I am having a little hard time here, forgive me if you think my problem is so easy for you.
I am trying to create app using UISplitView. The 1st View on the left is a TableView and the other one on the right is just a normal view.
This is my Code for in AppDelegate.m for UISplitView.
#import "AppDelegate.h"
#import "MasterViewController.h"
#import "DetailViewController.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
MasterViewController *masterVC = [[MasterViewController alloc]init];
DetailViewController *detailVC = [[DetailViewController alloc]init];
UISplitViewController *splitVC = [[UISplitViewController alloc]init];
[splitVC setViewControllers:[NSArray arrayWithObjects:masterVC,detailVC,nil]];
[self.window setRootViewController:splitVC];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
Now, I want to add a Navigation Bar on the TableView, I just don't know how to add if I am using SplitView,but I can when I am using a single TableView.
This is my Code in AppDelegate.m using a single View Application that uses TableView. (This is working)
#import "AppDelegate.h"
#import "ViewController.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
//create UINavigationController
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
Hope you can understand what I'm trying to say. I can't post images since i don't have enough reputation. AGAIN.. The question is "How can I add Navigation Controller in my TableView if I used UISplitView?"
Do you think it will be easy for me if I use storyboards instead of using two XIB files?Hope you can help me.
Thanks in advanced!
try this code
in AppDelegate.h file
UINavigationController *detailNavigationController;
UINavigationController *masterNavigationController;
UISplitViewController *HomeSpilitView;
HomeSpilitViewController *HomeMster;
HomeDetailsViewController *HomeDetailsViewControllers;
in AppDelegate.m file
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
NSMutableArray *array = [NSMutableArray array];
HomeSpilitView = [[[UISplitViewController alloc] init]autorelease];
HomeMster = [[HomeSpilitViewController alloc] initWithNibName:#"HomeSpilitViewController" bundle:nil];
masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeMster] autorelease];
HomeMster.title=#"Title home";
masterNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
[array addObject:masterNavigationController];
HomeDetailsViewController *HomeDetailsViewControllers = [[HomeDetailsViewController alloc] initWithNibName:#"HomeDetailsViewController" bundle:nil];
detailNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeDetailsViewControllers] autorelease];
detailNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
HomeDetailsViewControllers.title=#"details title";
HomeMster.objHomeDetailsViewcontroller=HomeDetailsViewControllers;
HomeSpilitView.delegate = HomeDetailsViewControllers;
[array addObject:detailNavigationController];
[HomeSpilitView setViewControllers:array];
[self.window setRootViewController:HomeSpilitView];
[self.window makeKeyAndVisible];
return YES;
}

this is demo ,I set RootViewController in didFinishLaunchingWithOptions,but viewController's viewWillAppear is not called! I guess it's because the NavigationController added the ViewController that the response chain of the message failed?
I know it should be set to
self.window.rootViewController = navigationController
But I want to know what I set to
self.window.rootViewController = mainViewController
Why not call mainViewController's viewWillAppear? Thank you.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
ViewController *mainViewController = [[ViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mainViewController];
self.window.rootViewController = mainViewController;
[self.window makeKeyAndVisible];
return YES;
}
viewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
}
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
NSLog(#"viewWillAppear");
}
#end
Hm... interesting.
Keeping the following:
[[UINavigationController alloc] initWithRootViewController:mainViewController];
even though it's not used, seems to be stealing the ViewController's viewDidAppear.
If you comment that line then it works as you want.
i.e:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
ViewController *mainViewController = [[ViewController alloc] init];
//Comment the navigationController instantiation
//UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:mainViewController];
self.window.rootViewController = mainViewController;
[self.window makeKeyAndVisible];
return YES;
}
Maybe the navigationController was set to own the ViewController but since it's not presented on the screen, neither the viewDidLoad nor viewDidAppear occurs until later, but... when you reassign the ViewController to the window, the internal view loading logic feels viewDidAppear is no longer needed to be called.
Maybe a bug or intentional, I don't know.
Note: I don't really have a reason for this behavior. I am just shedding light on what caused it.
I copied the example from View Controller Catalog for iOS made some changes to the colour and expected to see them reflected on the simulator. Nothing happens ???
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UIViewController *myViewController = [[MyViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myViewController];
[navigationController setNavigationBarHidden:NO animated:YES];
navigationController.title = #"Hello";
navigationController.navigationBar.barStyle = UIBarStyleBlack ;
navigationController.navigationBar.translucent = NO;
navigationController.navigationBar.tintColor = [UIColor blackColor];
navigationController.navigationBar.barTintColor = [UIColor greenColor];
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.rootViewController = navigationController;
[window makeKeyAndVisible];
return YES; }
What do I do wrong?
Several things: First: be sure than in the General information of your target app, in Main Interface field is blank. (If you don´t find it, delete all *.storyboard files that you have).
Second: In your AppDelegate.h should be this property:
#property (strong, nonatomic) UIWindow *window;
And last: Change this in your code:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
In order to know changes is better step by step. (.title is in ViewController).
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
MainViewController *rootViewController = [[MainViewController alloc] init];
_naviControl = [[UINavigationController alloc]initWithRootViewController:rootViewController];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
[self.window addSubview:_naviControl.view];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
In my AppDelegate ..!
Connect to MainViewController.m
The AppDelegate is not a UIViewController so connecting a UITableView to it conflicts with the MVC principles as described here: https://developer.apple.com/library/ios/documentation/general/conceptual/devpedia-cocoacore/MVC.html
what you want to do is make your MainViewController's view have a tableView as a subview
something like this:
(in MainViewController.m)
- (void)viewDidLoad {
[super viewDidLoad];
self.feedTableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];
self.feedTableView.dataSource = self;
self.feedTableView.delegate = self;
[self.view addSubview:self.feedTableView];
}
Bellow i have some code that is place in the app delegate.m and is used to create a c between two ViewControllers. The creation of the tab bar works fine but when i select the setting tab there is no view it is just black.
Here is the code:
import "ViewController.h"
#import "Settings.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]init];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
return YES;
}
You write the code for setting screen like this
Settings *vc2 = [[Settings alloc]init];
where is the nib file for setting screen ,
Once try like this
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]initWithNibName:#"Settings" bundle:nil];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
[self.window makeKeyAndVisible];
try with:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]init];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
[self.window makeKeyAndVisible];
return YES;
}
I really don't know how to explain this without pasting all my code, but ill give it a shot. "Assuming" my .hs and .ms are accurate, i have a feeling my .xib is not set correctly, but i cant really paste the code from that. Instead i've zipped the files and uploaded the source code. (if you are brave enough, it's here: http://bit.ly/ZtDkGi ) Im getting a successful build, but my emulator's screen is just black after the app launches.
Essentially, i had to manually add an appDelegate object. i set the class to the appropriate class - but its still not pulling. If someone would be kind enough to help, that would be great.
here's my Test_TableViewAppDelegate.h
#import <UIKit/UIKit.h>
#interface Test_TableViewAppDelegate : NSObject <UIApplicationDelegate>
{
}
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet UINavigationController *navController;
#end
here's my new Test_TableViewAppDelegate.m
#import "Test_TableViewAppDelegate.h"
#implementation Test_TableViewAppDelegate
#synthesize window=_window;
#synthesize navController=_navController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
//self.window.backgroundColor = [UIColor whiteColor];
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.backgroundColor = [UIColor greenColor];
self.window = window;
UIViewController *fvc = [[UIViewController alloc] init];
UIViewController *rootController = [[UIViewController alloc] initWithNibName:#"RootViewController" bundle:nil];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:rootController];
//UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:fvc];
self.navController = nc;
//[self.window addSubview: nc.view];
//[self.window makeKeyAndVisible];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
return YES;
}
RootViewController.h
#import <UIKit/UIKit.h>
#interface RootViewController : UITableViewController {
NSMutableArray *petsArray;
}
#end
RootViewController.m
#import "RootViewController.h"
#interface RootViewController ()
#end
#implementation RootViewController
and last but not least, main.m ( i think this might be an issue too)
#import "Test_TableViewAppDelegate.h"
int main(int argc, char *argv[])
{
#autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([Test_TableViewAppDelegate class]));
}
}
thanks in advance. i'd appreciate it :D
in your delegate Test_TableViewAppDelegate
why you adding views two times to the window?
// you could remove these two lines
[self.window addSubview: nc.view];
[self.window makeKeyAndVisible];
//keep these two lines
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
And this view you are adding to the navigationController it is not initalized with any nib name
UIViewController *fvc = [[UIViewController alloc] init];
initialization should be like this instead in your delegate
RootViewController *rootController = [[RootViewController alloc] initWithNibName:#"RootViewController" bundle:nil];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:rootController];
I believe the reason that you're getting a black screen is that you are not properly allocating and initializing your navigation controller!
Instead, you should try this code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
// create the base window
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.backgroundColor = [UIColor greenColor];
self.window = window;
[window release];
// this is the home page from the user's perspective
FirstViewController *fvc = [[FirstViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc]initWithRootViewController:fvc];
self.navigationController = nc;
[fvc release];
[nc release];
// show them
[self.window addSubview: nc.view];
[self.window makeKeyAndVisible];
return YES;
}
Hope this works!
