I have a button in a viewcontroller that loads a motherViewController. This seems to be working correctly but for some reason the newly introduced view is so tall that the content at the bottom of are cropped.
- (IBAction)LoginButton:(UIButton *)sender
{
FirstViewController *FirstView = [self.storyboard instantiateViewControllerWithIdentifier:#"First"];
SecondViewController *SecondView = [self.storyboard instantiateViewControllerWithIdentifier:#"Second"];
ThirdViewController *ThirdView = [self.storyboard instantiateViewControllerWithIdentifier:#"Third"];
FourthViewController *FourthView = [self.storyboard instantiateViewControllerWithIdentifier:#"Fourth"];
FifthViewController *FifthView = [self.storyboard instantiateViewControllerWithIdentifier:#"Fifth"];
FirstView.Username = self.UsernameBox.text;
UINavigationController *FirstNavController = [[UINavigationController alloc]init];
[FirstNavController pushViewController:FirstView animated:NO];
UINavigationController *SecondNavController = [[UINavigationController alloc]init];
[SecondNavController pushViewController:SecondView animated:NO];
UINavigationController *ThirdNavController = [[UINavigationController alloc]init];
[ThirdNavController pushViewController:ThirdView animated:NO];
UINavigationController *FourthNavController = [[UINavigationController alloc]init];
[FourthNavController pushViewController:FourthView animated:NO];
UINavigationController *FifthNavController = [[UINavigationController alloc]init];
[FifthNavController pushViewController:FifthView animated:NO];
tabBar = [[UITabBarController alloc]init];
tabBar.viewControllers = [NSArray arrayWithObjects:FirstView, SecondView, ThirdView, FourthView, FifthView, nil];
[self.view addSubview:tabBar.view];
}
I don't whether i'm right or not. But here's the answer, you are trying to add UIViewController (UITabbarController) to your ViewController. So you need to position it in your view, for example
tabbar.view.frame = CGRectMake(0, 0, 320, 460);
But only thing i don't know its how it's perfectly positioned, when we are adding to window. Try your code by setting frame for your tabbarcontroller.
try this -
tabBar.tabBar.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;

I have pushed a view controller embedded in a navigation controller after tapping a button in my app. I am trying to add a "SAVE" button in the right corner of the nav bar. However, with this code it is not showing up. My assumption is that it is not showing up because nc.navigationItem.rightBarButtonItem should be placed in viewWillAppear. Since nc is programmatically created and does not have a class file with viewWillAppear how can I do this?
Here is my code:
- (IBAction)editProfileButtonTapped:(UIButton *)sender {
FXFormViewController *vc = [[FXFormViewController alloc] init];
vc.formController.form = [[PersonalContactInfoForm alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:vc];
nc.navigationBar.translucent = NO;
nc.navigationBar.barTintColor = [UIColor colorWithRed:(105/255.0)
green:(210/255.0)
blue:(231/255.0)
alpha:1.0];
// WHY IS THIS BUTTON NOT BEING ADDED?
nc.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Save" style:UIBarButtonItemStylePlain target:self action:nil];
[self presentViewController:nc animated:YES completion:nil];
}
The UINavigationController uses the -navigationItem of the currently displayed view controller. Try this instead:
vc.navigationItem.rightBarButtonItem = ...
Here you can take advantage of a powerful feature of OOP called Inheritance.
Create a Class say MyFXFormViewController inherited from FXFormViewController.
MyFXFormViewController.h
#import "FXFormViewController.h"
#interface MyFXFormViewController : FXFormViewController
#end
MyFXFormViewController.m
#import "MyFXFormViewController.h"
#implementation MyFXFormViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *saveBarButton = [[UIBarButtonItem alloc] initWithTitle:#"Save" style:UIBarButtonItemStylePlain target:self action:nil];
self.navigationItem.rightBarButtonItem = saveBarButton;
}
And your previous code should be like
- (IBAction)editProfileButtonTapped:(UIButton *)sender {
MyFXFormViewController *vc = [[MyFXFormViewController alloc] init];
vc.formController.form = [[PersonalContactInfoForm alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:vc];
nc.navigationBar.translucent = NO;
nc.navigationBar.barTintColor = [UIColor colorWithRed:(105/255.0)
green:(210/255.0)
blue:(231/255.0)
alpha:1.0];
[self presentViewController:nc animated:YES completion:nil];
}
I have this code in my appDelegate.m that implements a UINavigationController with a UITabBarController:
FristViewController *primeiro = [[FristViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc] init];
[nav1 pushViewController:primeiro animated:YES];
FilesViewController *segundo = [[FilesViewController alloc] init];
UINavigationController *nav2 = [[UINavigationController alloc] init];
[nav2 pushViewController:segundo animated:YES];
InfoViewController *terceiro = [[InfoViewController alloc] init];
UINavigationController *nav3 = [[UINavigationController alloc] init];
[nav3 pushViewController:terceiro animated:YES];
UITabBarController *tabbar = [[UITabBarController alloc] init];
tabbar.viewControllers = [NSArray arrayWithObjects:nav2, nav1, nav3, nil];
nav1.tabBarItem.image = [UIImage imageNamed:#"tab1.png"];
nav2.tabBarItem.image = [UIImage imageNamed:#"tab2.png"];
nav3.tabBarItem.image = [UIImage imageNamed:#"tab3.png"];
self.window.rootViewController = tab bar;
It's all right with this code, in my case when I beginning my app appearing on the first controller is FilesViewController because it is the first in the order of Tab Bar, but in my case I would like the first controller was the FristViewController without changing the order of items in the tab bar, how can I do this?
Go to your storyboard or xib where you created your TabBar. Drag the First controller to 1st position. Or programmatically you could set tabBar.selectedIndex = 0;
I want to create the same popover for my iPhone app with size GGrect of (320 100.0).
Here is my old code:
View * pk1 = [[View alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:pk1];
pop = [[UIPopoverController alloc] initWithContentViewController:nav];
[pop setDelegate:self];
[pop presentPopoverFromRect:[self btnsavepart].frame inView:[self view] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[nav release];
I using this codes but its doesn't change
nav.preferredContentSize = CGSizeMake(320, 100);
I can not change UIpopovercontriller with UIPopoverPresentationController.
How do I specify GGrect of (320 100.0)?
i thinks i can change only on horizontally but how can i do.
View *viewController = [[[View alloc] init] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:viewController] autorelease];
navController.modalPresentationStyle = UIModalPresentationPopover;
navController.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionUp;
navController.popoverPresentationController.sourceRect = btnsavepart.bounds;
navController.popoverPresentationController.sourceView = btnsavepart;
navController.popoverPresentationController.delegate = self;
[self presentViewController:navController animated:YES completion:nil];
i want the UIPopoverPresentationController not FullScreen form in iPhone
i adding this codes but i give the FullScreen view
- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller
{
return NO;
}
I work with Xamarin but its same thing , to specify size of the popover in which you want to display your UIViewController, in the properties of your UIVIewController you have the PreferredContentSize property. There you specify the size.
I saw it somewhere here but forgot where.
How can I swap the view of my MAAttachedWindow with the window visible?
defaultViewController = [DefaultViewController alloc] initWithNibName:#"DefaultView" bundle:nil];
attachedWindow = [[MAAttachedWindow alloc] initWithView:[defaultViewController view]
attachedToPoint:point
inWindow:nil
onSide:MAPositionBottom
atDistance:25.0];
How would I swap in AnotherViewController's view?
After a good night's sleep, it took 5-minutes to figure this out!
NSViewController *vc = [[NSViewController alloc] initWithNibName:#"MainView"
bundle:nil];
view = vc.view;
[vc release];
// Setup firstViewController here, addSubview and set current = firstViewController.view
attachedWindow = [[MAAttachedWindow alloc] initWithView:view
attachedToPoint:pt
inWindow:nil
onSide:MAPositionBottom
atDistance:5.0];
Then in my swap view method, simply:
-(void)swapView
{
SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:#"SecondView" bundle:nil];
// Resize our host view
[view setFrameSize:secondViewController.view.frame.size];
// Replace the current view
[view replaceSubview:current with:secondViewController.view];
// Resize our attachedWindow
[attachedWindow setFrame:secondViewController.view.frame display:YES];
[secondViewController release];
[current release];
}
I create a UIViewController (a custom calendar and its size is 550x440) and when i push a button it must be appear; the problem is that if I use setModalPresentationStyle and setModalTransitionStyle they change size of my view; can I set the size for these presentation?
I find a solution:
[self presentModalViewController:calendar animated:YES];
calendar.view.superview.frame = CGRectMake(0, 0, 200, 200);
Maybe you want to change your design to implement your calendar as a popover:
// Define the size of the calendar view controller for the popover
UIViewController *viewController = [[UIViewController alloc] init];
viewController.contentSizeForViewInPopover = CGSizeMake(550.0f, 440.0f);
viewController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
// Create the popover
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:navigationController];
// Present the popover from one button
[popoverController presentPopoverFromBarButtonItem:button permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
//release the popover content
[viewController release];
[navigationController release];
