  • How do I redirect within a ViewResult or ActionResult function?

    - by Pete
    Say I have: public ViewResult List() {} inside this function, I check if there is only one item in the list, if there is I'd like to redirect straight to the controller that handles the list item, otherwise I want to display the List View. How do I do this? Simply adding a RedirectToAction doesn't work - the call is hit but VS just steps over it and tries to return the View at the bottom.

  • Strange crashes when using MPMoviePlayerController in iPad and iPad simulator with iOS 4.2.

    - by Dave L
    I'm getting crashes when trying to play a movie using MPMoviePlayerController on the iPad and in the iPad simulator using iOS 4.2. I am building using xcode 3.2.5 and the 4.2 SDK. When running on an iPad using iOS 3.2 or in the iPad simulator 3.2, the same code works fine, but on an iPad running 4.2 or in the iPad simulator 4.2, it crashes. The crash is due to an exception for calling an unknown selector down somewhere deep in the cocoa libraries, something tries to call a selector called "setHitRectInsets:" on a UIButton object. Also, the crash happens after control has returned to the main event loop. Anybody have any idea what might be causing this? Here is the code (roughly, some extraneous stuff deleted that doesn't seem to have any effect) that is crashing: NSString *fullMovieFilename = [[NSBundle mainBundle] pathForResource:@"movie" ofType:@"m4v"]; NSURL *movieURL = [NSURL fileURLWithPath:fullMovieFilename]; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; moviePlayer.controlStyle = MPMovieControlStyleNone; // crash happens regardless of the setting here [moviePlayer.view setFrame:self.view.bounds]; [self.view addSubview:moviePlayer.view]; [moviePlayer setFullscreen:YES animated:YES]; // crash happens whether i use fullscreen or not [moviePlayer play]; The same code also works just find if I build using Xcode 3.2.3 and the 4.0 SDK. The crash stack trace looks like this: 2011-03-04 23:08:22.017 MyApp[31610:207] -[UIButton setHitRectInsets:]: unrecognized selector sent to instance 0x990bc60 2011-03-04 23:08:22.020 MyApp[31610:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIButton setHitRectInsets:]: unrecognized selector sent to instance 0x990bc60' *** Call stack at first throw: ( 0 CoreFoundation 0x0151abe9 __exceptionPreprocess + 185 1 libobjc.A.dylib 0x0166f5c2 objc_exception_throw + 47 2 CoreFoundation 0x0151c6fb -[NSObject(NSObject) doesNotRecognizeSelector:] + 187 3 CoreFoundation 0x0148c366 ___forwarding___ + 966 4 CoreFoundation 0x0148bf22 _CF_forwarding_prep_0 + 50 5 MediaPlayer 0x011b5bdb -[MPTransportControls createButtonForPart:] + 380 6 MediaPlayer 0x011b65d5 -[MPTransportControls _updateAdditions:removals:forPart:] + 110 7 MediaPlayer 0x011b4d78 -[MPTransportControls _reloadViewWithAnimation:] + 299 8 MediaPlayer 0x011b621a -[MPTransportControls setVisibleParts:] + 49 9 MediaPlayer 0x011b6e4a -[MPTransportControls initWithFrame:] + 173 10 MediaPlayer 0x011f9188 -[MPInlineTransportControls initWithFrame:] + 78 11 MediaPlayer 0x011f193a -[MPInlineVideoOverlay layoutSubviews] + 158 12 QuartzCore 0x00d6e451 -[CALayer layoutSublayers] + 181 13 QuartzCore 0x00d6e17c CALayerLayoutIfNeeded + 220 14 QuartzCore 0x00d6e088 -[CALayer layoutIfNeeded] + 111 15 MediaPlayer 0x011f130c -[MPInlineVideoOverlay setAllowsWirelessPlayback:] + 46 16 MediaPlayer 0x011f5b0d -[MPInlineVideoViewController _overlayView] + 526 17 MediaPlayer 0x011f6359 -[MPInlineVideoViewController _layoutForItemTypeAvailable] + 1350 18 Foundation 0x000e56c1 _nsnote_callback + 145 19 CoreFoundation 0x014f2f99 __CFXNotificationPost_old + 745 20 CoreFoundation 0x0147233a _CFXNotificationPostNotification + 186 21 Foundation 0x000db266 -[NSNotificationCenter postNotificationName:object:userInfo:] + 134 22 Foundation 0x000e75a9 -[NSNotificationCenter postNotificationName:object:] + 56 23 MediaPlayer 0x01184dd6 -[MPAVItem _updateForNaturalSizeChange] + 278 24 MediaPlayer 0x011818e4 __-[MPAVItem blockForDirectAVControllerNotificationReferencingItem:]_block_invoke_1 + 82 25 MediaPlayer 0x011899ba -[MPAVController _postMPAVControllerSizeDidChangeNotificationWithItem:] + 138 26 Foundation 0x000e56c1 _nsnote_callback + 145 27 CoreFoundation 0x014f2f99 __CFXNotificationPost_old + 745 28 CoreFoundation 0x0147233a _CFXNotificationPostNotification + 186 29 Foundation 0x000db266 -[NSNotificationCenter postNotificationName:object:userInfo:] + 134 30 Celestial 0x052a35b2 -[NSObject(NSObject_AVShared) postNotificationWithDescription:] + 176 31 Celestial 0x052ab214 -[AVController fpItemNotification:sender:] + 735 32 Celestial 0x052b5305 -[AVPlaybackItem fpItemNotificationInfo:] + 640 33 Celestial 0x052a3d5c -[AVObjectRegistry safeInvokeWithDescription:] + 211 34 Foundation 0x000fa9a6 __NSThreadPerformPerform + 251 35 CoreFoundation 0x014fc01f __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 15 36 CoreFoundation 0x0145a28b __CFRunLoopDoSources0 + 571 37 CoreFoundation 0x01459786 __CFRunLoopRun + 470 38 CoreFoundation 0x01459240 CFRunLoopRunSpecific + 208 39 CoreFoundation 0x01459161 CFRunLoopRunInMode + 97 40 GraphicsServices 0x01e4f268 GSEventRunModal + 217 41 GraphicsServices 0x01e4f32d GSEventRun + 115 42 UIKit 0x0038a42e UIApplicationMain + 1160 43 MyApp 0x0000837a main + 102 44 MpApp 0x00002009 start + 53 ) terminate called after throwing an instance of 'NSException' Been fighting with this for several days, and have searched the internet quite a bit for anybody having similar problems, all with no luck.

  • surfaceview + glsurfaceview + framelayout

    - by pohtzeyun
    Hi, I'm new at this (java and opengl) so please bear with me if the answer to the question is simple. :) I'm trying to get a camera preview screen with the ability to display 3d objects simultaneously. Having gone through the samples at the api demos, I thought combining the code for the the examples at the api demo would suffice. But somehow its not working. The forces me to shut down upon startup and the error is mentioned as null pointer exception. Could someone share with me where did I go wrong and how to proceed from there. How I did the combination for the code is as shown below: myoverview.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <android.opengl.GLSurfaceView android:id="@+id/cubes" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <SurfaceView android:id="@+id/camera" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </FrameLayout> myoverview.java import android.app.Activity; import android.os.Bundle; import android.view.SurfaceView; import android.view.Window; public class MyOverView extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // camera view as the background SurfaceView cameraView = (SurfaceView) findViewById(R.id.camera); cameraView = new CameraView(this); // visual of both cubes GLSurfaceView cubesView = (GLSurfaceView) findViewById(R.id.cubes); cubesView = new GLSurfaceView(this); cubesView.setRenderer(new CubeRenderer(false)); // set view setContentView(R.layout.myoverview); } } GLSurfaceView.java import android.content.Context; class GLSurfaceView extends android.opengl.GLSurfaceView { public GLSurfaceView(Context context) { super(context); } } NOTE : I didnt list the rest of the files as they are just copies of the api demos. The cameraView refers to the camerapreview.java example and the CubeRenderer refers to the CubeRenderer.java and Cube.java example. Any help would be appreciated as I've been stuck at this for a couple of days :p Thanks Sorry, didnt realise that the coding was out of place due to formatting mistakes. :p

  • Android strange behavior with listview and custom cursor adapter

    - by Michael Little
    I have a problem with a list view and a custom cursor adapter and I just can't seem to figure out what is wrong with my code. Basically, in my activity I call initalize() that does a bunch of stuff to handle getting the proper data and initializing the listview. On first run of the activity you can see from the images that one of the items is missing from the list. If I go to another activity and go back to this activity the item that was missing shows up. I believe it has something to do with setContentView(R.layout.parent). If I move that to my initialize() then the item never shows up even when returning from another activity. So, for some reason, returning from another activity bypasses setContentView(R.layout.parent) and everything works fine. I know it's impossible for me to bypass setContentView(R.layout.parent) so I need to figure out what the problem is. Also, I did not include the layout because it is nothing more then two textviews. Also, the images I have attached do not show that the missing item is the last one on the list. Custom Cursor Adapter: public class CustomCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public CustomCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(context); final View view = inflater.inflate(layout, parent, false); return view; } @Override public void bindView(View v, Context context, Cursor c) { if (c.getColumnName(0).matches("section")){ int nameCol = c.getColumnIndex("section"); String section = c.getString(nameCol); TextView section_text = (TextView) v.findViewById(R.id.text1); if ((section.length() > 0)) { section_text.setText(section); } else { //so we don't have an empty spot section_text.setText(""); section_text.setVisibility(2); section_text.setHeight(1); } } else if (c.getColumnName(0).matches("code")) { int nameCol = c.getColumnIndex("code"); String mCode = c.getString(nameCol); TextView code_text = (TextView) v.findViewById(R.id.text1); if (code_text != null) { int i = 167; byte[] data = {(byte) i}; String strSymbol = EncodingUtils.getString(data, "windows-1252"); mCode = strSymbol + " " + mCode; code_text.setText(mCode); code_text.setSingleLine(); } } if (c.getColumnName(1).matches("title")){ int nameCol = c.getColumnIndex("title"); String mTitle = c.getString(nameCol); TextView title_text = (TextView) v.findViewById(R.id.text2); if (title_text != null) { title_text.setText(mTitle); } } else if (c.getColumnName(1).matches("excerpt")) { int nameCol = c.getColumnIndex("excerpt"); String mExcerpt = c.getString(nameCol); TextView excerpt_text = (TextView) v.findViewById(R.id.text2);

  • ASP.NET - FileUpload with PostBack Trigger

    I have an UpdatePanel which has an upload control and a button to upload. The button is set as a trigger, but the event handler for the button fails to execute on the first PostBack. My ASPX code is: <asp:UpdatePanel ID="updPages" runat="server" UpdateMode="Conditional"> <ContentTemplate> <div class="tabs"> <ul> <li><asp:LinkButton ID="lnkContentsPages" runat="server" OnClick="updateContents" CommandArgument="pages">Pages</asp:LinkButton></li> <%-- these tabs change the ActiveViewIndex to show a different UserControl --%> <li><asp:LinkButton ID="lnkContentsImages" runat="server" OnClick="updateContents" CommandArgument="images">Images</asp:LinkButton></li> </ul> <div class="tabbedContent"> <asp:MultiView runat="server" ID="mltContentsInner" ActiveViewIndex="0"> <asp:View ID="viwContentsImages" runat="server"> // ajax usercontrol for a list of images - works fine with ajax <fieldset> <legend>Upload New</legend> <div class="formRow"> <asp:Label ID="lblFile" runat="server" Text="Filename" AssociatedControlID="uplFile" /> <asp:FileUpload ID="uplFile" runat="server" /> </div> <div class="formRow"> <asp:Label ID="lblImageDescription" runat="server" Text="Description" AssociatedControlID="txtImageDescription" /> <asp:TextBox runat="server" ID="txtImageDescription" /> </div> <asp:Button ID="btnUpload" runat="server" Text="Upload" CssClass="c3button btnUpload" CausesValidation="false" OnClick="btnUpload_Click" /> </fieldset> </asp:View> <asp:View ID="viwContentsPages" runat="server"> // ajax usercontrol - works fine with ajax </asp:View> </asp:MultiView> </div> </div> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="btnUpload" /> </Triggers> </asp:UpdatePanel> The button works without fail on the second and subsequent times, just not the first.

  • dublicate display of Posts from controller - conditions and joins problem - Ruby on Rails

    - by bgadoci
    I have built a blog application using Ruby on Rails. In the application I have posts and tags. Post has_many :tags and Tag belongs_to :post. In the /views/posts/index.html view I want to display two things. First is a listing of all posts displayed 'created_at DESC' and then in the side bar I am wanting to reference my Tags table, group records, and display as a link that allows for viewing all posts with that tag. With the code below, I am able to display the tag groups and succesfully display all posts with that tag. There are two problems with it thought. /posts view, the code seems to be referencing the Tag table and displaying the post multiple times, directly correlated to how many tags that post has. (i.e. if the post has 3 tags it will display the post 3 times). /posts view, only displays posts that have Tags. If the post doesn't have a tag, no display at all. /views/posts/index.html.erb <%= render :partial => @posts %> /views/posts/_post.html.erb <% div_for post do %> <h2><%= link_to_unless_current h(post.title), post %></h2> <i>Posted <%= time_ago_in_words(post.created_at) %></i> ago <%= simple_format h truncate(post.body, :length => 300) %> <%= link_to "Read More", post %> | <%= link_to "View & Add Comments (#{post.comments.count})", post %> <hr/> <% end %> /models/post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy cattr_reader :per_page @@per_page = 10 end posts_controller.rb def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts=Post.all(:joins => :tags,:conditions=>(params[:tag_name] ? { :tags => { :tag_name => params[:tag_name] }} : {} ) ).paginate :page => params[:page], :per_page => 5 respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end

  • UITabBarController rotation problem with popViewControllerAnimated and selectedIndex (iPhone SDK)

    - by rjobidon
    Hi! This is a very important auto rotate issue and easy to reproduce. My application has a UITabBarController. Each tab is a UINavigationController. Auto rotation is handled with normal calls to shouldAutorotateToInterfaceOrientation and didRotateFromInterfaceOrientation. The interface rotates normally until I call UIViewController.popViewControllerAnimated and change UITabBarController.selectedIndex. Steps to reproduce: Create a demo Tab Bar Application. Add the following code to the App Delegate .h file: #import <UIKit/UIKit.h> @interface TestRotationAppDelegate : NSObject { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; -(void)doAction; @end // Redefine the interface to cach rotation messages @interface UITabBarController (TestRotation1AppDelegate) @end Add the following code to the App Delegate .m file: #import "TestRotationAppDelegate.h" @implementation TestRotationAppDelegate @synthesize window; @synthesize tabBarController; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; return YES; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } -(void)dealloc { [tabBarController release]; [window release]; [super dealloc]; } @end @implementation UITabBarController (TestRotation1AppDelegate) -(void)viewDidLoad { [super viewDidLoad]; // Add a third tab and push a view UIViewController *view1 = [[UIViewController alloc] init]; view1.title = @"Third"; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:view1]; NSMutableArray *array = [[NSMutableArray alloc] init]; [array addObjectsFromArray:self.viewControllers]; [array addObject:nav]; self.viewControllers = array; // Push view2 inside the third tab UIViewController *view2 = [[UIViewController alloc] init]; [nav pushViewController:view2 animated:YES]; // Create a button to pop view2 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 50, 220, 38); [button setTitle:@"Pop this view" forState:UIControlStateNormal]; [button addTarget:self action:@selector(doAction) forControlEvents:UIControlEventTouchUpInside]; [view2.view addSubview:button]; } -(void) doAction { // ROTATION PROBLEM BEGINS HERE // Remove one line of code and the problem doesn't occur. [self.selectedViewController popViewControllerAnimated:YES]; self.selectedIndex = 0; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end The interface auto rotates normally until you tap the button on tab #3. Your help will be geatly appreciated!

  • iPhone SDK can't get UIScrollView to work with a UIWebView

    - by Maxwell Segal
    I am building an app that in part of it has two views - one portrait and one landscape. And I want to offer scrolling and pinch & zooming on the landscape orientation. I've built the two views and the simple UIImages in the landscape view all work OK but it does not seem to insert my UIWebView into the UIScrollView. I've done this before with UIImage and all was OK but I must be missing something here - can anybody help with some advice. I'm sure it's something very simple - perhaps to do with the adding of the subview??. Thanks in advance of your help.

    - by Amit Jain
    Hi I am having to picker controls on a single view with two outlets for each. Now when I select any of them same delegate methods are get called. How should we distinguish between which picker control has called the delegate ? Another question is can we change the frame size of the pickers to fit in one view? Thanks Amit

  • UIModalTransitionStylePartialCurl not rotating

    - by Mongo
    I've got a modal view controller that is being displayed using UIModalPresentationFullScreen with the TransitionStyle set as UIModalTransitionStylePartialCurl. This works beautifully. My problem is that when the device is rotated, my view rotates (as intended), but the "curl" effect does not. Does anyone know if this is by design, or is there something else that needs to be done? Thanks.

  • Why does my UIActivityIndicatorView only display once?

    - by Schwigg
    I'm developing an iPhone app that features a tab-bar based navigation with five tabs. Each tab contains a UITableView whose data is retrieved remotely. Ideally, I would like to use a single UIActivityIndicatorView (a subview of the window) that is started/stopped during this remote retrieval - once per tab. Here's how I set up the spinner in the AppDelegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { [window addSubview:rootController.view]; activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [activityIndicator setCenter:CGPointMake(160, 200)]; [window addSubview:activityIndicator]; [window makeKeyAndVisible]; } Since my tabs were all performing a similiar function, I created a base class that all of my tabs' ViewControllers inherit from. Here is the method I'm using to do the remote retrieval: - (void)parseXMLFileAtURL:(NSString *)URL { NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init]; AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"parseXMLFileAtURL started."); [appDelegate.activityIndicator startAnimating]; NSLog(@"appDelegate.activityIndicator: %@", appDelegate.activityIndicator); articles = [[NSMutableArray alloc] init]; NSURL *xmlURL = [NSURL URLWithString:URL]; rssParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; [rssParser setDelegate:self]; [rssParser setShouldProcessNamespaces:NO]; [rssParser setShouldReportNamespacePrefixes:NO]; [rssParser setShouldResolveExternalEntities:NO]; [rssParser parse]; NSLog(@"parseXMLFileAtURL finished."); [appDelegate.activityIndicator stopAnimating]; [apool release]; } This method is being called by each view controller as follows: - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if ([articles count] == 0) { NSString *path = @"http://www.myproject.com/rss1.xml"; [self performSelectorInBackground:@selector(parseXMLFileAtURL:) withObject:path]; } } This works great while the application loads the first tab's content. I'm presented with the empty table and the spinner. As soon as the content loads, the spinner goes away. Strangely, when I click the second tab, the NSLog messages from the -parseXMLFileAtURL: method show up in the log, but the screen hangs on the first tab's view and I do not see the spinner. As soon as the content is done downloading, the second tab's view appears. I suspect this has something to do with threading, with which I'm still becoming acquainted. Am I doing something obviously wrong here?

  • Animating custom-drawn UITableViewCell when entering edit mode

    - by Adam Alexander
    Background First of all, much gratitude to atebits for their very informative blog post Fast Scrolling in Tweetie with UITableView. The post explains in detail how the developers were able to squeeze as much scrolling performance as possible out of the UITableViews in Tweetie. Goals Beginning with the source code linked from the blog post (original) (my github repo): Allow a UITableView using these custom cells to switch to edit mode, exposing the UI for deleting an item from the table. (github commit) Move the cell's text aside as the deletion control slides in from the left. This is complete, although the text jumps back and forth without animation. (github commit) Apply animation to the text movement in goal 2 above for a smooth user experience. This is the step where I became stuck. The Question What is the best way to introduce this animation to complete goal 3? It would be nice if this could be done in a manner that keeps the logic from my last commit because I would love the option to move the conflicting part of the view only, while any non-conflicting portions (such as right-justified text) stay in the same place or move a different number of pixels. If the above is not possible then undoing my last commit and replacing it with an option that slides the entire view to the right would be a workable solution also. I appreciate any help anyone can provide, from quick pointers and ideas all the way to code snippets or github commits. Of course you are welcome to fork my repo if you would like. I will be staying involved with this question to make sure any successful resolution is committed to github and fully documented here. Thanks very much for your time! Updated thoughts I have been thinking about this a lot since my first post and realized that moving some text items relative to others in the view could undo some of the original performance goals solved in the original blog post. So at this point I am thinking a solution where the entire single subview is animated to its new postion may be the best one. Second, if it is done in this way there may be an instance where the subview has a custom color or gradient background. Hopefully this can be done in a way that in its normal position the background extends unseen off to the left enough so that when the view is slid to the right the custom background is still visible across the entire cell.

  • How to set the title of UIToolBar?

    - by Kelvin
    How can I set the title of UIToolBar such that it looks the same as the title in UINavigationBar? I tried to use a button with plain style, it looks ok, but it will be highlighted when I click on it... Is there any better way to set the title in the detail view of split view?
