  • How to calculate how many business days are between two dates?

    - by mystify
    A friend asked me yesterday if this was possible on the iPhone. I took a look at NSCalendar and all the related Classes but couldn't find a solution to this. So I thought about this approach: If I had two dates dateA and dateB, I would have to make a for-loop and iterate over every single day in this interval. Then I would count the business days monday until friday, and return the result. Then I went to bed, and I woke up with this probably much better idea: I need to know what day is it when I start. Lets say it's thursday. And then I must know how many days are in that interval. The last part is not hard to figure out. For the first part, I have no clue yet, but I believe there's an day of week value in NSCalendar. With that, I could do some simple math to calculate the amount of business days. Did anyone do that already on the iPhone?

  • Memory warning navigation controller

    - by fbiphone81
    Hi I'm new in iphone developing. The question is : I have a RootViewController with 2 uibutton. When i execute "memory monitor instrument on my iphone device OS3" RealMemory goes from 3.75M to 4.58M (I launch a uiview1controller by click on one UIbutton, then i close it and return to the RootViewController). When i close then uiview1 then memory goes to 4.22M. Why not to 3.75M? (uiview1controller is a simple test. nothing inside.) if i launch again uiview1controller memory increase from 4.22M and then retunrs to 4.22M. Correct. Then i launch uiview2controller from second uibutton. RealMemory goes from 4.22 to 6.01M. When i close the uiview1controller memory goes to 4.73M. Why not to 4.22? uiview1controller is a simple uiview with 3 uilabel and 3 uiimage designed with InterfaceBuilder and . the ONLY code write from me in uiview2controller is declare 3 iboutlet uitextfield and set uitextfileld text in loading. every time i launch the uiview2controller and close it memory increase of 0.51M ? What's worong? i tried to release iboutlet but it's the same. Thank you very much.

  • Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

    - by Carl Lindberg
    I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

  • Mac Mini's internet very slow, every other device fine (PC, iPhone, Xbox 360)

    - by alex
    I recently haven't used my Mac Mini for about 5 days (however it was left on). I seem to be able to connect and get great download / upload speeds through my PC, Xbox 360, iPhone and parents' laptop. However, my Mac Mini is very slow. OS X's Mail.app is downloading mail at 0.4kbps and then dropping to 0. Skype file transfers are doing the same. Browsing the net is a terrible experience. It is taking 30 seconds or more to download basic pages. All of my devices connect wirelessly to a Netgear router / modem. I have tried giving the Mac Mini a manual IP, and renew DHCP lease, as well as flush DNS in Terminal. I have also rebooted the router / modem twice, and the Mac Mini twice. Do you know what could be causing this? Thanks Update This is very weird. It is also very slow accessing localhost (setup through MAMP) and also slow to access the Netgear router config pages.

  • Hosting django backend for iPhone / Android app

    - by Ashok Fernandez
    I am looking to make an iPhone / Android app for my university using the Appcelerator Titanium framework. The app will rely heavily on a server backend which will pull information from other sites, figuring out what is relevant to the user then deliver the content. Some of the information is individual to the user (calendar data), other bits are updates frequently but are shared (bus timetables) and others are static and the same for everyone (magazine articles). I was going to use django as I am fairly proficent in python so I thought it would save time. My question is, which hosting services do you recommend to host the server backend? I am expecting about 9000 people to use the app with very random spikes in traffic, but unfortunately I have very little to go on at this stage. I have heard a lot about Webfaction, is it suitable for something like this or am I likely to need something bigger? I don't really want to fork out for a VPS at this stage. What about Amazons EC2? Would that be more suitable than Webfaction? Sorry for the fairly open ended question, Im sort of new to this so I open to all suggestions.

  • Some Emails incoming to Outlook 2007 are blank, same emails work fine on webmail, iphone, etc

    - by Funran
    This is a pretty easy problem to describe. Basically users who have just been upgraded to Outlook 2007 (yeah I know 2010 is out), are not receiving SOME emails (from outside our domain, ie hotmail, yahoo). Receiving is not the correct word, these emails come in, along with their attachments, subjects, to/from line, etc. But the body is blank. If the same user goes into their webmail, iphone, blackberry instead, they can read the message fine. It's clear to me that something in Outlook 2007 is not generating the body correctly, so it just strips it. I just don't know WHY. Our mail server was recently upgraded to Exchange 2010, users on 2010 running outlook 2003 are working fine, it's just the random emails for users using 2007. I hope I made that clear enough, thank you for any future help guys. EDIT: I don't see rft, but i swear I've seen it before. Here is the view source on a recent email. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><html><head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <meta name="GENERATOR" content="MSHTML 8.00.6001.19120"> <DEFANGED_style_0 <="" style=""> </head> <body bgcolor="#ffffff"> <p><DEFANGED_DIV><font color="#0000ff" size="2" face="Calibri">MS,</font></p><DEFANGED_DIV> <p><DEFANGED_DIV><font color="#0000ff" size="2" face="Calibri">Could you tell me please what the legal descrip &amp; Topo Quad name is for this Monroe P.ID Site?</font></p><DEFANGED_DIV> <p><DEFANGED_DIV><em><font color="#0000ff" size="2" face="Calibri">Thanks, Henry Roye</font></em></p><DEFANGED_DIV></body></html>

  • Can't reach only certain websites from my Wifi (with macbook and iphone)

  • UITableView issue when using separate delegate/dataSource

    - by Adam Alexander
    General Description: To start with what works, I have a UITableView which has been placed onto an Xcode-generated view using Interface Builder. The view's File Owner is set to an Xcode-generated subclass of UIViewController. To this subclass I have added working implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: and the Table View's dataSource and delegate are connected to this class via the File Owner in Interface Builder. The above configuration works with no problems. The issue occurs when I want to move this Table View's dataSource and delegate implementations out to a separate class, most likely because there are other controls on the View besides the Table View and I'd like to move the Table View-related code out to its own class. To accomplish this, I try the following: Create a new subclass of UITableViewController in Xcode Move the known-good implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: to the new subclass Drag a Table View Controller to the top level of the existing XIB in InterfaceBuilder, delete the View/TableView that are automatically created for this Table View Controller, then set the Table View Controller's class to match the new subclass Remove the previously-working Table View's existing dataSource and delegate connections and connect them to the new Table View Controller When complete, I do not have a working Table View. I end up with one of three outcomes which can seemingly happen at random: When the Table View loads, I get a runtime error indicating I am sending tableView:cellForRowAtIndexPath: to an object which does not recognize it When the Table View loads, the project breaks into the debugger without error There is no error, but the Table View does not appear With some debugging and having created a basic project just to reproduce this issue, I am usually seeing the 3rd option above (no error but no visible table view). I added some NSLog calls and found that although numberOfSectionsInTableView and numberOfRowsInSection are both getting called, cellForRowAtIndexPath is not. I am convinced I'm missing something really simple and was hoping the answer may be obvious to someone with more experience than I have. If this doesn't turn out to be an easy answer I would be happy to update with some code or a sample project. Thanks for your time! Complete steps to reproduce: Create a new iPhone OS, View-Based Application in Xcode and call it TableTest Open TableTestViewController.xib in Interface Builder and drag a Table View onto the provided view surface. Connect the Table View's dataSource and delegate outlets to File's Owner, which should already represent the TableTestViewController class. Save your changes Back in Xcode, add the following code to TableTestViewController.m: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Returning num sections"); return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"Returning num rows"); return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Trying to return cell"); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = @"Hello"; NSLog(@"Returning cell"); return cell; } Build and Go, and you should see the word Hello appear in the TableView Now to attempt to move this TableView's logic out to a separate class, first create a new file in Xcode, choosing UITableViewController subclass and calling the class TableTestTableViewController Remove the above code snippet from TableTestViewController.m and place it into TableTestTableViewController.m, replacing the default implementation of these three methods with ours. Back in Interface Builder within the same TableTestViewController.xib file, drag a Table View Controller into the main IB window and delete the new Table View object that automatically came with it Set the class for this new Table View Controller to TableTestTableViewController Remove the dataSource and delegate bindings from the existing, previously-working Table View and reconnect the same two bindings to the new Table Test Table View Controller we created. Save changes, Build and Go, and if you're getting the results I'm getting, note the Table View no longer functions properly Solution: With some more troubleshooting and some assistance from the iPhone Developer Forums at https://devforums.apple.com/message/5453, I've documented a solution! The main UIViewController subclass of the project needs an outlet pointing to the UITableViewController instance. To accomplish this, simply add the following to the primary view's header (TableTestViewController.h): #import "TableTestTableViewController.h" and IBOutlet TableTestTableViewController *myTableViewController; Then, in Interface Builder, connect the new outlet from File's Owner to Table Test Table View Controller in the main IB window. No changes are necessary in the UI part of the XIB. Simply having this outlet in place, even though no user code directly uses it, resolves the problem completely. Thanks to those who've helped and credit goes to BaldEagle on the iPhone Developer Forums for finding the solution.

  • How to repair Mac OSX without reinstalling?

    - by RahulVyas
    I have an intel PC. I have installed iDeneb Mac OS X in my pc. It's running fine. After that I thought to install Snow Leopard for running the iPad SDK. So I bought a retail Snow Leopard and boot it with Rebel EFI boot loader. When I was installing Snow Leopard, at the end of installation, setup gives an error. So I restarted my PC and boot with Rebel and I saw that mac was there so I boot that into safe mode and Mac OSX runs. After that I install iPad SDK. But when I try to create an application, XCode is not responsive. It hangs when I choose new project, give it a name and save it on disk. After just as I gave name and choose save it hangs. Is there any way i can repair my Mac OSX without reinstalling? I have also unable to boot into normal mode and also without Rebel CD. So I want to boot without Rebel CD and also want to run iPad SDK so please help me to solve this problem.

  • Mail.app does not show new mail when iPod touch is active

    - by Debilski
    I have synchronised the e-Mail settings of the iPod touch with the settings of my IMAP account in Mail.app. Now sometimes the iPod would show there are new mails with Mail.app totally ignoring their existence for hours. Only when Mail.app is restarted would these new mails show up. Is there anything I can do that Mail.app is up-to-date even though the iPod is running?

  • Keep only "lock" a single app open in iOS?

    - by CT.
    Is there anyway to "lock" open a single app in iOS? My use case for this is simple. There are many apps and games designed for children. While these applications are appropriate for children, many other applications installed on an iPad are not. But even more so than protecting them from inappropriate content, I would just like to prevent them from leaving the application. They accidentally hit the home button or multi-touch gesture out of the application. I know you can turn gestures off. Developers also have links to their website or other related applications. Kids are constantly exiting the application and then bringing the device to me asking "Can you get me back into the game?" every couple minutes. How can I hand a child an iPad with "Angry Birds" running and make sure only "Angry Birds" runs? Cydia or jailbreak tweaks welcome. Thanks.

  • European wireless data

    - by drewk
    I am on my way to Europe for 20 days with the wife and teenage kids. Among us, we have 3 iPhones, 1 Blackberry, 2 iPad 3G and 2 Macbook Pro laptops. Each has Skype. I am very concerned about AT&T data charges, and I am looking for a sensible alternative. For example, the AT&T data plans for the phones and iPads are $200 EACH for 200 MB per device. That is $1,200 and does not even cover the laptops. Ouch!!! I am thinking about a prepaid data plan from a European cell system of some sort combined with a GSM data modem and a Cradlepoint router, such as the CTR500. So, questions: 1) Anyone know of a GSM data source in Europe where I can buy a GSM Modem compatible with the CTR500 at a reasonable prepaid rate? 2) Experience with the CTR500?

  • Multitasking on iOS4 and its stated battery efficiency

    - by eml
    Apple stated that the reason multitasking didn't arrive before iOS4 is because they hadn't figured out how to do it right. Jobs stated at Apple WWDC 2010 that they now do and that they solved the problem of preserving battery performance regarding multitasking. Is iOS4's multitasking "feature" indeed more efficient regarding battery performance compared to Android? Have the Android developers managed to "do it right" too?

  • Why do my Xcode default font starts to look ugly after some time, until I restart?

    - by mystify
    I plugged in an external monitor. All resolutions match perfectly. MacBookPro LCD is closed. After restarting Xcode editor fonts look very bad. Only in Xcode. When I restart the mac and DON'T use an external monitor, fonts look all right again. When I attach the monitor and close the LCD of the MacBookPro, fonts look nice. Then I close Xcode and reopen it: Fonts suck. Only way to get fonts look good is to disconnect external monitor and reboot, then reconnect external monitor, close LCD, wait, hit any key and let the external monitor be the only one. Fonts look nice - until I restart Xcode. I think it happens any time Xcode is launched with external monitor attached and ugly fonts survive until reboot. Unplugging external monitor and restarting Xcode doesn't help. It seems like Xcode isn't antialiasing them properly after something happens. Is there a fix for this problem? EDIT: After trying a few more times, it seems it is possible to get fonts to look nice by disconnecting external monitor and reopening xcode. Here are some little snapshots: GOOD FONT: UGLY FONT: You can see how dirty the ugly font looks. It's very hard to read and hurts in the eyes. Believe me. It sucks. Sometimes the little "i" are almost invisible. I make use of the very eye-friendly Dusk style of Xcode (go to preferences and choose that, if you haven't already. A real pleasure for your eyes)
