UILabel with autolayout in iOS.
We all know that
UILabels have intrinsic content size which allows them to adjust their height based on the content size. Which means you can add
UILabelto your views, set
numberOfLinesto zero, set appropriate height constraint and see in action that label adjust its height to accommodate the content.
Here's how to do it,
UILabel *label = [[UILabel alloc] init]; label.numberOfLines = 0; label.textAlignment = NSTextAlignmentCenter; label.text = @"This is very long text\nAnd this is second line\nAll Created with Autolayout\nAnd now this is last line"; label.backgroundColor = [UIColor lightGrayColor]; [self.view addSubview:label]; [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-10-[lab]-10-|" options:kNilOptions metrics:nil views:NSDictionaryOfVariableBindings (lab)]]; [autolayoutContentView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-44-[lab(>=10)]" options:kNilOptions metrics:nil views:NSDictionaryOfVariableBindings (lab)]];
Here's what you can see, we have specified that
UILabel height should be
>=10 which allows it to stretch as content grows.
