Is it possible to design an iPad app that launches Safari, waits until a dialog box appears in Safari and then activates a button. Waits until another dialog box appears and then automatically completes the username and password in Safari and finally the app closes itself?
I cannot use Autofill as the website that Safari has accessed does not allow saving passwords. An analogy would be Safari automatically connecting to one's banks website that does not allow saving username and passwords.
This is an app I am trying to develop for visually impaired people for easy login access to the local library.
All constructive comments are welcome.

To the best of my knowledge the short answer is no.
If it were possible then I highly doubt that you would be able to get this released into the Store because of the privacy concerns that something like this could create.
If this is your app and web site then there are other alternatives available for you to try. From your app you could launch a website and pass in parameters via the url. Then on your website have some javascript that runs and takes care of what remains.
Though of course you will have the issue of passing passwords as free text via the url. Definitely requires some more more thought but alas that is for another thread.

to my knowledge this is not possible.
I saw some password tools (like 1Password, LastPass) on the appstore that opens up a website on an internal browser and then fill in the username and password.
But to my knowledge apple doesen't allow IPC between most of the Apps. The only place where Apps are communicating is AppleHealth where 3th party apps could write to AppleHealth.
If you find a way to opening up safari and then fill in the user and password boxes i'm extremly interested in the solution!

I'm trying to make a pretty simple frontend program that's able to start up a java program when it's run, but haven't yet mastered OC. Someone suggested that I try using a console command (code below), but I haven't been able to make that work yet.
Is there an easier way to do this, or does any one here know where my code has gone wrong?
int main(int argc, const char * argv[]) {
NSFileManager *filemgr;
NSString *currentpath;
filemgr = [[NSFileManager alloc] init];
currentpath = [filemgr currentDirectoryPath];
NSPipe *pipe = [NSPipe pipe];
NSFileHandle *file = pipe.fileHandleForReading;
NSTask *task = [[NSTask alloc] init];
task.launchPath = [currentpath stringByAppendingString:@"/java"];
task.arguments = @[@"-jar", @"PolyGlot.jar"], [NSString stringWithFormat:@"%c", argv]];
task.standardOutput = pipe;
[task launch];
NSData *data = [file readDataToEndOfFile];
[file closeFile];
NSString *grepOutput = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog (@"grep returned:\n%@", grepOutput);
return 0;
}
When I run this, I get the error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'launch path not accessible'
I know that the current path is accessible, though... so I'm kind of stumped here. Any help would be much appreciated. Thanks!

As a guess because what you think is the current path for the executable is not in fact the path where the jar actually is.
|
|
|
|
|
Part of the trouble I'm having here is that I'm ultimately trying to reproduce the Terminal line:
java -jar PolyGlot.jar <FILENAME_ARGUMENT >
Do you have any ideas for that? Any help would be appreciated.
|
|
|
|
|
task.launchPath = [currentpath stringByAppendingString:@"/java"];
Are you sure that the java executable is in that path? Printing out the full path at that point will tell you.

Ah, I do see what I was doing there! I was fundamentally misunderstanding how java was being referenced. I almost have it working at this point! Here's the code as it stands now:
int main(int argc, const char * argv[]) {
NSFileManager *filemgr;
NSString *currentpath;
filemgr = [[NSFileManager alloc] init];
currentpath = [filemgr currentDirectoryPath];
NSPipe *pipe = [NSPipe pipe];
NSFileHandle *file = pipe.fileHandleForReading;
NSTask *task = [[NSTask alloc] init];
task.launchPath = @"/usr/bin/java";
task.arguments = @[@"-jar", [currentpath stringByAppendingString:@"/PolyGlot.jar"], [NSString stringWithFormat:@"%c", argv]];
task.standardOutput = pipe;
[task launch];
NSData *data = [file readDataToEndOfFile];
[file closeFile];
NSString *grepOutput = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog (@"grep returned:\n%@", grepOutput);
return 0;
}
The only remaining problem is that the "-jar" argument seems to be ignored at this point. If I apply it by itself, Java recognizes it as an argument, but otherwise, it is only accepting "PolyGlot.jar". Is there something that I'm not doing correctly there?
Thanks for the help so far!

I don't know Objective-C, but I suspect that the first argument should be the same as task.launchPath, i.e the program name. That would then comply with the format of the argv array, as set by the shell when invoking programs from the command line.

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.

And I think those are the fields that you need in your arguments array. The last parameter you specify should be argv[1] as a string (%s), not a character (%c), as that is the filename passed in to your program. Something like:
task.launchPath = @"/usr/bin/java";
task.arguments = @[task.launchPath, @"-jar", [currentpath stringByAppendingString:@"/PolyGlot.jar"], [NSString stringWithFormat:@"%s", argv[1]]];

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!

I think there is an problem in executable path..Check out that

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 a=1;
int b=5.14;
int c = -.015;
int w =1;
int r =.73;// on=.73 and off= .66
int h=1;
int result;
result = (a * b/w * r) c * h;
NSLog (@"a*b/w*r)c*h;");
Is this possible

Most likely but your question is far from clear. In general terms you would write something like:
if (switch == ON)
r = .73;
else
r = .66;
But maybe I just don't understand what you are asking.

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.

Google will find you lots of documentation on both languages.

I don't think so. It's quite reasonable to want to learn the differences, just a pity he/she (like so many others) can't make the effort to do a bit of research.

Nothing wrong with his question.
But I checked his user id, signature in his message & links in his profile so thought ....
|
|
|
|
|
after looking at his signature I am thinking the same thing about this being spam now.
|
|
|
|

I disagree, the question has nothing in it that could be construed as spam. And there are quite a few members who have links to their own business in their signatures.
