I'm getting a EXC_BAD_ACCESS on NSUserDefaults :
NSUserDefaults *pref = [NSUserDefaults standardUserDefaults];
[pref setObject:oldLogin forKey:#"login"];
[pref setObject:oldMotdepasse forKey:#"pass"];
[pref setObject:#"OK" forKey:#"opening"];
Where oldLogin and oldMotdepasse are UITextField.
I didn't get this error before, it's very strange. The error appears on the first setObject.
Thanks to read me!
EDIT : now I've got another error argh :
-[NSCFString text]: unrecognized selector sent to instance 0x4b3b2d0

Okay, I used oldLogin as a UITextfield. I just change its type to NSString and delete the .text...
You can't just put a UITextField into NSUserDefaults that won't work. You have to get the string value from the UITextField and put that into NSUserDefaults. [prefs setObject:oldLogion.text forKey:#"login"]
Are you trying to store the text in the text fields? If so then it should be
NSUserDefaults *pref = [NSUserDefaults standardUserDefaults];
[pref setObject:oldLogin.text forKey:#"login"];
[pref setObject:oldMotdepasse.text forKey:#"pass"];
[pref setObject:#"OK" forKey:#"opening"];
from NSUserDefault documentation.
The NSUserDefaults class provides convenience methods for accessing
common types such as floats, doubles, integers, Booleans, and URLs. A
default object must be a property list, that is, an instance of (or
for collections a combination of instances of): NSData, NSString,
NSNumber, NSDate, NSArray, or NSDictionary. If you want to store any
other type of object, you should typically archive it to create an
instance of NSData.
you are trying to store the UITextField.. which is wrong .. So would suggest you to insert the text values of UITextField instead storing the whole object.
There are Two things need to fix in this
for text Field write oldMotdepasse.text and oldLogin.text
At the end also synchnorize it [pref synchronize]
E.g:
NSUserDefaults *pref = [NSUserDefaults standardUserDefaults];
[pref setObject:oldLogin.text forKey:#"login"];
[pref setObject:oldMotdepasse.text forKey:#"pass"];
[pref setObject:#"OK" forKey:#"opening"];
[pref synchronize];

I know that documentation says that it is, and i know that this subject was already under discussion but I have an interesting stack result and I cant conclude anything else but that [NSUserDefaults standardUserDefaults] is not threadsafe. So I will post my crash log and hope that somebody sees something that I can't...

I have this crash in couple of other cases, it always includes some writing to user defaults in one thread and synchronizeing in other thread that crashes.. If anyone has some other explanation I would be very greatfull...
The NSUserDefaults class is thread-safe.

nsuserdefaults in not thread safe . Please check apple documentation if it not discuss about thread safe for any ios terms then it is not thread safe....
My iPhone game crashed whilst on the device and I am attempting to understand what happened.
Every time a user exits the game screen it will send a message to the HomePageController (my top level controller) telling it to save the user data. This works fine all the time except for in this particular instance. The exception thrown seems to state that HomePageController did not recognize the saveUserData selector but I can't see how that can happen as that function is definitely in that controller and it works the rest of the time.
Can anyone offer any advice?

}
[dict writeToFile:[documentsPath stringByAppendingPathComponent:#"userdata.dat"] atomically:YES];
}

}
If currentPuzzle doesn't recognize the selector getPuzzleUserData then the problem is one of these two:
LevelData does not define a method getPuzzleUserData.
currentPuzzle is not an instance of LevelData
So check if the method is actually defined in the class LevelData and not in HomePageController and that when you add items to _puzzles10x10 they are actually instances of LevelData.
To debug further, split your code into as many lines as possible (one instruction per line), add a lot of NSLog calls and see what happens:
NSLog(#"_puzzles10x10: %#", _puzzles10x10);
for (int i = 0; i < _puzzles10x10.count; i++){
LevelData *currentPuzzle = [_puzzles10x10 objectAtIndex:i];
NSLog(#"currentPuzzle#%d: %#", i, currentPuzzle);
UserData *userData = [currentPuzzle getPuzzleUserData]; // change UserData to the correct t class
NSLog(#"userData#%d: %#", i, userData);
NSString *key = currentPuzzle.title;
NSLog(#"key#%d: %#", i, key);
[dict setObject:userData forKey:key];
}
From log it is clear that, you are invoking a method in the object which was not really exist.
(2 CoreFoundation 0x3756da9b -[NSObject doesNotRecognizeSelector:] + 175)
I think the data type of '_puzzles10x10' is changed to some other type by making mistakes in code.
Before I begin, I should tell you that this only happens in iOS 5.1. Before the most recent update, this had never happened and it still does not happen on any other version. That said, here's what's going on.
When a user logs out of my app, one of the things that happens is that all of the NSUserDefaults get deleted. Rather than manually removing every key I might add to the user's defaults, I just completely delete all of the NSUserDefaults, using the method suggested in this SO question:
NSString *appDomain = [[NSBundle mainBundle] bundleIdentifier];
[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:appDomain];
What seems to happen though, is that every time I try to create a UIWebView after having removed NSUserDefaults, I get an EXC_CRASH (SIGABRT). The crash happens when I call [[UIWebView alloc] initWithFrame:frame]. Strange right? Completely quitting and reopening the app allows UIWebViews to be created again.
So, I managed to figure out that removing the defaults would cause the UIWebView issue, but to be sure, I added a symbolic breakpoint for -[NSUserDefaults setObject:forKey:].
Creating a UIWebView does indeed trigger the breakpoint.
Poking through the crash logs gives me the exception reason:
-[__NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: WebKitLocalStorageDatabasePathPreferenceKey)
And here's the beginning of the stack trace:

What I'm doing for now, and what works, is just keeping track of the NSUserDefaults keys I have set and removing them all manually when I need to. But there's always a risk I might forget a sensitive key, so simply clearing all NSUserDefaults strikes me as more sensible. So, I would like to know why I can't do that. Is it a bug or am I doing something wrong?
If you want any more info, just let me know! Thanks.
EDIT: Doing [[NSUserDefaults standardUserDefaults] synchronize] after deleting all NSUserDefaults does not help.
I'm seeing this issue as well, I think you have to have created a UIWebView first before clearing user defaults for it to occur. A clean project with the following will cause the crash in iOS5.1, this works fine in iOS5.0 and earlier:
UIWebView *webView = [[UIWebView alloc] init];
[webView release];
[[NSUserDefaults standardUserDefaults] setPersistentDomain:[NSDictionary dictionary] forName:[[NSBundle mainBundle] bundleIdentifier]];
UIWebView *anotherWebView = [[UIWebView alloc] init];
[anotherWebView release];
I can work around the crash by doing this instead, which avoids having to remember all your settings keys:
id workaround51Crash = [[NSUserDefaults standardUserDefaults] objectForKey:#"WebKitLocalStorageDatabasePathPreferenceKey"];
NSDictionary *emptySettings = (workaround51Crash != nil)
? [NSDictionary dictionaryWithObject:workaround51Crash forKey:#"WebKitLocalStorageDatabasePathPreferenceKey"]
: [NSDictionary dictionary];
[[NSUserDefaults standardUserDefaults] setPersistentDomain:emptySettings forName:[[NSBundle mainBundle] bundleIdentifier]];
Anyone see any issues with doing it this way?
It sounds like you're removing some sort of private preference, which is probably a new bug, either with NSUserDefaults (you shouldnt be able to remove it) or UIWebView (it should cope with a missing entry).
Have you tried the method from the other answer (setting a blank dictionary?). Does that give the same results?
How about if you get the dictionary representation of NSUserDefaults, get all the keys, and iterate through those, removing the objects? (let me know if you need a code sample for that).
It works for me
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSDictionary *userDefaultsDictionary = [userDefaults dictionaryRepresentation];
NSString *strWebDatabaseDirectory = [userDefaultsDictionary objectForKey:#"WebDatabaseDirectory"];
NSString *strWebKitLocalStorageDatabasePathPreferenceKey = [userDefaultsDictionary objectForKey:#"WebKitLocalStorageDatabasePathPreferenceKey"];
[userDefaults removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];
if (strWebDatabaseDirectory) {
[userDefaults setObject:strWebDatabaseDirectory forKey:#"WebDatabaseDirectory"];}
if (strWebKitLocalStorageDatabasePathPreferenceKey) {
[userDefaults setObject:strWebKitLocalStorageDatabasePathPreferenceKey forKey:#"WebKitLocalStorageDatabasePathPreferenceKey"];}
[userDefaults synchronize];
Simpler it will be to use the code below:
[self saveValue:#"" forKey:#"WebKitLocalStorageDatabasePathPreferenceKey"];
[[NSUserDefaults standardUserDefaults] synchronize];
It is easier.
My code is as follows:
NSMutableDictionary *configure = [[NSUserDefaults standardUserDefaults] objectForKey:#"configure"];
if (!configure){
configure = [NSMutableDictionary dictionary];
[configure setValue:[NSMutableDictionary dictionary] forKeyPath:#"select"] ;
[configure setValue:[NSMutableDictionary dictionary] forKeyPath:#"select.around"];
[configure setValue: #"All" forKeyPath:#"select.around.name"];
[[NSUserDefaults standardUserDefaults] setObject:configure forKey:#"configure"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
NSString *keyPath = #"configure.select.around";
NSMutableDictionary *aroundConfigure = [[[NSUserDefaults standardUserDefaults] valueForKeyPath:keyPath] mutableCopy];
[aroundConfigure setObject:#"" forKey:#"name"];
[[NSUserDefaults standardUserDefaults] setValue:aroundConfigure forKeyPath:keyPath];
It's crashing every time with the error below:

I know that setObject:forKey: should used with a mutable dictonary . Is there any problem using KVO with NSUserDefaults? By the way, the platform I use is iPhone.
Your code isn't doing what you think it is doing:
NSMutableDictionary *configure = [[NSUserDefaults standardUserDefaults] objectForKey:#"configure"];
This sets configure to be the value of your standard defaults to the value of the key configure
configure = [NSMutableDictionary dictionary];
This sets configure to a new, empty dictionary, not the one you got from User defaults
[configure setValue:[NSMutableDictionary dictionary] forKeyPath:#"select"] ;
You now put an empty dictionary as the value for the key select
[configure setValue:[NSMutableDictionary dictionary] forKeyPath:#"select.around"];
You are adding another empty dictionary for this key path
[configure setValue: #"All" forKeyPath:#"select.around.name"];
And you are setting a string value for this key path
[[NSUserDefaults standardUserDefaults] setObject:configure forKey:#"configure"];
You are now putting this odd dictionary into NSUserDefaults
[[NSUserDefaults standardUserDefaults] synchronize];
NSString *keyPath = #"configure.select.around";
NSMutableDictionary *aroundConfigure = [[[NSUserDefaults standardUserDefaults] valueForKeyPath:keyPath] mutableCopy];
This is just an empty mutable dictionary
[aroundConfigure setObject:#"" forKey:#"name"];
You are setting an empty string for some key in this dictionary
[[NSUserDefaults standardUserDefaults] setValue:aroundConfigure forKeyPath:keyPath];
And then you set this odd dictionary into the the user defaults.
Which is all very confusing.
What is it that you are trying to do?
Edited to add
There's no point providing code if you've "simplified" it we can't see what it's supposed to do.
Your app is crashing because you are trying to change a key value pair of a NSDictionary which is immutable instead of a NSMutableDictionary. See line 6 of your trace.
Since you've provided "simplified" code - I don't know where you are doing this.
Today i also faced this problem because i am making data in dictionary like this
NSMutableDictionary *Dic =[myMutableAry objectAtIndex:0];
after getting data when i am updating my dic value then getting crash
* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[__NSCFDictionary
setObject:forKey:]: mutating method sent to immutable object'
Then i did got solution after a lot of research , so just do one thing
NSMutableDictionary *Dic = [NSMutableDictionary dictionaryWithDictionary:[myMutableAry objectAtIndex:0]];
The way you have used the NSUserDefaults is wrong, NSUserDefaults return a non mutable dictionary. That is the cause of this issue. Therefore, you have to request a mutable object explicitly from NSUserDefaults. Please use the code line below.
NSMutableDictionary *configure = [[[NSUserDefaults standardUserDefaults] objectForKey:#"configure"]mutableCopy];
This work with me.
Thanks Good luck :)
I created this awesome iPad game - clean and fun to play, and people that manage to play it more than once love it.
In some cases, however, it will not launch for the second time.
I can't debug it since it works perfect on my iPad, simulator and on all my friend's iPads.
One customer told me that it works on 32GB but not on 64GB iPads - could this be it?
Any help would be appreciated - this is sinking my ratings (and for a good reason, unfortunately)
Would love to give out promo code to anyone willing to look into this.
Thanks!!

You need to find the line of code that frame 13 of your stack trace represents.
I would hope that you used the "Build and Archive" feature of the recent versions of Xcode. In this case, all you would need to do is drag and drop the crash log to the Xcode Organizer. This will "symbolicate" the crash log, meaning that it will convert the addresses to classes and methods.
Once you know the line that caused the error it will (hopefully) be relatively simple to figure out what went wrong. My guess would be memory corruption of some description -- a value you assumed you saved on the first run isn't there or something.
I think some object or UI element of yours is getting released (deallocated), but you expect it to still exist:

I dont know the specifics of the iPad and obj-c development.
However, this looks like memory corruption and/or dangling pointers in some way.
For example, you could be modifying an array beyond its bounds. Double check all your loops and add debug asserts that verify the bounds.
Another possibility is that you could be using pointers to objects that have been deleted, and writing/interpreting this memory has undefined effects. Usually it just crashes.
Or you could have uninitialized pointers.
All of this falls into the category that I like to call The Insanity of Developing Applications in C/C++/etc. Unchecked buffer bounds, manual memory deallocation, and unguarded call stack memory are just nutty ideas w/r to modern application development.
