I am Trying to put UISegmentedControl on theNavigation Item but it crash my xcode .. I simply added the UISegmentedControl in the Interface Builder file(IB) file and then in viewDisAppear
.h
IBOutlet UISegmentedControl *segmentedControl;
.m
self.navigationItem.titleView=segmentedControl;
this simply crash my xcode with the error

My problem it's when instance a SecondViewController in FirstViewController for assign a value on variable ID, the problem is I can not use Segue and NaviagtioController..
Maybe a solution use a Static variable?, How do it, or tell me a tip?
I do it this code:
// In the class FirstViewController.m
#import "SecondViewController"
NSString *identifier = [NSString stringWithFormat:#"%#", [self.cat objectAtIndex:indexPath.row]];
// Start the code causes an error
ViewControllerOne *instance = [[ViewControllerOne alloc]init];
instance.ID = [[NSString alloc] initWithFormat:#"%#",identifier];
// End code causes error
// In the SecondViewController.h
#property (nonatomic, retain) NSString *ID;
// In the SecondViewController.m
#synthesize ID;

Try this
[[NSUserDefaults standardUserDefaults]setValue:yourVal forKey:#"myValue"];
NSString *myVal = [[NSUserDefaults standardUserDefaults]valueForKey:#"myValue"];
Hope i helped
Cause of error is very clear from the log Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'UICollectionView must be initialized with a non-nil layout parameter'
Your ViewControllerOne is a UICollectionViewController sub class. It should be initialize with a non nil layout parameter.
UICollectionViewLayout *layout= [UICollectionViewFlowLayout new];
ViewControllerOne *instance = [[ViewControllerOne alloc]initWithCollectionViewLayout:layout];
However passing data between view controller remains there.
I'm setting image to a UIImageView using in the below code
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
for(int i=0;i<[radioButtons count];i++){
[[radioButtons objectAtIndex:i] setImage:[UIImage imageNamed:#"checkbox_unchecked.png"]];
}
UIImageView *imageViews=(UIImageView *)[self.view viewWithTag:indexPath.row];
[imageViews setImage:[UIImage imageNamed:#"checkbox_checked.png"]];
}
So on clicking any tableview cell the images gets sets. But once if I click on objectatindex:0
then the app crashes. I'm unable to fix this.
Below is the crash log:

I think you are not getting UIImageView Object,you are getting uiview types object that's why it crashes. you should try to Define another tag property like 999+indexPath.row. Got it somewhere you define the tag=0 or IB automatically takes tag=0 to all object so it taking uiview with tag 0 not uiimageView
this means that you are sending message -(void)setImage to UIView, not to UIImageView. Make sure that view with tag indexPath.row and all radioButtons in array are actually UIImageView
(I am developing an app that presents chat messages in a table. But, this chat can't be started by the user, when the user receives a message the chat view opens. So, I made this code:
- (void) newMessageReceived:(NSMutableDictionary *)message
{
General *general = [General sharedManager];
NSString *firstmessage=[message objectForKey:#"msg"];
NSString *from=[message objectForKey:#"sender"];
NSArray *listItems = [from componentsSeparatedByString:#"#"];
NSString *fromsplit=[listItems objectAtIndex:0];
general.firstmess=firstmessage;
general.firstfrom=fromsplit;
NSLog(#"Mensaje recibido: %# de %#", [message objectForKey:#"msg"], fromsplit);
ChatViewController *cvc=[[ChatViewController alloc]initWithNibName:#"Chat" bundle:nil];
[[self navigationController]pushViewController:cvc animated:YES];
}
Everything is ok, until here. The ChatViewController extends UITableViewController. But, when a message is received i get the following exception:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "Chat" nib but didn't get a UITableView.
Then, i try to change the class extended to UIViewController (did this to check that the program enters the numberOfRowsInSection method) and then i receive:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ChatViewController setTableViewStyle:]: unrecognized selector sent to instance 0x9863200'
I think that solving the first exception would fix my problem. Any help?
Thank you.
In the second exception i think you have called [self setTableViewStyle:] method, while
you have made it UIViewController.
So try to call this method by tableViewOutlet.
[tableView setTableViewStyle:];
Hope this will help you
Solved it. i click the .xib file, under "objects", clicked "View". And then, in the Identity Inspector (the third one, starting from the left), in Custom Class, set it to UITableView. It was simply "View" before. And then, everything worked fine.
I have an NSObject set up to control various elements on my screen.
I initialize the class inside my View Controller like this:
self.pageSetupClass = [[PageSetup alloc] set:self.pageID];
In IB I have added my NSObject object and linked a button to an IBOutlet on it. I've also linked it to an IBAction found in the object. When I click this button the app crashes and I get this error:

terminate called after throwing an instance of 'NSException'
There is nothing in the function at the moment so it must be the calling that crashes it...right?
If you need me to post more code I certainly can. If you have any ideas I'm all ears. Thank You
Edit:
This is the contents of the function set called out when I initialize the PageSetup object:
-(PageSetup*) set:(int) i {
self = [super init];
if(self) {
self.iD=i;
self.pageSetupFile = [[NSBundle mainBundle] pathForResource:#"PageSetup" ofType:#"plist"];
self.pageSetupArray = [[NSMutableArray alloc] initWithContentsOfFile:self.pageSetupFile];
self.pageInfo = [self.pageSetupArray objectAtIndex:self.iD];
[self initializeSoundBytes];
[self initializeAnimations];
[self initializeToys];
NSLog(#"Page Setup Initializing: %#", self.pageInfo);
return self;
}
return self;
}
Another Edit:
I set my set function to return (void) and no longer initialize it using init.
I now receive this error message:

terminate called after throwing an instance of 'NSException'
Final Edit:
I had forgotten to connect my NSObject to the File's Owner in IB.
Could it be that when I reinitialize
this object...
Wait... what? In Objective-C you never call init* methods more than once.
In any case, the underlying problem appears to be a straightforward memory management issue. Something is being released before its time and it just so happens that a dictionary lands at that location. Turn on zombie detection and it'll likely catch the problem.
self.pageSetupClass = [[PageSetup alloc] set:self.pageID];
What does set: return? Is that a method of your PageSetup class? Does it return self?
Because apparently you're assigning pageSetupClass to whatever set: returns...
Unless set: returns self, you should try this:
self.pageSetupClass = [[PageSetup alloc] init];
[self.pageSetupClass set:self.pageID];
Edit:
ok, if you added the object in IB, the object was already instantiated for you when you loaded the nib, and the IBAction and IBOutlet connections have already been made.
When you do self.pageSetupClass = ..., you're setting pageSetupClass to a new instance, and that probably leaves the button with a bad target for its IBAction.
If the object was instantiated from the nib, and you have a reference to it in pageSetupClass from a IBOutlet, then just set whatever you want in the object, no need to alloc a new one.
I'm creating an iPad app, and I have two classes: NWRootViewController : UITableViewController and UINewFeedViewController : UIViewController. In NWRootViewController I have an UIBarButtonItem, which, when tapped, pops up a modal view controller called NWNewFeedViewController:
// THIS CODE IS IN NWROOTVIEWCONTROLLER.M
// New Feed
-(IBAction)showNewFeedViewAction:(id)sender {
[newFeedViewController setModalPresentationStyle:UIModalPresentationFormSheet];
[self presentModalViewController:newFeedViewController animated:YES];
}
This works fine. However, in the NWNewFeedViewController's view, I have another UIBarButtonItem which does this when tapped:
// THIS CODE IS IN NWNEWFEEDCONTROLLER.M
// Buttons
-(IBAction)cancelAction:(id)sender {
[self dismissModalViewControllerAnimated:YES];
}
When I tap this button, the app crashes with:

Can anyone help me? Thanks
Your cancel button has a target of your detail controller; you meant to target your new feed controller. So check how you configured the cancel button.
Your app is trying to call an object that has already been released. Enable zombie objects as explained here to find out what object is trying to be accessed.
