Awesome library in fact

i am using this control to render some articles and some of them are thousands of lines, its taking almost 30 seconds to prepare and render a SSTextView with 10 thousands lines with font size of 20

Please tell me how can i resolve this issue

thanks

If you are going to render this much lines, it will definitely take time as multiple font tables are to be applied on the text. Moreover arm architecture is much slower than x86_x64, therefore more time is consumed in processing on device.

thanks Tayyab for quick reply, Would you suggest any solution for this problem in current implementation. i have compared the results with UITextView, and UITextView is surprisingly fast.

SheenFigure is a remarkable effort by Tayyab. However, if your aim is just to display text in popular Urdu fonts, you can use core text on iOS and OS X.

Actually UITextView does not do shaping, that's why it is faster. As of know the only way for you is to either reduce the text or divide it into several portions and let the users read those portions like pages.

However, if you provide me the sample file I can analyze the most slow process and think of ways to make it work faster.
