I try change to background of navigationBar.
Search.h:
#import <UIKit/UIKit.h>
#interface Search : UIViewController
#end
Search.m:
#import "Search.h"
#implementation Search
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImage *image = [UIImage imageNamed:#"navigation_header.png"];
[self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
I can't change navigation background.
Thanks.
This is actually simpler to do then you think. In your app delegate...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"NavBar.png"] forBarMetrics:UIBarMetricsDefault];
return YES;
}
This will universally change your navigation bar background image.
Note: I believe UINavigationBar's "appearance" property is available in iOS 5 and up.
viewController.h
IBOutlet UINavigationBar *navBar;
viewController.m
//for color
- (void)viewDidLoad{
[super viewDidLoad];
[navBar setTintColor:[UIColor colorWithRed:0.0/255.0 green:100.0/255.0 blue:20.0/255.0 alpha:1.0]];
}
//for image
UIImage *image = [UIImage imageNamed:#"navigation_header.png"];
[self.navigationController.navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[Search alloc] initWithNibName:#"Search" bundle:nil] autorelease];
navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController];
[self.window addSubview:[navControl view]];
[self.window makeKeyAndVisible];
}
Write this method in AppDelegate.m. I think it will be helpful to you.

I am developing a simple browser project on mac, i didn't use the default viewcontroller.
Instead, I write a viewcontroller class BrowserViewController.
and write follow in appdelegate
#interface AppDelegate()
#property (nonatomic, strong) BrowserViewController *browserController;
#end
#implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// Insert code here to initialize your application
self.browserController = [[BrowserViewController alloc] init];
[self.window makeKeyWindow];
[self.window setContentView:self.browserController.view];
}
#end
But when the app start up it lead to the default viewcontroller not the BrowserViewController. I really don't know the reason.
Thanks for the help, i have solve this problem. My solution is like this:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
//set the frame of the window fit to the device's frame
//
self.window = [[NSWindow alloc] initWithContentRect:[[NSScreen mainScreen] frame] styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered defer:NO ];
//
//
self.browserController = [[BrowserViewController alloc] init];
//set contentView
//
self.window.contentViewController = self.browserController;
//this is setting global backgroundColor of the window
//
self.window.backgroundColor = [NSColor whiteColor];
//this means the window is the window that will receive user interaction.
//
[self.window makeKeyAndOrderFront:self];
//[self.window makeKeyWindow];//NOTE: This is not working.
}
You can select Is Initial Controller in the storyboard.
Sounds like you're looking for (inside your didFinishLaunchingWithOptions method):
self.browserController = [[BrowserViewController alloc] init];
[self.window setRootViewController: self.browserController];
[self.window makeKeyAndVisible];
If you want it programmatically:
Note
This is for iOS, but the logic are identical. Hope this will be useful for some reason.. :)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//set the frame of the window fit to the device's frame
//
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//what you have above is correct
//
self.browserController = [[BrowserViewController alloc] init];
//you can also directly set it like
//
BrowserViewController *mainView = [[BrowserViewController alloc] init];
//this is the most important, you need to set the window's rootViewController
//
self.window.rootViewController = mainView;
//this is setting global backgroundColor of the window
//
self.window.backgroundColor = [UIColor whiteColor];
//this means the window is the window that will receive user interaction.
//
[self.window makeKeyAndVisible];
return YES;
}
Hope this is helpful and informative.. Cheers! :)
I'm trying to create a MFSideMenu however I never used it and do not know what it missing. Can anyone write a short tutorial on how to finalize it?
-(void)viewDidLoad{
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:centerViewController
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
}
In AppDelegate.h
#import "MFSideMenuContainerViewController.h"
In AppDelegate.m
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UINavigationController *navigationController = [self.storyboard instantiateViewControllerWithIdentifier:#"navigationController"]; //I have instantiated using storyboard id.
UIViewController *leftSideMenuViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"sideMenuViewController"]; //I have instantiated using storyboard id.
[container setLeftMenuViewController:leftSideMenuViewController];
[container setCenterViewController:navigationController];
In Your controller.m add:
- (IBAction)menuPressed:(id)sender
{
[self.menuContainerViewController toggleLeftSideMenuCompletion:nil];
}
- (MFSideMenuContainerViewController *)menuContainerViewController
{
return (MFSideMenuContainerViewController*)self.navigationController.parentViewController;
}
Put this code into your AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// init center, left, and right view controllers
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:centerViewController]
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
return YES;
}
I encounter a problem using UITabBarItem and UIButton in my application. My button is inside a UITabBarItem. When I press it I want to be pushed to another controller to display a PDF.
Here is a piece of code that works in other cases :
- (void)viewDidLoad {
UIImage* imageButton = [UIImage imageNamed:#"pdf-button.png"];
UIButton *buttonPDF = [UIButton buttonWithType:UIButtonTypeCustom];
buttonPDF.frame = CGRectMake(SCREEN_WIDTH/2 - 100, 100, 200, 36);
[buttonPDF setImage:imageButton forState:UIControlStateNormal];
buttonPDF.contentMode = UIViewContentModeScaleAspectFit;
buttonPDF.contentHorizontalAlignment = UIControlContentHorizontalAlignmentFill;
[buttonPDF addTarget:self action:#selector(displayPDFParams:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:buttonPDF];
}
-(void)displayPDFParams:(UIButton *)sender {
PDFProduitController *pdfController = [[PDFProduitController alloc] init];
pdfController.pdf = documentParametres;
[self.navigationController pushViewController:pdfController animated:YES];
}
displayPDFParams is called but it not push me on my pdfController. I think it's because I'm not able to target the parent navigation controller of my application...
Anyone help would be much appreciated. Thanks in advance !
You need To initialize your root view controller with the navigation controller. Here is the code.
In your AppDelegate.h
#import <UIKit/UIKit.h>
#import "HomeViewController.h"
#class HomeViewController;
#interface IDSAppDelegate : UIResponder <UIApplicationDelegate>{
UINavigationController *nav;
}
#property (strong, nonatomic) HomeViewController *homeViewController;
#end
In your AppDelegate.m
#import "IDSAppDelegate.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.homeViewController = [[HomeViewController alloc] initWithNibName:#"HomeViewController" bundle:nil];
nav=[[UINavigationController alloc]initWithRootViewController:self.homeViewController];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
Problem solved by define a property in my UIViewController (as UITabBarItem) like this :
#property (nonatomic, retain) UINavigationController *superNavController;
And set it in my UITabBarController :
self.myViewController.superNavController = self.navigationController;
Finally I modified my displayPDFParams method :
-(void)displayPDFParams:(UIButton *)sender {
PDFProduitController *pdfController = [[PDFProduitController alloc] init];
pdfController.pdf = self.documentParametres;
[self.superNavController pushViewController:pdfController animated:YES];
}
Works perfectly !
I'm trying to use a navigation controller in my iOS-Project. Here is the setup of my AppDelegate class:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Generate RootViewController (some auto-layout stuff is going on here)
MyLayoutDescriptionGeneratorClass *generator = [MyLayoutDescriptionGeneratorClass new];
MyViewControllerClass *vc = [generator generateViewController];
self.navController = [[UINavigationController alloc] initWithRootViewController:vc];
[self.window setRootViewController:self.navController];
[self.window makeKeyAndVisible];
return YES;
}
The viewDidLoad of my view controller looks like this:
-(void)viewDidLoad{
[super viewDidLoad];
// Generate all subviews and their constraints
self.view = [MyObjectManagerClass viewForParentViewDescription:_parentViewDescription];
self.title = #"Hello";
}
When I Build & Run the navigation bar is shown and its title is set to Hello - unfortunately the view controllers view is not displayed.
If I take out the navigation controller like this
[self.window setRootViewController:self.navController];
everything works great. Can anyone help me please?
I just had to modify my viewDidLoad:
-(void)viewDidLoad{
[super viewDidLoad];
// Generate all subviews and their constraints
UIView *view = [RuiObjectManager viewForParentViewDescription:_parentViewDescription];
self.title = #"Hello";
// Add generated view to self.view and create constraints
[self.view addSubview:view];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"H:|[view]|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(#"view", view)]];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"V:|[view]|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(#"view", view)]];
}
I'm trying to change the viewcontroller's color.
Someone let me know like following.
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];
}
Here is AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[[ViewController alloc] init] autorelease];
} else {
self.viewController = [[[ViewController alloc] init] autorelease];
}
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
This is ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
But, result is that viewcontroller is black screen.
How to change to settings backgroundcolor?
try this
self.view.backgroundColor=[UIColor clearColor];
