  • UIImage cropping on user selected rectangle in iphone?

    - by Rajendra Bhole
    Hi, I developing an small application in which i want to crop the UIImage captured by imagePickerControllerSourceTypeOfCamera. The UIImage should crop by user selected crop area or cropped rectangle. That means first user capture the image from the camera.Then on captured image the user selected an rectangle having color gray.That image(image data) should crop from that gray colored rectangle. My under develop code is as follows. -(IBAction) getPhoto:(id)sender { UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; if((UIButton *) sender == btnphotoAlbum) { imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } else { imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; } imagePickerController.allowsImageEditing = YES; //imagePickerController.toolbar.barStyle =UIBarStyleBlackOpaque; //UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 20, 320)]; //imagePickerController. [self presentModalViewController:imagePickerController animated:YES]; } (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { UIImage *selectedImage = image; UIImage *originalImage = [editingInfo objectForKey:@"UIImagePickerControllerOriginalImage"]; NSValue *cropRect = [editingInfo objectForKey:UIImagePickerControllerCropRect]; CGRect theRect = [cropRect CGRectValue]; //captureImage.image =[info objectForKey:@"UIImagePickerControllerOriginalImage"]; [picker dismissModalViewControllerAnimated:YES]; } How i crop the image?

  • iPhone Icon file in bundle blank when building for App store distribution

    - by Boiler Bill
    I have been spinning my wheels for a couple hours on why when I build my app with my distribution cert with the device as the target the Icon.png file in the bundle is empty. If I build with my developer cert or against the simulator the Icon.png in the bundle matches the one in my project file. I have verified my Icon.png is 57X57, has no alpha channel, had extra finder attributes removed. I even took one of the Icon.png files from my first application that is in the store today, and it didn't work either. Here is the output from the build results: CopyPNGFile build/Distribution-iphoneos/myApp.app/Icon.png Icon.png cd /Users/wrbarbour/projects/myAppTWO/myApp setenv COPY_COMMAND /Developer/Library/PrivateFrameworks/DevToolsCore.framework/Resources/pbxcp setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" "/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneOS Build System Support.xcplugin/Contents/Resources/copypng" -compress "" /Users/wrbarbour/projects/myAppTWO/myApp/Icon.png /Users/wrbarbour/projects/myAppTWO/myApp/build/Distribution-iphoneos/myApp.app/Icon.png Can someone get me pointed in the right direction?

  • iPhone: In landscape-only, after first addSubview, UITableViewController doesn't rotate properly

    - by Clay Bridges
    A minimal illustrative Xcode project for this is available on github. On my UIWindow, when I add second (and subsequent) UITableView's as subviews, they do not rotate properly, and thus appear sideways. This is only tested in the Simulator. Here's a little code for you: - (void)applicationDidFinishLaunching:(UIApplication *)application { ShellTVC* viewA = [[ShellTVC alloc] initWithTitle:@"View A"]; ShellTVC* viewB = [[ShellTVC alloc] initWithTitle:@"View B"]; // The first subview added will rotate to landscape correctly. // Any subsequent subview added will not. // You may try this by various commentings and rearranging of these two statements. [window addSubview:[viewA tableView]]; [window addSubview:[viewB tableView]]; [window makeKeyAndVisible]; } viewB appears sideways. Comment out the addSubview for viewB, and viewA appears correctly. Do that for viewA only, and viewB appears correctly. I am not creating these UITableViewControllers via NIBs, though the UIWindow is. In case you are wondering, ShellTVC is-a UITableViewController, and implements this method: - (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft); } Also, I have set the UIInterfaceOrientation in the plist file to UIInterfaceOrientationLandscapeLeft. Probably related -- and unanswered -- SO questions here and here.

  • Best FTP Objective-C wrapper for iPhone

    - by jamone
    I know you use the C based networking API to do FTP communication but I'd prefer to use something a little higher level. I've seen a few Objective-C based wrappers but I'm not sure what to use. I don't need that complex of FTP interaction. Its just the typical create/delete dirs, upload/download files... What do you recommend?

  • switch views using a button, going to a table view, iphone

    - by Jaime Rae
    My program has 4 buttons and each button calls a different table view. That works fine, but my problem is, the view controller I'm using brings up a table view that covers up my navigation bar and my tab bar. I need to replace that coding with something that will bring up a table and not cover up my nav and tab bars. Here is the coding I'm using: -(IBAction)buttonNorthWest { NorthWestViewController *nwController = [[NorthWestViewController alloc] initWithNibName:@"NorthWestView" bundle:nil]; self.nwViewController = nwController; [self.view insertSubview:nwViewController.view atIndex:0]; [self presentModalViewController:nwViewController animated:YES]; [nwController release]; } The [self presentModalViewController....] is the problem. Does anyone know how I can replace that code with something that keeps my nav and tab bars? Thanks, Jaime

  • iPhone: Override UIButton buttonWithType to return subclass

    - by Amagrammer
    I want to be able to create a UIButton with an oversized responsive area. I know that one way to do that is to override the hitTest method in a subclass, but how do I instantiate my custom button object in the first place? [OversizedButton buttonWithType: UIButtonTypeDetailDisclosure]; doesn't work out of the box because buttonWithType returns a UIButton, not an OversizedButton. So it seems like I need to override the buttonWithType method as well. Does anyone know how to do this? @implementation OversizedButton + (id)buttonWithType:(UIButtonType)buttonType { // Construct and return an OversizedButton rather than a UIButton // Needs to handle special types such as UIButtonTypeDetailDisclosure // I NEED TO KNOW HOW TO DO THIS PART } - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { // Return results if touch event was in oversized region // I ALREADY KNOW HOW TO DO THIS PART } @end Alternatively, maybe I could create the button using alloc/initWithFrame. But the buttonType property is readonly, so how do you create the custom button types? Note: I know there are other ways to do this, such as having an invisible button behind the visible one. I don't care for that approach and would prefer to avoid it. Any help on the approach described above would be very helpful. Thanks

  • iPhone NSXMLParser parsing string and storing in a NSNumber variable and different data types

    - by anubhav
    Hi, I am trying to parse a XML File using NSXMLParser, I also have a Container class, in which I have a few instance variables. One of the elements that I am trying to parse in the XML is: <book sn="32.859669048339128" pn="-116.917800670489670"> I am trying to save the value of sn and pn in an instance variable of object Container: NSNumber *sn, NSNumber *pn. I want it so that when my parser get the attributeValues it can save it as a Double (or float) in those NSNumber pointers. Right now, all it does it just saves a string to the NSNumber. The Parser Code looks like this: if([elementName isEqualToString:@"book"]){ container = [[Container alloc] init]; container.sn=[attributeDict objectForKey:@"sn"]; container.pn=[attributeDict objectForKey:@"pn"]; } I want it so that the type of container.sn is initialized to a float or double. Any ideas how to do this? Thanks in advance!

  • iphone: UIwebview curl effect

    - by eshalev
    Hello, I would like to make a standard view container which will give me the curl animation effect on multiple views. Something like uiscrollview and paging, only with a different animation(curl). I will be using UIwebviews as my separate pages. The problem: I do not know how to trap swipes in UIwebviews, But I see that UIscrollview implments this (swiping a uiwebview in a uiscrollview will bring me to the next view). I am therefore assuming that the implmentation of UIscrollview is trapping UIwebview swipes. How can i achieve the same functionality? I also need the UIWebview to keep functioning (as when embedding it in a uiscrollview)

  • iPhone hitTest broken after rotation

    - by Adam
    Hi all, I have a UIView that contains a number of CALayer subclasses. I am using the following code to detect which layer a touch event corresponds to: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint touchPoint = [touch locationInView:self]; NSLog(@"%@,%@",NSStringFromCGPoint(point),[self.layer hitTest:point].name); } This works fine until the device is rotated. When the device is rotated all current layers are removed from the superlayer, and new CALayers are created to fit the new orientation. The new layers are correctly inserted and viewable in the correct orientation. After the rotation the hitTest method consistently returns nil when clearly clicking on the newly created layers and registers for locations of layers which are incorrect. The coordinates of the hit test are correct, but no layers are found. Am I missing a function call or something after handling the rotation? Cheers, Adam

    I want to change the sprite image. Say for example. mainSprite=[Sprite spriteWithFile:@"redFile.png"]; [self addChild:mainSprite]; Here, Sprite is already added to a layer. I have mainSprite (pointer) which can access it. If I change [mainSprite setOpacity:150]; it works perfectly. But Here I want to change the sprite image instead of opacity. But Don't know how? Thanks in advance for helping me. Sagar

  • iPhone - Web Access Authentication

    - by Terry
    I am building a secure app for our exec's... here is my setup. It's a somewhat Macgyver approach, but bear with me :) There are only 10 users, I have a record of each uniqueIdentifier on my backend in a database table. (This is internal only for our users, so I don't believe I am breaking the public user registration rule mentioned in the API docs) Through adhoc distribution I install my app on all 10 devices My app is simply composed of a UIWebView. When the app starts it does a POST to our https site sending the uniqueIdentifier. (Thanks to this answer) The server page that recieves the POST, checks the uniqueIdentifier and if found sets a session cookie that automatically logs them into the site. This way the user doesn't have to enter in their credentials every time. So what do you think, is there a security hole with this? Thanks

  • Objective-C (iPhone) Memory Management

    - by Steven
    I'm sorry to ask such a simple question, but it's a specific question I've not been able to find an answer for. I'm not a native objective-c programmer, so I apologise if I use any C# terms! If I define an object in test.h @interface test : something { NSString *_testString; } Then initialise it in test.m -(id)init { _testString = [[NSString alloc] initWithString:@"hello"]; } Then I understand that I would release it in dealloc, as every init should have a release -(void)dealloc { [_testString release]; } However, what I need clarification on is what happens if in init, I use one of the shortcut methods for object creation, do I still release it in dealloc? Doesn't this break the "one release for one init" rule? e.g. -(id)init { _testString = [NSString stringWithString:@"hello"]; } Thanks for your helps, and if this has been answered somewhere else, I apologise!!

  • Iphone: UIWebview and double taps

    - by Eyal
    I would like to trap a double tap event in a UIWebView. I have derived a class from UIWebController. When I double tap it seams that the UIWebController itself is responding to my double taps instead of my class. The weird thing is that when I change the inheritance to inherit from UIView everything works just fine. Below are snippets from my code which is supposed to invoke a pop-up when double tapped. In the init function: //Setup action for double tap UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; tap.numberOfTapsRequired = 2; [super addGestureRecognizer:tap]; [tap release]; And Also: - (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer { UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Network error" message: @"Hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; //[[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_FLIP_TO_PAGE_VIEW object:nil]; }

  • FBConnect for iPhone: sessionDidNotLogin, sessionDidLogout, session didLogin not called the second t

    - by Irene
    My problem is very similar to this question, however I am posting a new one, as the answer to the aforementioned does not seem to solve my problem. I have a multiview application - the first view is where the user logs in to Facebook, and the second where he picks an image and uploads it there. The first time the app runs, everything works fine, however if I return to the login view and press logout, then any calls to sessionDidNotLogin, sessionDidLogout or session didLogin don't seem to work. I found out that the first time, if I NSLog(@"%@",session.delegates); I have 2; my LoginViewController and the FBLoginButton. However, apart from that first time, the same log prints only the LoginViewController and not the FBLoginButton. I guess this is connected somehow, but I don't know how to solve it. Do I have to manually add the FBLoginButton to the session delegates, or I'm doing something else wrong here? Thank you for any help/suggestion.

However, I want the display to show 10:59, 10:58, etc. until it reaches zero. How do I do this? Thanks!

  • iPhone app with tab bar and navigation bar as peers

    - by Mac
    I'm trying to write an application that uses a navigation bar and tab bar in what (I'm gathering) is an unusual manner. Basically, I've got several "pages" ("home", "settings", etc) that each have their own tab. I'd also like to have it so that the "home" page is the root view of the navigation bar, and the other pages are the second-level views of the navigation bar. That is, I should be able to navigate to any page by clicking the appropriate tab bar item, and should be able to navigate to the home page from any other page by clicking the navigation bar's back button. Currently, I have a UINavigationBar (through a UINavigationController) and a UITabBar (through a UITabController) as children of a UIView. The various pages' view controllers are set as the tab controller's viewControllers property, and the home page's controller is also set as the navigation controller's root view. Each page view's tag is set to its index in the tab control. I have the following logic in the tab controller's didSelectViewController delegate method: - (void) tabBarController:(UITabBarController*) tabBarController didSelectViewController:(UIViewController*) viewController { if ([navController.viewControllers count] > 1) [navController popViewControllerAnimated:NO]; [navController pushViewController:viewController animated:YES]; } Also, in the navigation controller's didShowViewController delegate method, I have the following code: - (void) navigationController:(UINavigationController *) navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated { tabController.selectedIndex = viewController.view.tag; } The problem that's occurring is that when I run this, the navigation bar, tab bar and home page all display ok, but the tab bar will not respond to input - I cannot select a different tab. I gather it's more usual to have the tab bar as the child of the navigation control, or vice versa. This doesn't seem to fit my approach, because I don't want to have to individually create the subordinate control each time a change occurs in the parent control - eg: recreate tab bar each time the navigation bar changes. Does anyone have suggestions as to what's wrong and how to fix it? I'm probably missing something obvious, but whatever it is I can't seem to find it. Thanks! EDIT: I'm guessing it has something to do with both controller's trying to have ownership of the page controller, but I can't for the life of me figure out a way around it.
