Determine padding and size of iOS UITextView

Question

Project

I am attempting to replicate the native iMessage app. I have used AcaniChat as a foundation.

I wanted automatic highlighting , so I modified the code to use UITextView instead of UILabel . I realize there are options such as FancyLabel and Three20 . However, UITextView does this natively.

Problem

I am having a difficult time getting the padding/size of UITextView right. I updated the contentInset property based on suggestions in other answers .

msgText.contentInset = UIEdgeInsetsMake(-11.0f, -8.0f, 0.0f, -8.0f);

I am also determining the size with the following:

CGSize size = [[(Message *)object text] sizeWithFont:[UIFont systemFontOfSize:kMessageFontSize]
                                   constrainedToSize:CGSizeMake(kMessageTextWidth, CGFLOAT_MAX)
                                       lineBreakMode:UILineBreakModeWordWrap];

Nonetheless, some text is still being cut off (see image below). Notably the phone number and email address (right) as well as the "that cut off?" (left)

I have verified this is not due to the dataDetectorsTypes property.

Question

I can solve this by increasing the CGRect of the UITextView . But I want to better understand the affects of margin/padding and size of the UITextView . I don't want to arbitrarily increase the size by 20.0f to make it work .

As such, what is the code or combination of code that I can reliably set the size of the message bubble?

Answer 1

Not a solution for your problems with UITextView but ... I had similar problems and decided to give core text a chance. You have simply more control about what is happening. You could have your string attributed using regex statements to make links/emails/phone numbers visible and have furthermore the chance to use even other fonts.
