Replacement for deprecated sizeWithFont: in iOS 7?

Question

In iOS 7, sizeWithFont: is now deprecated. How do I now pass in the UIFont object into the replacement method sizeWithAttributes:?

Answer 1

You can still use sizeWithFont. but, in iOS >= 7.0 method cause crashing if the string contains leading and trailing spaces or end lines \n.

Trimming text before using it

label.text = [label.text stringByTrimmingCharactersInSet:
             [NSCharacterSet whitespaceAndNewlineCharacterSet]];

That's also may apply to sizeWithAttributes and [label sizeToFit].

also, whenever you have nsstringdrawingtextstorage message sent to deallocated instance in iOS 7.0 device it deals with this.
