I have this code to load an NSView from a NIB and add it to another NSView:
// INIT
- (void)awakeFromNib {
// Load nib
DNListViewController *listViewController = [[DNListViewController alloc] initWithNibName:#"ListView" bundle:nil];
// Add view to window
[listViewController.view setFrame:detailView.frame];
[detailView addSubview:listViewController.view];
// MEM
[listViewController release];
}
All outlets are connected right, but nothing shows up. I don't understand why! Can someone help me? Thanks.
This is about NSViews, not UIViews!
Oh, I fixed it already. Nevermind, I'll let is stay here for people from the future.
[listViewController.view setFrame:detailView.frame];
must be
[listViewController.view setFrame:detailView.bounds];

I just have one question related to presenting a from sheet view controller in iOS 8. In iOS 7 I was able to change the height of the view controller using the last line of code in the function below:
SendRemainingEvaluationsViewController *sendRemainingEvaluationViewController = [[[SendRemainingEvaluationsViewController alloc] initWithNibName:#"SendRemainingEvaluationsViewController" bundle:nil]autorelease];
UINavigationController *navigationController = [[[UINavigationController alloc] initWithRootViewController:sendRemainingEvaluationViewController] autorelease];
navigationController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
navigationController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:navigationController animated:YES completion:nil];
//To Change the default size of the viewController which is presented in UIModalPresentationFormSheet presentation style
navigationController.view.superview.frame = CGRectMake(navigationController.view.superview.frame.origin.x, navigationController.view.superview.frame.origin.y, navigationController.view.superview.frame.size.width, 230);
But this does not work on iOS 8, not sure why? Does anyone knows what is the problem? any idea will be appreciated.
Thanks in advance.
After checking it, I could figure out the problem. After initializing the view navigation controller, its superview is nil and you can't access it right after presenting it. As a workaround, you can change the frame of its superview in the viewwillAppear of the view controller you're trying to present as you can see below:
- (void) viewWillAppear:(BOOL)animated
{
self.parentViewController.view.superview.frame = CGRectMake(self.parentViewController.view.superview.frame.origin.x, self.parentViewController.view.superview.frame.origin.y, self.parentViewController.view.superview.frame.size.width, 230);
}
This should work.
Apologies if this is a basic question but I am new to Xcode and have a storyboard app and in the storyboard (with no segue) I have a view controller with an embedded map view.
On the storyboard screen I have an image with a tap gesture linked, I have tested the tap and it works (NSLog) but I want to know how to launch my mapview view controller and also zoom to an x&y.
My code currently has
-(IBAction)handleMapTap:(UIGestureRecognizer *)sender {
NSLog(#"Tapped");
}
& I have tried;
MMMapViewController *mapViewController = [[MMMapViewController alloc] initWithNibName:#"MapView" bundle:nil];
[self.navigationController pushViewController:mapViewController animated:YES];
My view controller has a class set as MMMapViewController I have given the view controller a storyboard id of MapView (if it's required?).
I've read a lot of stackoverflow articles but can't seem to find an answer. If anyone can help I would be really grateful.
-(IBAction)handleMapTap:(UIGestureRecognizer *)sender
{
MMMapViewController *mapViewController = [[MMMapViewController alloc] initWithNibName:#"MapView" bundle:nil];
//[self.navigationController pushViewController:mapViewController animated:YES];
[self presentModalViewController:mapViewController animated:YES];
[mapViewController release];
}
It would probably help to know what self is, if it is indeed a UIViewController, then
I would make sure that self.navigationController is not nil.
You actually have the right code, as far as I can tell, but depending on your scenario, you could get away with presenting the mapView as a modal view controller.
Ok, it's 3 am atm and I haven't a clue where I put this:
[navigationController.navigationBar setTintColor:[UIColor redColor];
If you would please post the whole .m/.h files that would be great. Also, do I connect anything using segues or outlets? And when you create the .h/.m files do I need UINavigationController or similar selected or just the normal UIViewController? Thanks.
Update: Nevermind I got it, thanks though. Below is the code for others having my issue.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
UINavigationBar *bar = [self.navigationController navigationBar];
[bar setTintColor:[UIColor lightGrayColor]];
}
Basically just add on to what's already there.
I feel stupid lol.
You can set that value right after you init your UINavigationController, i.e:
UINavigationController *controller = [[UINabvigationController alloc] initWithRoot...
[controller.navigationBar setTintColor:[UIColor redColor]];
So basically I have this project, where I have 4 different tab bar pages. 2 of them uses navigation controller & tab bar, and 2 are just view controllers. Now there is this one viewcontroller, which I need to add a scroll view to. So basically, I click on the item in the tab bar, it takes me to a view controller, where I can scroll down and up. I have been following Youtube Video Link, but I do not get it to work. The problem is that I use the exact code, and I change the ViewController class to the .h and .m name (ScrollViewViewController), and I put in a scroll view that has 320 x 1000, and a button at the top, but it doesn't scroll! How can I solve this problem?
Note: That if you don't know my problem, but could very detailed walk me through on how to add a scroll view to storyboards in xcode 4.2, then that would be amazing :)!
scrollerViewController.m:
- (void)viewDidLoad {
[scroller setScrollEnabled:YES];
[scroller setContentSize:CGSizeMake(320, 1000)];
[super viewDidLoad];
}
scrollerViewController.h
#interface scrollerViewController : UIViewController {
IBOutlet UIScrollView *scroller;
}
#end
And here comes a picture of the storyboard.
I need some of the code in order to really know your problem, but let me throw in my guess. You may be setting the size 320x1000 to the frame size of the scrollview by any chance? The frame size of the scrollview has to stay 320x480, and the contentSize should be 320x1000. Sorry if it was a wrong guess, but shouldn't do any harm :)
Something like this in your ViewController of the scrollView...
- (void) viewDidLoad {
[super viewDidLoad];
UIScrollView * scrollView = self.view;
scrollView.frame = (CGRect){scrollView.frame.origin, CGSizeMake(320, 480)};
scrollView.contentSize = CGSizeMake(320, 1000);
scrollView.backgroundColor = [UIColor whiteColor]; // I am setting the white background, so that the scroll indicator is visible
}
I am assuming you are setting ScrollView as the top view of the ViewController in your Storyboard as in the attached image.
I followed the exact same movie and it did not work for me either. But this movie did: http://www.youtube.com/watch?v=YBlwepYK7Zs
I followed that one and now i got it to work.
A bit late but might be more people looking for a solution to this.
Hi
Is there a way to remove a view from another view of a specific class?
What I mean I have a view with multiple other views like a scrollview, imageview, tableview and I only want to remove the scrollview.
I thought the code would be something like this:
for (UIView *view in self.view.superview.subviews) {
if ([view.class == [Class UIScrollView]]]) {
[view removeFromSuperview];
}
}
But this didn't work. I could work with object at index: but because we don't know what index the scrollview has,so it also won't work. (I think)
Does someone knows the answer to this problem?
Thank you very much!
Is it this what you mean?
for (UIView *view in self.view.superview.subviews) {
if ([view isKindOfClass:[UIScrollView class]] ) {
NSLog(#"class");
}
}
If you can set an IBOutlet to the subview just call removeFromSuperview on the saved outlet.
(log the outlet to make sure it's set properly if that doesn't work)
(pretty sure that applies to both NSView and UIView)
