Unrecognized Selector Instance When Performing Segue - ios

When performing programatically performing a segue, the segue does work and the intended storyboard opens, but terminates immediately afterwards. The view controller/storyboard does work and shouldn't have any errors in the code as I've tested it individually, so I'm not entirely sure as to why it terminates. Any help would be appreciated.

The issue (discovered in the comments above) was that there was an action in the storyboard that was no longer hooked up to an action in code.
If anyone else in the future has a similar problem, look through the outlets menu for an outlet or action with the name provided in the console output. In this case, the action was named NameInputEditingDidEnd.

To expand on Nathan's answer, instead of randomly looking around, just cmd+shift+f the name of the outlet, in this case NameInputEditingDidEnd, and xcode will output the storyboard with the dangling outlet for you and center you to it.

Webview.Scrollview - Unable to add more than 126 Objects

My Application is getting crashed while scrolling UIWebview - I have used ILPDFKit for implementing interactive PDF - Editable Forms.App is getting crashed only if i am adding more than 126 Objects.
Here is code I am using (from ILPDFKit)
for (PDFWidgetAnnotationView *element in widgetAnnotationViews)
{
element.alpha = 0;
element.parentView = self;
[_pdfView.scrollView addSubview:element];
[_pdfView.scrollView bringSubviewToFront:element];
if ([element isKindOfClass:[PDFFormButtonField class]])
{
[(PDFFormButtonField*)element setButtonSuperview];
}
}
I have also raise Issue here
I have added some customview's in my webview.scrollview , so while scrolling webview my App is getting crashed. i have checked for all possible solutions i found on google/stackoverflow.
none of the delegate method of scrollview / webview called before this crash , as soon as i tried to scroll and app is getting crashed.
below is crash report.

Edit
1.How many subviews at most i can add into delegate of scrollview at a time?
2.I am only getting this crash if i am adding subviews more than 126?
Solution
Updating ILPDFKit worked for me.

"__NSCFString navigationBar" : unrecognized selector sent to instance

Alright Everyone,
I've got a real tough nut to crack. I am getting a very strange crash in my iOS app. During the sequence of closing a UIPopoverController by clicking off of it (on an iPad), this crash is occurring.
The really odd thing here is that it is a crash coming out of UIKit. I have filed a radar report for a very similar issue, but Apple marked it as closed and when asked, did not provide any further information than to say it was a duplicate of another issue (which I can not see).
Has anyone seen anything like this before?
EDIT 1: I can't figure out how to make the below a code block, the code block markup tool didn't do it. If anyone could point that out, that would be great :).
Thanks,
~Arash

You're accessing the CIImage property of an NSString (perhaps its id and you just accessed this property thinking that the id object was a UIImage). Search for CIImage in your class and make sure the object you're getting the property from is an actual UIImage.
If you want to find out where the actual line of code that is causing i suggest creating an exception breakpoint. You can do this by going to the breakpoints tab and adding one for all exceptions. This along with the log you should see what you are passing an invalid argument to.

iOS 7 app crashes on UITextField input

I'm trying to develop a questionnaire app where sometimes, a string must be inputted. In interface builder I have a scroll view, and in it a UITextField. But when I run it in the simulator, the app crashes when I try to input a simple string into it. The keyboard shows up, but as soon as I try to type something, I get a SIGARBT on the main function. The complete error message (don't mind the app name, it's just a simple test app that I made in a few minutes):

Is there some fundamental thing I forgot?
According to the stack trace, maybe you have initialized a NSString incorrectly. Please paste the relevant code.
This is a shot in the dark without seeing more of your code. Looking at the stacktrace, it seems like your code is misinterpreting your text input as a key command for some reason. It is trying to compare your input against a set of known commands and failing.
There are a few other things that might be related since you are running in the simulator. In the 'hardware' menu is 'simulate hardware keyboard' checked? What about 'IOS uses same layout as OSX'?
One last thing. If you really want people to be able to reproduce this issue, we need to see the UI code. If you right click on your storyboard file and select 'open as' there is an option to view the file as source code. For an app as simple as what you described, the text should be small enough that you can paste it here or host it somewhere and provide a link.

Thread 1 signal:SIGABRT Error IOS 7

I recently upgraded an app I created from iOS 6 to iOS 7 (and Xcode 4 to Xcode 5). I then tried to run the app, and the build said it succeeded, however the app crashed and directed me to this code and the error message:
int retVal = UIApplicationMain(argc, argv, nil, nil);
Thread 1 signal:SIGABRT
The console log is below in case that helps:
