You can also create a String extension and reuse it with any text string.. You can do it in the following way:
create the extension:
extension String {
func maxLength(length: Int) -> String {
var str = self
let nsString = str as NSString
if nsString.length >= length {
str = nsString.substring(with:
NSRange(
location: 0,
length: nsString.length > length ? length : nsString.length)
)
}
return str
}
}
you can use the extension in the following way:
label.text = "This is a Very Long Label".maxLength(length: 10)
the previous code was tested in Swift 5.0

If you want to limit the UILabel to just 10 characters then
you just have to assign it with a text with length of 10.
You can use NSString and NSRange to extract the text you need.
let str = "This is a Very Long Label"
let nsString = str as NSString
if nsString.length >= 10
{
label.text = nsString.substringWithRange(NSRange(location: 0, length: nsString.length > 10 ? 10 : nsString.length))
}

Of course this code will crash if
str has less than 10 characters in it to start with.Check out this answer: https://stackoverflow.com/a/39677331/2548473
My version is (Swift 5+):
extension String {
func shorted(to symbols: Int) -> String {
guard self.count > symbols else {
return self
}
return self.prefix(symbols) + " ..."
}
}
UILabel?
