how to push UIImagePickerController into UINavigationController? - iphone

Question

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.....

Answer 1

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.

Answer 2

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.

Answer 3

If using GKImagePicker:
[self.view addSubview:self.imagePicker.imagePickerController.view];

Answer 4

You can always do:
let cam = UIImagePickerController()
cam.delegate = self
cam.sourceType = .camera
self.show(cam, sender: nil)
worked for me

Answer 5

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!
