• UIWebView EXC_BAD_ACCESS crash

  - by HARDWARRIOR

  I'm experiencing crashes of an app that uses UIWebView. Usually it's when page is not fully loaded and UIWebView is sent stopLoading selector. Or when UIWebView fully loaded page. I've got EXC_BAD_ACCESS. Stack looks like this: #0 0x95bb7688 in objc_msgSend #1 0x30a671db in -[UIWebView webView:decidePolicyForNavigationAction:request:frame:decisionListener:] #2 0x3024a10d in __invoking___ #3 0x30249ff8 in -[NSInvocation invoke] #4 0x358ab160 in HandleDelegateSource #5 0x302452c1 in CFRunLoopRunSpecific #6 0x30244628 in CFRunLoopRunInMode #7 0x32044c31 in GSEventRunModal #8 0x32044cf6 in GSEventRun #9 0x309021ee in UIApplicationMain #10 0x0000239c in main at main.m:13 for me most strange thing here is webView:decidePolicyForNavigationAction:request:frame:decisionListener: selector sent to UIWebView, because there is no such selector in UIWebView documentation! Only for Cocoa (not cocoa touch) WebView. I suspect that there is something wrong with UIWebView or its delegate. But I can't set breakpoint to watch them. Please advise how I can get more info in this situation.

• Unexpected resume of "package name" while already resumed in ''package name" Error in Android

  - by Janusz

  If changing the orientation of my phone or the emulator I get the following output in LogCat: 04-09 11:55:26.290: INFO/WindowManager(52): Setting rotation to 1, animFlags=0 04-09 11:55:26.300: INFO/ActivityManager(52): Config changed: { scale=1.0 imsi=310/260 loc=en_US touch=3 keys=2/1/1 nav=3/1 orien=2 layout=18} 04-09 11:55:26.460: INFO/UsageStats(52): Unexpected resume of client while already resumed in client 04-09 11:55:26.579: INFO/SearchPosition(807): Activity is paused 04-09 11:55:26.689: INFO/SearchPosition(807): Activity is resuming SearchPosition is the activity that is displayed. Activity is paused is written in the onPause Method and Activity is resuming in the onResume method of the activity. I googled a little bit for the error message but I don't fully understand the meaning of it. I think it could mean that the old Activity is not properly destroyed after changing the screen orientation. Is this correct? If yes what causes the error? If this is not correct? What is the meaning of this output?

• Embedding an offline Dashcode application in a UIWebView in an iPhone application

  - by Nimrod

  In order words, can anyone tell me the basics of how to create a "hybrid" iPhone application? I want to load the web content (the Dashcode app itself) from the native application's application bundle. I've gotten this to partially work, but some content won't display and it otherwise seems like Dashcode is assuming a certain Safari environment or something that I don't seem to have in my UIWebView. Can anyone provide a link to some sample code that embeds a Dashcode project into a cocoa touch Xcode project? (I did search around Google for a bit trying to find something and I failed to come up with anything worthwhile, except for some books that I might eventually buy if the approach seems worthwhile.)

• Disabling Magnifying Glass in UITextView in an iPhone App

  - by tgm

  I want to display text and I want to be able to know where in this text a user touches. Because the text could be long, I wanted to use a UITextView so that wrapping and everything would be taken care of. I want my own event handling for when a touch begins or moves. My problem is that the magnifying glass and select/select all menu are interrupting my touchesMoved events. How can i disable the magnifying glass, but still have user interaction enabled so that I can detect the touches?

• Delphi 2010 Professional and remote database access

  - by Kico Lobo

  Hi, When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Does this mean that we'll only face this restriction if we choose to use the native vcl components for database access we'll face this restriction. And what if we choose to use ADO components instead of those? In this case, how can Delphi avoid us to access remote database servers? Did anyone here ever tried this? Going even further: if we choose to use a database like Firebird, which is just one file, and used a network mapped drive. Could we be facing the same limitation? Supposing we opt for ADO, what will be the main consequences?

• Multiple calls with Simple Modal OSX Style Dialog

  - by Brad Langdon

  I am using Simple Modal, the OSX style version. I have two calls to the modal and therefore two versions of content. When either of the buttons is clicked it selects only the first lot of content. There is nowhere to put a hook on the content like most modal windows as there is no javascript on the page to add parameters... only an external .js file which I don't want to touch for obvious reasons. Can anyone help me with this problem? Click here to view the page

• AdMob ads on Android app are not rotating / refreshing

  - by Ben Mc

  Has anyone else had this problem? I have a game, and the Ads show at the top of the phone above my game view. When I'm tapping away on the game, the ads just stay the same. BUT, if I don't touch anything and wait the 15 seconds, as is set in my Interval, THEN the ad changes (usually). I don't get any error reports. There's nothing to indicate that this shouldn't be working just fine, but I have no idea why my ads aren't refreshing or rotating while I'm interacting with the other View in my application. Any direction or thoughts would be helpful, thank you!

• 10 lines of code per day is the global average!? -- true?

  - by Earlz

  Ok so last year I participated in a high school curriculum contest thing at a college(I currently attend this college). I actually got 1st in it but was still a bit angry I didn't get every single one right. The most baffling of questions on there was How many lines of code does the average programmer write per day? A. 5 B. 10 C. 25 D. 30 Aside from being a subjective question which depended on language and everything else I was more baffled at what they had as the correct answer. 10. Even on my bad days at my job I touch more than 10 lines of code(either adding, modifying, or deleting) per day. And when I took this test I had only programmed as a hobby where it was common for me to write a few hundred lines for one of my new projects per day. Where are they getting this random number of ten!? Is this published somewhere? A quick googling found me nothing.

• iphone dev: UIImageview subclass interface builder - how to call custom initializer

  - by ninjasmith

  hi. I messing with iphone developement. I have a uiimageview subclass that I want to use to detect touches. I have sucessfully added to interfacebuilder and I can detect a touch in my UIImageview subclass within my application so all is good on that front. however my UIImageView subclass has a custom initializer which is not called when it is created in interface builder. if I manually initialize the UIImageview and add it programmatically I think it will work but then I lose the ability to 'see' my positioning in Interface builder. how can I either 1) 'see' a uiimageview in interface builder that is added in code? (not possible?) 2) call my custom initializer when the subclass is instantiated in interfacebuilder. thanks

• PostgreSQL / Ruby for commercial application

  - by RPK

  I am planning a web-based commercial application with front-end RoR and back-end PostgreSQL. I've some confusion about RoR and PostgreSQL Edition to use. For RoR, I have Aptana RADRails installed. For PostgreSQL, a free variant is also available at EnterpriseDB. Previously I installed a free EnterpriseDB PostgreSQL variant and it was very smooth and had professional touch. It was quite different from the one available from PostgreSQL website. I want to know which IDE and RoR variant to use for my project. I have no idea of Ruby and Rails. I will be learning and developing simultaneously. Also, which PostgreSQL variant to use? Can these two technologies be used for a developing a commercial application?

• Two Questions on for Rsync - rsync by date and by file name

  - by paulj3000

  Hi, I have two questions with respect to rsync: 1: I have a bunch of files which are incremented by day of the year. Ex: file.txt.81, file.txt.82, etc. Now, these files are in different directories: data1/file.txt.81 data1/file.txt.82 data2/file2.txt.81 data2/file2.txt.82 How can I have rsync get only the *.82 files and not even touch the other files 2: Now I have a similar data directory structure as above. How can I rsync all files that have been modified on or after a specific day? Thanks

• Benefits of programming (doing) versus reading blogs (thinking?)

  - by Xian

  I have come to a conclusion or realization that perhaps many developers I know including myself have a fanatical fascination with reading as many programming and technology blogs or listening to podcasts as humanly possible. I sometimes wonder if this time would be much better spent in actual coding and doing, rather than the incessant thinking and perhaps wondering what the "other guy" is doing? With a very large signal to noise ratio in most blogs and podcasts, is there real benefit in maintaining a huge and constant blog role.. or is this some primal fear or instinct to keep up the pace unless being left behind? Can they simply be relegated to Google search and just-in-time learning? Edit: (There are some amazing answers here and touch a philosophical nerve with me, if you are reading this for the first time, I recommend taking the time reading through the answers below)

• UITableView background customization strange behavior

  - by Omer

  Hi, There is a couple of hours that I'm trying to set a tableView background image. My controller is a subclass of UITableViewController, and I simply wrote this lines of code in ViewDidLoad method. UIImage *image = [UIImage imageNamed:@"home-portrait-iphone.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; self.tableView.backgroundView = imageView; Everything looks great on the simulator, I mean, I see my table and as background view, y can see the image. But when the app is running on the device (ipod touch), I get this error: Program received signal: “SIGABRT”. and the stack says: * -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00' and the exception is thrown in the assignment, a mean this line: self.tableView.backgroundView = imageView; any ideas? Thank you in advance.

• naive bayesian spam filter question

  - by Microkernel

  Hi guys, I am planning to implement spam filter using Naive Bayesian classification model. Online I see a lot of info on Naive Bayesian classification, but the problem is its a lot of mathematical stuff, than clearly stating how its done. And the problem is I am more of a programmer than a mathematician (yes I had learnt Probability and Bayesian theorem back in school, but out of touch for a long long time, and I don't have luxury of learning it now (Have nearly 3 weeks to come-up with a working prototype)). So if someone can explain or point me to location where its explained for programmers than a mathematician, it would be a great help. PS: By the way I have to implement it in C, if you want to know. :( Regards, Microkernel

• Android installation in a mobile

  - by Sundar

  Is it possible to install Android in a normal mobile phone? I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-). Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile? Any pointer/suggestion is appreciated. Thank you in advance.

• MKMapView within UITableView

  - by john-london

  I have a MKMapView within a UITableviewCell and I want to be able to disable scrolling of the table view when the user starts to drag within the map view. My plan had been to override the MKMapView touchesBegan/Moved etc methods and if they were called to then disable scrolling in the parent view. Scrolling in the parent view would be enabled again only when the touches in the MKMapView ended or were cancelled. My problem is that the touchesBegan/Moved methods inside MKMapView are not called - the problem is also discussed here: stackoverflow discussion. My table view is within a tab control, so I don't think I can extend UIWindow the way they describe, as there are several views that could be within the window, depending on which tab is active. How can I access the MKMapView touch events please?

• PROPSHEETHEADER and PSH_PIVOT to get the horizontal pivot scroll?

  - by Johann Gerell

  Windows Mobile 6.5.3 has a "touch friendlier" pivot at the top of the screen instead of tabs at the bottom. In the docs for PROPSHEETHEADER, the dwFlag value PSH_PIVOT is documented: PSH_PIVOT Applies to Windows Mobile 6.5.3 Replaces dialog box tabs with a simple pivot (horizontal spinner). It's supposed to bed defined in prsht.h, but it's not. My 6.5.3 and 6 headers differ only in this: #define PSM_GETPIVOTCONTROL (WM_USER + 119) #define PropSheet_GetPivotControl(hDlg) \ (HWND)SNDMSG(hDlg, PSM_GETPIVOTCONTROL, 0, 0) which is in the 6.5.3 prsht.h, but not in the 6 one. What's the value of PSH_PIVOT? Did they forget to include it?

• Awstats showing 404s for pages and objects I definitely don't have...

  - by Andrew Heath

  I have a HostGator site using Awstats and I've recently noticed the following 3 bizarre 404s: [address] [times] /images/wikimedia-button.png 1 /apple-touch-icon.png 1 /imgs/custom-space.gif 1 the first and third also carry referrers from within my site, but are 100% definitely absolutely not linked by any of my pages. I'm not too worried about it, seeing as each one has only popped up once. But I am concerned about why Awstats thinks one of my pages is referring what is apparently a wikipedia image, and why Steve Jobs is trying to haxx0r me (/joke) This is my first site to receive moderate daily usage, so I'm curious if these sorts of unique weird-o 404s just come with the territory, or if I should be double-checking something... Thanks!

• iphone - button outside MPMoviePlayerController window not responding

  - by Mike

  I have created a MPMoviePlayerController to play a movie. As the movie likes to play landscape in full screen, when the movie is about to play, I grab its window and resize it to be smaller. At the same time, I add a view to the movie's window and this view contains several buttons, that are supposed to be around the movie. As the movie's window is reduced in size, I have to scale the buttons' view up, so the buttons do not reduce in size. I ended with this What you can see here is this: four buttons (green rectangles), the reduced movie's window and the application's window, that now is visible because the movie's window was reduced. The problem is that the buttons just work if you click on their regions inside the movie's window (A). If you click them on the region outside (B) they don't work. WHen you click on B, TouchesMoved on the main view controller receives the touch and the button doesn't do its action. How can this be solved? thanks for any help

• Iphone UIScrollView and multiple visible images

  - by joynes

  Hi! Im trying to implement a UIScrollView including multiple images, using paginate. The problem is that I want more then one page to be visible in the UIScrollView, but only one page should be selected. I found several solutions in which you handle touch down/up (touchesBegan and touchesEnded) myself and scrollRectToVisible, but I want to avoid this if possible. A sample solution for that can be found at: http://forums.macrumors.com/showthread.php?t=634462 I dont get why its so easy if you only need to display one page at a time in the UIScrollView , but seems really hard if you want to show more pages. Could you solve it with zooming? /Br Johannes

• How to start develop for chinese mobile phones based on nucleus RTOS? (MTK)

  - by juckobee

  I've noticed that chinese mobile phones became very popular, perhaps because of their very reasonable price and many modern features (touch screens, advanced multimedia, double sim cards etc). I'm wondering if there's any way to develop custom solutions for this handsets as independent developer? How to obtain a toolkit and documentation? I've found some resources, but mainly inconsistent tech notes, often in chinese only. For now I know, that majority of chinese handsets are based on chips from MediaTek (MTK), with operating system based on Nucleus RTOS and MMI (plutoMMI?) framework. Unfortunately, there is no Java RE avaiable (ok, there are some handsets with Java, however, Java isn't something I'm looking for) Is there any SDK, documentation, emulators/simulators, how-tos, etc avaiable? How to develop, deploy and test custom application for MTK mobile?
