Answer 1

In Swift:

testLabel = UILabel(frame: CGRectMake(6, 3, 262, 20))
testLabel.text = test
testLabel.numberOfLines = 0
testLabel.sizeToFit()

In Objective C

UILabel *testLabel = [[UILabel alloc] initWithFrame: CGRectMake(6, 3, 262, 20)]];
testLabel.text = test;
testLabel.numberOfLines = 0;
[testLabel sizeToFit];
