I am trying to hide the navigational bars according to the cursor positions.so, that I can use the full screen of the iPhone. But I donno how to start it.
Similar (less confusing :) ) question: Show/hide UIToolbar, "match finger movement", precisely as in for example iOS7 Safari
Use the below code if you want to hide and unhide the navigation bar on double tap on any part of the view
In your .h file:
IBOutlet UINavigationController *navigationController;
Connect the IBOutlet in your XIB.
in your .m file:
-(void)viewDidLoad {
[super viewDidLoad];
[navigationController setNavigationBarHidden:YES];
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject];
if (touch.tapCount == 2) {
[navigationController setNavigationBarHidden:NO];
[NSTimer scheduledTimerWithTimeInterval:(1.0) target:self selector:@selector(hideBar) userInfo:nil repeats:NO];
}
}
-(void)hidebar{
[navigationController setNavigationBarHidden:YES];
}
Do the modifications as per your requirement.
Happy coding!
There is no cursor on iPhone, but do you mean that you want to do something like safari - hide the address bar when scroll down more than one screen page?
Assume that you are using UITableView, I have a solution that: 1. we are already know height of each table row -> cell.frame.size.heigh 2. and we already know height of screen -> view.bounds.size.height 3. UITableView call cellForRowAtIndexPath every time it generate a cell So you can easily know how many cells are there in you table, row index and total height of them, whenever you see a row index which belong to next screen page, you should hide navigation bar with an animation. otherwise, if all row index are belong to 1st screen -> show navigation bar with animation.
