CGRect rect = CGRectMake(0, 0, 1050, 900);
[wineAdminPopup presentPopoverFromRect:rect inView:master.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
Hi I put the above code to make a popup in a tableview. However it doesn't popup in the whole screen. If I want to center it in the iPad screen with no arrow or arrow in the center. How can i do it. Thanks in advance.
The rect parameter in presentPopoverFromRect:... specifies the rectangle at which to anchor the popover, not the size of the presented popover. That would be specified by setting contentSizeForViewInPopover on the popover's content view controller.
If you don't want the arrows and don't need the specific behavior of popovers, then you could
present your view controller modally:
controller.modalPresentationStyle = UIModalPresentationFullScreen; // or UIModalPresentationFormSheet
[self.navigationController presentModalViewController:controller animated:YES];
presentModalViewController is deprecated in iOS 6 and above. Use presentViewController:yourViewController animated:YES completion:nil (parameters animated and completion can be set depending on your requirements). Also if you want to resize yourViewController you need to change self.view.frame and next time your view controller will be of that size.

I have some subviews that I place inside each of my tab bar's view controllers. Right now I'm sizing it with a pixel count but it only works on the iPhone 4 and 4s and not the iPhone 5 because of the longer screen size. I could check for the device and then size it that way but I feel like there has to be an easier way to do this.
viewController1.view.frame = CGRectMake(0, 0, 320, 460);
I colored the subview yellow so it's easier to see.
You should NOT change frame of tabbar's content view controller's view. UITabBar takes itself care of sizing the child view controller's frame properly.
If you want to add subview to content view controller (controller under some tab) and make that view to always automatically resize with the controllers main view (self.view), you can use combination of superviews frame and autoresizing.
Example code (you can do this in - (void)viewDidLoad for example):
UIView *view = [[UIView alloc] initWithFrame:self.view.bounds];
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:view];
If you want to do this by setting frame than DO this:
[childView setFrame:childView.superview.bounds];
The master view in your view controller should already be the size of the usable space on the sceen. In general, if you want a view to be the same size as it's parent, you can use view.frame = view.superview.frame, though I doubt that would be a good idea to call on the view controller's view.
I am using UIPopover to display videos using UIImagePickerController.In this I have to dismiss my popover when use is clicked.Can anyone please help me to do this?
Also I want to change the size of the popover.Now I am using the below code to chane the size.But it is not working.Width is not getting changed.
[popOver1 setPopoverContentSize:CGSizeMake(1000.0 , 500.0) animated:YES];
Please give me a solution for these two problems..
For dismissing popover controller you can use below code in button action method.
[popoverController dismissPopoverAnimated:YES];
For changing the width you can change the frame of the popover controller not contentSize.
popoverRect = CGRectMake(x, y, width,height);
i found you are trying like this
[popOver1 setPopoverContentSize:CGSizeMake(1000.0 , 500.0) animated:YES];
//it means in increases the contentSize not the width
I'd like to present a UIPickerView snapped to the bottom of a UITableView regardless of where it is scrolled.
Currently I have a UIPickerView added to a UITableView that I present when a button is pressed, but when I scroll the table the UIPickerView goes out of view, and if I'm scrolled out of range of where I've presented it, the UIPickerView appears to have never been called.
Does anyone know how to accomplish this?
Thank
The use of UITableViewController is great unless you need to add subview that don't scroll with the table view. It can't really be done. The solution is to use a UIViewController instead and add your own table view, setup the table view dataSource and delegate protocols and replicate the basic table view controller plumbing.
Once your view controller works like a normal table view controller again, you can now add subviews to the view controller's view that won't scroll with the table.
if u add tableview programatically
SearchtableView.frame = CGRectMake(450, 90, 318, 600);
SearchtableView = [[UITableView alloc] initWithFrame:CGRectMake(623, 90, 400, 400)style:UITableViewStyleGrouped];
[self.view addSubview:SearchtableView];
//belove the tableview//
//Add UIPickerView to the self.view]//
Something told me that there must be a simpler alternative to the answers that I'd been given, and I found a solution.
I decided to find the y coordinate of the scroll point using scrollViewDidScroll: and then animating the UIPickerView to the desired location.
...
[UIView beginAnimations:nil context:NULL];
CGFloat pointY = self.scrollPoint.y;
[self.sortPicker setFrame:CGRectMake(0, pointY + 200, 320, 216)];
[UIView commitAnimations];
...
The UIPickerView will only appear if the scroll has been stopped so it's necessary to implement a method to stop the scroll on touch:
- (void)stopScroll:(UITableView *)tableview
{
CGPoint offset = tableview.contentOffset;
[tableview setContentOffset:offset animated:NO];
}
This will allow you to display and dismiss the UIPickerView at any moment at any given destination.
I have UIButton on view, when I taped on this button I want to create new view and display it on iPad screen, how I can view this view like growing from button to full screen ?
Next time actually show some effort with what you have tried etc when asking for help
- (void)buttonTapped:(UIButton *)button;
{
UIView *expandingView = [[UIView alloc] initWithFrame:button.frame];
expandingView.backgroundColor = [UIColor redColor];
[self.view addSubview:expandingView];
[UIView animateWithDuration:.25f
animations:^{
expandingView.frame = self.view.bounds;
}];
}
On the button click event.
Create the view with frame with size zero and orgin as center of
button
2.add to mainview
3.Then using animation block change
the frame to orginal
What are block-based animation methods in iPhone OS 4.0?
use this qn to find how to add animation
Is there any model view like this on the iPad?
Yes, there is:
UIModalPresentationFormSheet
The width and height of the presented view are smaller than those of the screen and the view is centered on the screen. If the device is in a landscape orientation and the keyboard is visible, the position of the view is adjusted upward so that the view remains visible. All uncovered areas are dimmed to prevent the user from interacting with them.
For example:
UIViewController *viewController = [[UIViewController alloc] init];
viewController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:viewController animated:YES];
viewController.view.superview.frame = CGRectMake(0, 0, 540, 500); // this is important to do this after presentModalView
viewController.view.superview.center = self.view.superview.center;
