Variable height using constraints
suggest changeYou can make an UILabel
with a dynamic height using auto layout.
You need to set the numberOfLines
to zero (0), and add a minimal height by setting up a constraints with a relation of type .GreaterThanOrEqual
on the .Height
attribute
Swift
label.numberOfLines = 0
let heightConstraint = NSLayoutConstraint(
item: label,
attribute: .Height,
relatedBy: .GreaterThanOrEqual,
toItem: nil,
attribute: .NotAnAttribute,
multiplier: 0,
constant: 20
)
label.addConstraint(heightConstraint)
Swift
label.numberOfLines = 0
label.translatesAutoresizingMaskIntoConstraints = false
label.heightAnchor.constraintGreaterThanOrEqualToConstant(20).active = true
