• How to execute statements in order in objective c

  - by Vu Tu?n Anh

  When i tap on my button, my function was called [myBtn addTarget:self action:@selector(myFunction) forControlEvents:UIControlEventTouchUpInside]; In my function, a collection of complex statement will be executed and take a litte bit time to run, so i want to show Loading (UIActivityIndicatorView) as the following: -(void) addTradeAction { //Show Loading [SharedAppDelegate showLoading]; //disable user interaction self.view.userInteractionEnabled = NO; //execute call webservice in here - may be take 10s //Hide Loading [ShareAppDelegate hideLoading]; } When tap on myBtn (my Button) - after 3s or 4s, [ShareAppDelegate showLoading] was called. It is unusual when i use [ShareAppDelegate showLoading] on other Function, - it work very nice, i mean all the statement be executed in order. All i want, when i tap on My Button, Loading will be called immediatelly. Tks in advance

• Maven Java Source Code Generation for Hibernate

  - by Adam

  Hi, I´m busy converting an existing project from an Ant build to one using Maven. Part of this build includes using the hibernate hbm2java tool to convert a collection of .hbm.xml files into Java. Here's a snippet of the Ant script used to do this: <target name="dbcodegen" depends="cleangen" description="Generate Java source from Hibernate XML"> <hibernatetool destdir="${src.generated}"> <configuration> <fileset dir="${src.config}"> <include name="**/*.hbm.xml"/> </fileset> </configuration> <hbm2java jdk5="true"/> </hibernatetool> </target> I've had a look around on the internet and some people seem to do this (I think) using Ant within Maven and others with the Maven plugin. I'd prefer to avoid mixing Ant and Maven. Can anyone suggest a way to do this so that all of the .hbm.xml files are picked up and the code generation takes place as part of the Maven code generation build phase? Thanks! Adam.

• Resizing Tab Bar Controller Views (iPhone dev)

  - by damiandawber

  Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

• Twisted chainDeferred not working as expected

  - by Martin Gergov

  I have a problem figuring out a somewhat simple twisted python code. From what I have red in the docs, the code here should work without Unhandled Error. I get this: HELLO! HANDLED! HANDLED 2! Unhandled error in Deferred: Unhandled Error Traceback (most recent call last): File "package_tester.py", line 31, in <module> a().callback(2) File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 368, in callback self._startRunCallbacks(result) File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 464, in _startRunCallbacks self._runCallbacks() --- <exception caught here> --- File "/usr/local/lib/python2.7/dist-packages/twisted/internet/defer.py", line 551, in _runCallbacks current.result = callback(current.result, *args, **kw) File "package_tester.py", line 5, in c raise Exception() exceptions.Exception: Isn't the failure from the chained deferred passed to end() errback ?

• Remove a toolbar when pushing a new view

  - by nevan

  In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar. I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left. Using [self.navigationController setToolbarHidden:YES] in viewDidLoad:animated also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space). I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible). How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

• SQL UNION ALL with a INNER JOIN

  - by kOhm

  I'm looking for the best way to display all rows from two tables while joining first by one field (dwg) then where applicable a 2nd join on part. Table1 data consists of schematics(dwg) along with a list of parts required to build the item depicted in the drawing. Table2 consists of data about the actual parts ordered to build the schematic. Some parts in table2 are a combination of parts in table1 (ex: foo and bar in table1 were ordered as foobar in table2). I can display all rows in both tables with UNION ALL, but this doesn't join on both the dwg and part fields. I looked at FULL OUTER JOIN also, but I haven't figured out how to join first by dwg, then by part. Here is an example of the data. table1 table2 dwg part qty order dwg part qty ----- ----- ----- ----- ----- ----- ----- 123 foo 1 ord1 123 foobar 1 123 bar 1 ord1 123 bracket 2 123 widget 2 ord2 123 screw 4 123 bracket 4 ord2 123 nut 4 456 foo 1 ord2 123 widget 2 ord2 123 bracket 2 ord3 456 foo 1 Desired output: The goal is to create a view that provides visibility to all parts in table1 and the associated orders in table2 (including those parts that appear in one but not the other table) so that I can see all the drawing parts in table1 and the associated records in table2 along with records in table2 where the part wasn't in table1. part_request_order_report dwg part qty order part qty ----- ----- ----- ------ ----- ----- 123 foo 1 123 bar 1 123 widget 2 ord2 widget 2 123 bracket 4 ord1 bracket 2 123 bracket 4 ord2 bracket 2 123 ord1 foobar 1 123 ord1 screw 4 123 ord1 nut 4 456 foo 1 ord3 foo 1 Is this possible? Or am I better off iterating through the data to build the report table? Thanks in advance.

• iphone instance / class method issue

  - by user290031

  Hey All, Okay, so I have a viewController method that has some elements created with interface builder and some I coded myself. I created a view in the IB...lets call it viewOne. I created a loop that creates buttons (through code) and places them on a separate view (viewTwo). This is done in a class method. However, I want the view I made to be opened everytime one of the buttons is clicked. So I did: [button addTarget:self action:@selector(woogoo:) forControlEvents:UIControlEventTouchUpInside]; The woogoo class does the following: +(void) woogoo:(id)sender { //back button [self.view addSubview:viewOne] } However, the program crashes when a button is clicked. I did try making woogoo an instance method but it also crashes in this case too. All I want to do is show viewOne when a button is clicked. Any ideas what I can do?

• Quering distinct values throught related model

  - by matheus.emm

  Hi! I have a simple one-to-many (models.ForeignKey) relationship between two of my model classes: class TeacherAssignment(models.Model): # ... some fields year = models.CharField(max_length=4) class LessonPlan(models.Model): teacher_assignment = models.ForeignKey(TeacherAssignment) # ... other fields I'd like to query my database to get the set of distinct years of TeacherAssignments related to at least one LessonPlan. I'm able to get this set using Django query API if I ignore the relation to LessonPlan: class TeacherAssignment(models.Model): # ... model's fields def get_years(self): year_values = self.objects.all().values_list('year').distinct().order_by('-year') return [yv[0] for yv in year_values if len(yv[0]) == 4] Unfortunately I don't know how to express the condition that the TeacherAssignment must be related to at least one LessonPlan. Any ideas how I'd be able to write the query? Thanks in advance.

• Why is my UIViewController initializer never called?

  - by mystify

  I made a view-based project from a fresh template. There's a UIViewController which is created with an XIB. In the implementation I uncommented that and added an NSLog. But this is never called: // The designated initializer. Override to perform setup that is required before the view is loaded. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) { // Custom initialization NSLog(@"nib"); } return self; } since that is initialized from a nib / xib, that should be called for sure, right? however, it doesn't. I do get an NSLog message when I put that in viewDidLoad.

• Needed environment for building gstreamer plugins in Windows

  - by utnapistim

  Hi, I've been strugling for two weeks to create an environment for building a gstreamer plugin on windows (needed for a songbird addon). I've installed MSYS, MinGW and Cygwin, then installed GStreamer OSSBuild, and I also downloaded the sources for Songbird, which come with their own precompiled version of gstreamer. I was unable to run gst-inspect (or any other gstreamer applications) from the songbird sources and I figured I will settle for OSSBuild. When following the instructions for building a GST plugin (found here) through, cygwin will not recognize the OSSBuild and the build fails when running autogen, with the following error: checking for GST... no configure: error: You need to install or upgrade the GStreamer development packages on your system. On debian-based systems these are libgstreamer0.10-dev and libgstreamer-plugins-base0.10-dev. on RPM-based systems gstreamer0.10-devel, libgstreamer0.10-devel or similar. The minimum version required is 0.10.16. configure failed I could also not use MSYS or MinGW as they are unable to run autogen at all. I understand that cygwin should have it's own gstreamer development packages but I couldn't find how to install them. My question: How do I install the gstreamer packages in cygwin or how do I build using cygwin with the OSSBuild dependencies? In short, how do I get an environment where I can build a gstreamer plugin under windows?

• Updating DetailViewController from RootController

  - by Stefano Salmaso

  I'm trying to create an iPad application with a similar user interface to Apple's Mail application, i.e: RootView controller (table view) on the left hand side of the split view for navigation with a multiple view hierarchy. When a table cell is selected a new table view is pushed on the left hand side The new view on the left side can update the detail view. I can accomplish both tasks BUT NOT TOGETHER. I mean I can make a multi-level table view in the RootController.(HERE you can find the working source code). Or I can make a single-level table view in the RootController which can update the detailViewController (here there is the source code:http://www.megaupload.com/?d=D6L0463G). Can anyone tell me how to make a multi-level table in the RootController which can update a detailViewController? There is more source code at the link but below is the method in which I presume I have to declare a new detailViewController (which has to be put in the UISplitViewController): - (void)tableView:(UITableView *)TableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; // if([Children count] == 0) { /* Create and configure a new detail view controller appropriate for the selection. */ NSUInteger row = indexPath.row; UIViewController <SubstitutableDetailViewController> *detailViewController = nil; if (row == 0) { FirstDetailViewController *newDetailViewController = [[FirstDetailViewController alloc]initWithNibName:@"FirstDetailView" bundle:nil]; detailViewController = newDetailViewController; } if (row == 1) { SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc]initWithNibName:@"SecondDetailView" bundle:nil]; detailViewController = newDetailViewController; } // Update the split view controller's view controllers array. NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil]; splitViewController.viewControllers = viewControllers//nothing happens..... [viewControllers release];// } else { //Prepare to tableview. RootViewController *rvController = [[RootViewController alloc]initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.current_level += 1; //Set the title; rvController.current_title = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController.tableView reloadData]; //without this instrucion,items won't be loaded inside the second level of the table [rvController release]; } }

• Python module seeing a full list as empty in another module

  - by Nick

  I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

• NSAutoreleasePool carrying across methods?

  - by Tim

  I'm building an iPhone application where I detach some threads to do long-running work in the background so as not to hang the UI. I understand that threads need NSAutoreleasePool instances for memory management. What I'm not sure about is if the threaded method calls another method - does that method also need an NSAutoreleasePool? Example code: - (void)primaryMethod { [self performSelectorInBackground:@selector(threadedMethod) withObject:nil]; } - (void)threadedMethod { NSAutoreleasePool *aPool = [[NSAutoreleasePool alloc] init]; // Some code here [self anotherMethod]; // Maybe more code here [aPool drain]; } - (void)anotherMethod { // More code here } The reason I ask is I'm receiving errors that objects are being autoreleased with no pool in place, and are "just leaking." I've seen other questions where people didn't have autorelease pools in place at all, and I understand why an autorelease pool is needed. I'm specifically interested in finding out whether an autorelease pool created in (in this example) threadedMethod applies to objects created in anotherMethod.

• iPhone check for a constant at runtime in universal app

  - by joshue

  I'm making a universal iPad/iPhone app which can use the iPad's VGA out connector to mirror the content of the app on an external screen. However, the iPhone does not have this functionality. given the following code, [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidDisconnectNotification object:nil]; I get this error on the phone at launch (works fine in ipad) "dyld: Symbol not found: _UIScreenDidConnectNotification" presumably because UIScreenDidConnectNotification doesnt' exist yet in 3.13. How do I check for this at runtime?

• Is there a recommended command for "hg bisect --command"?

  - by blokeley

  I have an emergent bug that I've got to track down tomorrow. I know a previous hg revision which was good so I'm thinking about using hg bisect. However, I'm on Windows and don't want to get into DOS scripting. Ideally, I'd be able to write a Python unit test and have hg bisect use that. This is my first attempt. bisector.py #!/usr/bin/env python import sys import unittest class TestCase(unittest.TestCase): def test(self): #raise Exception('Exception for testing.') #self.fail("Failure for testing.") pass def main(): suite = unittest.defaultTestLoader.loadTestsFromTestCase(TestCase) result = unittest.TestResult() suite.run(result) if result.errors: # Skip the revision return 125 if result.wasSuccessful(): return 0 else: return 1 if '__main__' == __name__: sys.exit(main()) Perhaps I could then run: hg bisect --reset hg bisect --bad hg bisect --good -r 1 hg bisect --command=bisector.py Is there a better way of doing it? Thanks for any advice.

• Cheap windows driver signing for 64 bit Windows 7

  - by kayahr

  I need to install the libusb-win32 driver on Windows 7 64 bit machines. This driver is open source so it is not digitally signed so I want to do this my self but I wonder if this can be done WITHOUT paying lot of money. Is it possible to use a certificate which is NOT signed by Verisign or GlobalSign? Maybe self-signed or by using StartSSL instead? And if yes, how do I do it? According to this howto I have to use a "cross-certificate" (And there are only six available on the Microsoft list and most of them are for CAs which are no longer active) I don't care if the user is confronted with a warning message. I can even accept if the user has to install a special CA certificate first. I only require that the driver runs without manually disabling the signature check on each windows startup.

• Project management and bundling dependencies

  - by Joshua

  I've been looking for ways to learn about the right way to manage a software project, and I've stumbled upon the following blog post. I've learned some of the things mentioned the hard way, others make sense, and yet others are still unclear to me. To sum up, the author lists a bunch of features of a project and how much those features contribute to a project's 'suckiness' for a lack of a better term. You can find the full article here: http://spot.livejournal.com/308370.html In particular, I don't understand the author's stance on bundling dependencies with your project. These are: == Bundling == Your source only comes with other code projects that it depends on [ +20 points of FAIL ] Why is this a problem, (especially given the last point)? If your source code cannot be built without first building the bundled code bits [ +10 points of FAIL ] Doesn't this necessarily have to be the case for software built against 3rd party libs? Your code needs that other code to be compiled into its library before the linker can work? If you have modified those other bundled code bits [ +40 points of FAIL ] If this is necessary for your project, then it naturally follows that you've bundled said code with yours. If you want to customize a build of some lib,say WxWidgets, you'll have to edit that projects build scripts to bulid the library that you want. Subsequently, you'll have to publish those changes to people who wish to build your code, so why not use a high level make script with the params already written in, and distribute that? Furthermore, (especially in a windows env) if your code base is dependent on a particular version of a lib (that you also need to custom compile for your project) wouldn't it be easier to give the user the code yourself (because in this case, it is unlikely that the user will already have the correct version installed)? So how would you respond to these comments, and what points may I be failing to take into consideration? Would you agree or disagree with the author's take (or mine), and why?

• iPhone: Add background button to view when UITableView has no cells

  - by Nic Hubbard

  I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, "No records have been added, Tap to add one", then they click and we create a new one. I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using: if ([[fetchedResultsController sections] count] == 0) { self.tableView.hidden = YES; // Create button w/ image UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(0, 0, 100, 50); [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal]; [self.view addSubview:btn]; } Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white...

• converting NSTimer running not on main runloop to GCD

  - by Justin Galzic

  I have a task that runs periodically and it was originally designed to run on a separate run loop than the main runloop using NSThread and NSTimer. What's the best way to adapt this to take advantage of GCD? Current code: -(void)initiateSomeTask { [NSThread detachNewThreadSelector:@selector(startTimerTask) toTarget:self withObject:nil]; } -(void)startTimerTask { // We won't get back the main runloop since we're on a new thread NSRunLoop *myRunLoop = [NSRunLoop currentRunLoop]; NSPort *myPort = [NSMachPort port]; [myRunLoop addPort:myPort forMode:NSDefaultRunLoopMode]; NSTimer *myTimer = [NSTimer timerWithTimeInterval:10 /* seconds */ target:self selector:@selector(doMyTaskMethod) userInfo:nil repeats:YES]; [myRunLoop addTimer:myTimer forMode:NSRunLoopCommonModes]; [myRunLoop run]; } Is there anything I can do besides replace detachNewThreadSelector with dispatch_async?

• A Newbie question regarding Software Development

  - by Sharif

  Hi, I'm going to complete my B.pharm (Hons.) degree and, you know, I don't have much knowledge about programing. I was wondering to build a software on my own. Could you guys tell me what to learn first for that? Is it too hard for a student of other discipline to build a software? Let me know please. The software I want to make is like a dictionary (or more specifically like "Physician's Desk Reference"). It should find the generic name, company name, indication, price etc. of a drug when I enter the brand name and vice versa. To build a software like that what programing language could help me most and what (and how many) language should I learn first? In my country, there is no practice of Community pharmacy (most of the pharmacy stores are run by unskilled people), that's why this type of thing could help them sell drugs. Would you please tell me what I'm to do and how tough it is? I'm very keen to learn programming. Thanks in advance NB: I started this post in ASKREDDIT section but it seems that was not the right place for poll type question, so I post it again in this section

• Using fft2 with reshaping for an RGB filter

  - by Mahmoud Aladdin

  I want to apply a filter on an image, for example, blurring filter [[1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0]]. Also, I'd like to use the approach that convolution in Spatial domain is equivalent to multiplication in Frequency domain. So, my algorithm will be like. Load Image. Create Filter. convert both Filter & Image to Frequency domains. multiply both. reconvert the output to Spatial Domain and that should be the required output. The following is the basic code I use, the image is loaded and displayed as cv.cvmat object. Image is a class of my creation, it has a member image which is an object of scipy.matrix and toFrequencyDomain(size = None) uses spf.fftshift(spf.fft2(self.image, size)) where spf is scipy.fftpack and dotMultiply(img) uses scipy.multiply(self.image, image) f = Image.fromMatrix([[1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0]]) lena = Image.fromFile("Test/images/lena.jpg") print lena.image.shape lenaf = lena.toFrequencyDomain(lena.image.shape) ff = f.toFrequencyDomain(lena.image.shape) lenafm = lenaf.dotMultiplyImage(ff) lenaff = lenafm.toTimeDomain() lena.display() lenaff.display() So, the previous code works pretty well, if I told OpenCV to load the image via GRAY_SCALE. However, if I let the image to be loaded in color ... lena.image.shape will be (512, 512, 3) .. so, it gives me an error when using scipy.fttpack.ftt2 saying "When given, Shape and Axes should be of same length". What I tried next was converted my filter to 3-D .. as [[[1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0]], [[1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0]], [[1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0], [1/9.0, 1/9.0, 1/9.0]]] And, not knowing what the axes argument do, I added it with random numbers as (-2, -1, -1), (-1, -1, -2), .. etc. until it gave me the correct filter output shape for the dotMultiply to work. But, of course it wasn't the correct value. Things were totally worse. My final trial, was using fft2 function on each of the components 2-D matrices, and then re-making the 3-D one, using the following code. # Spiltting the 3-D matrix to three 2-D matrices. for i, row in enumerate(self.image): r.append(list()) g.append(list()) b.append(list()) for pixel in row: r[i].append(pixel[0]) g[i].append(pixel[1]) b[i].append(pixel[2]) rfft = spf.fftshift(spf.fft2(r, size)) gfft = spf.fftshift(spf.fft2(g, size)) bfft = spf.fftshift(spf.fft2(b, size)) newImage.image = sp.asarray([[[rfft[i][j], gfft[i][j], bfft[i][j]] for j in xrange(len(rfft[i]))] for i in xrange(len(rfft))] ) return newImage Any help on what I made wrong, or how can I achieve that for both GreyScale and Coloured pictures.
