iphone - How to align UILabel text from bottom?

Question

How the UILabel can be aligned from bottom. Let say, my label can hold three line of text.If the input text is single line, then this line should come bottom of the label.Please refer the below image for better understanding. The orange area is the full frame of label.Currently it has one line and it is aligned center. So what I want is, it should always aligned bottom regardless of how many lines.

Please suggest your ideas.

Thank you.

Answer 1

Here are two ways of doing that...

1. First set numberOfLines to 0 and then use sizeToFit property of UILabel so your UILabel display with its contentSize.

yourLabel.numberOfLines = 0;

[yourLabel sizeToFit];

See more information from this link: Vertically align text within a UILabel

2. Another option is to take UITextField instead of UILabel and set userInteractionEnabled to NO like below...

[yourTextField setUserInteractionEnabled:NO];

and then set the contentVerticalAlignment property to bottom like below...

[yourTextField setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];

UPDATE

Also, with UITextField, we can't achieve multiple lines. So instead we can use UITextView and set its userInteractionEnabled to NO. Then, use the code below to make it bottom aligned.

CGFloat topCorrect = ([label bounds].size.height - [label contentSize].height);
topCorrect = (topCorrect <0.0 ? 0.0 : topCorrect);
label.contentOffset = (CGPoint){.x = 0, .y = -topCorrect};
