  • Having an issue while trying to implement In-App Purchase

    - by Raymond
    This is my first time to implement In-App purchase and I am using the tutorial located here: Ray Wenderlich Now I am sure this is something simple, but I am having issues figuring out, so I figured I would ask all of the gurus out here. The compiler is saying that _products is Use of undeclared identifier - (void)productPurchased:(NSNotification *)notification { NSString * productIdentifier = notification.object; [_products enumerateObjectsUsingBlock:^(SKProduct * product, NSUInteger idx, BOOL *stop) { if ([product.productIdentifier isEqualToString:productIdentifier]) { *stop = YES; } }]; }

  • How does this script work for the ImageShack.us API?

    - by vette982
    I'm looking into using the ImageShack.us API for uploading images from my website. I found this tutorial for using it with the XML return http://elliottback.com/wp/using-the-imageshack-xml-api/, but I'm not sure about what to do with it. Where do I enter my API key for this script? Furthermore, he shows the use of two PHP files - should these be combined into one file? Any help with this would be appreciated (examples would be even better).

  • Firefox extension, need advice

    - by edc
    I've never built a ff extension before and before I start I want some feedback on my idea to make sure its possible. I want a firefox extension that allows me to supply a url with parameters in GET format, the extension would take the url, parse it, and submit the request as POST rather than GET. Is this possible? and could someone give me some advice on how to start designing an extension? or point me at a tutorial?

  • Passing variables, creating instances, self, The mechanics and usage of classes: need explenation

    - by Baf
    I've been sitting over this the whole day and Im a little tired already so please excuse me being brief. Im new to python. I just rewrrote a working program, into a bunch of functions in a class and everzthings messed up. I dont know if its me but Im very surprised i couldn t find a beginners tutorial on how to handle classes on the web so I have a few questions. First of all, in the init section of the class i have declared a bunch of variables with self.variable=something. Is it correct that i should be able to access/modify these variables in every function of the class by using self.variable in that function? In other words by declaring self.variable i have made these variables, global variables in the scope of the class right? If not how do i handle self. ? Secondly how do i correctly pass arguments to the class? some example code would be cool. thirdly how do i call a function of the class outside of the class scope? some example code would be cool. fouthly how do I create an Instance of the class INITIALCLASS in another class OTHERCLASS, passing variables from OTHERCLASS to INITIALCLASS? some example code would be cool. I Want to call a function from OTHERCLASS with arguments from INITIALCLASS. What Ive done so far is. class OTHERCLASS(): def __init__(self,variable1,variable2,variable3): self.variable1=variable1 self.variable2=variable2 self.variable3=variable3 def someotherfunction(self): something=somecode(using self.variable3) self.variable2.append(something) print self.variable2 def somemorefunctions(self): self.variable2.append(variable1) class INITIALCLASS(): def __init__(self): self.variable1=value1 self.variable2=[] self.variable3='' self.DoIt=OTHERCLASS(variable1,variable2,variable3) def somefunction(self): variable3=Somecode #tried this self.DoIt.someotherfunctions() #and this DoIt.someotherfunctions() I clearly havent understood how to pass variables to classes or how to handle self, when to use it and when not, I probably also havent understood how to properly create an isntance of a class. In general i havent udnerstood the mechanics of classes So please help me and explain it to me like i have no Idea( which i dont it seems). Or point me to a thorough video, or readable tutorial. All i find on the web is super simple examples, that didnt help me much. Or just very short definitions of classes and class methods instances etc. I can send you my original code if you guys want, but its quite long. Thanks for the Help Much appreciated!
