iphone sdk - problem pasting into current text location
- by norskben
Hi guys
I'm trying to paste text right into where the cursor currently is. I have been trying to do what it says at:
- http://dev.ragfield.com/2009/09/insert-text-at-current-cursor-location.html
The main deal is that I can't just go textbox1.text (etc) because the textfield is in the middle of a custom cell. I want to just have some text added to where the cursor is (when I press a custom key on a keyboard).
-I just want to paste a decimal into the textbox...
The error I get is:
2010-05-15 22:37:20.797 PageControl[37962:207] * -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10
2010-05-15 22:37:20.797 PageControl[37962:207] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10'
Note: I have access to the textfield tag (if that helps?)
I'm a little past the beginner stage in objective-c, but still not great. My code is currently below, and at https://gist.github.com/d634329e5ddf52945989
Thanks all.

switch (tagClicked) {

//savedAmount.text = [savedAmount.text stringByAppendingString:@"."];

}
-(void)textFieldDidBeginEditing:(UITextField *)textfield{

@implementation UIResponder(UIResponderInsertTextAdditions)

// the only one @selector(paste:) will use.
UIPasteboard* generalPasteboard = [UIPasteboard generalPasteboard];
// Save a copy of the system pasteboard's items
// so we can restore them later.
NSArray* items = [generalPasteboard.items copy];
// Set the contents of the system pasteboard
// to the text we wish to insert.
generalPasteboard.string = text;
// Tell this responder to paste the contents of the
// system pasteboard at the current cursor location.
[self paste: self];
// Restore the system pasteboard to its original items.
generalPasteboard.items = items;
// Free the items array we copied earlier.
[items release];
}
