I'm solving the status bar issue in iOS 7 using
if(st.version == 7)
{
CGRect screen = [[UIScreen mainScreen] bounds];
CGRect frame = self.navigationController.view.frame;
frame.origin.y = 20;
frame.size.height = screen.size.height - 20;
self.navigationController.view.frame = frame;
}
Since I'm using navigation controller and pushing from one to another using [self.navigationController pushViewController:newone animated:YES];. It works fine in all view controllers. But, if the viewcontroller has mkmapview in xib, status bar issue of ios 7 occurs.
If I delete the mapview form xib and push to that view controller means, it will be like,
If I add the mapview even by code below,
mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 100, 320, 100)];
[self.view addSubview:self.mapView];
It looks like,
How to solve this?
if(st.version == 7){
mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 120, 320, 100)];
}else{
mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 100, 320, 100)];
}
If you add mapView in viewWillAppear replace it in viewDidAppear.
Maybe you have this issue because you're doing manipulations with view's frames before your view is completely set up
I would highly suggest against doing it like that.
If you're using interface builder, then add constraints based on how you want your application to look and the frame will auto adjust itself.
If you're not using interface builder, then still use constraints, but get a good tutorial about making constraints programatically (as I don't know how to do it myself).
Edit: The reason I HIGHLY suggest not doing it with hardcoded numbers is that it'll be a pain to do iOS 6/7 Landscape/Portrait 3.5/4 inch screens. That's 8 cases.
i think you have some adjust your navigation Y position set -20px. that way it goes overlay. use this code your ViewController
CGRect screen = [[UIScreen mainScreen] bounds];
CGRect frame = self.navigationController.view.frame;
frame.origin.y =0;
frame.size.height = screen.size.height;
self.navigationController.view.frame = frame;
or may it you have use wantFullScreenLayout some where in your project
setWantsFullScreenLayout = YES:
statusbar section is located to the (0,0) point to catch.
Statusbar and as large as the size of the current view to increase the value of mainScreen change the size of the bounds.
Statusbar change the style of the translucent style.
this below link you get some clear idea about your issue
How do I get the navigation bar in a UINavigationController to update its position when the status bar is hidden?
Override the -edgesForExtendedLayout method in your view controller
-(UIRectEdge)edgesForExtendedLayout {
return UIRectEdgeNone;
}
If you want to hide status bar from a particular view add this method in that particular view.m file
- (BOOL)prefersStatusBarHidden
{
return YES;
}
What about setting self.automaticallyAdjustsScrollViewInsets = NO; in viewDidLoad of your view controller or in IB?
Try to set MapView(ScrollView) automaticallyAdjustsScrollViewInsets = NO;
Try to set edgesForExtendedLayout to UIRectEdgeNone;
Try to use UIViewController.topLayoutGuide, see the Q&A from apple about this issue:Preventing the Status Bar from Covering Your Views.
Try to use the bar position delegation, see UIBarPositioningDelegate Protocol Reference
According to your description and screenshots, you are trying to move the whole UINavigationController.view.frame 20 pt, and the MapView(ScrollView) did something to prevent it happened (or re-set), put some breakpoint and log to track the frame of UINavigationController.view.frame changed.
Could you please provide a sample project? I'm so curious about what really happened.
try this
- (void)viewWillAppear:(BOOL)animated
{
self.navigationController.navigationBar.translucent = NO;
}
- (void)viewDidAppear:(BOOL)animated
{
self.navigationController.navigationBar.translucent = YES;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[application setStatusBarHidden:YES];
return YES;}
Please add this line to your code.This will hide the status bar from your app.
If you have a xib. Did you try to enabled Top Bar in simulated Metrics ?
I am creating a view programmatically. The view is fairly simple as it only contains an MKMapView which I want to fill the screen (with the exception of the navigation bar at the top).
Here is what I am doing to setup the MKMapView:
- (void)setupMapView
{
mapView = [[MKMapView alloc] initWithFrame:self.view.frame];
mapView.delegate = self;
mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
[self.view addSubview:mapView];
}
However, the MKMapView doesn't seem to fill the entire screen. If you look at the top of this screenshot there is a gap between the top of the map and the bottom of the navigation bar (which is added by the UINavigationController).
Please could someone suggest why this is happening and how I can fix it?
The frame of the view (self.view.frame) probably have an offset in the y position. This is to position it correctly in its superviews coordinate space. When you copy that frame onto your new view it is inappropriate because you are moving into a different coordinate space.
A cheap alternative that will work in 99.9% or cases is to use the view bounds instead:
mapView = [[MKMapView alloc] initWithFrame:self.view.bounds];
Because this usually has an origin of zero and the full size of the view.
I have a Scrollview, it's properties are set in viewDidAppear.
Now when I get to the Scrollview first time there isn't any problem. However I have buttons that are assigned to UINavigationController. So when I press into one of them UINavigationController opens up, when I close the navigation controller, ScrollView does not restore properly. It basically aligns the centre of the screen as previously pressed button location. So if I try to scroll up it does not.
I have tried using this in my viewDidAppear:
scrollView.center = CGPointMake(scrollView.contentOffset.x, scrollView.contentOffset.y);
Which did not quite work. How can I solve this? I am using iOS6.1
Actually I found the answer here:
UIScrollview Autolayout Issue
The exact code that I used is:
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
//save the current offset
previousPoint = scrollView.contentOffset;
//set current view to the beginning point
self.scrollView.contentOffset = CGPointZero;
}
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
//retrieve the previous offset
self.scrollView.contentOffset = previousPoint;
}
previousPoint is nothing but a CGPoint variable declared on the implementation.
I've had this problem before too. This answer shows how to overcome this issue.
Basically, you need to set the scrollview's contentOffset appropriately in viewWillAppear: and viewDidDisappear:.
EDIT: Here's another related question that you might find useful, UIScrollview Autolayout Issue.
Hi I was learning how to use autoresizing and scroll view also and came up with this solution which works, just your feedback would be welcome on my approach if it is ok how it could be improved etc.
I just created a test view controller whose view looks like this.
The grey area is a UIView called mainView and it is subview of view controller's view (and it's longer than view controller's view).
When I changed rotation one would see such thing:
You can see the calculator does not fit on the screen anymore.
So I decided to have a UIScrollView already from start. Add mainView as a subview to it.
Final thing that was remaining, I wanted the frame of the ScrollView to change also when device rotates, so that I could get such effect:
(you see the scroll views width is same as phones).
This is how I implemented all this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:[self.view bounds]];
[[self view] addSubview:scrollView];
[scrollView addSubview:self.mainView];
[scrollView setContentSize:[mainView bounds].size];
[scrollView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleRightMargin |UIViewAutoresizingFlexibleBottomMargin];
}
Any comments and feedback?
You can use the didRotate methods to position your buttons how you want in the different orientations. There is a good tutorial here: http://www.youtube.com/watch?v=f3yb24f8O1Y&list=PL53038489615793F7
I add a custom view to my UIViewController dynamically. It adds perfectly now, no exception.But the screen is stuck. My scrollview is not functional. I got this problem earlier and people suggested use setContentSize. I did that and it worked fine. Now I have a new scenario.I have 2 screens.In screen A i save values .Then i click a bar button item on screen A and go to screen B. Here in screen B (it's a tableviewcontroller) I select one row and go back to screen A and fill the values accordingly (basically load the saved values that I saved in the beginning of the app). I fill them correctly and also add the scroll view but it is stuck.It doesn't move neither up/down. I have this code written for adding the subview and setting the scroll-view size and frame size.
ITMCustomView *cView = [[ITMCustomView alloc] initWithFrame:CGRectMake(187, 660, 400, 400)
andOrderedItem:#"New"
andTag:self.tagNumber
withFoldArray:self.foldTypeArray
withRollArray:self.rollTypeArray];
cView.tag =self.tagNumber;
NSLog(#"Assigned tag is %d",cView.tag);
cView.delegate = self;
CGPoint scrollPoint = CGPointMake(0.0, (cView.frame.origin.y/500)*400);
[self.scrollView setContentOffset:scrollPoint animated:YES];
[self.scrollView addSubview:cView];
CGFloat scrollViewHeight = 0.0f;
for (UIView *view in self.scrollView.subviews)
{
scrollViewHeight += view.frame.size.height;
}
CGSize newSize = CGSizeMake(320,scrollViewHeight);
[self.scrollView setContentSize:newSize];
NSLog(#"947 the tag number is %d",self.tagNumber);
I check the value of scrollViewHeight..its 3254.000..I changed it to say 4000 as someone suggested increasing height worked. So what am i doing wrong. This question follows another question of mine Navigating back to UIViewController from TableViewController using NSNotifications
If you need more info please ask.Thanks.
Got mine working after I used did appear instead of will appear.
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
self.scrollView.contentSize = self.viewMain.bounds.size;
}
Check the scrollingEnabled property on the scroll view. Unsurprisingly, it needs to be set to YES. If this is the case and it still doesn't work, check if the view (and its superviews) has userInteractionEnabled set to YES as well. In the debugger, you can do po [self.view recursiveDescription] to get the view hierarchy back, that may give you some helpful information as well.
