I would appreciate it if someone could show me (step by step), how to add an external project to an exiting app. I've been trying on my own but so far I haven't succeeded.
So how do I add Fgallery to my storyboard app?
https://github.com/gdavis/FGallery-iPhone
I'm doing this to learn so please don't get to technical with the talk, just show me and I will try to understand each step on my own. that's how I learn :)
Many thanks for your time!
first you add fgalleryappdelegate.h/m, fgalleryphoto.h/m, fgalleryphotoview.h/m, fgalleryviewcontroller.h/m and rootviewcontroller.h/m. you then edit the rootview controllers according to what you want and then you add a navigation controller to your storyboard and connect it to rootviewcontroller.
then you edit this part in rootview.m in order to get to your own pictures
pragma mark - View lifecycle
- (void)loadView {
[super loadView];
self.title = #"FGallery";
self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
localCaptions = [[NSArray alloc] initWithObjects:#"Lava", #"Hawaii", #"Audi", #"Happy New Year!",#"Frosty Web",nil];
localImages = [[NSArray alloc] initWithObjects: #"lava.jpeg", #"hawaii.jpeg", #"audi.jpg",nil];
networkCaptions = [[NSArray alloc] initWithObjects:#"Happy New Year!",#"Frosty Web",nil];
networkImages = [[NSArray alloc] initWithObjects:#"http://farm6.static.flickr.com/5042/5323996646_9c11e1b2f6_b.jpg", #"http://farm6.static.flickr.com/5007/5311573633_3cae940638.jpg",nil];

I'm pretty new to iOS programming so sorry for any "doh" questions ;)
I wanted to use the wonderful MWPhotoBrowser in my App. I'm using a TabBar Application but I can't figure out how to present the photo browser in my view. Any hints/ideas/code snippets?
Any help is very much appreciated. Thanks
This is what I have in my ViewDidLoad in the ViewController of the View of the Tab:
// Browser
NSMutableArray *photos = [[NSMutableArray alloc] init];
self.photos = [NSMutableArray array];
[photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:#"URL to 1.jpg"]]];
[photos addObject:[MWPhoto photoWithURL:[NSURL URLWithString:#"URL to 2.jpg"]]];
self.photos = photos;
// Create & present browser
MWPhotoBrowser *browser = [[MWPhotoBrowser alloc] initWithDelegate:self];
browser.displayActionButton = YES; // Show action button to save, copy or email photos
[browser setInitialPageIndex:1]; // Example: allows second image to be presented first
// Present
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:browser];
nc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:nc animated:YES];
I copied this from the Demo but now I have a view thats in front of my tab bar view, but all I want is that photo view inside my tab bar. What am I missing/obviously doing wrong?
Check GitHub link they have sample code demo. Use that sample code to modify your application. https://www.github.com/mwaterfall/MWPhotoBrowser
I need a simple UISplitViewController to be created programmatically?
Wherever i see it is only using XIB.. so kindly provide a link or example for UISplitViewController programmatically...
UISplitViewController *c = [[[UISplitViewController alloc] init] autorelease];
c.viewControllers = [NSArray arrayWithObjects:myVC1, myVC2, nil];
If you need anything more than that, you'll have to ask a better question...
I'm currently displaying a PDF file using the Quick Look framework on an iPad via the Modal View Controller. Works great. My problem is that since I'm displaying a PDF file the Quick Look preview is automatically adding a "Print" button. What I would like to do is replace the "Print" button with a custom "Email" button. Is this something that can be done? At first pass I thought this was going to be a somewhat trivial thing to do but at this point I'm really struggling with it. Any help would be greatly appreciated.
Thanks,
Brett
Since QLPreviewController is a subclass of UIViewController, you can take advantage of -[UIViewController setToolbarItems:] to customize the toolbar.
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemReply target:self action:#selector(emailPDF)];
NSArray *items = [NSArray arrayWithObject:item];
[previewController setToolbarItems:items animated:NO];
[[self navigationController] presentModalViewController:previewController animated:YES];
Now when the user taps the "reply" icon in the toolbar, your implementation of -emailPDF will get called.
you can create a subclass of QLPreviewController like MyQLPreviewController
Then in viewWillAppear:(BOOL)animated (IMPORTANT!!)
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
UIBarButtonItem *rightRatain = self.navigationItem.rightBarButtonItem;
UIBarButtonItem *email = ...;
self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:right, email, nil];
[email release];
}
In my AppDelegate, I create a UITabBarController and UINavigationController dynamically. I then add 3 views to it.
// Prepare the tab bar controller
tabBarController = [[UITabBarController alloc] init];
// Switch controller
UserSettingsController *settingsController = [[UserSettingsController alloc] init];
// Switches controller
SwitchesController *switchesController = [[SwitchesController alloc] init];
// Help controller
HelpController *helpController = [[HelpController alloc] init];
NSArray *controllers = [NSArray arrayWithObjects: switchesController, settingsController, helpController, nil];
tabBarController.viewControllers = controllers;
if (self.navigationController == nil) {
self.navigationController = [[UINavigationController alloc] initWithRootViewController:tabBarController];
}
[window addSubview:navigationController.view];
When I initially did this, I noticed that I now have a header/title bar at the top of my page. It's blank and really just takes up space. I'd like to utilize it though and add a "refresh" button to one of my views.
In the view I'm interested in, I attempted the following:
-(void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *refresh = [[UIBarButtonItem alloc] initWithTitle:#"Refresh" style:UIBarButtonItemStylePlain target:self action:#selector(refreshSwitches:)];
self.navigationItem.rightBarButtonItem = refresh;
[refresh release];
}
-(void)refresh{
...
}
No button showed up, so I'm either way off or I'm missing something.
Any suggestions?
Thanks
I believe the problem is that your view controllers that you've added to the tabbar controller are not encapsulated by navigation controllers. Although your UITabBarController has a navigation controller, this does not implicitly give all of its tabs navigation controllers (and without a nav controller, a view controller's navigationItem won't do anything.) To remedy this problem I'd suggest encapsulating your view controllers with navigation controller upon initialization:
ex:
UserSettingsController *settingsController = [[UserSettingsController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:settingsController];
[settingsController release];
// etc...
NSArray *controllers = [NSArray arrayWithObjects:navController, ..., ..., nil];
tabBarController.viewControllers = controllers;
// Release your nav controllers, other cleanup
EDIT
Okay, I think I have a better idea of your setup now. I was able to get the following to work:
self.tabBarController.navigationItem.rightBarButtonItem = myButton;
An important caveat of this is that the button will persist on all of your tabbarcontroller's views unless you explicitly remove it. This may prove annoying/inelegant to maintain, but I am not sure of another solution if the view you want to have the button is not directly associated to a nav controller itself.
I'm triying to combine a TabBar + Navigation app.
I have 5 tab bars, 4 are listing of stuff and drill down to details views.
I try to follow this tutorial:
http://www.iphonedevforums.com/forum/iphone-sdk-development/124-view-controller-problem.html
But always get a blank view.
This is what I do, with a clean project:
I start with a TabBar template app.
I put 5 tab bar buttons.
I create a controller like:
#interface FirstViewController : UINavigationController {
}
I put the main window.xib on tree mode & change the selected first view to FirstViewController
I select the TabBar Controller in Interface builder, go to TabBar Attributes & change the class to navigation controler.
Select the fist view & put the nib name "SecondView"
In response, I get a blank screen.
I must add that I wanna navigate from the details views, no from the main windows.
i.e in the main window tab bar 1 is the list of people. I select a person then wanna navigate to the detail window.
First, you never want to subclass UINavigationController or UITabBarController.
Second, I did not quite get what you did, but a correct sequence to create a navigation controller inside a tab bar controller is something like this:
// in MyAppDelegate.h
UINavigationController *nc1, *nc2;
FirstTabRootViewController *vc1;
SecondTabRootViewController *vc2;
UITabBarController *tbc;
// in MyAppDelegate.m
nc1 = [[UINavigationController alloc] init];
vc1 = [[FirstTabRootViewController alloc] initWithNibName:nil bundle:nil];
vc1.tabBarItem.title = #"Tab 1";
vc1.tabBarItem.image = [UIImage imageNamed:#"tab1.png"];
vc1.navigationItem.title = "Tab 1 Data";
nc1.viewControllers = [NSArray arrayWithObjects:vc1, nil];
nc2 = [[UINavigationController alloc] init];
vc2 = [[SecondTabRootViewController alloc] initWithNibName:nil bundle:nil];
vc2.tabBarItem.title = #"Tab 2";
vc2.tabBarItem.image = [UIImage imageNamed:#"tab2.png"];
vc2.navigationItem.title = "Tab 2 Data";
nc2.viewControllers = [NSArray arrayWithObjects:vc2, nil];
tbc = [[UITabBarController alloc] init];
tbc.viewControllers = [NSArray arrayWithObjects:nc1, nc2, nil];
Note that it's your view controller that controls the text/icon in the tab bar and in the navigation bar. Create a UINavigationController instance for each of your tabs; UINavigationController contains a stack of view controllers (see viewControllers property) which should contain at least one item — your root controller for that tab. Also create an UITabBarController to manage the tabs.
Of course, you can (and probably should) use interface builder instead of code to instantiate the mentioned classes and set the properties. But it's important that you understand what happens behind the scenes; interface builder is nothing more than a convenient way to instantiate and set up objects.
Hope this is helpful; please refine your question if it's not.
Still getting the blank screen On Starting the application after implementing the above code. Where i 'm writing it wrong.
nc1 = [[UINavigationController alloc] init];
nc2 = [[UINavigationController alloc] init];
vc1 = [[FirstRootViewController alloc]initWithNibName:#"FirstRootViewController" bundle:nil];
vc1.tabBarItem.title = #"Item 1";
vc1.tabBarItem.image= [UIImage imageNamed:#"home.png"];
vc1.navigationItem.title = #"Tab1 Data";
nc1.viewControllers = [NSArray arrayWithObjects:vc1,nil];
vc2 = [[SecondRootViewController alloc]initWithNibName:#"SecondRootViewController" bundle:nil];
vc2.tabBarItem.title = #"Item 2";
vc2.tabBarItem.image= [UIImage imageNamed:#"home.png"];
vc2.navigationItem.title = #"Tab2 Data";
nc2.viewControllers = [NSArray arrayWithObjects:vc2,nil];
tbc = [[UITabBarController alloc]init];
tbc.viewControllers = [NSArray arrayWithObjects:nc1,nc2,nil];
[window addSubview:tbc.view];
[window makeKeyAndVisible];
Here is an tutorial that I was able to get working.
I also read the official SDK documentation on the topic: Combining Tab Bar and Navigation Controllers. Since I'm still learning, the tutorial helped me more than the docs.
NOTE: in the tutorial, i don't think you need to subclass UINavigationController, and I'm experimenting with this idea now.
I tried to create an iphone application with UITabBarController and some UINavigationController inside it and faced the same problems as "mamcx". With your example-code i get it to run :) Thanks a lot.
Here is how it works for me.
// YOURS
fourthNavigation = [[UINavigationController alloc ] init ];
fourthViewController = [[[FourthTabRootController alloc] initWithNibName:#"FourthView" bundle:nil] autorelease];
fourthNavigation.tabBarItem.title = #"YOURS";
fourthNavigation.viewControllers = [NSArray arrayWithObjects:fourthViewController, nil];
// Add self-defined UIViewControllers to the tab bar
tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigation,secondNavigation, thirdNavigation, fourthNavigation, nil];
// Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
The other UINavigationControllers "firstNavigation, ... " are created the same way.
I load the view elements from nib-files that are connected to my subclassed UIViewController classes. You dont need to add a NavigationBar in the IB to your view, cause the UINavigationController has allready one. So you only need to set the title in "initWithNibName"
// 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
self.title = #"YOURS";
}
return self;
}
I hope that helps.
Check out "Adding a Navigation Controller to a Tab Bar Interface" under View Controller Catalog for iOS which take you step by step into how exactly this can be achieved
