iPhone UILabel - non breaking space - ios

Question

Is there a way to use non breaking spaces in UILabel text?
For example, I have label with 2 lines and line breaking mode set to word wrap. The content for this label is read from database, where it's stored as a string. Now sometimes my text in label looks like that:
lorem ipsum some text
1
but I want to display it like that:
lorem ipsum some
text 1
so basicly, I need to force non breaking space between 'text' and '1'.
I've found some solution here, but I think it could work when the text is entered in source code file. In my case the text is in database.
Any suggestions?

Answer 1

Use the no-break space (\u00a0) ex: #"hello**\u00a0**world!"
post.text = [postText stringByAppendingString: #"1\u00a0hour\u00a0ago."];
U+00A0 / no-break space / Common Separator, space

For Swift:
let sentence = "Barcelona, Real Madryt, Juventus Turyn, Bayern Monachium"
let sentencewithnbsp = String(map(sentence.generate()) {
$0 == " " ? "\u{00a0}" : $0
})

In Swift 4 I had to use all caps: \U00A0
Example:
lorem ipsum some\U00A0text 1
Update Feb 2020 from the comments. Thanks to #corban:
In the Localizable.strings file it still needs to be \U00A0 - in code
you have to use \u{00a0}

If you want to get this to work in a .strings file, you can type OPTION + SPACE instead of a regular space.
.strings files are usually UTF-8 encoded, so if you open it in Hex view, you will see "C2 A0" in place of the special space character.

Answer 5

In Inspector set number of lines for Label as 3 or 4 What ever you require Then the Content will be displayed in multiple lines.

You may need to implement a custom word-wrapping function.
// pseudo-code
instring;
get len(instring)
if len > textedit.width*charFontSize
for (textedit.width*charFontSize ) // cycle through string
insert `\n` into inString at shortest whitespace
or something like that.

I don't think there's a simple way to do this with UILabel. Of course one way to achieve the same effect is to manually insert a "\n" before "text" in your example. Another option is to use a UIWebView with static HTML instead of the UILabel, so you can use an actual &nbsp.

Here's a Swift extension to fix an orphan in a string by replacing the last space with a non-breaking space:
extension String {
var replacingLastSpace: String {
if let lastSpace = range(of: " ", options: .backwards, locale: .current) {
return replacingCharacters(in: lastSpace, with: "\u{00a0}")
}
return self
}
}
Although note as of iOS 11, UILabels solve this problem automatically.

If this is not going to happen often, you can do this:
NSString *string = #"lorem ipsum some \ntext 1";
label.text = string;
You can dynamically generate where you put the \n using character counts, word counts etc...
