Errors Changing Data in a TableView Objective C
ios,objective-c,uitableview,unrecognized-selector
No matter how you declared dwarves, it is an NSArray and not an NSMutableArray. Therefore addObject crashes. I believe the combination of "copy" property and mutable type doesn't do what you think it should do. Better make "dwarves" just a normal "strong" property, but initialise self.dwarves = [@[@1.5,@2.,@2.5,@3.,@3.5,@4.,@4.5,@5.,@5.5,@6.,@6.5,@7.] mutableCopy]; ...
unrecognized selector sent to instance in ViewController using Notifications
ios,swift,unrecognized-selector
The name of the selector should be "naamInModelChangedHandler:". Note the : since naamInModelChangedHandler takes an NSNotification as an argument. Therefore, you should add the observer like so: NSNotificationCenter.defaultCenter().addObserver( self, selector: "naamInModelChangedHandler:", name: "NAAM_CHANGED", object: model) ...
Getting error [UIImage length]: unrecognized selector
objective-c,runtime-error,unrecognized-selector
There's problem in your filltheLetterArray method, you're replacing objects in oneletter array, you're storing images (UIImages from randomImage method)directly into it, and this method crashing the app, setImagesInArray, this line image4.image = [UIImage imageNamed:[oneletter objectAtIndex:r]]; as you're assigning image file name (as NSString) but actually its containing UIImage objects.
“unrecognized selector sent to instance” at performSegueWithIdentifier
ios,objective-c,uiviewcontroller,segue,unrecognized-selector
I've seen this error before when you've set the class of a view (probably your controller's main view) to a class that's not a subclass of UIView. Make sure that when you set the custom class of your controller (in the storyboard) that you've set it on the controller, not...
Cannot use string as booleans
ios,objective-c,unrecognized-selector
[loggedUser isStaff] seems to be an NSNumber / Boolean object yet you are trying to compare it to an NSString. Booleans and NSNUmbers do not have an isEqualToString method. If you want to compare whether the user isStaff, you should try: if ([[loggedUser isStaff] boolValue]) { [self performSegueWithIdentifier:@"staffLogin" sender:self]; }...
How to achieve infinite scrolling backgrounds in swift
I'm not an expert on swift, but it seems like this is not working out: You are declaring moveBackground as a function inside levelClicked, but on your timer you are referencing self as target. The Class itself has no method moveBackground. It's only visible inside your function levelClicked. Try to...
UIAlertController doesn't display and crashes/freezes app in iOS8

Passing an Object between Table View Controller and it's Detail View Controller, getting NSInvalidArgumentException error
ios,objective-c,unrecognized-selector
It looks like you must have set up currentContainer as a IBOutlet at some point (but you're not doing that now), because in the storyboard, I see currentContainer connected as an outlet to the same label that containerName is hooked up to. Delete that connection, and I think it should...
App crashes when passing an argument to a method in NSTimer
ios,objective-c,selector,nstimer,unrecognized-selector
The argument of timeCycle: is NSTimer not UILabel. Also why you need to pass the label ? It's a property right ? So change your method like: - (void)viewDidLoad { [super viewDidLoad]; timer = [NSTimer scheduledTimerWithTimeInterval:animationDuration target:self selector:@selector(timeCycle:) userInfo:nil repeats:YES]; } - (void)timeCycle:(NSTimer *)timer { time++; if (time == 10)...
unrecognized selector sent to instance 0x7ff971e1f920
ios,objective-c,uitableview,unrecognized-selector
Presumably you've defined a custom cell subclass with a configure: method. Your subclass isn't being used - that message means you're calling the method on a plain UITableViewCell. The most common cause of this is forgetting to set the cell class in the storyboard. Otherwise, you'll need to show how...
JSON parsing unrecognized selector sent to instance 0x8f3ab10

It should be NSDictionary *getVersion = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil]; NSString *currentVersion = [getVersion objectForKey:@"version"]; or with new syntax NSString *currentVersion = getVersion[@"version"]; because objectAtIndex means you are accessing an array but you only have a json object...

I think your TableView may be getting released after you create it and the method ends.

Object for key kMotivo is NSArray in your code. You are assigning it to NSString property and afterward to UILabel text property. UILabel tries to call length on NSArray and crash with an exception. Something like following will work: NSArray *motives = [reasonsDictionary objectForKey:kMotivo]; if (motives != nil && motives.count...
Swift Selector with default argument
The thing is that the parameter is not up to you. It is always the button (the "sender"), and that is the only thing it can be. In other words, if you want this function to have a parameter, then by all means you will need to set your selector...
App crashes when passing data from one ViewController to another

How do I center a UIImage inside a UITableView cell?
ios,objective-c,uitableview,unrecognized-selector
You need to subclass UITableViewCell and reposition the frame of the built in imageView in layoutSubviews to achieve what you want to do.

You are setting the utilizationManager instance in your UtilizationVC, but you don't have any property in that class. For this reason the app crashes.

UINavigationController *navController = (UINavigationController *) self.window.rootViewController; MasterViewController *masterController = [navController.viewControllers objectAtIndex:0]; The problem is here.

You then request the first view controller held by this supposed-but-not-actual navigation controller, which...
