  • sqlite on iphone can open db but not prepare statements

    - by jan
    I'm brand new to using sqlite so I may have missed something basic. I've created a database and copied it into my app's document's directory. I'm able to open it but when I make a call to sqlite3_prepare_v2 I receive SQLITE_ERROR, "SQL error or missing database". here's my code: sqlite3 *database; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { sqlite3_stmt *compiledStatement; NSString *sqlStatement = @"select * from dbname"; int result = sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, nil); ... } the same sql statement works in the terminal. I've found this question in a few places either without answers or with solutions that don't fix my problem. I'm hoping someone here will be able to help. Thanks.

  • How to conform to UITabBarControllerDelegate

    - by 4thSpace
    I have a tabbar based application and do the following to get a reference to the application delegate: MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; Which then gives this warning: warning: type 'id <UIApplicationDelegate>' does not conform to the 'UITabBarControllerDelegate' My application delegate header looks like this: #import <UIKit/UIKit.h> @interface MyAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end The only methods in the .m file are applicationDidFinishLaunching and dealloc. What else do I need to conform to the protocol?

  • Python and App Engine project structure

    - by Joel
    Hello, I am relatively new to python and app engine, and I just finished my first project. It consists of several *.py files (usually py file for every page on the site) and respectively temple files for each py file. In addition, I have one big PY file that has many functions that are common to a lot of pages, in I also declared the classes of db.Model (that is the datastore kinds). My question is what is the convention (if there is one) of arranging these files. If I create a model.py with the datastore classes, should it be in different package? Where should I put my template files and all of the py files that handle every page (should they be in the same directory as the one big common PY file)? I have tried to look for MVC and such implementations online but there are very few. Thanks, Joel

  • How can we change color of a text programmatically ?

Answers will be greatly appreciated!

  • Preventing mouse emulation events (ie click) from touch events in Mobile Safari / iPhone using Javas

    - by Jaime Cham
    In doing a single page Javascript app with interactive DOM elements I've found that the "mouseover-mousemove-mousedown-mouseup-click" sequence happens all in a bunch after the "touchstart-touchmove-touchend" sequence of events. I've also found that it is possible to prevent the "mouse*-click" events from happening by doing an "event.preventDefault()" during the touchstart event, but only then, and not during the touchmove and touchend. This is a strange design, because because it is not possible to know during the touchstart yet whether the user intents to drag or swipe or just tap/click on the item. I ended up setting up a "ignore_next_click" flag somewhere tied to a timestamp, but this is obviously not very clean. Does anybody know of a better way of doing this, or are we missing something? Note that while a "click" can be recognized as a "touchstart-touchend" sequence (ie no "touchmove"), there are certain things, such as keyboard input focus, that can only happen during a proper click event.

    - by Magician Software
    Hi There, can anyone tell me what I am doing wrong. I am trying to load a UIScrollView in a UIView. I am using IB to load the items and what not. the come I am using in the ViewController isnt working. :( I have it under the ViewDidLoad - (void)viewDidLoad { [scrollView setScrollEnabled:YES]; [scrollView setContentSize:CGSizeMake(768, 1300)]; } Whats wrong with it. It builds fine. While I am asking, how do you set the scroll view to strech when the iPad is rotated? Thanks for your help

  • UITextView Scrolling - Artificial Limit

    - by Matt Winters
    I have a UITextView with a height of let's say 300. What I would like is when the typed text gets to the half way point, for the scrolling to start as if it were at the bottom of the textView. Basically I would like to programmatically set the point within the textView for scrolling to begin. Any ideas? Thanks.

  • Create a screen like the iPhone home screen with Scrollview and Buttons

    - by Anthony Chan
    Hi, I'm working on a project and need to create a screen similar to the iPhone home screen: A scrollview with multiple pages A bunch of icons When not in edit mode, swipe through different pages (even I started the touch on an icon) When not in edit mode, tap an icon to do something When in edit mode, drag the icon to swap places, and even swap to different pages When in edit mode, tap an icon to remove it Previously I read from several forums that I have to subclass UIScrollview in order to have touch input for the UIViews on top of it. So I subclassed it overriding the methods to handle touches: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //If not dragging, send event to next responder if (!self.dragging) [self.nextResponder touchesBegan:touches withEvent:event]; else [super touchesBegan:touches withEvent:event]; } In general I've override the touchesBegan:, touchesMoved: and touchesEnded: methods similarly. Then in the view controller, I added to following code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; UIView *hitView = (UIView *)touch.view; if ([hitView isKindOfClass:[UIView class]]) { [hitView doSomething]; NSLog(@"touchesBegan"); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // Some codes to move the icons NSLog(@"touchesMoved"); } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesEnded"); } When I run the app, I have the touchesBegan method detected correctly. However, when I tried to drag the icon, the icon just moved a tiny bit and then the page started to scroll. In console, it logged with 2 or 3 "touchesMoved" message only. However, I learned from another project that it should logged tonnes of "touchesMoved" message as long as I'm still dragging on the screen. (I'm suspecting I have the delaysContentTouches set to YES, so it delays a little bit when I tried to drag the icons. After that minor delay, it sends to signal back to the scrollview to scroll through the page. Please correct me if I'm wrong.) So if any help on the code to perform the above tasks would be greatly appreciated. I've stuck in this place for nearly a week with no hope. Thanks a lot.

  • jQTouch Spinning Wheel (Cubiq) Implementation Won't Work

    - by Peter
    I am trying to get a nice Spinning Wheel working within my webapp; http://bit.ly/89oWud However, I keep receiving an error within Mobile Safari that the variable 'blabla' cannot be found. I have implemented both of these suggested solutions: 1# Change SpinningWheelCSS 2# Change JQTouch CSS, JS files, and add JQTouch wrapper to body Neither worked for me. I am trying to use the incredible Spinning Wheel by Cubiq.org. I'm likely doing something wrong, but for the life of me I can't figure out what it is. Help is very much appreciated.

  • View controller is drawing under my navigation bar after popping ttthumbsviewcontroller

    - by scootklein
    I'm implementing the TTThumbsViewController from the Three20 project and things are finally starting to take shape. I push the TTThumbsViewController from the current view controller by just pushing it onto the current stack and animate the transition (common navigation controller push). My problem is that when I pop the TThumbsViewController view controller, the navigation controller is stuck in a mode where its view controllers are drawn UNDER the navigation bar (which is now translucent). Start Push Pop

  • Cannot run code on device

    - by lostInTransit
    Hi I have some source code which I had developed and later gave to another team. They signed it with their certificate and provisioning profile. Now I have the code back and have set the appropriate values in the project properties for code signing identity (with my cert and profile). But when I run the application on a device, I get an error showing the other team's certificate and prompting that the provisioning profile does not exist. I don't know where it is being referenced. Can someone please help. Thanks.

  • Get Name by Cellphone number

    - by ganti
    Hy everyone I'm using a TextField where the user is typing in a phonenumber. When the TextField has changed it should check if this number is allready in the phonebook and display the name. So far, my only way is to parse all names and number in a Dict and read it from there. Is there a simpler more efficient and sophisticated way to do that. cheers simon

  • UITableView resizing rows problem

    - by Vin
    Hi All, Hope to get solution to this problem. I have been stuck on it since a long time now. I have a a tableView which has custom labels drawn upon the cell using CGRect. I receive the data from a web service in arrays. Initially i display a line of data on the cells. When the user selects a cell, I call reloadsRowAtIndexPath to increase the height of selected row. In the process, cellForRowAtIndexPath gets called again. I keep track of this by a flag, and when cellForRowAtIndexPath gets called again, I display the two more lines of data from arrays, on the cell. What i am getting is all overlapping data on one other. I tried to remove already placed labels in didSelectRowAtIndexPath, but to no avail. Please help me on this Thanks in advance.

  • Mapkit: Only show annotations in current view

    - by Nic Hubbard
    Instead of loading all annotations that are in my array, I would only like to load the annotations that the user could currently see cased on how far they are zoomed in on the map. So, if the user pans to a place where there are annotations, those would be added, and if they pan away, those would be removed. I assume this would help with memory. Does anyone know how to do something like this? And, is it worth it, or needed?

  • How to use Pisa on Google App Engine to generate PDF from HTML\CSS

    - by systempuntoout
    I'm developing a simple GAE application that crawl some data from a given site and present it formatted in html\css. What i would like to do now is to offer the "Export to PDF feature" trasforming the formatted html\css to PDF. I've imported Reportlab Toolkit and it works good but it's not what i need since it forces me to create PDF manually like: pcanvas.drawString(10, 10, 'This is the title Blah blah blah') What i really need is a library like PISA that trasform Html\Css to PDF. Anyone has managed to succesfully intregrate and use PISA on Google App Engine? Any hints?

  • Objective C: Create arrays from first array based on value

    - by Nic Hubbard
    I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

  • Date Picker Blue

    - by Matt Winters
    I'm successfully setting a date-picker with an initial date from a plist, but I see some unwanted blue values in the month, day, and year components, presumably corresponding to current date. So if today is April 18, 2010 and initial date being set is March 19, 2008, it looks like this (bold represents the blue): January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 First question is: How do I get rid of the blue? And second question: Ideally, how do I get it to look like this? January 17 2006 February 18 2007 ------------------------------ March 19 2008 ------------------------------ April 20 2009 May 21 2010 Third question, totally unrelated and not as important: How could I have gotten the above to show in blue rather than bold? I see blue in code snippets all the time. Matt
