I have the exact same problem as a earlier question xcode swift indexing forever
i have spotted my problem. This array:
var VragenInformatie = [[["Spelletjeskamer",""],["Keuken",""],["Garage",""],["Binnenplaats",""],["Zitkamer",""],["Slaapkamer",""],["Studeerkamer",""],["Eetkamer",""],["Badkamer",""]], [["De Wit",""],["Pimpel",""],["Blaauw van Draet",""],["Roodhart",""],["Groenewoud",""],["Van Geelen",""]], [["Loden pijp",""],["Pistool",""],["Engelse sleutel",""],["Dolk",""],["Touw",""],["Kandelaar",""]]]
I have tried: clean, deleted derived data, and even delete workspace thingy
but nothing worked. But I still need this array does anybody have an idea or suggestion how to get a work around?
UPDATE:
I gone use this array for a tableview so is there maybe an other way for tableview data source?
Thanks in regards!
I think, the problem is the type inference, which is quite hard for your 3D array. You should give more structure to this, e.g. via tuples
let VragenInformatie: [[(String, String)]] = [
[("Spelletjeskamer",""), ("Keuken",""), ("Garage",""), ("Binnenplaats",""), ("Zitkamer",""), ("Slaapkamer",""), ("Studeerkamer",""),("Eetkamer",""), ("Badkamer","")],
[("De Wit",""), ("Pimpel",""), ("Blaauw van Draet",""), ("Roodhart",""), ("Groenewoud",""), ("Van Geelen","")],
[("Loden pijp",""), ("Pistool",""), ("Engelse sleutel",""), ("Dolk",""), ("Touw",""), ("Kandelaar","")]
]
Anyway, not a neat, clean design. Think about creating a structure or class which encapsulate your data (sorry, my Dutch is not sufficient to understand what you try to provide to a table view).
So I am not very good with computers and have to create my first app for a project. It's going fine so far - essentially I am trying to create an app that records and saves data. Right now I'm still getting the record part down, since Xcode is having periodic issues. I am using this link for setting up the code:
http://www.techotopia.com/index.php/Recording_Audio_on_iOS_7_with_AVAudioRecorder
Unfortunately, I am running into 2 types of semantic errors, two red, two yellow. They are all in RecordModelController.m - the first is like this:
return [self.pageData indexOfObject:viewController.dataObject];
Xcode claims that Property 'dataObject' isn't found in any object or forward class in 'RecordDataViewController'. That's actually my two red errors, they just sound very similar so I paraphrased them into one. The yellow error, however, repeats itself twice on the same line of code, which is:
return [self viewControllerAtIndex:index storyboard:viewController. storyboard];
The yellow issues on these lines of code (again, repeated twice) is "Incompatible pointer types returning 'RecordDataViewController *' from a function with result type 'UIViewController *'" - I genuinely tried to look in RecordDataViewController.h and couldn't make sense of this. Like I said, bad with computers, not sure why I'm having this issue, and I know that it's probably something basic.
If anyone would be willing to help me out with how to deal with issues like this, that would be great. Thanks, and sorry for my incompetence.
The red are called errors. The yellow are called warnings. I'm going to suggest you look at a few beginning Xcode/iOS programming tutorials so you understand the basic concepts of how view controllers, arrays, etc. work in objective-c. The best place to start for someone completely new as yourself is here: http://www.raywenderlich.com/tutorials
Hope this helps!
maybe this is not the correct forum where to post this question, but i've serched for two weeks in the web, without results.
I need to make a kind of power point presentation, something like this - do know which program can i use?
Thank you
I think, that tool used for this prezentation can be find on
http://prezi.com/
This is called infographics and you can use website like visual.ly/
Then, you have to do your own effects
Is it possible to make a 2.5 component without using TableHelloWorld class and all that field type stuff like from here. Or is it compulsory?
http://docs.joomla.org/Developing_a_Model-View-Controller_Component/2.5/Using_the_database
The system will function without it fairly well actually. All you actually need to get something running is a base file named after your component, a controller.php file, and the view as outlined in this section: http://docs.joomla.org/Developing_a_Model-View-Controller_Component/2.5/Adding_a_view_to_the_site_part
From that you will get something that runs and loads. And if you choose you can just make raw sql queries to the database.
That being said, the framework is there to help you, not to hinder you. I've cut a lot of corners over the years, and almost always you end up regretting it later. Feel free to play around with skipping the pieces, but just remember that there are pieces out there that can help you with all kinds of important things that you may not think you need right now. (Binding input, table row hierarchies, and check-in/check-out functionality are just a few that come to mind that I'm glad I didn't have to make myself.)
I'm really stuck right now. I want to apply LIBSVM for Image Classification. I captured lots of Training-Images (BITMAP-Format), from which I want to extract features.
The Training-Images contain people who are lying on the floor. The classifier should decide if there is a person lying on the floor or not in the given Image.
I read lots of papers, documentary, guides and tutorials, but in none of them is documented how to get a LIBSVM-Package. The only thing that is described is how to convert a LIBSVM-Package from a CSV-File like this one: CSV-File. On the LIBSVM-Website several Example-Data can be downloaded. The Example-Data is either prepared as CSV-Files or as ready-to-use Training- and Testdata.
If you look at the Values which are in the CSV-File, the first column are the labels (lying person or not) and the other Values are the extracted features, but I still can't reconstruct how those values are achieved.
I don't know if it's that simple that nobody has to mention it, but I just can't get trough it, so if anybody knows how to perform the feature extraction from Images, please help me.
Thank you in advance,
Regards
You need to do feature extraction first. There are many methods that are available. These include LBP,Gabor and many more.. These methods will help you get the features to input into libsvm..Hope this helps...
