  • How to better integrate a unix development environment into Windows

    - by SKenz
    I'm mostly a Windows user but I do most of my development (essentially web development) using unix tools and software. I've been going back and forth between using a dedicated lubuntu virtual machine on Virtualbox and using some tools directly in windows (msgit, python, django), but none of these approaches is entirely satisfactory. I'd like to hear of ways other devs use to better integrate a unix workflow into windows. For instance tighter integration between a linux and vm and windows. The vagrant demo showed how a VM could work off of a windows project folder and I found that nice. I'd like to hear of other tools and tips that would help mimic the workflow one can find on OS X (of course I understand that it cannot be as tightly integrated on Windows as it doesn't have the same unix underpinnings). PS: I have tried cygwin as well EDIT for clarifications about What I find lacking (thanks to axblount for pointing that out) : unix tools like msys et al do not work as well as their native unic counterparts. Many scripts, installers require further configuration or do not work at all. For instance getting virtualenvwrapper to work is not very straightforward. virtualbox: ideally I would like to use windows software (photoshop, sublime text 2) seamlessly with linux. I mostly use a FTP client atm to move over files edited on the windows side which is a tedious process.

  • cocoa - converting a double to string

    - by Mike
    I have a double number and I would like to convert it to string. The number is, for example, something like 24.043333332154465777... but if I convert it to string using something like NSString *myString = [NSString stringWithFormat:@"%f", myDouble]; The string is just 24.043333 how do I get a full string the corresponds to the whole double number? What other methods do I have to convert this?

  • CAScrollLayer doesn't scroll!

    - by Cliff
    Maybe it's because it's late. Whatever the reason I can't figure out why I'm having trouble with a simple CSScrollLayer example I'm trying. I add a 50 pixel Eclipse icon to a view based project and in my initialize method (called from initWithNibName:bundle:) I have this: -(void) initialize { CAScrollLayer *scrollLayer = [CAScrollLayer layer]; scrollLayer.backgroundColor = [[UIColor blackColor] CGColor]; CGRect bounds = self.view.bounds; scrollLayer.bounds = CGRectMake(0, 0, bounds.size.width, bounds.size.height); scrollLayer.contentsRect = CGRectMake(0, 0, bounds.size.width + 800, bounds.size.height + 800); scrollLayer.borderWidth = 2.5; scrollLayer.borderColor = [[UIColor redColor] CGColor]; scrollLayer.position = CGPointMake(self.view.center.x, self.view.center.y - 20); scrollLayer.scrollMode = kCAScrollBoth; [self.view.layer addSublayer:scrollLayer]; UIImage *image = [UIImage imageNamed:@"eclipse32.gif"]; for(int i=0; i<6; i++) { layer = [CALayer layer]; layer.backgroundColor = [[UIColor blackColor] CGColor]; layer.bounds = CGRectMake(0, 0, 100, 100); layer.contents = (id)[image CGImage]; layer.position = CGPointMake(layer.bounds.size.width * i, self.view.center.y); [scrollLayer addSublayer:layer]; } // [button removeFromSuperview]; // [self.view addSubview:button]; // self.view.userInteractionEnabled = YES; [image release]; } The scroll layer shows, the icon is repeated on the layer I have a border around the edge of the screen. Everything is lovely except I can't scroll the icons. I've tried with/without setting scroll mode. I've tried with a single stretched icon that falls off screen. I've tried everything. What am I doing wrong?

  • Cannot hide a UIButton - Please help!

    - by Neurofluxation
    Hey again, I have the following code: visitSite.hidden = YES; For some reason, when I click a UIButton and call this piece of code, the visitSite button does not hide. The code is within this block: -(IBAction)welcomeButtonPressed:(id)sender { [UIButton beginAnimations:@"welcomeAnimation" context:NULL]; [UIButton setAnimationDuration:1.5]; [UIButton SetAnimationDidStopSelector:@selector(nowHideThisSiteButton:finished:context:)]; [UIButton setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; ((UIView *)sender).hidden = YES; [UIButton commitAnimations]; } and the stop selector below: -(void)nowHideThisSiteButton:(NSString *)animationID finished:(BOOL *)finished context:(void *)context { visitSite.hidden = YES; } I've also tried [visitSite setHidden:YES]; and that fails as well. ALSO I've noticed that the setAnimationDidStopSelector does not get called at all. Also, visitSite (when NSLogged) equals: <UIButton: 0x1290f0; frame = (0 0; 320 460); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x1290f0>> visitSite.hidden (when NSLogged) equals: NULL Any more ideas? :(

  • UIPickerView not displaying

    - by 4thSpace
    I have a UIPickerView on a UIView. I've implemented its protocol and delegates in the .m file: <UIPickerViewDataSource, UIPickerViewDelegate> In IB, I've connected the above to the picker, which I also have an IBoutlet for. The methods look like this: - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView { return 1; } - (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component { return [self.arr count]; } - (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { return @"test"; } - (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { //do something } Any ideas which piece I'm missing to get the picker working?

  • Should Professional Development occur on company time?

    - by jshu
    As a first-time part-time software developer at a small consulting company, I'm struggling to organise time to further my own software development knowledge - whether that's reading a book, keeping up with the popular questions on StackOverflow, researching a technology we're using in-depth, or following the front page of Hacker News. I can see results borne from my self-allocated study time, but listing and demonstrating the skills and knowledge gained through Professional Development is difficult. The company does not have any defined PD policy, and there's a lot of pressure to get something deliverable done now! when working for consultants. I've checked what my coworkers do, and they don't appear to allocate any time to self-improvement; they just work at the problems they're given, looking up specific MSDN references, code samples, and the like as they need them. I realise that PD policy is going to vary across companies of different size and culture, and a company like my own is probably a bit of an edge case. I'd love to hear views and experiences from more seasoned developers; especially those who have to make the PD policy choices in their team or company. I'd also like to learn about the more radical approaches to PD, even if they're completely out there; it's always interesting to see what other people are trying. Not quite a summary, but what I'm trying to ask: Is it common or recommended for companies to allocate PD time? Whose responsibility is it to ensure a developer's knowledge and skills are up to date? Should a part-time work schedule inspire a lower ratio of PD time : work? How can a developer show non-developer coworkers that reading blogs and books is net productive? Is reading blogs and books actually net productive? (references welcomed) Is writing blogs effective as a way of PD? (a recent theme on Hacker News) This is sort of a broad question because I don't know exactly which questions I need to ask here, so any thoughts on relevant issues I haven't addressed are very welcome.

  • forwarding a notification to another class

    - by Mike
    I am using this method - (void)keyboardWillShow:(NSNotification *)notification that is triggered when the keyboard shows. When this method is triggered, it receives a notification that contains several parameters about the keyboard, as the animation duration, animation curve and frame. I need to forward this notification and all its parameters to another class. So, I've tried to do this inside keyboardWillShow: [[NSNotificationCenter defaultCenter] postNotificationName:@"doSomething" object:notification userInfo:nil]; the doSomething notification runs doSomething method on another class, and it has this form: - (void) doSomething:(NSNotification *)notification { but when I try to read the notification values on this other class, using, for example, myRect = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; I obtain zero for all values. The notification is losing its parameters and not being forwarded. How can I do that? thanks.

  • Save downloaded content when in app purchase is complete

    - by jakob
    Hello experts! I have created an app which allows users to buy non-consumable content. The retrieving-ids-payment-process works like a charm. What i can't really figure out is how my content should be saved into the phone. The existing structure is that I have all my current content in Resources/packages/. For every package there is an matching entry in a package.plist. When the purchase is complete it is time to download the content from the server. What i retrieve from the server is a zip file with the new package that I have bought. My observer will call a method named provideContent: -(void) provideContent: (NSString*) productIdentifier { In here I will call my server and download the package } What i need from you guys is some sort of step by step walkthrough or tutorial of how, when the zip is retrieved(is zip allowed?), unpack this zip and add it to my current package structure. Thank you in advance

  • Where can I find a list of pushViewController transitions?

    - by barfoon
    Hey everyone, Where can I find a list of transitions for bringing a new Viewcontroller onto the stack. My line of code is: [peoplePicker pushViewController:myDetail transition:6]; after selecting a contact. Where can I find a list of transitions, and why does "6" work correctly? Also I get a warning with this code saying it may not respond to transition, even though it produces the transition correctly. What is the proper way to do these animations? Thanks,

  • How to get a UIScrollView embedded within a UITableCellView to scroll?

    - by Zan
    I have a scroll view containing several images embedded within a custom cell view, it sometimes scrolls horizontally if I keep holding the cell for a while. I tried a lot of things and it doesn't seem to work, please help? Here's part of the CustomCell : UITableViewCell code: -(void) layoutSubviews { CGRect scrollViewFrame = CGRectMake(0, 0, 320, 200); self.scrollView.frame = scrollViewFrame; self.scrollView.backgroundColor = [UIColor whiteColor]; self.scrollView.contentSize = CGSizeMake((320*3), 200); self.scrollView.scrollEnabled = YES; self.scrollView.clipsToBounds = YES; self.scrollView.pagingEnabled = YES; self.scrollView.showsHorizontalScrollIndicator = NO; self.scrollView.showsVerticalScrollIndicator = NO; self.scrollView.scrollsToTop = NO; self.scrollView.delegate = self; self.scrollView.userInteractionEnabled = YES; // add 3 images to subview here pageControl.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.7]; pageControl.frame = CGRectMake(0, 170, 320, 30); pageControl.numberOfPages = 8;} I tested the code on a UIViewController and it works just fine, I'm guessing that this is caused by cell selection and I tried returning nil when the cell gets selected and that didn't work. I also tried passing touches to the scrollview and that didn't work either, please help?

  • Adding More Than 2 Delegates in iPhone App

    - by golfromeo
    This is a simple question that can be answered fast by someone who's more familiar with Objective-C than I am- how can one add more than 2 delegates to a Class? To clarify, I'm used to putting delegates in classes like this: @interface ViewController : UIViewController <UIWebViewDelegate> { ... When I try to put two delegates: @interface ViewController : UIViewController <UIWebViewDelegate> <UITextFieldDelegate> { ... ...the app gives many errors, none of which help with the situation. Is there a separator that I need to put between the delegates, or is it possible at all to have more than two? Thanks for any help in advance.

  • Need Help With Simple Counting Bug in iPhone SDK

    - by seanny94
    So I'm basically making an app that adds a count to a number and then displays it each time you tap the button. However, the first tap issued doesn't take any action but adds one (just as planned) on the second tap. I've searched to the ends of the earth looking for the solution with no luck, so I'll see what you guys can make of this. :) #import "MainView.h" @implementation MainView int count = 0; -(void)awakeFromNib { counter.text = @"0"; } - (IBAction)addUnit { if(count >= 999) return; NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count++]; counter.text = numValue; [numValue release]; } - (IBAction)subtractUnit { if(count <= 0) return; NSString *numValue = [[NSString alloc] initWithFormat:@"%d", count--]; counter.text = numValue; [numValue release]; } @end

  • A view "transparent" to touches in some areas

    - by Mike
    I have this transparent view that covers the whole screen. I using this view to group objects because I need to run them together around a specific anchor point. Lets call this view transparentView. At some point, transparentView contains two subviews. Two vertical bars full of icons, one on the left and one on the right of the screen. I need these bars and their icons to respond to touches, so I have to set transparentView setUserInteraction to YES. The area between the two vertical bars are totally transparent. transparentView is on top of other views and I need these other views to respond to taps but, the transparent area of transparentView are intercepting the taps and not letting them go thru to the view below. This transparent view is a UIImageView based class. I have tried to forward taps on that class, using - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [self.nextResponder touchesBegan: touches withEvent:event]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self.nextResponder touchesMoved: touches withEvent:event]; } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [self.nextResponder touchesEnded: touches withEvent:event]; } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesEnded:touches withEvent:event]; } but this is not working. How can I do that? thanks.

  • Distributed Development Tools -- (Version control and Project Management)

    - by Macy Abbey
    I've recently become responsible for choosing which source control and project management software to use for a company that employs me. Currently it uses Jira (project management) and Subversion (version control). I know there are many other options out there -- the ones I know about are all in this article http://mashable.com/2010/07/14/distributed-developer-teams/ . I'm leaning towards recommending they just stay with what they have as it seems workable and any change would have to be worth the cost of switching to say github/basecamp or some other solution. Some details on the team: It's a distributed development shop. Meetings of the whole team in one room are rare. It's currently a very small development team (three developers). The project management software is used by developers and a product manager or two. What are you experiences with version control and project management web applications? Are there any you would recommend and you think are worth the switching cost of time to learn new services / implementing the change? Edit: After educating myself further on the options it appears DVCS offer powerful benefits that may be worth investing in now as opposed to later in the company's lifetime when the switching cost is higher: I'm a Subversion geek, why I should consider or not consider Mercurial or Git or any other DVCS?

  • UIImageWriteToSavedPhotosAlbum showing memory leak with iPhone connected to Instruments

    - by user168739
    Hi, I'm using version 3.0.1 of the SDK. With the iPhone connected to Instruments I'm getting a memory leak when I call UIImageWriteToSavedPhotosAlbum. Below is my code: NSString *gnTmpStr = [NSString stringWithFormat:@"%d", count]; UIImage *ganTmpImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:gnTmpStr ofType:@"jpg"]]; // Request to save the image to camera roll UIImageWriteToSavedPhotosAlbum(ganTmpImage, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil); and the selector method - (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { NSString *message; NSString *title; if (!error) { title = @"Wallpaper"; message = @"Wallpaper Saved"; } else { title = @"Error"; message = [error description]; } UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; } Am I forgetting to release something once the image has been saved and the selector method imageSavedToPhotosAlbum is called? Or is there a possible known issue with UIImageWriteToSavedPhotosAlbum?

  • How would one use Cocos2d to create a game like this.

    - by John Stewart
    http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&ign-mpt=uo%3D6 So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is not going to be a market release game. This is totally going to be learning purposes only. So to start off my question is: Would something like this be achievable using Cocos2d? How would I go about building the physics for this? How can one do a screen scroll like the way they do in cocos2d? (any example code would be great) This is just to start off. If you have any particular questions please do add to this question.

  • While submitting app to iOS App Store, "Unable to unzip application"

    - by Ivan Vucica
    I've successfully submitted "Product Name" to App Store. However, submitting "Product Name Lite", I keep getting the error "Unable to unzip application" in both Application Loader and built-in Xcode's uploader. Error persists even after eliminating spaces from the product name; in fact, I don't think there's whitespace anywhere in the app or the plist anymore. What might be causing this "highly descriptive" error? I'm using Xcode 3.2.5. Attempting to clean, build, and build&archive did not help.

  • cocoa - IF failing for double?

    I have a set of NSTimeIntervals like this: NSArray *mySet = [NSArray arrayWithObjects: [NSNumber numberWithDouble: time1], // [NSNumber numberWithDouble: time2], [NSNumber numberWithDouble: time3], nil]; // suppose that at this time // time1 = 0.00000 // time2 = 18.3200 // time3 = 21.6500 at some point in my code I want to test if currentTime is greater or equal to one of the times on the array, so I do // currentTime = 18.32 right now for (int i=0; i<[mySet count]; i++) { if (currentTime >= [[mySet objectAtIndex:i] doubleValue]) { NSLog(@"%d...", i); } } The output should be "1...2..." but the output is just "1..." when i = 1, it is comparing 18.32 to 18.32 and failing to recognize that the value is equal or greater than the other? WTF??? How can that be? thanks for any help.

  • Subclassing NSObject, can it cause problems?

    - by Sheehan Alam
    I have a very basic data class that is subclassed from NSObject. I declare a few strings, make sure they have properties (nonatomic, copy), and synthesize them. The only method I implemented was dealloc() which releases my strings. Can any memory problems arise from just this? Are there any other methods I need to implement?
