Somewhere you're using UIImage where it should be UIImageView.

I have an XIB that I present as a modal view. I have a button that calls the following -
(IBAction)dismissVC:(id)sender {
[self.parentViewController dismissModalViewControllerAnimated: YES];
}
When I press it the app crashes with this notice -
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController dismissVC:]: unrecognized selector sent to instance 0x8379350'
The thing I noticed is that I have a ViewController.xib file and I have this MapView.xib that is a modal VC I want to dismiss. It's presented from a ViewController.xib
What could be the possible issue? I've hooked up all the actions and the File Onwer thing as well.
Thanks in advance!
Try this:
unrecognized selector sent to instance
that might be your solution.
I'm trying to make a gesture recognizer in my app with Interface Builder.
I drag and drop my gesture on my view (it is a UIView which contains UILabel, UIImage and UITextView, all made in Interface Builder).
But when I compile and run, my app crashes and I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString setView:]: unrecognized selector sent to instance 0x80a5fd0'
I don't understand the reason.
Can someone help me?
For some reason I cannot figure out I have an IBAction code wired up to fire on the touchupinside for a UIButton on a view using Interface Builder. Simple stuff right?? Well it works fine in my iphone version but for some reason I keep getting the following error when I click on the button in the iPad even though I have it wired up properly. IB has the the correct class name for files owner, it's wired to the action. I've checked and double checked my connections, rewired them from scratch, cleaned classes, deleted the app from the simulator and googled to the end of the internets.
Why would this be any different between ipad and iphone version? Can someone please help me before I go insane on something that should be working but just refuses to work???? Even weirder it seems whatever I try to wire up to an action is throwing a similar error. I'm starting to think Interface Builder is just crazy or something.

UIViewController doesn't respond to doClick: which is what you are seeing here.
In the nib file for your view, have you set the "File's Owner" to the class that you inherit from UIViewController and contains the doClick: method?

Hi, i am using Core-plot . but when i declare the normal UIView as CPLayerHostingView,how can i handle drawRect of that view , i cant give another custom UIview name and write code in drawRect of that view?please any help to handle drawRect of CPLayerHostingView?
Put the CPLayerHostingView inside another UIView. The background from your custom UIView will show through if you use transparent fills in the graph.

I have a Tab Bar application with four new headers, implementation and interface files, and added those as the sources in IB. They were in this format: FirstView.h/m/xib, SecondView.h/m/xib.
I then had files for First-, Second-, Third- and FourthView.
There was also a file there called FirstViewController. I did not touch this, I just deleted it because I wasn't going to need it.
I then laid out my interface for the first view (FirstView.h/m/xib) in IB. It had an image on the top, label under and a UITableView under that.
I sat up the correct connections (delegations and datasource for the tableview) in my FirstView.h/m file, and pressed Build. It seemed to build without errors, so I pressed Build and Go.
The Simulator popped up, installed the app and crashed. (Error message:Terminating app due to uncaught exception).
Complete error message:
2010-02-06 21:50:54.733 Mudo[52439:207] *** -[FirstViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x39101a0

I asked about this in another question, got an answer, and that fixed it:
It was obviously looking for code in the FirstViewController.h/m-file, although I did not do anything to make it look for code there.
I fixed this by adding two interfaces and implementations in my FirstView.h/m file. (FirstView and FirstViewController)
When I ran the app then, the table view and tab bar came up on the screen, but my image and label did NOT.
I don't have any idea of why it was looking for the code in FirstViewController instead of FirstView... I have the correct connections in IB, too..
A tableview is trying to query its data source for the number of rows it should display. If you've connected the tableview's datasource outlet to an instance of your FirstViewController class, then you need to implement -tableView:numberOfRowsInSection: in that class.
