I am currently using
- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(UILineBreakMode)lineBreakMode
to get the size of an NSString. However, when that string includes emojis, it seems to calculate the size for the literal unicode character rather than taking into account the size of the emoji itself, rendering the returned size incorrect.
How do I correctly get the size of the string with emoji characters, as it will appear in a uilabel?
The NSString is not presenting the emoji, it's representing a string, so the sizeWithFont will only account for the string.
I would use:
or
Bare in mind that
sizeToFit
calls thesizeThatFits:
method, so in terms of just setting the label to the right height, sizeThatFits: is quicker, and much easier on the eye.I struggled with this same thing for a while, attempting multiple solutions including the accepted answer, which did not work for me. I solved this by creating an NSAttributed String with the text, then using the NSAttributedString method boundingRectWithSize:options:context: to get the size of the string.
