Why am I getting invalidArgument exception while running unit test? - objective-c

Inside my Table view controller I have following method
-(BOOL)isValidCoordinate:(CLLocationCoordinate2D)coordinate
{
//This is just to make sure exception is always thrown a cut down version of method
[NSException raise:#"Invalid longitude value" format:#"Longitude of %d is invalid", coordinate.longitude];
return TRUE;
}
I am running a unit test against it and I it failing giving following exception

The error is that you did declare newView2 as a TableViewController not a MapViewController (which has that method), change:
TableViewController *newView2 =[[MapViewController alloc] init];
with:
MapViewController *newView2 =[[MapViewController alloc] init];
anyway I would call the variable newViewController rather than newView2 :P

Application Crash on ios11 & Xcode 9: while adding [self addChildViewController:]

While adding child viewcontroller, I am getting following crash,
Here NavigationViewController is extended from UIViewController.
This error is coming when I upgraded to Xcode 9, working successfully on earlier versions of Xcode.
I referred the Link but not getting any satisfied answer, please help me out this,
Thanx in advance. :)
The block of code is:
_mainSectionsController = [[[MainSectionsController alloc] initWithNibName:nil bundle:nil] autorelease];
[self addChildViewController:_mainSectionsController];
**Init method of _mainSectionsController** .
-(id)initWithNibName:(NSString*)nibNameOrNil bundle:(NSBundle*)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (!self) return nil;
self.edgesForExtendedLayout = UIRectEdgeAll;
self.viewControllers = #
[
[[[NavigationViewController alloc] initWithNibName:nil bundle:nil]
autorelease]
];
return self;
}
**init method of NavigationViewController**

Since you have autorelease in your MainSectionsController code I assume that you don't use ARC there. I highly recommend upgrading the code of MainSectionsController and NavigationViewController to ARC. This prevents accidental overreleases that might cause issues like this one.
In addition I'd recommend to move self.viewControllers assignment from the constructor to viewDidLoad if possible.

Call to UIWebView crashing my app in iOS

I have a WebView in my storyboard. I created an outlet property to that webview in my view controller file. Then in my code in I'm calling it like this:
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"news1" ofType:#"html" inDirectory:#"/HTML"]];
[self.webView loadRequest:[NSURLRequest requestWithURL:url]];
}
The problem is my app is crashing when I run this and I don't really know why. I get this error, but I need help deciphering what the issue is.

The HTML file isn't in your bundle or isn't at the path specified. Check the case of the file and folder name. If you build/run in the simulator, you can look through the bundle inside of ~/Library/Application Support/iPhone Simulator/7.1/Applications.
Don't use loadRequest if you want to load html locally. use this

NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];

How to add an SKNode to an SKScene

When I enter this line in initWithSize:Size
[self addChild:world];
I retrive an error Thread 1:signal SIGABRT
world is an SKNode
The children that should be in world are also SKNode's
What am I doing wrong here as when I add the SKNode to the scene I retrieve an error
initWithSize:Size Method:
-(id)initWithSize:(CGSize)size{
if (self = [super initWithSize:size]){
//self.size = CGSizeMake(2048, 1048);
self.backgroundColor = [SKColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0];
_character = [self createCharacter];
[self addChild:_character];
[self addChild:world];
[self createChunks];
[world addChild:_character];
NSLog(#"Children in world: %#",[world children]);
}
return self;
}
createChunks: Method:
-(void)createChunks{
ProceduralMapGeneration *procedure = [[ProceduralMapGeneration alloc]init];
[procedure allocArrays];
_chunkOne = [procedure createChunk];
_chunkOne.position = CGPointMake(self.scene.size.width/2, self.scene.size.height/2);
[world addChild:_chunkOne];
_chunkTwo = [procedure createChunk];
_chunkTwo.position = CGPointMake(400,200);
[world addChild:_chunkTwo];
}
create chunks adds the chunks to world
world is created here
#implementation MainGame{
SKNode *world;
SKSpriteNode *_character;
SKNode *_chunkOne;
SKNode *_chunkTwo;
ProceduralMapGeneration *categoryBitManager;
}

Crashing with custom navigation controller

I ran into an issue when testing my application in iOS7. The application currently runs just fine in iOS5 and iOS6. Based on the stack trace, it would appear that a private method is causing the issue.

This crash happens only when testing in iOS7. It happens as soon as [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil] is called. I cannot find any information about _confirmBarAccessMethods. I assume it is a private UINavigationController method.
Here is the header file for the CustomUINavigationController class:
#import <UIKit/UIKit.h>
#import "CustomUINavigationBar.h"
#interface CustomUINavigationController : UINavigationController
{
CustomUINavigationBar *customNavigationBar;
}
#property (nonatomic, retain) UIColor *titleColor;
#end
This is the init method in which the application crashes:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; // This line causes the application to crash
if (self) {
customNavigationBar = [[CustomUINavigationBar alloc] init];
[customNavigationBar setTintColor:[UIColor colorWithWhite:0.0 alpha:1.0]];
[customNavigationBar setItems:[NSArray array] animated:NO];
[customNavigationBar setDelegate:self];
self.titleColor = [UIColor colorWithWhite:1.0 alpha:1.0];
}
return self;
}
Here is the header file for CustomNavigationBar:
#import <UIKit/UIKit.h>
#interface CustomUINavigationBar : UINavigationBar
{
UIImage *background;
}
#end
Any help would be greatly appreciated. I can provide more information if necessary.
EDIT: Added trace from suggested solution of using custom navigation bar initializer

Create the navigation controller with initWithNavigationBarClass:toolbarClass: and supply your custom navigation bar class. Then perform any configuration you require on the instance created for you by the nav controller superclass.
I finally resolved the issue. CustomerUINavigationController had an override method for the navigationBar accessor. It was attempting to return a nil value. I removed this and the application compiled and ran with no issues.

UILabel [__NSCFString set]: unrecognized selector sent to instance crash

I am having a weird crash related to a UILabel but the crash reporting service I am using doesn't give me much help to locate it. I can't know which Controller and which UILabel is causing it. The only help I have is the following:

Is there anything I can find my way through this? Thanx in advance!
Even though it's an old question, for anyone that encounters a similar issue:
If you're using attributedText in your UILabel, check the attribute value types you're setting. For example:
NSString* s = #"str";
NSMutableAttributedString* as = [[NSMutableAttributedString alloc] initWithString:s];
[as addAttribute:NSForegroundColorAttributeName value:someObjectThatsNotAUIColor range:NSMakeRange(0, s.length)];
will cause the UILabel [__NSCFString set]: unrecognized selector sent to instance crash.
You could try to put this in a .h :
#interface NSString (extended)
- (void)set;
#end
And this in a .m :
#implementation NSString (extended)
- (void)set
{
NSLog(#"[NSString set] ??? impossible !!!");
}
#end
Then set a breakpoint on this method.
Search your project for " set]" then you'll probably already find it, as this is a very untypical method name. If that doesn't help, use NSLog to print out all your labels adresses to your console to find out which label is causing this. Like
for (UIView *sub in self.subviews)
if ([sub kindOfClass:[UILabel class]]) NSLog(#"%p", sub);
(code untested, correct spelling if necessary)
