the following code:
-(void)sendSMS
{
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
if ([MFMessageComposeViewController canSendText])
{
self.msgController = [[MFMessageComposeViewController alloc]init];
self.msgController.messageComposeDelegate = self;
self.msgController.body = [standardUserDefaults objectForKey:#"geoAlarmDistressFlareMsgText"];
self.msgController.recipients = [standardUserDefaults objectForKey:#"geoAlarmDistressFlareTelNumbers"];
[self presentModalViewController:self.msgController animated:YES];
}
}
...causes the app to crash when run on my iphone at the [[MFMessageComposeViewController alloc]init]; line with the following error:
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString count]: unrecognized selector sent to instance
I don't understand why - the msgController is declared (and synthesized) as a MFMessageComposeViewController, and i have declared the delegate and delegate method. Any ideas? No other questions on here seem to be asking the same question...

NSKeyedArchiver returns object that you have stored in it. eg. if you have stored an array then it will return an array. so be careful while unarchiveing objects.
in following example i have read an array from NSKeyedUnarchiver.
NSData *data = [[NSMutableData alloc] initWithContentsOfFile:filePath];
NSArray *arr = [NSKeyedUnarchiver unarchiveObjectWithData:data];
Look in the crash log's stack trace to see where exactly this call is
happening.
If the variable you're sending -row to isn't actually typed as an
NSArray, it's likely that you've failed to follow the memory
management rules for that variable. These same symptoms are very
commonly caused by that. Something that responds to -row could have
existed at one point, been deallocated because you didn't -retain it,
and then an NSArray was later allocated in that spot.
Run a "Build & Analyze," and re-re-review the memory management
guidelines until you know them in your sleep.

I'm trying to implement in iPhone in app purchase in my app.
I have an IBAction on a button to buy a mini-game :
-(IBAction) buyGame:(id)sender {
SKProduct *product = [[InAppGameIAHelper sharedHelper].products objectAtIndex:0];
NSLog(#"Buying %#...", product.productIdentifier);
[[InAppGameIAHelper sharedHelper] buyProductIdentifier:product.productIdentifier];
self.hud = [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
_hud.labelText = #"Buying...";
[self performSelector:#selector(timeout:) withObject:nil afterDelay:60*5];
}
[InAppGameIAHelper sharedHelper] allows to load the items from the store, and to load the list of product.
[InAppGameIAHelper sharedHelper].products is a NSArray :
products (
"com.me.myapp"
)
There when I am tapping the buy button my app getting crashed and getting the following error :
2013-03-04 20:24:50.314 isam[11922:c07] -[__NSCFConstantString productIdentifier]: unrecognized selector sent to instance 0x22ae30
2013-03-04 20:24:50.318 isam[11922:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString productIdentifier]: unrecognized selector sent to instance 0x22ae30'
is the
SKProduct *product = [[InAppGameIAHelper sharedHelper].products objectAtIndex:0]; line actually returning you a SKProduct?
My guess is your code is crashing before it can print the NSLog because your method is returning somehow an NSString.
I have a method that sets up NSXMLParser with the correct data that I am pretty sure is causing a memory leak.
This is my first time using instriments to try and solve a memory leak and have got it down to the offending method..
by looking at the response caller value in instruments memory leak testing.
I am hoping you can tell me where the memory leak is here... because I release both myDataArray and parser... im just not sure where I am going wrong.. do I need to assign them nil also?
- (void)startTheParsingProcess:(NSData *)parserData
{
[myDataArray release]; // clears array for next time it is used.
myDataArray = [[NSMutableArray alloc] init];
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:parserData]; //parserData passed to NSXMLParser delegate which starts the parsing process
[parser setDelegate:self];
[parser parse]; // starts the event-driven parsing operation.
[parser release];
}
any help would be appreciated.
UPDATE:
I have made the changes to my application and when I run it on the simulator I do not get any memory leak errors..
however if I run it on my phone get this in the console...

I'm trying to get the fireDate from an already set notification
Heres my code:
NSArray *notificationArray = [[NSArray alloc] initWithObjects:[[UIApplication sharedApplication] scheduledLocalNotifications], nil];
if ([notificationArray count] > 0) {
NSDate *now = [NSDate date];
UILocalNotification *locNotification = [[UILocalNotification alloc] init];
locNotification = [notificationArray objectAtIndex:0];
NSDate *otherDate = locNotification.fireDate;
}
The locNotification has the values but the last line when I try to instantiate otherDate I'm getting
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM fireDate]: unrecognized selector sent to instance 0x1e4e20'
* Call stack at first throw:
I really don't know what I'm doing wrong.
Thanks in advance
You're using the wrong init method. Instead of NSArray's -initWithObjects:, you want:
NSArray *notificationArray = [[ NSArray alloc ] initWithArray:
[[ UIApplication sharedApplication ]
scheduledLocalNotifications ]];
You get the exception because notificationArray only contains one object, the array returned by -scheduledLocalNotifications.
it seems my Problem isn't a problem for anybody eles because I havend fount anything about it.
so it maybe isn't such a big Problem but for me it is.
I have this MutableArray filled with alot of data from an XML file.
-Name -Age -Address
The search goes for the Name, and the filtering works pretty fine so far.
what I do is search the array with rangeOfString but that only returns the String (-Name) and not the Array with it's content like the original Array because its only a string now.
can anyone tell me how do I accomplish this
That's my search so far
if ([[self searcher] length] != 0)
{
for (NSString *currentString in [self listOfContent])
{
if ([currentString rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location != NSNotFound)
{
[[self filteredListOfContent] addObject:currentString];
}
searcher is the String in the SearchBar.
or is there any other more efficent way or is it possible to search for any value in the MutipleArry?!?
Any Ideas and suggestions are welcome
I changed the code to this
NSString *searchText = searchBar.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
for (NSDictionary *dictionary in listOfContent)
{
//NSArray *array = [dictionary objectForKey:LNAME];
[searchArray addObject:dictionary];
}
for (NSString *sTemp in searchArray)
{
NSLog(#"array %#", searchArray);
if ([sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch].location != NSNotFound)
[filteredListOfContent addObject:searchArray];
}
the log shows that the filter seems to work but then I get this error

can anyone tell me what the problem is
And Still no solution found I changed the Code to this:
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
for (NSDictionary *dictionary in contentsList)
{
NSArray *array = [dictionary allValues];
[searchArray addObjectsFromArray:array];
}
for (NSDictionary *dict in searchArray)
{
if ([[dict valueForKey:#"NAME"] rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location != NSNotFound) {
NSLog(#"Filter %#", dict);
[searchResults addObject:dict];
}
now i Have the array with the values but still get the error

That error means you treated an NSString as if it were an NSDictionary by sending the message -objectForKey: to it.
