My app here is named Movies. I am using Splunk Mint (formerly BugSense) to capture crash reports. I recently updated to their new 4.0 SDK. Here is a crash report today that I don't understand. At what line exactly is the crash happening in my code?
Crash is: NSInvalidArgumentException *** -[NSPlaceholderString initWithString:]: nil argument
You would think line #4? But I have no idea what the heck URLBlackListManager is. Or is it line #0, a crash inside of MKSKProduct (the code I've been using for years to make in-app purchases easy), but then why would it say it's coming from CoreFoundation? Or is it line #10, the last line that Movies actually gets called with my code?
And I have NO clue what SplunkNSURLConnectionSendSynchronousRequestReturningResponseError is and their website doesn't have any info on it.
I have been unable to report the crash, but it's happened at least 10 times on different devices for different people.
I'm a bit confused... anyone have any ideas?

Here's the verifyReceiptOnComplete code by the way from line #0 in the stack trace... let me know if you see any possible way to get a nil NSString crash anywhere here:
- (void) verifyReceiptOnComplete:(void (^)(void)) completionBlock
onError:(void (^)(NSError*)) errorBlock
{
self.onReceiptVerificationSucceeded = completionBlock;
self.onReceiptVerificationFailed = errorBlock;
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#/%#", OWN_SERVER, #"verifyProduct.php"]];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url

[theRequest setHTTPMethod:#"POST"];
[theRequest setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSString *receiptDataString = [self.receipt base64EncodedString];
NSString *postData = [NSString stringWithFormat:#"receiptdata=%#", receiptDataString];
NSString *length = [NSString stringWithFormat:#"%d", [postData length]];
[theRequest setValue:length forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPBody:[postData dataUsingEncoding:NSASCIIStringEncoding]];
self.theConnection = [NSURLConnection connectionWithRequest:theRequest delegate:self];
[self.theConnection start];
}
Just stumbled upon this bug myself and here is what I found:
If you use Cocoapods to install Splunk Mint Express, you get two different Pods:
$> pod search Splunk
-> SplunkMint (4.0.4)
Usage, performance and crash monitoring for your iOS apps
pod 'SplunkMint', '~> 4.0.4'
- Homepage: https://mint.splunk.com/
- Source: download.splunk.com/misc/mint/SplunkMint-iOS.framework.zip
- Versions: 4.0.4, 4.0.3, 4.0.2, 4.0.1 [master repo]
-> SplunkMint-iOS (4.0.21)
Usage, performance and crash monitoring for your iOS apps
pod 'SplunkMint-iOS', '~> 4.0.21'
- Homepage: https://mint.splunk.com/
- Source: download.splunk.com/misc/mint/SplunkMint-iOS.framework.4.0.21.zip
- Versions: 4.0.21, 4.0.17, 4.0.1 [master repo]
When I was using SplunkMint I had the same crash but switching to SplunkMint-iOS fixed it. I don't know what the differences are between the two Pods (I didn't even have to change my code initializing Mint) but I filed a bug to Splunk to let them know about it.
I will edit my post if I find something else,
Hope this will help,
Update: Splunk Mint (formerly BugSense) is investigating. They said there may be a bug and that is why you can see SplunkNSURLConnectionSendSynchronousRequestReturningResponseError and URLBlackListManager in there. I'll edit in what they ultimately have to say.

We've got kind of a weird bug in our app that only one user encounters so far (out of thousands) and I can't figure it out how to solve this, so maybe you can help me further.
It's about the following crash (run-time):

Line 149 of Loader.swift is:
let createDate : Foundation.Date = dateFormatter.date(from: eventCreated)!
It looks like it's an internal problem inside libswiftFoundation.dylib.
I've researched a lot about this problem and the only thing I could find on this was from Apple:
Some Objective-C methods in the SDKs may incorrectly annotate or assume a type to be nonnull rather than nullable. A type that Swift treats as a struct, such as NSURL (Foundation.URL) or NSDate (Foundation.Date), results in a run-time crash in a method with a name like bridgeFromObjectiveC; in other cases, it can lead to crashes or undefined behavior in user code. If you identify such a method, please file a report at bugreport.apple.com. As a workaround, add a trampoline function in Objective-C with the correct nullability annotations. For example, the following function will allow you to call FileManager'senumerator(at:includingPropertiesForKeys:options:errorHandler:) method with an error handler that accepts nil URLs:
https://developer.apple.com/library/content/releasenotes/DeveloperTools/RN-Xcode/Chapters/Introduction.html (under known issues)
With an example that looks like this:
static inline NSDirectoryEnumerator<NSURL *> * _Nullable
fileManagerEnumeratorAtURL(NSFileManager *fileManager, NSURL * _Nonnull url, NSArray<NSURLResourceKey> * _Nullable keys, NSDirectoryEnumerationOptions options, BOOL (^ _Nullable errorHandler)(NSURL * _Nullable errorURL, NSError * _Nonnull error)) {
return [fileManager enumeratorAtURL:url includingPropertiesForKeys:keys options:options errorHandler:^(NSURL * _Nonnull errorURL, NSError * _Nonnull error) {
return errorHandler(errorURL, error);
}];
}
I've already submitted a bug report for this issue, but still haven't got a response from Apple (after 7 days). I think this could fix the problem, but I'm not sure on how to port the given trampoline function (example) to a valid/working NSDate/DateFormatter version. Does someone know more about this problem and/or got it solved?
I'm seeing a segfault from using NSLog and specifically, it is on a 64 bit device, with a SEGV_ACCERR. I'm new to iOS, so i'm a little confused.

Here is the code that calls this:
NSString *truncated = [NSString stringWithUTF8String:buffer];
// Using original NSLog to print.
#undef NSLog
NSLog(#"%#", truncated);
and it crashes from my NSLog call.
where buffer is just a char buffer.
My questions specifically are:
Is it even possible to crash from using Apple's provided NSLog? Or is my stack trace wrong?
What does SEG_ACCERR even mean in this context?
How could i go about finding if this was caused by a bad memory issue or not?
Is something blowing up with the asl file under multiple threads?
How should i approach debugging this?
Any help would be greatly appreciated! Thanks!
You say that buffer is a char buffer. If that is the case, you should initialize the string like this
NSString *truncated = [[NSString alloc] initWithBytes:buffer
length:len NSUTF8StringEncoding];
where len is the length of the characters in the buffer.
I developed a DataMatrix Reader for Android with ZXING, and works fine, now I'm working in the version of iOS, but I have this errors when I want to use the library inside my project:
iOS SDK 8.1 and Library
ZXING: https://github.com/TheLevelUp/ZXingObjC
I use the COCOAPODS:
platform :ios, '7.0'
pod 'ZXingObjC', '~> 3.0'
I implemented the library in my project with Cocoapods, now I want to use in my App like this:
#import "ViewController.h"
#import "ZXingObjC.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)scanBarcode:(id)sender {
CGImageRef imageToDecode; // Given a CGImage in which we are looking for barcodes
ZXLuminanceSource *source = [[[ZXCGImageLuminanceSource alloc] initWithCGImage:imageToDecode] autorelease];

// The barcode format, such as a QR code or UPC-A
ZXBarcodeFormat format = result.barcodeFormat;
} else {
// Use error to determine why we didn't get a result, such as a barcode
// not being found, an invalid checksum, or a format inconsistency.
}
}
#end
but I have this error:

Now the question is somebody tried to integrate the ZxingObjC in iOS 8.1?
I think your project is using ARC but ZXING library isn't. In that case go to path 'Target -> Build Phases -> Compile Sources' in ZXING library. Double click on each .m file and enter '-fno-objc-arc' in popped dialog box. In this way those files will be excluded from ARC
If you project is using ARC (Automatic Reference Counting) then you don't need to make autorelease calls as it is done for you.
Change
ZXLuminanceSource *source = [[[ZXCGImageLuminanceSource alloc] initWithCGImage:imageToDecode] autorelease];
to
ZXLuminanceSource *source = [[ZXCGImageLuminanceSource alloc] initWithCGImage:imageToDecode];
Further information about ARC can be found on the iOS Developer Library
This works perfectly for me:
Getting Started in the readme.md didn’t work so I had to do the following steps to make it work.
copy the whole folders into your working project’s sub-folder.
and drag/add ZXingObjC.xcodeproj file to “<your working project>”.
make sure tick create folder references for any added folders option when prompted.
then, go to your project’s Target > Build Phases
under Target Dependencies, add ZXingObjC-iOS (ZXingObjC)
under Link Binary With Libraries, add libZXingObjC-iOS.a
under the same category, add the following 6 frameworks
AVFoundation.framework
CoreGraphics.framework
CoreMedia.framework
CoreVideo.framework
ImageIO.framework
QuartzCore.framework

My test in a direct device Iphone 4s were good, perhaps is not the best device to test that, Iphone 4s has not a "AutoFocus" feature, very important for work with this barcodes.
hope this saves your day.

I am loading the Paginator like this:
- (void)fetchLatestPlantsWithCount:(NSNumber *)count
{
RKObjectManager *objectManager = [RKObjectManager sharedManager];
NSString *requestString = [NSString stringWithFormat:#"/api/rest/plants/?count=%#&limit=:perPage&offset=:offset", count];
NSDictionary *parameters = nil;
if(_dateFilterLastModifiedAppend)
parameters = [[NSDictionary alloc]initWithObjectsAndKeys:_dateFilterLastModifiedAppend, #"last_modified_date__gte", nil];
RKPaginator *paginator = [objectManager paginatorWithPathPattern:requestString parameters:parameters];
paginator.perPage = API_PER_PAGE_LIMIT;
[ZAActivityBar showWithStatus:[NSString stringWithFormat:NSLocalizedStringFromTable(#"Downloading latest plants: %# remaining", #"PokaLocalizable", nil), count]];
[paginator setCompletionBlockWithSuccess:^(RKPaginator *paginator, NSArray *objects, NSUInteger page) {
if([paginator hasNextPage])
{
[ZAActivityBar showWithStatus:[NSString stringWithFormat:NSLocalizedStringFromTable(#"Downloading latest plants: %# remaining", #"PokaLocalizable", nil), [NSNumber numberWithInt:([count integerValue] - paginator.offset)]]];
[paginator loadNextPage];
}
else
{
[self fetchLatestProductionLinesCount];
}
} failure:^(RKPaginator *paginator, NSError *error) {
[self fetchLatestProductionLinesCount];
}];
[paginator loadPage:1];
}
Finally, I added some code to RestKit in order to load the paginator. I don't think it is the problem though.
- (RKPaginator *)paginatorWithPathPattern:(NSString *)pathPattern parameters:(NSDictionary *)parameters
{
NSAssert(self.paginationMapping, #"Cannot instantiate a paginator when `paginationMapping` is nil.");
NSMutableURLRequest *request = [self requestWithMethod:#"GET" path:pathPattern parameters:parameters];
RKPaginator *paginator = [[RKPaginator alloc] initWithRequest:request paginationMapping:self.paginationMapping responseDescriptors:self.responseDescriptors];
#ifdef _COREDATADEFINES_H
paginator.managedObjectContext = self.managedObjectStore.mainQueueManagedObjectContext;
paginator.managedObjectCache = self.managedObjectStore.managedObjectCache;
paginator.fetchRequestBlocks = self.fetchRequestBlocks;
#endif
paginator.operationQueue = self.operationQueue;
Class HTTPOperationClass = [self requestOperationClassForRequest:request fromRegisteredClasses:self.registeredHTTPRequestOperationClasses];
if (HTTPOperationClass) [paginator setHTTPOperationClass:HTTPOperationClass];
return paginator;
}
The only difference is that I pass some parameters to it.
The thing I don't understand is that I load other objects, WITH that same code with the only difference being the type of objects I am downloading. I execute almost that same code right before executing this one, and it works perfectly fine. Hence, my question as to I am confused...
Some more information:
It says the object count is 1, that page is 1, but apparently it is not loaded?
Note that I call the paginator multiple times within the same page. I do the paginator for one type of objects... once it is done I do it for another one... and so on.
All pull requests that I mentioned before were merged already to master. So just use the newest version.
I found an issue and fixed it if you are interested. I posted Pull Request on RestKit github page
https://github.com/RestKit/RestKit/pull/2156
I would recommend to use my fork on branch inventorum where I also cherry picked malloc error fix:

I'm new to ios development and to stackoverflow. I did try searching both stackoverflow and google before posting.
I built a simple little app, originally just left it an iphone only app, but decided to make it universal in the end. I, stupidly, was messing around when i was getting to know xcode 4 and switched it to universal and then back again so i had to recopy the project and do it again. This time i started it with a universal app. (Not when i created it but after i went to project and selected it there) It created the ipad folder and mainwindow-ipad.xib file but was empty of course since i didn't do anything yet. I had it set up as a tabbed based app so my iphone version had firstview and secondview nib files also, but the ipad version didn't. I set it all up in iphone version first and it worked fine. I then went and laid down the ipad version (i did eliminate the second tab from mainwindow-ipad because i didn't need it)
i then went and created a new nib file and placed it in the ipad folder along with "main-ipad.h" and "main-ipad.m". I copied my code and connected everything and it runs fine on ipad simulator but now when i try and run iphone simulator i get "SIGABRT error. I took a screen shot of it. I don't fully understand objective-c so i was hoping someone can help me? I can post any code or whatever you might need to help me with this error so just ask.
Appreciate any help and suggestions you may have!
Thanks!
[Okay i would have posted image but I can't since I'm a new user, instead i posted the line highlighted and the output from xcode]
Code for file with error:
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil); //ERROR IS ON THIS LINE <-----
[pool release];
return retVal;
}

Thanks again! If anyone has any suggestions for my code i'd love to here them! Like I said, I'm new to it and thats the only way i know to do this.
------------> If anyone wants, I'll upload the entire project folder. Just ask. Thank you guys for all the help. i'm a n00b with xcode so i haven't got it all down yet.
Project Zipped
Post some code where you use finallabel and try to debug your app so you can tell me the line just before the app crashes.
Option 2:
Try to set a BreakPoint in malloc_error_break so we can have more info about the error.
In XCode go to Run -> Show -> BreakPoints (or just cmd + option + B). Then double click to add a new symbol (symbolic breakpoint) and type in malloc_error_break then press enter.
Now run your app and paste your console text.
UPDATE If you need help http://developer.apple.com/library/mac/#recipes/xcode_help-breakpoint_navigator/articles/adding_a_symbolic_breakpoint.html
Check your connections inside your InterfaceBuilder, you may have it wrong with fianllabel.
Also check your Custom Class -> Class in your iphone XIB in your InterfaseBuilder
UPDATE
Go to Product -> Clean. Then Run.
The line UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); just means that an exception was thrown during the running of your program. This could range from a memory problem, to a simple runtime error. Look in the target debugger console; it will tell you where the error occurred.
Open "iOS Simulator" Menu in the upper left->Reset Content and Settings. Then quit the iOS simulator and Xcode, and then restart your computer. This will get rid of the other instance of the process.
This May work it's work for me...........
The problem is with your XIB file. This error generally occurs when your finalLabel is incorrectly hooked up or doesn't exist anymore. Check your connections in the Interface Builder once.
I also had this error. After spending so much time, I found how to fix it. First of all go the console and see where is the error (mine was related to storyboards and its code) The way I fixed my error was by going in story board. Below the iPhone screen, there will be small yellow button. Right click on it and you will see that is causing error. Delete(x) it if there is yellow error sign.
If this does not fix your error then try to make new project and then replace its blank files with old files of your old project. I had same error in very beginning and by doing this program run without any error.
Other people suggests by restarting your laptop and running it again, reseting the iOS simulator, or changing iOS debugger (however this does not work in latest x code since there is only one debugger)
Hope this helps
