There are 2 things you could be doing wrong here:

1) UITextView doesn't necessarily call that method on init; It might be calling -initWithFrame: , -initWithFrame:font: or -initWithFrame:webView: (or even just -init, and be setting the frame later on) . You should hook all cases and see if you get any results and on which one of them.

%hook UITextView
-(id)initWithFrame:(CGRect)frame
{
    %log; // conveniently NSLogs self,selector,arguments
    return %orig;
}
-(id)initWithFrame:(CGRect)frame font:(UIFont *)font
{
    %log; 
    return %orig;
}
-(id)initWithFrame:(CGRect)frame webView:(UIWebView *)webView
{
    %log; 
    return %orig;
}
%end

2) Make sure the process you're hooking onto is the one calling the method. If your project's plist filters "com.apple.springboard" and you're testing this into another app, e.g. "com.apple.mobilesafari", it won't work.

  • and this kind of problem i am already facing for hooking uikeyboard, if its working on only for spring board but in inner app like notes, or in other iOS app its not working – Raj Oct 17 '12 at 05:27
  • If you want to hook every UITextView, you should filter "com.apple.UIKit" in your dylib's plist instead. – Elias Limneos Oct 17 '12 at 21:31
