I want to open file with [UIDocumentInteractionController presentPreviewAnimated];
I've created view controller
#interface FileViewController : UIViewController <UIDocumentInteractionControllerDelegate>
#end
#import "FileViewController.h"
#interface FileViewController ()
#end
#implementation FileViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (UIViewController *) documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller {
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
And trying to preview the file
UIDocumentInteractionController *controller = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
vController = [[FileViewController alloc] init];
controller.delegate = vController;
[controller presentPreviewAnimated:YES];
And get error:
Warning: Attempt to present <QLPreviewController: 0x1e56e0a0> on <FileViewController: 0x1ec3e000> whose view is not in the window hierarchy!
I may set root view controller
[[[[UIApplication sharedApplication] delegate] window] setRootViewController:vController];
But I dont want to use new view. I need to use the PhoneGap's main view. How can I do this?
The problem is solved
CDVViewController* mainController = (CDVViewController*)[ super viewController ];
[mainController addChildViewController:vController];

I am trying to add a page with a UIScrollView and UIPageControl to my app. I am making the call to the new class from a UITableView as below.
MultiPageViewController *mpvc = [[MultiPageViewController alloc]initWithNibName:#"MultiPageViewController" bundle:[NSBundle mainBundle]];
[[self navigationController]pushViewController:mpvc animated:YES];
The viewDidLoad function is never called, thus my UIScrollview and UIPageControl are never initialized. When I go along further and call viewWillAppear these objects are both still nil. Further the view never appears only a white screen. Below is the code from initWithNibName and viewDidLoad.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
NSLog(#"initWithNibName returned self != null");
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(#"View did load called");
}
Thanks for your help in advance.
I'm using the UINavigationController in my app and for some reason it won't allow me to switch pages to the third xib called CompanyView. It switches fine from first to second but not second third. I'm probably doing something wrong but if someone could look over my code that would be great. I've got the button set correctly I believe.
Here is my .h file for the xib that won't change view:
#import <UIKit/UIKit.h>
#import "CompanyView.h"
#interface MenuView : UIViewController
-(IBAction)btnClicked:(id)sender;
#end
Here is my code for the .m file:
#import "MenuView.h"
#implementation MenuView
-(IBAction)btnClicked:(id)sender {
CompanyView * companyView = [[CompanyView alloc] init];
companyView.title = #"Company";
[self.navigationController pushViewController:companyView animated:YES];
[companyView release];
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#end
Try initializing your Company View this way.
CompanyView *companyView = [[CompanyView alloc] initWithNibName:#"CompanyView" bundle:nil];
this is how i set it up:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
CategoryPresetViewController *controller = [[CategoryPresetViewController alloc] initWithPVCDelegate:avc];
controller.title = [[factoryCategoryNameArray objectAtIndex:indexPath.row] retain];
if (controller != nil){
[self.navigationController pushViewController:controller animated:YES];
[controller release];
}
maybe it can help you
Hello I'm all new to the iPhone development thingy, so I would appreciate some help here.
I would like my UIBarButton to close the app and then open up a link in safari.
in the .h file
#import <UIKit/UIKit.h>
#interface MoviesViewController : UIViewController {
IBOutlet UIBarButtonItem *rightButton_;
}
- (void) goSafari;
#end
in the .m file
#import "MoviesViewController.h"
#implementation MoviesViewController
/*
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
// Custom initialization
}
return self;
}
*/
/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
rightButton_ = [[[UIBarButtonItem alloc] initWithTitle:#"Title" style:UIBarButtonItemStyleBordered target:self action:#selector(goSafari)]autorelease];
}
- (void) goSafari {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"http://www.google.com"]];
}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return ((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
#end
Your "gosafari" method implementation is incorrectly titled - should be "goSafari" to match the specified selector and method prototype.
I am unable to load the next view on button press. I have created a button and attached the checkButtonPress action to the button in the IB. But when I press the button on the simulator the next view (ViewOne.xib) do not load. When I tried to debug the code; it is printing the NSLog(#"View One");written in the if statement below which means the code is reaching to that point but the next view is not loading. I have already created the ViewOne .h, .m .xib files. Following is the code written in check1ViewController.m implementation file:
#import "check1ViewController.h"
#import "ViewOne.h"
#implementation check1ViewController
-(IBAction) checkButtonPress: (id) sender{
int button = [sender tag];
if(button==1)
{
NSLog(#"View One");
ViewOne *tempObj = [[ViewOne alloc]initWithNibName:#"ViewOne" bundle:nil];
[self.navigationController pushViewController:tempObj animated:YES];
[tempObj release];
}
else if(button==2)
{
NSLog(#"View Two");
}
}
/*
// The designated initializer. Override to perform setup that is required before the view is loaded.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
// Custom initialization
}
return self;
}
*/
/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/
/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
}
*/
- (void)dealloc {
[super dealloc];
}
#end
The code is running fine with no errors or warnings.
Any suggestions if I am missing any part in the IB or in the code to be written or do need to override any method in any of the file ... or did I misplace IBAction before any other method
Sorry but I am new to iPhone dev so not sure what I did wrong ?
Thanks in advance
You application is not having navigation controller so add next view on window for this make object of AppDelegate class and then access window to addView.
YourAppDelegate *obj=(YourAppDelegate *)[[UIApplication sharedApplication] delegate];
[obj.window addSubView:viewController.view];
In previous applications I have customised my tabBarItems by overriding init (see below)
- (id)init {
self = [super init];
if(self) {
UITabBarItem *tabBarItem = [self tabBarItem];
[tabBarItem setTitle:#"ONE"];
}
return self;
}
After looking at the Xcode templates I am now thinking that I would be better to add this customisation to initWithNibName:bundle: instead.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
UITabBarItem *tabBarItem = [self tabBarItem];
[tabBarItem setTitle:#"ONE"];
}
return self;
}
does this make sense, it seems like it does to me, but I just wanted to check?

It depends on whether you load your controller from a Nib (xib) file or not (and so you do all the work programmatically in the init) I guess
