Añadir botón a la barra de navegación mediante programación
Hola Necesito configurar el botón en el lado derecho, en la barra de navegación, programáticamente , de modo que si presiono el botón realizaré algunas acciones. He creado la barra de navegación, programáticamente por;
navBar=[[UINavigationBar alloc]initWithFrame:CGRectMake(0,0,320,44) ];
Del mismo modo, necesito agregar el botón, en el lado derecho de esta barra de navegación. Para eso usé,
1.
UIView* container = [[UIView alloc] init];
// create a button and add it to the container
UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 130, 44.01)];
[container addSubview:button];
[button release];
// add another button
button = [[UIButton alloc] initWithFrame:CGRectMake(160, 0, 50, 44.01)];
[container addSubview:button];
[button release];
// now create a Bar button item
UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithCustomView:container];
// set the nav bar's right button item
self.navigationItem.rightBarButtonItem = item;
[item release];
2.
UIImage *im;
im=[UIImage imageNamed:@"back.png"];
[button setImage:im forState:UIControlStateNormal];
[im release];
backButton = [[UIBarButtonItem alloc] initWithCustomView:button];
[backButton setImageInsets:UIEdgeInsetsMake(0, -10,5, 5)];
[self.navigationItem setRightBarButtonItem:backButton];
3.
UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithTitle:@"button" style:UIBarButtonItemStylePlain target:self action:@selector(refreshLogsAction:)];
self.navigationItem.rightBarButtonItem = refreshItem;
[refreshItem release];
Probé todas estas formas, pero ninguna muestra el botón en el lado derecho.

Dentro de mi clase derivada UIViewController
, estoy usando lo siguiente dentro de viewDidLoad
:
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
initWithTitle:@"Flip"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(flipView:)];
self.navigationItem.rightBarButtonItem = flipButton;
[flipButton release];
Esto agrega un botón a la derecha con el volteo de título, que llama al método:
-(IBAction)flipView
Esto se parece mucho a ti #3, pero está funcionando dentro de mi código.

Simple use editBarButton nativo como este
self.navigationItem.rightBarButtonItem = self.editButtonItem;
[self.navigationItem.rightBarButtonItem setAction:@selector(editBarBtnPressed)];
Y luego
- (void)editBarBtnPressed {
if ([infoTable isEditing]) {
[self.editButtonItem setTitle:@"Edit"];
[infoTable setEditing:NO animated:YES];
}
else {
[self.editButtonItem setTitle:@"Done"];
[infoTable setEditing:YES animated:YES];
}
}
Diviértete...!!!

Si no está buscando un barButtonItem sino un botón simple en la barra de navegación, el siguiente código funciona:
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:[UIImage imageNamed:@"NavBar.png"] forState:UIControlStateNormal];
[aButton addTarget:self
action:@selector(showButtonView:)
forControlEvents:UIControlEventTouchUpInside];
aButton.frame = CGRectMake(260.0, 10.0, 30.0, 30.0);
[self.navigationController.navigationBar addSubview:aButton];

Hola a todos !! Creé la solución al problema en cuestión donde se quieren dos orientaciones UIInterface utilizando el UIImagePicker.. En mi ViewController donde manejo el segue al UIImagePickerController
* * Uso a..
-(void) editButtonPressed:(id)sender {
BOOL editPressed = YES;
NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
[boolDefaults setBool:editPressed forKey:@"boolKey"];
[boolDefaults synchronize];
[self performSegueWithIdentifier:@"photoSegue" sender:nil];
}
**
Luego en la clase AppDelegate hago lo siguiente.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
BOOL appDelBool;
NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
appDelBool = [boolDefaults boolForKey:@"boolKey"];
if (appDelBool == YES)
return (UIInterfaceOrientationMaskPortrait);
else
return UIInterfaceOrientationMaskLandscapeLeft;
}
