"Unrecognized selector sent to instance" error
(3 answers)
Closed 7 years ago.
I've run into an annoying issue when trying to segue to a Pages View Controller from my initial UIViewController. My initial UIViewController, among other things, includes a UITextField. Everytime I attempt to segue out of my initial UIViewController after I've used the UITextField at all, the app crashes with the error below. If I don't interact with the UITextField I seem to be able to use segues at will. From reading other posts I'm lead to believe there are some resources being used by the UITextField that I'm not properly releasing, but after trying numerous longshot attempts at fixing it, I'm left out of ideas/knowledge.

Last bit of code before the segue is called:
#IBAction func learnButtonPressed(sender: UIButton) {
view.endEditing(true)
textInputFieldOutlet.resignFirstResponder()
textFieldShouldEndEditing(textInputFieldOutlet)
performSegueWithIdentifier("LearnPagesSegue", sender: nil)
}
I can't find any methods or objects in my code named -textFieldCancel, and the only other UITextField I can think of would be in the included CardIO library, which doesn't seem to be the suspect.
I'm using Xcode 6.3.2 and the latest version of Swift.
Any help or gentle nudges are appreciated.
Thanks!
Check that there isn't an old connection from your button by right clicking on it in the storyboard and examining the outlets in the list. You may have an old connection that you forgot to eliminate.

The app crashes in simulator when one item is pressed on the slide out menu (created with table view), I've tried deleting connections between UI and IB and remaking them incase this is the issue, but it hasn't solved it.
This is the error code that comes out:

According to the error, it most probably is that one of your views is connected to an outlet named AnnualInterestInput that was deleted from the class.
If by deleting all the outlets and reconnecting them to the view controller didn't work it out, then it may be due to a wrong class in the xib.
This means that you have set a wrong class in the xib or storyboard and it's not able to found the key. If the class is still correct, check if the module is correct!
This line is what gives me a hint that this could be the problem:

I implement segue and add the animation and it works.
I am using the following code:
#IBAction func popToRoot(sender:UIBarButtonItem){
navigationController.popToViewController(foodforteethViewController(), animated: false)
}
This function is linked with a custom back button and the h file is linked in the objective-c/swift bridging file. The issue with this is that I get an error as below:

What's going wrong?
you can not pop a view controller which is not in NavigationController stack.You should pop like this
if you want pop to rootViewController than there is direct method use this
#IBAction func popToRoot(sender:UIBarButtonItem){
self.navigationController.popToRootViewControllerAnimated(false)
}
Another way to go back to a specific view controller would be to use unwind segues:
What are Unwind segues for and how do you use them?
I downloaded the OHGridView hoping that it was the answer to all my problems.
https://github.com/AliSoftware/OHGridView
I did all that it said to do (add the class files, add the code, and change a few other things).
I went to build it and it crashed. I realized the lines of code why it was crashing:
((OHGridView *)self.view).rowHeight = 100;
((OHGridView *)self.view).columnsCount = 2;
Error from Console:

I removed them and it loaded fine but I didn't see any content.
Please help,
thanks.
I did a clone of the repository just now and then did a build and run of his example project without making any changes to the code. It ran without any warnings or errors.
You'll need to check your code wherever you made changes.
update after your comment
Unrecognized Selector often means that you have a capitalization error or that your code isn't the kind of object that you think it is.
For example: I can get almost the same error that you get if I try to call the setRowHeight: directly against a OHGridView object instead of the view property of the object, like this
((OHGridView*)self).rowHeight = 100;
((OHGridView*)self).columnsCount = 2;
So, I would check your code to make sure that your object is an OHGridView and that you are setting the rowHeight property of the view of the OHGridView.
I am developing an iPad application with SDK4.2. I have a very strange error when touching any textField in my application. The first time I touch, the keyboard is shown, but when a second touch is done in the object I obtain following trace.
And it occurs also in any TextField shown in a HTML page with a UIWebView object.
Any ideas?
I am really confused with this.. Thanks in advance!

terminate called after throwing an instance of 'NSException'
Look carefully what exception was about. It said "reason: 'Invalid parameter not satisfying: color'", somewhere in your code, you provide wrong parameter that is supposed to be valid colors. Apparently, it seems like you use UIButton with label and set its color but not valid.
My guess is that you have some object going away somewhere, and that object contains the "color" value.
Most likely you received an autoreleased value from some call and did not retain it, so it went "poof" when the UI came up for air.
