replaced in the particular NSString will be different for different entries on the XML that is being parsed.
For example, I need to replace 129727-the-cave.mp3 with 129727.jpg.
However, I can't just tell it to replace -the-cave.mp3, because some instances of the string will have a different number and title of mp3. I think the next line is:
129838-my-song.mp3.
So, basically, I need a way to find everything from the first hyphen through mp3 and replace it, no matter what the text is?
Try this:
NSString *original = #"129727-the-cave.mp3";
NSString *sub = [original substringToIndex:[original rangeOfString:#"-"].location];
NSString *finalString = [sub stringByAppendingString:#".jpg"];
NSLog(#"finalString: %#", finalString);
