Solving XCode4.2 upgrade warnings; importing flurry analytics; etc.

Welcome to my blog! If you've stumbled across this (or any blog) in your travels on the internet, place take a moment click on an ad -or two! You might see something you like, *and* it helps finance the blogosphere. Think of the children.

Ok, well, today, I've just released my first free version of my app. It give the first 100 for free, but you need to pay for the rest. But, I need to make it clearer when you run out, like an alert. As it stands now, you just have to keep repeating, trying to figure out why you're stuck. I went through 3 of the same quiz before I finally got it, and I wrote the program.

So, the goal of today is to put in an alert. I also want to put in some metrics.

Woah - thank God. A gang of like 20 high school girls just decided *not* to sit right next to me. That was a close call.

Oh, yeah, I almost forgot. Since I upgraded to Xcode 4.2, I've been getting warnings from the Reachability class:

declaration of '…' will not be visible outside of this function warning

Stackoverflow as usual has the solution:

Add #import <netinet/in.h> in Reachability.h to get away with this

Ok, there are still a couple of other warnings.

I'm getting an incompatible pointer warning on this:

UIScrollView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];

If I click on the warning, it takes me to the class itself, which returns a UIView. So casting it to a UIScrollView eliminates the problem:

UIScrollView *view = (UIScrollView *) [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];


Ok, good. Now, the last warning is

"initwithframe reuseidentifier is deprecated" from this statement:

cell = [ [[UITableViewCell alloc]
initWithFrame:CGRectZero reuseIdentifier:@"cell"] autorelease];

The fix, again from stackoverflow, is this:

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"] autorelease];

Whew! That was pain.

Ok, where was I? Ok, first, let's throw in the alert.

Here's where I want to throw it in:

if (reachedEndOfFreeWords) {
if ([Utils isFreeVersion]) {
self.upperCongratsMessage.text = @"Free vocabualary completed!";
self.congratsMessage.text = @"Click the buy button below for the rest!";

=========> create the alert here! <=====================

}
else {
self.congratsMessage.text = @"You have completed *all* the words!";
}
}

Ok, let's get some alert code. Where do we have it? Hmm...right - there's an alert if you don't get all the question right.

Ah, here it is:

// construct a message letting the user know how many were wrong
NSString *title = [NSString stringWithFormat:@"You answered %d out %d correctly",appState.correctAnswers, [appState.shuffledQuestionDictKeyList count]];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:@"To advance, all answers must be correct"
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];

[alert show];
[alert release];

So, let's make this look like this:

// construct a message to the user
NSString *title = [NSString stringWithFormat:@"Press the
\"Buy\" button below for the rest of the questions!";

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:@"Congratulations - free questions completed."
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];

[alert show];
[alert release];

Ok, with that taken care of, let's set up the metrics.

Pretty easy - copy the libFlurryAnalytics.a into the project, copy the FlurryAnalytics.h into the app delegate implementation file, and the start session in the "application:didFinishLaunchingWithOptions method:

[FlurryAnalytics startSession:@"YOUR_KEY_GOES_HERE"];

Ok, that's a wrap. Check out the ads!
