Declare and set a variable called myName to your name
Declare two more string variables introduction and japaneseIntroduction both with an NSString type
Set introduction using stringWithFormat class method "My name is %@", myName
Set japanese introduction using stringByAppendingString instance method by appending " to moushimasu"
Print introduction and japanese introduction
Step 3: Define and call a new function
Declare a function called printIntroductions
The function should accept an NSString as a parameter called name
Cut and paste the introduction and japaneseIntroduction code inside of the new function
You should have errors for referencing 'myName'. Change any reference to 'myName' to 'name'.
This is an error of scope. You only declared 'myName' in your didFinishLaunching method. Not in your new method. In your new method, you declared an argument called 'name' that your function accepts when the method is called
In your didFinishLaunching method after you set myName call printIntroductions: and pass in 'myName' as an argument
It should print out the introduction and Japanese introduction
Step 4: Recurse through a function
Add a new function called countDownTillIntroduction: that accepts an integer called numberOfDays as an argument
The function should do the following:
Check to see if the numberOfDays is 0
If the number of days is 0, it should print "The time has come"
If numberOfDays is not 0
It should print "[numberOfDays] days left until introductions"
It should declare and set a variable oneLessDay and set it to numberOfDays - 1
It should then call countDownTillIntroduction and pass in oneLessDay
In the didFinishLaunching method before you call printIntroductions call countDownTillIntroduction and pass in 4
OUTPUT: You should see it print "4 days left until introductions", "3 days left until introductions" (down to 1) and then it should print "The time has come" and "My name is [yourName]", "[yourName] to moushimasu"
What is your expectation here? Do you want someone to write that program for you? That will not happen. You should try it yourself and if you then run into a specific problem, come back, ask a specific question and probably someone can help you with that.
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.
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.
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.
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?
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?
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.
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!
