Calculate Size

[flodev03]

Hi honcheng,

first of all i want to thank you about this amazing label you give us.

I'm using RTLabel in my new app, everything is cool, great features, nice behavior...

I only have one thing that is making me lose my mind : how to calculate the size of the RTLabel depending on NSString ?

I use a CGConstraint to calculate the height of the label based on the RTLabel's text (NSString) but sometimes it is longer, sometimes shorter... can't have the real size.

How can i do this ?

thanks.

Ps : maybe you should add a donation button using paypal.

FWIW, I am having this problem as well. I need to show multiple RTLabels below each other in a view, but am unable to control the label placements because I cannot get an accurate height reading. At this point it looks like I have no choice but to abandon using RTLabel and instead using regular UILabels without the text formatting :-(

I get the height for RTLabel by calling [myRTLabel setNeedsDisplay] after setting the text then getting the height like so myRTLabel.optimumSize.height

I had the same issue, found solution after initialization of RTlLabel with frame of height 100.

RTLabel *yourLabel = [[RTLabel alloc] initWithFrame:CGRectMake(0,0,100,100)];
then assign text n get optimize height and update frame of yourLabel.
