UIDocumentInteractionController remove Actions Menu - ios

I've been working with the Apple sample code for viewing documents from here:
https://developer.apple.com/library/ios/samplecode/DocInteraction/Listings/ReadMe_txt.html
I have removed all the bits I don't need and got it working pretty much how I would like it to. The problem is I don't want users to have access to the "Actions" menu on the top right of the Document Controller. This appears every time you select a document from the list:
Ideally I would like to remove the button all together, though if I could disable it or disable all the options inside it that would also suffice. I found this question:
Open in + UIDocumentInteractionController : how to filter options in SDK iOS 6 (canPerformActions is deprecated)
But I couldn't figure out how to use the suggestion to disable the options inside the menu. I have uploaded the modified sample code here:
http://plasma.servebeer.com/DocSampleCode.zip
One final note is this will not be going on the App Store it is for private, personal use, so if there is an unofficial way then I would be interested in knowing that too.
Any help would be greatly appreciated, thanks in advance.

Use UINavigationControllerDelegate
#interface DITableViewController () <UIDocumentInteractionControllerDelegate, UINavigationControllerDelegate>
Assign navigationController delegate to self
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationController.delegate = self;
}
Change documentInteractionControllerViewControllerForPreview
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)interactionController {
return self.navigationController;
}
Add this UINavigationControllerDelegate method
// Called when the navigation controller shows a new top view controller via a push, pop or setting of the view controller stack.
- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
if ([viewController isKindOfClass:[QLPreviewController class]]) {
viewController.navigationItem.rightBarButtonItem = nil;
}
}
Update for MP4 files
In MP4 files the action button is on the UIToolbar
- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
if ([viewController isKindOfClass:[QLPreviewController class]]) {
viewController.navigationItem.rightBarButtonItem.customView = [[UIView alloc] init];
UIBarButtonItem *item = viewController.toolbarItems.firstObject;
item.customView = [[UIView alloc] init];
}
}
N.B. This might not work in future versions of iOS

After creating QLPreviewController class you would need to set rightBarButtonItem to nil. Code snippet:
QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.navigationItem.rightBarButtonItem = nil;
I did download project and after execution "Action" button was shown not in the top navigation item, but in the toolbar. Then in this case you would need to subclass QLPreviewController and override viewWillAppear as shown below.
#implementation ExViewController
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
NSMutableArray *a = [NSMutableArray arrayWithArray:#[]];
for (NSUInteger i = 0; i < self.toolbarItems.count; i++) {
if (i == 0) {
continue;
}
[a addObject:self.toolbarItems[i]];
}
}
#end

If you want to hide button the give answers will not work for iOS 10.0 and above in Swift language. You can use WKWebView. Hope it will save your time.

App Shows Old XIB Instead of Storyboard

I'm updating an old iOS project that uses XIB files but want to convert to Storyboard. I created my Storyboard, connected it with the appropriate ViewControllers, removed any references that I can find to the XIB files, and set the Main Interface of the project to use my Storyboard.
However, when I run my app it still shows the XIB files instead of using the Storyboard; as if there's something still referencing them. The only one that shows the Storyboard is the initial scene/ViewController (and it's most likely because it's a newly created ViewController).
I've looked at other solutions online but to no avail. I tried:
Cleaning the project
Deleting DerivedData folder
Restarting Xcode and my computer
Updated MyApplication-info.plist
Removed references to ViewControllers from XIB files
Tried removing XIB files from project (it'll show a black screen because file is missing)
The original project target iOS 5.1, the new 6.0, and I'm using Xcode 5. Is there anything that I might be missing?
Edit: I'm not programmatically segueing to the other controllers; I have the Storyboard take care of that. The only thing I do in the first ViewController is send a string text to the next one:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NextViewController * nextController;
if ([[segue identifier] isEqualToString:#"SegueToNext"])
{
nextController = [segue destinationViewController];
[nextController initWithTitle:#"New"];
}
}
Edit: This is the code for the ViewController that is showing the XIB file instead of the Storyboard. As you can see, there are no calls related to loading/pushing new controllers or anything that should relate to the XIB.
#import "NextViewController.h"
#interface NextViewController ()
#end
#implementation NextViewController
-(id) initWithTitle:(NSString *) title
{
self = [super init];
if (self)
{
self.title = title;
// Load the dictionary
self.dictionary = [NSDictionary dictionaryWithContentsOfFile:
[[NSBundle mainBundle] pathForResource:#"NewDictionary"
ofType:#"plist"]];
}
return self;
}
-(void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// Render new slide
[self renderOpening];
}
-(void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
-(void) renderOpening
{
// 1st slide
NSLog(#"renderOpening");
// Initial settings for opening slide; all are UIOutlets (UIButton, UIImageView)
back.hidden = YES;
diagram.hidden = YES;
next.hidden = NO;
text.hidden = NO;
avatar.hidden = NO;
avatar.image = [[UIImage imageNamed:#"avatar"]
rescaleImageToSize:CGSizeMake(150, 150)];
text.text = #"Hello World";
}
#end
Within your appDelegate class file, remove any code that directs the app to launch to your old initial xib. (From within the didFinishLaunching' method) You don't need to replace it with any code to start the storyboard as this selects this from the 'Development Info' section - see below.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
Then click on your project and under the tab of 'General' within the 'Development Info' section, make sure your storyboard is selected as the main interface - see picture below.
Also, if you select the view controller from the storyboard that you want the app to initially start with and select it. Then go to the RHS utilities area and make sure the 'Initial Scene [ ] Is Initial View Controller bock is selected, please see picture.
I hope this helps,
Cheers

In the ViewController that I was segueing to, I called a custom function which returned a reference to a newly created object of the ViewController class itself:
-(id) initWithTitle:(NSString *) title
{
self = [super init];
if (self)
{
self.title = title;
// Load the dictionary
self.dictionary = [NSDictionary dictionaryWithContentsOfFile:
[[NSBundle mainBundle] pathForResource:#"NewDictionary"
ofType:#"plist"]];
}
return self;
}
It was left there from the old code, and I completely overlooked it. It was no longer needed now that I was using Storyboard. So instead of seeing the ViewController that I was segueing into, it was showing the old XIB file. Deleting the XIB file from the project showed an empty, black view, and removing the code [super init] showed the correct Storyboard ViewController.
Although I got it working, I'm still not certain as to why it was showing the old XIB file, even though I removed references to it.

Drag and drop from Collectionview into ContactViewController doesn't work on iPad

I'm developing an app which uses splitView.
I'm using two items in splitView (Called them Customer and Supplier).
When I click on one of them I just use one viewController to display (called it: ContactViewController) and I use collectionView to display its data. To get data I just code it:
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
if (!dbManager.synchronized) {
if (contactType == ContactTypeCustomer)
[dbManager requestData:kDbCustomers predicate:nil target:self];
else if (contactType == ContactTypeSuppplier)
[dbManager requestData:kDbSuppliers predicate:nil target:self];
}
}
And when get successful:
#pragma mark
#pragma DBDelegate
- (void)requestDataCompleted:(NSMutableArray *)results
{
datasource = results;
[self.collectionView reloadData];
}
I use I3DragBetweenHelper downloaded from github.com
Embedded into my app to initial drag and drop. To do this, I call the below method into viewDidLoad of ContactViewController
- (void) initDragAndDrop
{
self.helper = [[I3DragBetweenHelper alloc] initWithSuperview:self.view
srcView:_collectionView
dstView:_collectionView];
self.helper.delegate = self;
self.helper.isDstRearrangeable = NO;
self.helper.isSrcRearrangeable = NO;
self.helper.doesSrcRecieveDst = NO;
self.helper.doesDstRecieveSrc = YES;
self.helper.hideDstDraggingCell = YES;
self.helper.hideSrcDraggingCell = NO;
}
The helper here is:
#property (strong, nonatomic) I3DragBetweenHelper *helper;
The problem is when I click on Supplier I can drag and drop the cell of collectionView into ContactViewController. Below method had called and worked:
- (BOOL)droppedOutsideAtPoint:(CGPoint)pointIn fromDstIndexPath:(NSIndexPath *)from
But when I click on Customer the above method doesn't call. I can't even drag my cell of collectionView into ContactViewController. Any help will appreciate.
Why is isDstRearrangeable set to NO ??? coz eventually you would grab something and drop it onto something ( dest ) and that something ( dest ) will be rearranged, am i wrong ??
does your drag and drop happen in the same place ?? ( i.e: UICollectionView )
if it does, then why do you have src as not rearrangeable ??? both your destination and src should be rearrangeable.
Try this and let me know how it goes :)
I dont know about this library but I think the problem is your srcView and dstView are the same. These should be different and must be either UITableView or UICollectionView.
If you are using UISplitViewController, its probably going to be the Master and Detail View Controllers used by the UISplitView

Passing Data from Slide menu to UITableViewController through UINavigationViewController

How can I pass data from UINavigationController to The root UITableViewController?
I have implemented the ECSlidingViewController (https://github.com/edgecase/ECSlidingViewController). User selects one of the cells in the menu that correspond to different urls I want to display information from on my tableView that sitts on top of the UINavigationController. (u know the default combination that u get my dragging UINavigationController to ur storyboard). I am able to get the data from the sliding menu to my navigationController now I am trying to pass that same info on my tableview?
In my menu I have:
UINavigationController *newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"NavigationTop"];
newTopViewController = [(NavigationTopViewController*)newTopViewController initWithCinema:self.myCinema];
In UINaviationController:
- (id)initWithCinema:(Cinema *)cinema {
self = [super init];
if(self) {
_myCinema = [[Cinema alloc] init];
_myCinema = cinema;
}
return self;
}
- (void) viewDidLoad {
[super viewDidLoad];
// this log works I get the info to here.
NSLog(#"url(navigation):%#", self.myCinema.cinemaURL);
//MoviesTableViewController *moviesTableViewController = [[MoviesTableViewController alloc] initWithCinema:self.myCinema];
//UITableViewController *newTopViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"MoviesTable"];
//NavigationTopViewController *newTopViewController = [[NavigationTopViewController alloc] initWithCinema:self.myCinema];
//newTopViewController = [(MoviesTableViewController *)newTopViewController initWithCinema:self.myCinema];
//[self performSegueWithIdentifier:nil sender:self.myCinema];
[self prepareForSegue:nil sender:self.myCinema.cinemaURL];
}
In my UITableView:
- (void)setCinema:(Cinema *)cinema {
// works here too
NSLog(#"Table(setCinema):%#", cinema.cinemaURL);
self.myCinema = [[Cinema alloc] init];
if(!cinema) {
cinema.cityIndex = kAstanaIndex;
cinema.name = kKeruen;
cinema.nameForText = kKeruenText;
cinema.cinemaURL = kKeruenURL;
cinema.cinemaURLTomorrow = kKeruenURLtomorrow;
}
self.myCinema = cinema;
// works here too!!!
NSLog(#"Table(myCinema):%#", self.myCinema.cinemaURL);
}
However its gone in viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
// set delegate to self
self.tableView.delegate = self;
// set loading theater's url
// does not work here: I GET NULL !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
NSLog(#"url(moviesTable):%#", self.myCinema.cinemaURL);
_model = [[MovieModel alloc] initWithURL:self.myCinema.cinemaURL];
}
None of the methods I have tried (commented in Navigation worked...) at least for me. Please give me any suggestions. Thank you in advance.
UINavigationController does not hold any data, but rather a stack of view controllers. I'd recommend you check out frameworks such as the free Sensible TableView. The framework will automatically handle detail view generation and passing data between them. Saves me tons of development time in my projects.

UITableView headings shown on top of MBProgressHUD

So I have a subclass of UITableViewController that loads some data from the internet and uses MBProgressHUD during the loading process. I use the standard MBProgressHUD initialization.
HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];
HUD.delegate = self;
HUD.labelText = #"Loading";
[HUD show:YES];
This is the result:
.
Is there any way to resolve this issue, or should I just abandon MBProgressHUD?
Thanks!
My solution was pretty simple. Instead of using self's view, I used self's navigationController's view.
HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
[self.navigationController.view addSubview:HUD];
This should work for the OP because his picture shows he's using a UINavigationController. If you don't have a UINavigationController, you might add another view on top of your UITableView, and add the HUD to that. You'll have to write a little extra code to hide/show this extra view.
An unfortunate thing with this simple solution (not counting my idea adding another view mentioned above) means the user can't use the navigation controls while the HUD is showing. For my app, it's not a problem. But if you have a long running operation and the user might want to press Cancel, this will not be a good solution.
It's probably because self.view is a UITableView, which may dynamically add/remove subviews including the headers, which could end up on top of the HUD after you add it as a subview. You should either add the HUD directly to the window, or (for a little more work but perhaps a better result) you could implement a UIViewController subclass which has a plain view containing both the table view and the HUD view. That way you could put the HUD completely on top of the table view.
My solution was:
self.appDelegate = (kmAppDelegate *)[[UIApplication sharedApplication] delegate];
.
.
_progressHUD = [[MBProgressHUD alloc] initWithView:self.appDelegate.window];
.
[self.appDelegate.window addSubview:_progressHUD];
Works like a charm for all scenarios involving the UITableViewController. I hope this helps someone else. Happy Programming :)
Create a category on UITableView that will take your MBProgressHUD and bring it to the front, by doing so it will always appear "on top" and let the user use other controls in your app like a back button if the action is taking to long (for example)
#import "UITableView+MBProgressView.h"
#implementation UITableView (MBProgressView)
- (void)didAddSubview:(UIView *)subview{
for (UIView *view in self.subviews){
if([view isKindOfClass:[MBProgressHUD class]]){
[self bringSubviewToFront:view];
break;
}
}
}
#end
A simple fix would be to give the z-index of the HUD view a large value, ensuring it is placed in front of all the other subviews.
Check out this answer for information on how to edit a UIView's z-index: https://stackoverflow.com/a/4631895/1766720.
I've stepped into a similar problem a few minutes ago and was able to solve it after being pointed to the right direction in a different (and IMHO more elegant) way:
Add the following line at the beginning of your UITableViewController subclass implementation:
#synthesize tableView;
Add the following code to the beginning of your init method of your UITableViewController subclass, like initWithNibName:bundle: (the beginning of viewDidLoad might work as well, although I recommend an init method):
if (!tableView &&
[self.view isKindOfClass:[UITableView class]]) {
tableView = (UITableView *)self.view;
}
self.view = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
self.tableView.frame = self.view.bounds;
self.tableView.contentInset = UIEdgeInsetsMake(0.0, 0.0, 0.0, 0.0);
[self.view addSubview:self.tableView];
Then you don't need to change your code you posted in your question any more. What the above code does is basically seperating the self.tableView from self.view (which was a reference to the same object as self.tableView before, but now is a UIView containing the table view as one might expect).
I've Just solved that issue manually , it has been 2 years since Chris Ballinger asked but maybe someone get used of what is going on here.
In UITableViewController i execute an HTTP method in viewDidLoad , which is running in background so the table view is loaded while the progress is shown causing that miss.
i added a false flag which is changed to yes in viewDidLoad, And in viewDidAppear something like that can solve that problem.
-(void) viewDidAppear:(BOOL)animated{
if (flag) {
[self requestSomeData];
}
flag = YES;
[super viewDidAppear:animated];
}
I had the same problem and decided to solve this by changing my UITableViewController to a plain UIViewController that has a UITableView as a subview (similar to what jtbandes proposed as an alternative approach in his accepted answer). The advantage of this solution is that the UI of the navigation controller isn't blocked, i.e. users can simply leave the ViewController in case they don't want to waiting any longer for your timely operation to finish.
You need to do the following changes:
Header file:
#interface YourViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
- (id)initWithStyle:(UITableViewStyle)style;
#end
Implementation file:
#interface YourViewController ()
#property (nonatomic, retain) UITableView *tableView;
#property (nonatomic, retain) MBProgressHUD *hud;
#end
#implementation YourViewController
#pragma mark -
#pragma mark Initialization & Memory Management
- (id)initWithStyle:(UITableViewStyle)style;
{
self = [super init];
if (self) {
// create and configure the table view
_tableView = [[UITableView alloc] initWithFrame:CGRectNull style:style];
_tableView.delegate = self;
_tableView.dataSource = self;
}
return self;
}
- (void)dealloc
{
self.tableView = nil;
self.hud = nil;
[super dealloc];
}
#pragma mark -
#pragma mark View lifecycle
- (void)loadView {
CGRect frame = [self boundsFittingAvailableScreenSpace];
self.view = [[[UIView alloc] initWithFrame:frame] autorelease];
// add UI elements
self.tableView.frame = self.view.bounds;
[self.view addSubview:self.tableView];
}
- (void)viewWillDisappear:(BOOL)animated
{
// optionally
[self cancelWhateverYouWereWaitingFor];
[self.hud hide:animated];
}
The method -(CGRect)boundsFittingAvailableScreenSpace is part of my UIViewController+FittingBounds category. You can find its implementation here: https://gist.github.com/Tafkadasoh/5206130.
In .h
#import "AppDelegate.h"
#interface ViewController : UITableViewController
{
MBProgressHUD *progressHUD;
ASAppDelegate *appDelegate;
}
In .m
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
appDelegate = (ASAppDelegate *) [UIApplication sharedApplication].delegate;
progressHUD = [MBProgressHUD showHUDAddedTo:appDelegate.window animated:YES];
progressHUD.labelText = #"Syncing To Sever";
[appDelegate.window addSubview:progressHUD];
This should work.
[MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
And to remove you can try
[MBProgressHUD hideHUDForView:self.navigationController.view animated:YES];

How to implement not full screen file preview on ios

I know QLPreviewController could do this. But it's full screen, my requirement is preview files in a subview.
I tried use a offline window to present the QLPreviewController, and then make a screenshot of the offline window.
The problem is i have to show the window, otherwise the screen shot doesn't catch any thing.
Then my question could be, how to make screen shot for offline window in ios ?
Or you may have better ideas of implement file preview in another way.
Any tips will be appreciated.
QLPreviewController can be in a subview.
I self use it in a spliview and a subclassed QLPreviewController.
- (void)tableView:(UITableView *)tView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DocumentViewController *documentViewController = [DocumentViewController new];
[self.navigationController pushViewController:documentViewController animated:YES];
[documentViewController release];
}
where DocumentViewController is a subclass of QLPreviewController:
#interface DocumentViewController : QLPreviewController <QLPreviewControllerDataSource>
#implementation DocumentViewController
...
- (id)init
{
self = [super init];
if (self)
{
self.dataSource = self;
self.delegate = self;
}
return self;
}
...
and implement the methods witch you want (numberOfPreviewItemsInPreviewController is required for the datasource)
