I am creating an iphone application, where i have number of grid views in a main view controller class. So, i want when i select a grid cell from main view, should load a Reveal controller. The layout looks like
I have the following code in my Main View Controller.
-(void) gridView:(UzysGridView *)gridView didSelectCell:(UzysGridViewCell *)cell
atIndex:(NSUInteger)index
{
if (index == 0){
FrontViewController *frontViewController = [[FrontViewController alloc]
init];
RightViewController *rightViewController = [[RightViewController alloc] init];
UINavigationController *frontNavigationController = [[UINavigationController alloc]
initWithRootViewController:frontViewController];
SWRevealViewController *mainRevealController = [[SWRevealViewController alloc]
initWithRearViewController:nil
frontViewController:frontNavigationController];
mainRevealController.delegate = self;
self.revealController.rightViewController = rightViewController;
self.revealController = mainRevealController;
[self.navigationController pushViewController:self.revealController animated:YES];
}
here in main view controller .h file,
#property (strong, nonatomic) SWRevealViewController *revealController;
Also i have declare SWRevealViewControllerDelegate. Problem is that this self.revealController doesn't load/show. I have tried with App Delegate also, but nothing works.
thanks.
I solved it: Use the below code..
-(void) gridView:(UzysGridView *)gridView didSelectCell:(UzysGridViewCell *)cell
atIndex:(NSUInteger)index {
if (index == 0){
FrontViewController *frontViewController = [[FrontViewController alloc]
init];
myNavigationController = [[UINavigationController alloc]
initWithRootViewController:frontViewController];
SWRevealViewController *revealController = [[SWRevealViewController alloc]
initWithRearViewController:nil frontViewController:myNavigationController];
revealController.delegate = self;
RightViewController *rightViewController =
[[RightViewController alloc] init];
rightViewController.view.backgroundColor = [UIColor greenColor];
revealController.rightViewController = rightViewController;
self.viewController1=revealController;
[self presentViewController:self.viewController1 animated:YES completion:nil];
}
}
And in Class.h file
#property(nonatomic, strong) UINavigationController *myNavigationController;
#property(nonatomic, strong) SWRevealViewController *viewController1;

I have added Two Tabs in my app, to load two view controller using these tabs
Tab1 : Home
Tab2 : Favourite
so I have written below code to achieve this
In app Delegate
AppDelegate.h
#class ViewController,FavViewController;
#interface AppDelegate : UIResponder <UIApplicationDelegate>
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) ViewController *viewController;
#property (strong, nonatomic) FavViewController *favViewController;
#property (strong, nonatomic) UITabBarController *tabBarController;
#end
AppDelegate.m
#implementation AppDelegate
#synthesize window = _window;
#synthesize viewController;
#synthesize favViewController;
#synthesize tabBarController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
baseTabBarController = [[UITabBarController alloc]init];
baseTabBarController.delegate=self;
viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UINavigationController *homeView = [[UINavigationController alloc]initWithRootViewController:viewController];
favViewController = [[FavViewController alloc] initWithNibName:#"FavViewController" bundle:nil];
favViewController.title = #"My Favourite";
UINavigationController *favouriteView = [[UINavigationController alloc] initWithRootViewController:favViewController];
NSArray *controllers = [NSArray arrayWithObjects:homeView,favouriteView, nil];
baseTabBarController.viewControllers = controllers;
[self.window addSubview:baseTabBarController.view];
[self.window makeKeyAndVisible];
return YES;
}
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)selectedViewController
{
if (tabBarController.selectedIndex == 0) {
}else if (tabBarController.selectedIndex == 1) {
[(FavViewController *)[(UINavigationController*)selectedViewController topViewController] getData];
}else if (tabBarController.selectedIndex == 2) {
NSLog(#"2");
}
}
and here is the Result Screen I am getting
So Where I am having trouble in this..
If I switch to the next screen my First tab doesn't load First Screen (Home screen) instead just stay on current screen.
Let me try with example
There are four screens in my app let say A, B, C, D
I have added Tabs for A and C screens,those are available in whole app
(All screen).
Now if I'll start app and go A ->B->C -> D and press on Home Tab (A)
it doesn't load Screen A, instead just stay on Current screen
but good thing is if i do same process with another tab C (My
Favourite) it loads correct screen.
Edit: I have implemented didSelectViewController method as #sanjit suggested me but in that I not able distinguish, which tab is tapped this time?
I would be really appreciate!! if someone can point me on right direction
Use Tabbar delegate and using parameter instance of uiviewcontroller call poptorootviewcontroller method. Hope it may work for you. Try the following code
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
UINavigationController *navController = (UINavigationController*)tabBarController.selectedViewController;
[navController popToRootViewControllerAnimated:YES];
}
replace the code
[viewController setTabBarItem:tab1];
[favViewController setTabBarItem:tab2];
with
[[tabbarController tabBar] setItems:[NSArray arrayWithObjects:tab1,tab2, nil]];
that should resolve.
Viewcontroller.h
#property(nonatomic, retain) UITabBarItem *item1;
#property(nonatomic, retain) UITabBarItem *item2;
#property(nonatomic, retain) UITabBarItem *item3;
#property(nonatomic, retain) UITabBarItem *item4;
#property(nonatomic, retain) IBOutlet UITabBar *tabBar;
Viewcontroller.m
#synthesize item1,item2,item3,item4,tabBar;
- (void)viewDidLoad
{
item1 = [[UITabBarItem alloc] initWithTitle:#"Home" image:[UIImage imageNamed:#"home.png"] tag:0];
item2 = [[UITabBarItem alloc] initWithTitle:#"My Lists" image:[UIImage imageNamed:#"mylist"] tag:1];
item3 = [[UITabBarItem alloc] initWithTitle:#"Search" image:[UIImage imageNamed:#"search.png"] tag:2];
item4 = [[UITabBarItem alloc] initWithTitle:#"Settings" image:[UIImage imageNamed:#"setting.png"] tag:3];
NSArray *items = [NSArray arrayWithObjects:item1,item2,item3,item4, nil];
[tabBar setItems:items animated:NO];
[tabBar setSelectedItem:[tabBar.items objectAtIndex:2]];
tabBar.delegate=self;
[self.view addSubview:tabBar
];
}
/****Function Call******/
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
if(item.tag == 0)
{
Newsfeeds *obj = [[Newsfeeds alloc]initWithNibName:#"Newsfeeds" bundle:Nil];
[self.navigationController pushViewController:obj animated:NO];
}
else if(item.tag == 1)
{
MyLists *obj = [[MyLists alloc]initWithNibName:#"MyLists" bundle:Nil];
[self.navigationController pushViewController:obj animated:NO];
}
else if(item.tag == 3)
{
Settings *obj = [[Settings alloc]initWithNibName:#"Settings" bundle:Nil];
[self.navigationController pushViewController:obj animated:NO];
}
}
I have two table view in one view controller.
They works great! But they are not pushing to any vc.
Under -(void) viewDidLoad method in my main view controller:
horizontalViewController = [[HorizontalViewController alloc] init];
verticalViewController = [[VerticalViewController alloc] init];
[horizontalTableView setDataSource:horizontalViewController];
[verticalTableView setDataSource:verticalViewController];
[horizontalTableView setDelegate:horizontalViewController];
[verticalTableView setDelegate:verticalViewController];
horizontalViewController.view = horizontalViewController.tableView;
verticalViewController.view = verticalViewController.tableView;
What can I do?
Thanks.
refer a following code. If you want use a pushViewController method.
You must be have a NavigationViewController.
so, your structure is a little complex. one ViewController has number of Two TableViewController. one ViewController is not have NavigationController. NavigaitonViewController necessarily belong to the app when it runs because it should be configured.
TwoTableViewsAppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UINavigationController *naviController = [[[UINavigationController alloc] initWithRootViewController:viewController] autorelease];
[window setRootViewController:naviController];
[window makeKeyAndVisible];
return YES;
}
TwoTableViewsViewController.m
- (void)viewDidLoad {
if (firstController == nil) {
firstController = [[FirstTVContoller alloc] init];
}
if (secondController == nil) {
secondController = [[SecondTVController alloc] init];
}
[firstTable setDataSource:firstController];
[secondTable setDataSource:secondController];
[firstTable setDelegate:firstController];
[secondTable setDelegate:secondController];
firstController.view = firstController.tableView;
secondController.view = secondController.tableView;
firstController.rootViewController = self;
secondController.rootViewController = self;
[super viewDidLoad];
}
FirstTVContoller.h , SecondTVController.h
#import <Foundation/Foundation.h>
#interface FirstTVContoller : UITableViewController <UITableViewDataSource, UITableViewDelegate>{
NSMutableArray *items;
}
#property (nonatomic, retain) UIViewController *rootViewController;
#end
FirstTVContoller.m , SecondTVController.m
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
VerticalDetailViewController *verticalDetailViewController = [[VerticalDetailViewController alloc] initWithNibName:#"VerticalDetailViewController" bundle:nil];
[[self.rootViewController navigationController] pushViewController:verticalDetailViewController animated:YES];
}
I am making an application which will have 3 pages
Login Page - first page after the app loads
My First Page- when user successfully logs in then he comes into this page.This page
contains a UITabBar with two UITabBarItems. The first one is connected to
My firstPage
and the other one to My Second Page.
My Second Page - this is another UIViewController.
I have made the login page but I am unable to find the solution to UITabBar adding in My First Page
Please help me out
Define
AppDelegate.h
#property (strong, nonatomic) UITabBarController *tabBarController;
in AppDelegate.m
didFinishLaunchingWithOptions
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.delegate=self;
self.tabBarController.selectedIndex=0;
self.tabBarController.delegate=self;
- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{
return YES;
}
now when you get success login write below code in that method
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
delegate.tabBarController = [[UITabBarController alloc] init];
delegate.tabBarController.selectedIndex = 0;
delegate.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
delegate.tabBarController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self.navigationController pushViewController:delegate.tabBarController animated:YES];
Try this out,
suppose this is LoginViewController.m
-(IBAction)loginButtonClicked:(id)sender
{
[self createTabBarView];
}
//Create TabBar View here
-(void)createTabBarView
{
NSMutableArray *tabItems = [NSMutableArray array];
UIViewController *firstViewController = [[FirstViewController alloc] init];;
firstViewController = #"First View";
firstViewController = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemContacts tag:0];
[tabItems addObject:firstViewController];
UIViewController *secondViewController = [[SecondViewController alloc] init];;
secondViewController = #"Second View";
secondViewController = [[UITabBarItem alloc]initWithTabBarSystemItem:UITabBarSystemItemContacts tag:1];
[tabItems addObject:secondViewController];
self.tabBarController = [[UITabBarController alloc]init];
self.tabBarController.viewControllers = tabItems;
self.tabBarController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:tabBarController animated:YES];
}
Thanks,
Nikhil.
Are you using interface builder?
From my point of view, I'd rather like to use programmatic way to implement it.
//In the appDidFinishLaunch method
BOOL loggedIn = [[NSUserDefault standDefault]boolForKey:"userlogin"];
if(loggedIn)
{
//Setup your UITabbarViewController
}
else
{
//Setup your loginView Controller
}
After login in LogInViewController
- (void)didLogin
{
YourAppDelegate *delegate = [UIApplication shareApplication].delegate;
[delegate.window addSubView:self.tabBarViewController.view];
[delegate.window removeSubView:self.view]
//Other Config
}
You should create Tabbar at place where you can identify that login is successfully done. This method should be part of your loginViewController.
Create a function like below to create a Tabbar and present it over loginController.
-(void) createTabBarController
{
UITabBarController *tabBar = [[UITabBarController alloc]init];
UIViewController *firstViewController = [[[UIViewController alloc] init]autorelease];
UINavigationController *firstNavController = [[UINavigationController alloc]initWithRootViewController:firstViewController];
firstNavController.tabBarItem.title=#"First Controller";
firstNavController.tabBarItem.image = [UIImage imageNamed:#"first.png"];
UIViewController *secondViewController = [[[UIViewController alloc] init]autorelease];
UINavigationController *secondNavController = [[UINavigationController alloc]initWithRootViewController:secondViewController];
secondNavController.tabBarItem.title=#"First Controller";
secondNavController.tabBarItem.image = [UIImage imageNamed:#"first.png"];
[tabBar setViewControllers:[NSArray arrayWithObject:firstNavController,secondNavController,nil]];
[firstNavController release];
[secondNavController release];
[self presentModalViewController: tabBar];
[tabBar release];
}
I have following coding in my Program, in AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
myList = [[List alloc] init];
mySettings = [[Settings alloc] init];
myCriteria = [[Criteria alloc] initWithStyle:UITableViewStyleGrouped];
first = [[UINavigationController alloc] initWithRootViewController:myList];
second = [[UINavigationController alloc] initWithRootViewController:mySettings];
third = [[UINavigationController alloc] initWithRootViewController:myCriteria];
myTabBar = [[UITabBarController alloc] init];
myTabBar.view.frame = CGRectMake(0,20,320,460);
UITabBarItem *first1 = [[UITabBarItem alloc] initWithTitle:#"List" image:[UIImage imageNamed:#"list.png"] tag:0];
UITabBarItem *second2 = [[UITabBarItem alloc] initWithTitle:#"My Profile" image:[UIImage imageNamed:#"settings.png"] tag:1];
UITabBarItem *third3 = [[UITabBarItem alloc] initWithTitle:#"Criteria" image:[UIImage imageNamed:#"Criteria.png"] tag:2];
UINavigationController *localNavigationController = [[UINavigationController alloc] initWithRootViewController:myTabBar];
first.tabBarItem = first1;
second.tabBarItem = second2;
third.tabBarItem = third3;
myControllerArray = [[NSArray alloc] initWithObjects:first, second, third, nil];
[myTabBar setViewControllers:myControllerArray];
[myTabBar setCustomizableViewControllers:myControllerArray];
[self.window addSubview:myTabBar.view];
// Add the view controller's view to the window and display.
// [self.window addSubview:viewController.view];
[self.window makeKeyAndVisible];
return YES;
}
Where these three are different classes, now I want to use camera and album, so when I write coding as below on a button target, it won't work
- (void) useCamera
{
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
NSLog(#"If is true");
UIImagePickerController *imagePicker =
[[UIImagePickerController alloc] init];
// [self.navigationController pushViewController:imagePicker animated:YES];
imagePicker.delegate = self;
imagePicker.sourceType =
UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:
(NSString *) kUTTypeImage,
nil];
imagePicker.allowsEditing = NO;
[self.tabBarController setCustomizableViewControllers:[[NSArray alloc]initWithObjects:imagePicker,self,nil]];
[self.tabBarController setViewControllers:[[NSArray alloc]initWithObjects:imagePicker,self,nil]];
//[self presentModalViewController:imagePicker animated:YES]; I tried
//[self.view addSubview:imagePicker.view]; I tried
//self.view=imagePicker.view; I tried
//[myScrollView addSubview:imagePicker]; I tried
//[myView addSubview:imagePicker]; I tried
[imagePicker release];
newMedia = YES;
}
}
I tried all the above ways but they are not working and showing UIImagePickerController,
now what should I do
if anyone in not clear from my question, can ask me again.....
What about [self.view addSubview:imagePicker.cameraOverlayView]
Also, have you tried adding any other view to your self.view? I wonder if the imagePicker is being added, but is not loaded because the view you are adding it to is not being displayed.
Did u try presenting the imagePicker through one of the navigation controllers?
From Reference
Present the user interface by calling the presentModalViewController:animated: method of the currently active view controller, passing your configured image picker controller as the new view controller. On iPad, you can alternatively present the user interface using a popover as described in initWithContentViewController: and “Presenting and Dismissing the Popover” in UIPopoverController Class Reference.
If using GKImagePicker:
[self.view addSubview:self.imagePicker.imagePickerController.view];
You can always do:
let cam = UIImagePickerController()
cam.delegate = self
cam.sourceType = .camera
self.show(cam, sender: nil)
worked for me
Did you try presenting the UIImagePickerController through the tabBarController (UITabBarController inherits from UIViewController)? Assuming that you created a singleton for for your AppDelegate and that the tabBarController is a property of the AppController (for your convenience I added a sample code for the singleton below), the code would look something like this:
AppController.h
#import <UIKit/UIKit.h>
#interface AppController : NSObject <UIApplicationDelegate> {
UITabBarController *tabBarController;
}
// Class methods for convenience
+ (AppController *)sharedAppController;
// *** Properties
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) UITabBarController *tabBarController;
#end
AppController.m
#import "AppController.h"
static AppController *sharedInstance;
#implementation AppController
#synthesize window=_window;
#synthesize tabBarController;
#pragma mark - Initialization
- (id)init
{
// Create the sharedInstance of the application
if (sharedInstance) {
NSLog(#"Error: You are creating a second AppController");
}
[super init];
sharedInstance = self;
return self;
}
+ (AppController *)sharedAppController
{
return sharedInstance;
}
- (void)dealloc
{
[_window release];
[tabBarController release];
[super dealloc];
}
Now in your class, on the useCamera method call the imagePicker by doing this:
- (void)useCamera
{
// YOUR CODE ...
// Place image picker
[[[AppController sharedAppController] tabBarController]
presentModalViewController:imagePicker animated:YES];
// YOUR RELEASE CODE ...
}
Good luck and happy coding!
can we use UITab bar controller in view base application thank you
Yes you can.
you can look at the "TheElements" example that apple provides.
you can find it here:
https://developer.apple.com/library/ios/#samplecode/TheElements/Introduction/Intro.html
look at the app delegate.
its very strait forward example.
for you request i tried to make a simple example:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self setupPortraitUserInterface];
return YES;
}
- (UINavigationController *)AchievementsControllerWrappingViewController:(NSInteger*)tabIndex{
switch(tabIndex){
case 0:
FirstViewController *theViewController;
theViewController = [[FirstViewController alloc] init];
break;
case 1:
SecondViewController *theViewController;
theViewController = [[SecondViewController alloc] init];
break;
}
UINavigationController *theNavigationController;
theNavigationController = [[UINavigationController alloc] initWithRootViewController:theViewController];
[theViewController release];
return theNavigationController;
}
- (void)setupPortraitUserInterface {
UINavigationController *localNavigationController;
UIWindow *localWindow;
localWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window = localWindow;
[localWindow release];
tabBarController = [[UITabBarController alloc] init];
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:2];
for(int i=0;i<2;i++){
localNavigationController = [self AchievementsControllerWrappingViewController:i];
[localViewControllersArray addObject:localNavigationController];
[localNavigationController release];
}
tabBarController.viewControllers = localViewControllersArray;
[localViewControllersArray release];
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
}
i am not next to xCode and i did it with text edit, so please check it when you use it.
shani
Yes we can..
For that you have to create UITabBarViewController and its Object then refrence it with you Application..like :
in your AppDelegate.h
#interface youAppDelegate.h : UIApplicationDelegate {
UIWindow *window;
YourViewController *viewController;
// Declare Your TabBarController Here
UITabBarController *tabBar;
}
#property (nonautomic, retain) IBOutlet UIWindow *window;
#property (nonautomic, retain) IBOutlet TabBarViewController *tabBar;
#end
in you implementation file's ApplicationDidFinish Launching add the following Code
viewController = [[YourViewController alloc] init];
[viewController addSubView:tabBar];
[self.window addSubView:viewController];
In interface builder you have to add the TabBarController to your MainWindow and relate it with the IBOutLet. Give what ever view you want to display in tabBar.
enjoy..
