Indent Second Line of UIlabel (Swift)

Indent second line of UILabel

Use an NSAttributedString for your label, and set the headIndent of its paragraph style:

NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
style.headIndent = 14;
NSDictionary *attributes = @{
    NSParagraphStyleAttributeName: style
};
NSAttributedString *richText = [[NSAttributedString alloc] initWithString:@"So this UILabel walks into a bar…" attributes:attributes];
self.narrowLabel.attributedText = richText;
self.wideLabel.attributedText = richText;

Result:

How Can I indent only first line of multiline UILabel in iOS?

@DavidCaunt suggestion worked for me. I am sharing code here.

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.firstLineHeadIndent = 50;

[attributedText addAttribute:NSParagraphStyleAttributeName value:style range:range];

[valueLabel setAttributedText:attributedText];

How to make UILabel display multiple lines in the Today Extension?

Increase the line limit number to 3 or more.
You can test the multiline wrapping by typing in the label yourself.
I know that setting it to '0' is suppose to work however when it comes to alerts and displays it does not always apply. I know that by giving it a number like '3' or '4' it is not dynamic, however, it will solve your problem with the notifications.

Alternatively you can use the "Autoshrink" feature, you can change it to minimum font size. By doing so, the application will shrink down the text to the font size you provided.
Some developers will also suggest checking the box, 'tighten letter spacing'

hope this helps.
