Font Size resets in NSAttributedString

Question

Am adding an image to a NSAttributedString object so I can display them properly in a UITextView . So far, it works great. Only problem is, my Font size is 25 to match my image size but each time I add an image to the UITextView , the Font resets to some smaller size. I need to keep the font at 25 to match texts with the image size.

NSAttributedString has 3 constructors which take string , attributedString and string:attributes: .

Since I'm not using string, I can't set the attributes using the third constructor and the first 2 won't allow me to set attributes ( UIFont ). I therefore decided to set the Font size from Interface Builder and reset it each time I add an image to the `UITextField.

Am facing a problem here because each time I reset the font, the UITextView scrolls to the first line (assuming there is so much text, it has scrolled up). How do I set font size after adding image without the UITextView scrolling up automatically? Better still, is there a better way of doing this? Thanks.

NSMutableAttributed字符串可以尝试一些方法，包括在构造属性字符串之后跨范围设置属性。
