I'm programming an application in Swift and Objective-C and when I run the test app on the iPhone everything works, but when i was trying to start a call the application crashed showing this:
*** First throw call stack:
(0x181be11b8 0x18061855c 0x181be1100 0x182610eb8 0x100265a2c 0x187acbd30 0x187acbcb0 0x187ab6128 0x187acb59c 0x187acb0c4 0x187ac6328 0x187a96da0 0x18828075c 0x18827a130 0x181b8eb5c 0x181b8e4a4 0x181b8c0a4 0x181aba2b8 0x18356e198 0x187b017fc 0x187afc534 0x1002bc898 0x180a9d5b8)
libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb) terminating
This is the button code:
- (IBAction)startCallButton:(id)sender {
TCallViewController *callViewController = [[TCallViewController alloc] init];
[self.navigationController pushViewController:callViewController animated:YES];
NSString *handle = [[NSString alloc] initWithString:_handle];
BOOL Video = _video;
if ((handle = callViewController.handle) ){
Video = callViewController.video;
[callManager startCallWithHandle:(handle) video:Video];
}
}
how can I solve this problem?

I am getting the following exception, which is terminating the app.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0x7abe4f90'
Following is the code:
- (NSMutableData*)dataForConnection:(URLConnection*)connection {
NSMutableData *data = [receivedData objectForKey:connection.tagKey]; // Exception Here
return data;
}
Could anyone please suggest how to fix it? Thank you in advance!
Problem is due to not allocating receivedData properly, since you have declared it as instance variable, so you should make it using the property declaration like this:
#property(nonatomic, strong) NSMutableDictionary *receivedData;
This will ensure that receivedData does not get released and reference this using self.receivedData in your code.
Maybe this is helpful
[__NSArrayM objectForKey:]
NSArray have not method called objectForKey:
Your object receivedData is NSArray class , change to NSDictionary.
I'm working on an app and it's my first time using Core Data and everything was going smooth until I hit a rock.
Here is my stack trace

and here is the code that caused the problem:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
//Fetch data from persistence
NSManagedObjectContext *managedObjectContext = [self managedObjectContext];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] initWithEntityName:#"Entity1"];
NSFetchRequest *fetchRequest2 = [[NSFetchRequest alloc] initWithEntityName:#"Entity2"];
self.arr1 = [[managedObjectContext executeFetchRequest:fetchRequest error:nil]mutableCopy];
self.arr2 = [[managedObjectContext executeFetchRequest:fetchRequest2 error:nil]mutableCopy];
[self.tableView reloadData];
}
I really don't get what's wrong.
Thanks in advance
Usually, this error is about the entity name you're using is not kind of NSString, so the code believes that you are using some type else (not NSString).
But it could be also, that is the model associated with the context’s persistent store coordinator does not contain an entity named Entity1.
I have two targets in my workspace an iOS App (Bundle id: com.gotit.iphone.gotit, App Group: group.com.gotit.iphone.gotit) and an share extension (Bundle id: group.com.gotit.iphone.gotit.Got-it, App Group: group.com.gotit.iphone.gotit).
I can use my share extension without problem but sometimes (not all the time) when I directly come back to my iOS app I have this error and my app crashes :

I use AFNetworking (with BDBOAuth1SessionManager) and this is how I create my networkManager :
+ (instancetype)create {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_sharedClient = [[[self class] alloc] init];
});
return _sharedClient;
}
+ (instancetype)sharedClient {
if (!_sharedClient) {
[GotItClient create];
}
return _sharedClient;
}
- (id)init {
self = [super init];
if (self) {
NSURL *baseURL = [NSURL URLWithString:kSCGotItClientAPIURL];
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:#"group.com.gotit.iphone.gotit"];
sessionConfiguration.sharedContainerIdentifier = #"group.com.gotit.iphone.gotit";
_networkManager = [[BDBOAuth1SessionManager alloc]
initWithBaseURL:baseURL
sessionConfiguration:sessionConfiguration
consumerKey:kSCGotItClientKey
consumerSecret:kSCGotItClientSecret
shareDefaultGroupId:#"group.com.gotit.iphone.gotit"];
_networkManager.responseSerializer = [[AFJSONResponseSerializer alloc] init];
//4 operations at same time
[[_networkManager operationQueue] setMaxConcurrentOperationCount:20];
}
return self;
}

I am using BlackRaccoon to download a file from FTP server. Following is the code:
- (IBAction)download:(id)sender {
downloadData = [NSMutableData dataWithCapacity: 1];
downloadFile = [[BRRequestDownload alloc] initWithDelegate: self];
downloadFile.path = #"psnewsletter.pdf";
downloadFile.hostname = #"server";
downloadFile.username = #"user";
downloadFile.password = #"pswd";
[downloadFile start];
}
Its gives following error
2014-02-20 11:48:43.526 BlackHillPrimarySchool[2036:a0b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainViewController requestFailed:]: unrecognized selector sent to instance 0xcd609f0'
Any help will be appreciated.
requestFailed: is one of the BRRequest delegate method that you must implement in your view controller.
- (void)requestFailed:(BRRequest *)request {
BRRequestError *reqError = request.error;
// check the error, handle as needed.
}
I'm not sure how your code even compiled. This is a required method of the protocol.
i've a piece of code that should get the current location and than put lat and long in a string.
when a new location is found i put it in a NSString
currentLatit = [NSString stringWithFormat:#"%f",newLocation.coordinate.latitude];
currentLongit = [NSString stringWithFormat:#"%f",newLocation.coordinate.longitude];
Than when i press a button i do:
NSLog(currentLatit);
[[UIApplication sharedApplication] openURL:[[NSURL alloc] initWithString: [NSString stringWithFormat:#"http://maps.google.com/maps?saddr=%#,%#&daddr=%#,%#",currentLatit,currentLongit,detailLatitudine,detailLongitudine]]];
but when i execute this, i get this error:

terminate called throwing an exception(gdb)
The error occur on the NSLog execution
realy cannot understand what's wrong whit this simple code...
thanks for any help
-UPDATE-
changed the NSLog as follow:
NSLog(#"%#",currentLatit);
Now the app crash with BAD_ACCESS_EXCEPTION on the NSLog
No, it seems the app crashed at some point other than NSLog. Please clean and build. Or Enable NSZombie and get the exact error location.
Update:
Just do like as following and try.
if( currentLatit )
[currentLatit release];
if( currentLongit )
[currentLongit release];
currentLatit = [[NSString stringWithFormat:#"%f",newLocation.coordinate.latitude] retain];
currentLongit = [[NSString stringWithFormat:#"%f",newLocation.coordinate.longitude] retain];
