This code works perfectly when I build & run from Xcode, or when I right click the "product" from within Xcode. However when I run the application from the finder it never launches ... Even from within the very build folder.. wtf ?
Don't use currentDirectoryPath to find your resources directory.
NSString *appPath = [[NSBundle currentBundle] pathForResource:#"systemRun" ofType:#"app"];

I'm making a simple launcher for a binary so I can have it appear in my launchpad.
My initial thought was that running system("./myProgram"); would be sufficient, but it doesn't appear to actually do anything as the terminal instance it runs doesn't stay open after running the command, immediately shutting down whatever other tasks the program did.
So my question is, is there a way for me to do this that keeps it open indefinitely?
Edit: I want my launcher to close immediately after launching the program, so it would be less than ideal to rely on something that requires it to stay open
Edit: the following all work, but only when run from xcode, when running it stand-alone it doesn't launch the program at all
system("open /Applications/Utilities/Terminal.app myProgram");
system("open myProgram");
system("/bin/sh -c ./myProgram&");
system("./myProgram&");
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath: #"/bin/bash"];
[task setArguments: #[#"-c", #"./myProgram"]];
[task launch];
NSTask does not give any errors, and it doesn't throw any exceptions either when the app runs
Literally every other aspect of the program works, it just won't launch, and it won't say why
Based on all the "feedback" here's what I got so far. And it still doesn't work unless I provide an absolute path (which is no good in case I want to move it later)

Hacky solution that works (but isn't elegant at all)
I had to replace
FILE_PATH = [CURRENT_DIR stringByAppendingString: INIT_PATH];
With
CURRENT_DIR = [[[[NSBundle mainBundle] bundlePath] stringByDeletingPathExtension] stringByDeletingLastPathComponent];
To get the correct path for the file, but it works now.
I am using thisopen source control called Vfr Reader to show pdf files in my app. All was working on iOS 7. After iOS update app crashes when I try on open a pdf file.
I am using this code to initialize pdf reader.
NSString *fileName = [[NSBundle mainBundle] pathForResource:#"PdfName" ofType:#"pdf"];
ReaderDocument *document = [ReaderDocument withDocumentFilePath:fileName password:nil];
if (document != nil)
{
ReaderViewController *readerViewController = [[ReaderViewController alloc] initWithReaderDocument:document];
readerViewController.delegate = self;
readerViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
readerViewController.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:readerViewController animated:YES completion:Nil];
}
App crashes in this fuction of vfr
+ (NSString *)relativeFilePath:(NSString *)fullFilePath
{
assert(fullFilePath != nil); // Ensure that the full file path is not nil
NSString *applicationPath = [ReaderDocument applicationPath]; // Get the application path
NSRange range = [fullFilePath rangeOfString:applicationPath]; // Look for the application path
assert(range.location != NSNotFound); // **Crashes here**
return [fullFilePath stringByReplacingCharactersInRange:range withString:#""]; // Strip it out
}
On crash debugger shows these values.
fullFilePath = #"/Users/GuruTraxiOSDev01/Library/Developer/CoreSimulator/Devices/CC9412A6-9A95-4F46-89BA-8ECC13D0AF19/data/Containers/Bundle/Application/D2DC440B-F010-4575-93FD-3CB05BFF4F78/AppName.app/PdfName.pdf" 0x798c9b30

I already confirmed the file's existence.
Can anyone help please!
EDIT: This question solved crash on file load. But app still crashes on
CGContextDrawPDFPage(context, thePDFPageRef);
I was facing the same issue, so I made some changes to the Library Files which should not be an option as such but in this case I didn't have any choice to get it to work. So to make your code work follow the instruction below:
Go to ReaderDocument.m file and make the following changes:
+ (NSString *)documentsPath
{
//Make changes to return the NSBundle path.
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSFileManager *fileManager = [NSFileManager new]; // File manager instance
NSURL *pathURL = [fileManager URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:YES error:NULL];
// return [pathURL path]; // Path to the application's "~/Documents" directory // Code changes.
return bundlePath;
}
If you had a breakpoint just delete it, that solve it for me.
Breakpoint navigator => select the breakpoint then delete
After implementing the HCDownload for iOS into my app I am successfully able to display the downloading progress of a file.
The problem is that the guy who wrote it, didn't use Xcode to write the module, so even though it should, it does not really work nice when trying to integrate with a project.
These are the main issues I have with it:
If you do a [self.navigationController pushViewController:dlvc animated:YES]; or a [self presentViewController: animated: completion:]; then it shows when it is initiated. I can get out of it, by navigating back, but then when I return to it, it is blank - so I cannot see what the progress is of the download. The download however keeps going, because it appears in my documents folder. ( I use ASIHTTP framework)
Now I am working with storyboard in this project, and because this does not come with a XIB file I thought (which has kinda worked in the past) I could just have a UITableViewController and have this as its Custom Class, but it does not play ball.
Is there a XIB based Download manager FrameWork that someone can point me too, or has anyone had luck with this one?
PS I know Storyboards do not use XIB files, but that way it is easier to integrate into storyboard than no UI files at all:-)
Kind thanks for the tips.
Edit
Here is the code where I implement it:
HCDownloadViewController *dlvc = [[HCDownloadViewController alloc] init];
dlvc.delegate = self;
NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
dlvc.downloadDirectory = documentDirectory;
NSString *fileSave = [_streamingURL lastPathComponent];
NSURL *url = [NSURL URLWithString:_streamingURL];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[dlvc downloadURL:url userInfo:nil];
// Add your filename to the directory to create your saved pdf location
NSString *pdfLocation = [documentDirectory stringByAppendingPathComponent:fileSave];
NSString *cachesDirectory = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
// Add your filename to the directory to create your temp pdf location
NSString *tempPdfLocation = [cachesDirectory stringByAppendingPathComponent:fileSave];
if (!networkQueue) {
networkQueue = [[ASINetworkQueue alloc] init];
}
failed = NO;
[request setTemporaryFileDownloadPath:tempPdfLocation];
[request setDownloadDestinationPath:pdfLocation];
[request setDownloadProgressDelegate:progressBar];
[request setShowAccurateProgress:YES];
How do I gain access to a crashSound.wav file I've put in my Supporting Files folder of my xCode Project? Because the following code isn't working :
#interface Game()
{
// code...
AVAudioPlayer *crashSound;
// code...
}
#end
#implementation Game
- (id) init
{
// code...
NSURL *crashSoundFile = [[NSURL alloc] initWithString:#"crashSound" ]; // <--PROBLEM
crashSound = [[AVAudioPlayer alloc] initWithContentsOfURL:crashSoundFile error:NULL];
// code...
}
-(void) play // this is my "main" method that will be called once the playButton is pressed
{
[crashSound play];[crashSound play];[crashSound play];
}
#end
#"crashSound" is not a valid URL. You must supply an actual URL.
URLs to images, sounds, etc. (resources) in your project are not predictable at compile-time, and must be generated at run-time. This is easy using NSBundle.
NSBundle *bundle = [NSBundle mainBundle];
NSURL *crashSoundFile = [bundle URLForResource: #"crashSound" withExtension: #"wav"];
Ta da.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/soundfile.extension", [[NSBundle mainBundle] resourcePath]]];
I'm trying to write to a plist file using writeToFile, before I write I check whether the file exists.
This is the code:
#import "WindowController.h"
#implementation WindowController
#synthesize contacts;
NSString *filePath;
NSFileManager *fileManager;
- (IBAction)addContactAction:(id)sender {
NSDictionary *dict =[NSDictionary dictionaryWithObjectsAndKeys:
[txtFirstName stringValue], #"firstName",
[txtLastName stringValue], #"lastName",
[txtPhoneNumber stringValue], #"phoneNumber",
nil];
[arrayContacts addObject:dict];
[self updateFile];
}
- (void)awakeFromNib {
NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
filePath = [rootPath stringByAppendingPathComponent:#"Contacts.plist"];
fileManager = [NSFileManager defaultManager];
contacts = [[NSMutableArray alloc] init];
if ([fileManager fileExistsAtPath:filePath]) {
NSMutableArray *contactsFile = [[NSMutableArray alloc] initWithContentsOfFile:filePath];
for (id contact in contactsFile) {
[arrayContacts addObject:contact];
}
}
}
- (void) updateFile {
if ( ![fileManager fileExistsAtPath:filePath] || [fileManager isWritableFileAtPath:filePath]) {
[[arrayContacts arrangedObjects] writeToFile:filePath atomically:YES];
}
}
#end
When the addContactAction is executed I don't get any error but the program halts and it brings me to the debugger. When I press continue in the debugger I get:
Program received signal: “EXC_BAD_ACCESS”.
But that's probably not important.
PS: I'm new to mac programming and I don't know what else to try since I don't get an error message that tells me what's going wrong.
The path to the file is:
/Users/andre/Documents/Contacts.plist
I earlier tried this(with the same result), but I read that you can only write to the documents folder:
/Users/andre/Desktop/NN/NSTableView/build/Debug/NSTableView.app/Contents/Resources/Contacts.plist
Does anyone have an idea or even an explanation why this happens?
First, I think you shouldn't instantiate an NSFileManager object. Instead you use the default file manager, like this:
[[NSFileManager defaultManager] fileExistsAtPath: filePath];
Then, could you specify at which line the program is breaking into the debugger?
You are setting filePath with the stringByAppendingPathComponent: method. That method returns an autoreleased object. (Autoreleased object is used after it has been (automatically) released, which could cause the bad access error.)
I think changing
[rootPath stringByAppendingPathComponent:#"Contacts.plist"];
into
[[rootPath stringByAppendingPathComponent:#"Contacts.plist"] retain];
will solve your troubles.
