I am getting an interesting warning at build time (iPhone simulator) that gives the following:
EditView.xib:35:0 UITextView does not support data detectors w
I was seeing this warning as well. Here's how I fixed it:
In the xib file in Interface Builder, select your text view, and bring up the attributes inspector. Make sure that "Detects Phone numbers" and "Detects Links" are both UNCHECKED.
I had "Detects Links" checked, and turns out that's what was causing the warning. Basically, if the textview is editable, you don't want these auto-detect features turned on.
