Question

I want to use CGAffineTransformMakeRotation for NSString, how can i do it? Its working with labels and i need for my function only strings.

Answer 1

CGAffineTransformMakeRotation is used to set the transform property of a UIView, NSString is not a UIView so it cant be transformed, it has not concept of rotation

you need to do this at display time with a UILabel

an example:

NSString *myString = @"whatever";
CGAffineTransform stringTransform = CGAffineTransformMakeRotation(M_PI / 2.0f);

UILabel *stringLabel = [[UILabel alloc] initWithFrame:labelFrame];
stringLabel.transform = stringTransform;
stringLabel.text = myString;

[self.view addSubview:stringLabel];
