[__NSCFType searchKeyword:]: unrecognized selector sent to instance 0x6d8eb80
objective-c, uncaught-exception, unrecognized-selector
Solution
You need to retain your `EventSearchViewController`, or keep a strong reference to it if you're using ARC. If you assign it to `view1` as a local variable, it's not going to be around any more when `searchKeyword:` gets called. (The error shows that its memory has been released and re-used for a different type of object.)
Problem
The following code is to add a subview to current view from storyboard: ``` EventSearchViewController* view1 = [self.storyboard instantiateViewControllerWithIdentifier:@"searchView"]; [view1 setBookingSystem:system]; [self.view addSubview:view1.view]; ``` In the view "view1", there is a textField. The following is a IBAction to the textField and the event is "Did end on exit". ``` -(IBAction)searchKeyword:(id *)sender { NSLog(@"searchKeyword"); } ``` The following is the error message. 2012-05-26 20:26:47.369 OnlineBooking[6607:f803] -[__NSCFType searchKeyword:]: unrecognized selector sent to instance 0x6d8eb80 2012-05-26 20:26:47.369 OnlineBooking[6607:f803] * WebKit discarded an uncaught exception in the webView:shouldInsertText:replacingDOMRange:givenAction: delegate: -[__NSCFType searchKeyword:]: unrecognized selector sent to instance 0x6d8eb80
