  • Level selection view - similiar to Angry Bird's

    - by Piotr
    I am making game and need to prepare view for level selection. Could you recommend me some opensource library which could I use? I need icons to vibrate after long pressing one of them, some callbacks after choosing them, possibility to prepare custom icon's view, page control and horizontal scrolling. I was trying to use OpenSpringBoard but weirdly couldn't see scrollview and pagecontrol working in this project - it seems that there's possibility to use only one page. On the other hand, myLauncher(https://github.com/dlinsin/myLauncher) isn't so easy to include in project, as I need a seperate view with some delegate methods. I need to be compatible with iOS 4.2

  • how to learn ios game development using swift.. good starting point?

    - by hamobi
    I've published a simple app on the app store using objective-c. That was a good learning experience but I never grew to love the language. Later on I jumped into learning cocos2d in order to begin developing a game.. but objective-c always seemed really cumbersome to write. Eventually I put my project aside. Now that swift has come out.. It has made me think about developing games again.. I know that xcode has some project types geared towards game development, but since I'm a beginner in this area I really need some hand holding (books / tutorials) to get started. Cocos2d seems like its really stuck in that objective-c world. What's the best way for a beginner to learn game development using swift?

  • Single IBAction for multiple UIButtons versus single IBAction for single UIButton

    - by Miraaj
    While using story-board there are two different approaches which my team mates follow: Approach 1: To bind unique action with each button, ie: Done button - binded to - doneButtonAction Cancel button - binded to - cancelButtonAction OR Approach 2: To bind single action to multiple buttons, ie: Done button - binded to - commonButtonAction Cancel button - binded to - commonButtonAction Then in commonButtonAction they prefer to use switch case like this: - (IBAction)commonButtonAction:(id)sender { UIButton *button = (UIButton *)sender; switch (button.tag) { case 201: // done button [self doneButtonAction:sender]; break; case 202: // cancel button [self cancelButtonAction:sender]; break; default: break; } } - (void)cancelButtonAction:(id)sender { // no interesting stuff, simple dismiss of view :-( } - (void)doneButtonAction:(id)sender { // some interesting stuff ;-) } Reasoning which they give to follow approach 2 is - in each view controller during code walk through anyone can easily identify where to find code related to button actions. While others discard this idea because they say that adding an extra switch case is unnecessary and is not a common practice. What are your views?

  • Getting rid of Massive View Controller in iOS?

    - by Earl Grey
    I had a discussion with my colleague about the following problem. We have an application where we need filtering functionality. On any main screen within the upper navigation bar, there is a button in the upper right corner. Once you touch that button, an custom written Alert View like view will pop up modally, behind it a semitransparent black overlay view. In that modal view, there is a table view of options, and you can choose one exclusively. Based on your selection, once this modal view is closed, the list of items in the main view is filtered. It is simply a modally presented filter to filter the main table view.This UI design is dictated by the design department, I cannot do anything about it so let accept this as a premise. Also the main filter button in the navbar will change colours to indicate that the filter is active. The question I have is about implementation. I suggested to my colleague that we create a separate XYZFilter class that will be an instance created by the main view controller acquire the filtering options handle saving and restoration of its state - i.e. last filter selected provide its two views - the overlay view and the modal view be the datasource for the table in its modal view. For some unknown reason, my colleague was not impressed by that approach at all. He simply wants to do these functionalities in the main view controller, maybe out of being used to do this in the past like that :-/ Is there any fundamental problem with my approach? I want to keep the view controller small, not to have spaghetti code create a reusable component (for use outside the project) have more object oriented, decoupled approach. prevent duplication of code as we need the filtering in two different places but it looks the same in both.. Any advice?

  • Will Swift or any upcoming Apple developer tools be incompatible with .xibs? [on hold]

    - by user
    I'm still letting the sudden announcement of a language change (Swift) sink in, and I'm wondering if the upcoming platform changes will still be highly compatible with using .xibs for interface development. I've used Storyboards in multiple production projects but I don't feel very productive with them, and I get tired of managing multiple storyboards, links, and xib connections for complex views. I don't see why Swift and Xcode 6 wouldn't cooperate with Xibs indefinitely if it still allows @IBOutlets and @IBActions, but I have realized that Apple purposely shuns old methodologies for the sake of doing so. If there's any reasons to turn away from xibs in iOS8 besides the use-the-new-stuff conventional wisdom, I'd like to know before its too late.

  • Migration of PowerBuilder application to multiplatform

    - by Alex Bibiano
    I developed a client/server application with PowerBuilder in the past for medical clinics and done maintenance for it until now. Now, some clients are asking me to develop a release for Mac/Linux and need some advice about what programming language/technology is best suited for it and the learning curve. It’s not a very very big program but I’m the only developer and have done it in my spare time. PowerBuilder is very productive for this kind of projects (database centric), but it’s not multiplatform and it’s hard to sell PowerBuilder application now days (web, .NET, java sells a lot better with his marketing). My programming skills: - I studied C and C++ in the past (university) but never used it on real projects - Have some Java experience but not in desktop applications - Some experience with Ruby on Rails for web projects - Good skills with PowerBuilder and C# (.NET) (there are my main developing languages) My first dilemma is if I change the desktop application to a web interface, but I think the user will lose some user-experience, and some doctors don’t have a clinic (they are alone at home with my software). I think installing a web application (with webserver) for one user will be overwhelming. If I continue developing desktop application, what is at the moment a good framework/toolset to learn having my skills? Somebody has had similar experiences? A lot of thanks

  • Can someone explain how this IOS Pan Gesture Recognition works? [on hold]

    - by user79894
    It is ios app using Pan Gesture Recognizer It works great, but I didn't get it. I wanna do some changes if the dragged UIView reaches a specific position it would call another method. Any comments are appreciated. - (IBAction)handlePan1:(UIPanGestureRecognizer *)recognizer { CGPoint translation = [recognizer translationInView:self.view]; recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x, recognizer.view.center.y + translation.y); [recognizer setTranslation:CGPointMake(0, 0) inView:self.view]; /* [x1 setText:[NSString stringWithFormat: @"%.2f", recognizer.view.center.x]]; [y1 setText:[NSString stringWithFormat: @"%.2f", recognizer.view.center.y]]; [x2 setText:[NSString stringWithFormat: @"%.2f", translation.x]]; [y2 setText:[NSString stringWithFormat: @"%.2f", translation.y]];*/ }

  • New to iPhone Development - iOS5 Storyboard

    - by Peter
    I'm new here and pretty new to iOS development. My question is basically, should I learn the old school development methods or just learn how to do things using the latest tools (i.e. Storyboard)? I've had a go with the Storyboard feature of XCode 4.2 and it's very powerful. My only concern is that it requires iOS 5. I don't mind learning the old way of doing things but I've been having trouble finding tutorials/examples for XCode 4.2 that don't use the storyboard. An example would be the with my trouble finding a good tutorial on how to embed a Navigation Controller into a TabBarController. A lot of the material out there seems to be for older version of XCode. Using the storyboard I'm able to set this up with seconds but still haven't managed to get it working without it. So in short :) would you guys suggest I continue my project using the Storyboard or make the extra effort to do things a little more manually?

  • How should I expand Jenkins to help me release? [closed]

    - by Amy Worrall
    Pushing new Sparkle releases of our internal apps is a pain. I have to make the build, make the release notes file, sign the .zip with the private key, and add a new entry to the appcast file tying everything together. I'd love it if Jenkins could help: use the commit messages for the release notes, and automatically do the rest of it. Should I be looking at writing a new Jenkins plugin, or using shell scripting, or is there something already that will do what I want? (A quick Google didn't find anything.)

  • (Not So) Silly Objective-C inheritance problem when using property - GCC Bug?

    - by Ben Packard
    Update 2 - Many people are insisting I need to declare an iVar for the property. Some are saying not so, as I am using Modern Runtime (64 bit). I can confirm that I have been successfully using @property without iVars for months now. Therefore, I think the 'correct' answer is an explanation as to why on 64bit I suddenly have to explicitly declare the iVar when (and only when) i'm going to access it from a child class. The only one I've seen so far is a possible GCC bug (thanks Yuji). Not so simple after all... Update - I messed up one line of the original copy and paste - corrected. The @property call was missing (nonatomic, retain) but is a red herring - STILL NEED AN ANSWER! Thanks. I've been scratching my head with this for a couple of hours - I haven't used inheritance much. Here I have set up a simple Test B class that inherits from Test A, where an ivar is declared. But I get the compilation error that the variable is undeclared. This only happens when I add the property and synthesize declarations - works fine without them. TestA Header: #import <Cocoa/Cocoa.h> @interface TestA : NSObject { NSString *testString; } @end TestA Implementation is empty: #import "TestA.h" @implementation TestA @end TestB Header: #import <Cocoa/Cocoa.h> #import "TestA.h" @interface TestB : TestA { } @property (nonatomic, retain) NSString *testProp; @end TestB Implementation (Error - 'testString' is undeclared) #import "TestB.h" @implementation TestB @synthesize testProp; - (void)testing{ NSLog(@"test ivar is %@", testString); } @end

  • Lotus Domino Administrator client missing

    - by vit
    Hi, I have just installed the trial version of Lotus Domino and now I'm pulling my hair out as for some stupid reason I can't find the Domino Administrator client. I have found multiple suggestions on various websites where to download it from, but all of them lead to the same section of the IBM website which actually only has the Lotus Notes client, despite the page title. What am I missing here and where do I find the client? Thank you.

  • PowerShell: New-PSDrive error handling

    - by mazebuhu
    Hello, I have a script where I mount with the command "New-PSDrive" a network drive. Now, since the script is running as a "cronjob" on a server I want to have some error detection. If for any reason the command New-PSDrive fails the script should stop executing and notify that something went wrong. I have the following code: Try { New-PSDrive -Name A -PSProvider FileSystem -Root \\server\share } Catch { ... handle error case ... } ... other code ... For testing reasons I specified a wrong server name and I get the following error "New-PSDrive : Drive root "\wrongserver\share" does not exist or it's not a folder". Which is OK since the server does not exists. But the script does not go into the Catch clause and stop. It happily continues to run and ends up in a mess since no drive is mounted :-) So my question, why? Is there any difference in Exception handling in PowerShell? I should also note that I'm a noob in PowerShell scripting. Bye, Martin

  • OpenVZ multiple networks on CTs

    - by picca
    I have Hardware Node (HN) which has 2 physical interfaces (eth0, eth1). I'm playing with OpenVZ and want to let my containers (CTs) have access to both of those interfaces. I'm using basic configuration - venet. CTs are fine to access eth0 (public interface). But I can't get CTs to get access to eth1 (private network). I tried: # on HN vzctl set 101 --ipadd 192.168.1.101 --save vzctl enter 101 ping 192.168.1.2 # no response here ifconfig # on CT returns lo (127.0.0.1), venet0 (127.0.0.1), venet0:0 (95.168.xxx.xxx), venet0:1 (192.168.1.101) I believe that the main problem is that all packets flows through eth0 on HN (figured out using tcpdump). So the problem might be in routes on HN. Or is my logic here all wrong? I just need access to both interfaces (networks) on HN from CTs. Nothing complicated.

  • adding or routing additional domain email addresses

    - by Mustafa Ismail Mustafa
    We have exchange 2007 and we bought a new domain name and we're still keeping the old one so that we can wean everyone off of the old emails. Now, I'm wondering how to go about this. I need to add the new domain as accepted and authoritative by the exchange server. Emails on the new domain need to get routed to the inbox and ditto the old emails, however, I want to be able to change the reply-to in the header to the new email address automatically. I also want to set the new email addresses as the defaults. Ideally, I'd like to be able to add a message at the bottom of every externally outgoing email saying that the new email is [email protected]. But this is a nice to have, certainly not a must have. I've added the new domain as authoritative, and managed to change the primary smtp email addresses to the new one, but sent emails are not being routed to them and neither are the old email addresses! Now how the heck would I go about fixing all of that? I'm completely stumped! TIA

  • IP-dependent local port-forwarding on Linux

    - by chronos
    I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

  • how to go about scaling a web-application ?

    - by phoenix24
    for someone whoes been primarily a web-application developer, and know not much about scaling/scalability techniques. I'll start by stating my application is written in Python, using Django; a fairly standard setup. I currently use Apache 2.2 for my webserver, and MySql for my database server; both running on the same vps server. Up until now, it was basically a prototype and merely 15-30 concurrent users at any given time; so I had no issues, but now since we'll be adding more users we'll have severe performance issues. So my question is how do i go about scaling my web-application? and my plan is as follows. Now I have just one vps server running, apache + mysql. Next, I plan to add another vps server, to run only MySql; so i'll have one web-server and one db server. Next, I'll add Memcache to the webserver for caching data; and taking some load off mysql. Next, another web-server for serving all the static content; Next, a vps server for load-balancing (nginx/varnish) behind which would be my two web-servers and then db-server. Does that sound like a workable strategy, please guide me around here.

  • Linux file server for an inexperienced admin

    - by Pat
    A charity I volunteer for wants a file server for their mostly Windows machines (about five XP and 7 machines, with some Mac laptops every now and then). For the server, I have a PC with an Intel Core 2 Duo 3GHz proc, 4GB of DDR2 400MHz RAM, and a 500 GB HDD. (I should point out that they do not currently have any server - they are just using Windows to share a folder on one of the PCs.) What is a linux distro that is easy to configure for Windows file serving yet stable and secure enough to protect sensitive data without an expert sysadmin? I'm guessing that a Debian distro would probably fit the security bill, but I don't know of any tailored to novice sysadmins. Also, are there any killer apps for making this easy to administer and set up (as a Windows file server, in particular - this answer is a good example)? Would FreeNAS be sufficient? Once it's all set up, what are the minimum measures I need to take to keep the data secure? I found this somewhat helpful answer, but it's not specific to my question of just getting a secure file server up, running, and maintained.

  • Database for heat tolerances of various cables?

    - by I. F.
    Is there any kind of unified database of heat tolerances for networking cables? I've been setting up a number of home/small office networks lately and as a mostly-amateur I could really use some information on what is safe to run behind a radiator, next to a steam pipe, etc. The question I'm up against at the moment is: Can I run normal RJ11 phone line cable (from DSL modem to phone jack) behind a steam radiator without risking a fire? Unlike cat5, I could not find published standards for these, so I'm turning to experts with more experience. This is a cut-rate show. Do I go out and buy more cabling, and if so which, or use the spare that I have?

  • Registering VPS server: some newbie questions [closed]

    - by Angstrem
    I'm new to VPS in particularly and to servers in general. But it turns out that I need to raise and maintain a VPS server. I've decided to register it at https://nodedeploy.com/ but I have lot's of questions, conducted with it. Does that site provide VPS hosting or it is just a web-site hosting? Will the payments for the VPS be done automatically, or I'll have to do them manually? How do I select a VPS OS that will be installed? How do I get the root password? Will it be available after payment? Is ssh access supported there? How can I cancel my account if something goes wrong with my project? What VPS-hosting service would you recommend for using? Maybe, the questions are really full and newbie, but It's really important for me to know that points. I'll be very grateful for any answers.
