The task.launchPath is the full path of the program to be run. Out of curiosity, I tried dropping " -jar" onto the end, but that made it fail when it looked for the executable "java -jar" rather than the executable "java" with the argument "-jar".
What's strange is that the "-jar" argument works correctly so long as it's the only one... Ultimately, the error I'm getting from Java at this point is "
Could not find or load main class
". This typically appears if you try to run a .jar file without the -jar argument.
Also, just for the sake of sanity, I'll specify that I can run "java -jar PolyGlot <FILENAME>" from the console, and it runs fine.
I can run "java -jar PolyGlot <FILENAME>" from the console, and it runs fine.
And I think those are the fields that you need in your arguments array. The last parameter you specify should be argv as a string (%s), not a character (%c), as that is the filename passed in to your program. Something like:
As a heads up, I found my solution! It turns out that the debug folder that this was running in gave Java particular troubles, and the behavior cleared up when I took my compiled app into a typical folder. Thanks to everyone who replied for the help!

In objective-c I’m try to create a statement that toggles a variable that switches between two numbers with a UIswitch controller
(a * b/w * r) c * h;
r needs to trigger two different numbers
when on needs to = .73
when off needs to = .66
int c = -.015;
int w =1;
int r =.73;// on=.73 and off= .66
result = (a * b/w * r) c * h;
Is this possible
C and Objective-C have many differences.
First of all, C is procedure-oriented language while object-C is object-oriented language.
They have different syntaxes.
Objective-C is more familiar to smalltalk than C/C++.
e.g. of calling method
c: foo(param1, para2, ...);
objective-c: [object foo:param];
There are many differences between two languages.
hey all. i have an UIWebView(tarayici in my situation) in view controller. it works fine when its scroll view delegate is not assigned to view controller. but i need to know when it is scrolled that is why i wrote this code.
self.tarayici.scrollView.delegate = self;
but when i write this down then webview acts so weird. for example after this code when i want to scroll then it scrolls only once if i make 3 or 4 attempts. so how can make it work more efficient with that code ?
i think i found the solution. The commented UIview animation block locked the main thread i think that is why Scroll View couldnt response to the new touches. but with this new animation block it works well.
All of your questions really depend on what you are trying to accomplish when programming in Objective-C. If you are just using it as a language the answer is yes you can program with it on windows and linux.
However if you are looking to develop with the Cocoa frameworks and/or for iOS platforms then you will need:
1 - Apple hardware (mini, macbook, iMac, Pro)
2 - XCode will be the IDE that you most likely will want to start with if you are new and learning.
3 - You can get XCode from the App Store on your OSX machine.
