How to set a CGFloat to a UILabel's text property

I have a UILabel calle开发者_开发问答d optionsDisplayerBrushSizeLabel who's text property I want to set to a CGFloat: brushSizeVal. I understand that the text property needs to be a string but I don't know how to convert a CGFloat to an NSString.

You can try:

[NSString stringWithFormat: @"%.2f", myFloat];

Tray this in swift

var a = String (stringInterpolationSegment:myFloat)
