CALayerInvalidGeometry'CALayerInvalidGeometry' - objective-c

I'm making a tabbed view application and using CloudMade's API.
I have a working project in a single view application which I try to copy to the tabbed view one.
I copied and pasted everything, set up the project preferences and everything.
The tabbed view FirstViewController is exactly the same as the older single view app.
How ever when I run the app, I get this error:
Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer bounds contains NaN: [inf inf; nan nan]'
I tried to google but nothing came up. It's my first tabbed view app so I'm not sure if there are stuff I need to pay attention to.
I'm not even sure what code section or error report to paste here.
Any help would be appreciated!
Thanks alot!

EDIT Hi, As it seems, the tabbed view controller has nothing to do with it.
I copied it again for a new single view application, and it doesn't work again.
I should probably mention (didn't think it made any difference before) that the working app does NOT use storyboard, just a single xib file. the 2 not working (tabbed and single view) DOES
I don't even know where to start..
Thanks

The problem was that I didn't link the map outlet, mapView, to the RMMapView object in the storyboard. Now it is working.

In your -[ParkerAssistantFirstViewController viewDidLoad] method, you send the recalculateGeometry message to an instance of RMPath. RMPath then sets the bounds of a CALayer.
Looking at the exception message, we can see that RMPath is setting the bounds of the layer to the rectangle [inf inf; nan nan]. The word inf is short for “infinity”, so your rectangle's origin is at infinity. The word nan means “not-a-number”, so your rectangle's size is completely invalid. That is what CALayer is complaining about.
Looking at the variables in your first edit, I see that scale is 0. That is suspicious. If that is the zoom factor of the view, then it's probably not valid. If that is something you control, try setting it to 1 (or some other small positive number).

Have you linked the QuartzCore.framework? I'm pretty sure CALayer requires the QuartzCore. You can do this by selecting your Target --> Build Phases Tab -- Link Binary with Libraries. click the plus sign, and scroll down to the bottom and select QuartzCore to link it to your project.

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.

libc++abi.dylib: terminating with uncaught exception of type NSException
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.

UIAlertView crashes in iOS7

We had compiled and deployed an app in iOS 6 environment. But, now the app is getting crash in iOS 7 whenever showing an alert.
App simply getting crash in [alertView show];
But, the same app is running perfect in iOS 6.
Code for showing alert
-(void)displayAlertWithMessage:(NSString *)message withTitle:(NSString *)title andTag:(int)tag
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
and calling like this
[self displayAlertWithMessage:#"Please enter valid username!" withTitle:nil andTag:1];
Here, is the crash log.

Thanks in advance.
As per crash log it says to me "[UIViewController _loadViewFromNibNamed:bundle:]" unable to load nib file.
But, in my project I had created a category for UIViewController class and overridden the -(id)init method. Upto ios6, while showing an alert this category method is not at all executing, but from ios7 onwards overridden init() method of UIViewController.
So, I fixed this issue by adding the another validation in UIViewController category's init() method for checking the class method is UIAlertView or not, if it is UIAlertView then simply calling [super init]; instead of doing my other stuff relating to view controllers.
Sample code:
- (id)init
{
NSString *viewControllerName = [NSString stringWithFormat:#"%#",[self class]];
if([viewControllerName isEqualToString:#"UIAlertView"])
{
self = [super init];
}
else
{
// my stuff
}
return self;
}
you can test it.. try to avoid nil.. instead of that put something... like
[self displayAlertWithMessage:#"Please enter valid username!" withTitle:#"Hello" andTag:1]
and you need to release alert view so in function write release code...

A good way to make this version independent is:
if ([tabBarController.tabBar respondsToSelector:#selector(setTintColor:)]) {
[tabBarController.tabBar setTintColor:color];
}
In IOS 5 this will set the tabbar tintcolor and in lower versions it wont crash
According to the documentation tintColor is only available in iOS 5.0 and later. The clue was that the 4.3 simulator is saying unrecognized selector sent to instance which basically means the method doesn't exist.
You'll need to do one of the following:
Set your minimum required iOS to 5.0.
Only apply the tint when running on iOS 5.0 or greater.
Use an alternative method supported by both versions.
Documentation Excerpt:
tintColor
The tint color to apply to the tab bar background.
#property(nonatomic, retain) UIColor *tintColor Availability
Available in iOS 5.0 and later.
try this
tabB.tintColor=[UIColor colorWithRed:124.0/255.0 green:150.0/255.0 blue:32.0/255.0 alpha:1.0];

terminate called after throwing an instance of 'NSException'
Program received signal: “SIGABRT”.
what am i doing wrong?
thank you
You have probably assigned the "cure" class to a UIView in the "Identity" tab in Interface Builder. "cure" is a view controller, so it doesn't implement any UIView methods (such as -superview), and thus throws an exception when trying to load the nib.
Btw, you have a whole bunch of leaks in your code, please read something about memory management in Objective-C (perhaps also about Cocoa naming conventions).

can someone please explain why this keeps crashing on iOS 4.2?

The code worked in iOS 3.2 and in 4.2 it keeps crashing.
Here's the line that it crashes on.
NSArray* address = [NSArray arrayWithArray:[[[access.filteredResults objectAtIndex:[indexPath row]] addressArray] objectAtIndex:0]];

terminate called after throwing an instance of 'NSException'
At first glance, this line is your problem:
[NSArray initWithArray:range:copyItems:]
at first glance, it might be that you need indexPath.row not [indexPath row].
Because iOS 4.2 is still under NDA, we cannot talk about 4.2-specific code.
We can however, talk about 4.1 and previous.
First, you're going to go to the 4.2 diffs page after you sign into the iOS Dev Center. This will tell you what's changed in that release. Since these pages only show release to release, look at the 3.2-4.0 diffs, 4.0-4.1 and 4.1-4.2 diffs. You are looking for a change in the API for UITableView or NSArray that obviously cannot be talked about here.
Second, you're going to download the WWDC '10 session on crash reports. It's a little tedious but the hour spent learning about how to read a crash report is WELL worth it.
Hope this helps!
The error you're getting tells you that the selector getObjects:range: is being sent to an __NSCFDictionary. So clearly the following:
[[[access.filteredResults objectAtIndex:[indexPath row]] addressArray] objectAtIndex:0]
... used to return an NSArray, but is now returning an NSDictionary.
I don't know what access is so I have no idea what else to say other than you can change the line you cited as the source of the error to:
NSDictionary* address = [NSDictionary dictionaryWithDictionary:[[[access.filteredResults objectAtIndex:[indexPath row]] addressArray] objectAtIndex:0]];
Once you've done that, whatever code follows that uses address clearly needs to also change to deal with the fact that you're no longer accessing an array.
You need the new iOS CookBook code
