How would I set the Line Height or Line Spacing in an NSTextView
(i.e. how tall each line is, or how much space is between each line)?
leave the answer in case someone need:
NSMutableParagraphStyle * myStyle = [[NSMutableParagraphStyle alloc] init];
[myStyle setLineSpacing:10.0];
[myTextView setDefaultParagraphStyle:myStyle];
