  • Problem in getting response from webserver

    - by Amarpreet
    Hi guys I am sending data to webserver in the Querystrings by creating URL dynamically. When I view that URl in UIAlertView it shows me correct one. And when i try to get response using NSURL code, it does not respond. Below is the code. NSString *uu = @"http://www.zenhomeenergy.com/ZenIphoneServUpdate.aspx?CustomerID=12&FirstName=Andrew&LastName=Turner&State=SA&Street=60 Highfiled Drive Hillbank no phone number&PostCode=5112&Email= &Mobile= &HomePhone= &WorkPhone= &PrimaryResidence=True&HomeOwner=True"; NSString *text = [NSString stringWithContentsOfURL:[NSURL URLWithString:uu]]; if(text) { if([text isEqualToString:@"Success."]) { textView.text = [textView.text stringByAppendingString:@"Success.\n"]; } else { textView.text = [textView.text stringByAppendingString:@"Failed.\n"]; } } If you try putting the above URL into browser it says "Success." But the code above doesnot work. Please Help.

  • Form.cs not being updated by changes to Form.cs[Design]

    - by Kevin
    I am new to Visual Studio and I am just messing around with the controls to see how things work. I made one form that had a single button that, when pushed, simply printed "Hello World" to the screen. To try something more complicated I deleted that button and added various other tools to the Form. However the code in the Form.cs file was not updated to reflect these changes to the design and I can find no way to update it manually. Any advice is appreciated. Regards.

  • Any way to animate new elements in a GridView being added?

    - by Ben L.
    My app polls a server every 15 seconds to see if there are any new items to display, then downloads the new items and disposes of the old items so that there are always exactly 100 items in the GridView. Unfortunately, this process can be confusing to the user if they see a page of images change without knowing where the items went. My idea is that there could be some kind of animation (such as the new items being inserted at the top and pushing the older ones down the list) to show what action is happening. Unfortunately, I have no clue how to make this animation happen. Is my idea even possible? How would I accomplish this?

  • Can't add to NSMutableArray from SecondaryView

    - by Antonio
    Hi guys, I've searched and read and still haven't found a concrete answer. Brief: I have an application where I declare an NSMutableArray in my AppDelegate to synthesize when the application loads. (code below). I have a SecondaryViewController call this function, and I have it output a string to let me know what the array size is. Every time I run it, it executes but it does not add any objects to the array. How do I fix this? AppDelegate.h file #import <UIKit/UIKit.h> @class arrayTestViewController; @interface arrayTestAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; arrayTestViewController *viewController; NSMutableArray *myArray3; } @property (nonatomic, retain) NSMutableArray *myArray3; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet arrayTestViewController *viewController; -(void)addToArray3; @end AppDelegate.m file #import "arrayTestAppDelegate.h" #import "arrayTestViewController.h" @implementation arrayTestAppDelegate @synthesize window; @synthesize viewController; @synthesize myArray3; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { myArray3 = [[NSMutableArray alloc] init]; // Override point for customization after application launch. // Add the view controller's view to the window and display. [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } -(void)addToArray3{ NSLog(@"Array Count: %d", [myArray3 count]); [myArray3 addObject:@"Test"]; NSLog(@"Array triggered from SecondViewController"); NSLog(@"Array Count: %d", [myArray3 count]); } SecondViewController.m file #import "SecondViewController.h" #import "arrayTestAppDelegate.h" @implementation SecondViewController -(IBAction)addToArray{ arrayTestAppDelegate *object = [[arrayTestAppDelegate alloc] init]; [object addToArray3]; }

  • Is there an easy way to change iPhone Application Settings from within an application?

    - by Matt
    I've got application settings working just fine. However, I'd like to be able to change my app settings from within my app. It seems as though there should be some kind of generic way to add this functionality to my app without having to recreate all the controls myself. I mean, the code is already written in apple's settings app. Maybe someone wrote this code and open sourced it? (if it is not already available)

  • How to change the UIImageView image content by code?

    - by Tattat
    I use this to assign image: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; CGImageRelease(imageRef); Now, I want to change the image from myImage to myImage2, so I do that: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage2" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; It works, but not the way I want, I want to change the image, not add a imageView on top of the pervious one. How can I modify my code? thx u.

  • UITextView disabling text selection

    - by dizy
    I'm having a hard time getting the UITextView to disable the selecting of the text. I've tried: canCancelContentTouches = YES; I've tried subclassing and overwriting: - (BOOL)canPerformAction:(SEL)action withSender:(id)sender (But that gets called only After the selection) - (BOOL)touchesShouldCancelInContentView:(UIView *)view; (I don't see that getting fired at all) - (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view; (I don't see that getting fired either) What am I missing ?

  • iPad Orientation Lock Notification?

    - by vakio
    Is there a way to receive a notification when the iPad gets locked? When the lock is set on or off, it does send a receivedRotate: notification, but I need a way to be able to distinguish normal rotations from lock "rotations". The problem is I am rotating things in my view when the rotation changes. When the lock is activated, the iPad sends a receivedRotate: with UIInterfaceOrientationPortrait. I've looked in UIDevice for something like isOrientationLocked, but with no success. Thanks for any clues on this.

  • Custom cell and Delete/Move indicators

    - by Kamchatka
    Hello, I have a custom UITableViewCell. However, when I got in edit mode, I don't have any Delete and Move indicators appearing. The custom cell draws itself in the contentView. In layoutSubviews, I make sure there is space on the left and one the right of the contentView so that the controls can appear (if this was the problem). - (void)layoutSubviews { self.contentView.frame = CGRectMake(50, 0, self.frame.size.width - 100, sub.thumbnail.size.height + 20); } In the UITableViewController, I return YES in: - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { How could I solve this lack of interactivity. Is there something specific for custom cells? Thanks!

  • touchesMoved QuartzDemo application

    - by BittenApple
    I am modifying the QuartzDemo application to include swipe detection while UIView is active (a PDF page being displayed in it via Quartz). This will not work, the event never gets to the QuartzView.m because it sits under scrollview? touchesBegan works fine and I can use single tap. How can I go about with catching touchesMoved while PDF page is being displayed? I need a simple example with code that does nothing on touchesMoved, I'll build up on that later. Please keep in mind that I still want to use the UIScrollview as it is and show PDF content based on selection in that scrollview.

  • How to NSZombieEnabled for debugging EXC_BAD_ACCESS on release target for an iPhone app?

    - by Bobby Moretti
    I'm developing an iPhone application. I have an EXC_BAD_ACCESS that occurs only in the release target; when I build the debug target the exception does not occur. However, when I set the NSZombieEnabled environment variable to YES, I still get the EXC_BAD_ACCESS with no further information. Is it even possible for NSZombieEnabled to work when executing the release target? I don't see why not, since gdb is running in both cases...

  • iPhone Camera and Image Chooser

    - by PF1
    Hi Everyone: I have found a lot of information on using UIImagePickerController to let the user choose the image they want from the Photos application's data. I am wondering how I can create this same effect on 3.0, as it doesn't seem as if a lot of the old code works anymore. In addition, I would like the user to be able to take a new picture from this same pop-up. Thanks for any help!

    That's what I have: - A table with a few rows, one column only What I am trying to accomplish: Double tap on any row should produce an animation of the cell.

Is it possible? If yes, how?
