I just followed one project for use pop up.But in that project the pop up view position is in centre.But i need to show pop up at top (i.e should show up in top with use half space of navigation bar)github project
I use UIViewController+ENPopUp.m UIViewController+ENPopUp.h JWBlurView.h JWBlurView.m files.I have changed all values .But not able to show pop up at top.i need to show pop up at this image position
But in that project the position is in centre. Knindly any one can help me out.I need show pop up at top Like this image
Thanks in advance !
Your question is not clear.I assume that you want to show pop at top of your viewcontroller instead of that project popup showing at centre.If so, then this is your solution:
I will explain with that github project that you post in your question.
you can change what ever you want in your own project. Go to ENViewController.m.And change the code to
- (IBAction)showPopUp:(id)sender
{
UIViewController *vc = [[UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil] instantiateViewControllerWithIdentifier:#"PopUp"];
vc.view.frame = CGRectMake(20, 30, 270.0f, 230.0f);
[self presentPopUpViewController:vc];
}
You can also change your popup viewcontroller size and update that size,height in this line on your showpopup action method:
vc.view.frame = CGRectMake(20, 30, Any size, Any height);
And if you want to change your postion of pop up view means .you can use any X , Y Values in this line on your showpopup action method:
vc.view.frame = CGRectMake(x, Y, Any size, Any height);
Then go to UIViewController+ENPopUp.m On under //Customize popUpView.delete one line(i have comment that).
// Customize popUpView
popUpView.layer.cornerRadius = 8.0f;
popUpView.layer.masksToBounds = YES;
popUpView.layer.zPosition = 99;
popUpView.tag = kENPopUpViewTag;
//popUpView.center = overlayView.center;
[popUpView setNeedsLayout];
[popUpView setNeedsDisplay];
[overlayView addSubview:popUpView];
[sourceView addSubview:overlayView];
Hope this helpfull.If not please ask your question clear .Let me know !

I have my app setup to show this view when it is loading data:
self.loadingView = [UIView new];
self.loadingView.frame = CGRectMake(0, 0, self.tableView.frame.size.width, self.view.frame.size.height);
self.loadingView.backgroundColor = [UIColor groupTableViewBackgroundColor];
[self.view addSubview:self.loadingView];
[self.view bringSubviewToFront:self.loadingView];
self.activityIndicator = [UIActivityIndicatorView new];
self.activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleGray;
self.activityIndicator.center = CGPointMake(self.view.frame.size.width / 2.0, self.view.frame.size.height / 2.0);
[self.view addSubview:self.activityIndicator];
[self.view bringSubviewToFront:self.activityIndicator];
[self.activityIndicator startAnimating];
Then, I remove it from its superview. It works on iPhone. It works on iPad sometimes too, except for when I'm using the same code in a UISplitViewController. I've tried various adjustments to centering the views, etc., but can't figure it out. What's going wrong?
I've add trouble with activity indicators in the past as well. Make sure you are not calling the startAnimating or stopAnimating while any animations are taking place. I recommend calling the startAnimating selector in viewDidLayoutSubviews.
The line where you set the center of the indicator looks like the source of the problem. self.view.frame.size is probably equal to screen size at this point and so when you show that view controller over the whole screen it's ok, but inside a split view controller it's not because indicator is off-bounds. You can check that from Xcode's Debug -> View Debugging -> Capture View Hierarchy (while the app is running).
Try setting activity indicator's center using autolayout and it should work.
I'm using TheSidebarController to implement add a sliding menu into an iOS application. This is the library I'm using, but I've found the same issue in other libraries, like ECSlidingViewController, etc. They essentially work by adding multiple view controllers onto a containing view controller, nothing too crazy.
The issue is, when you make the app a landscape app, all the screens in the container- the menu, the content screen- seem to think they're in portrait mode, and get cut off half way. You can see the issue in this screenshot where the table is cut off:
http://imgur.com/xD5MUei
I've been trying to get this to work in any way I can, and no luck.
The library I'm using + example project can be found here:
https://github.com/jondanao/TheSidebarController
Any help is greatly appreciated :)
EDIT: people are saying I can stretch the table out to make it look normal, but this just masks the underlying problem, which is the app and/or the screens still think they're in portrait orientation. As a quick example, if I take the example project, and in LeftViewController substitute the following code:
- (void)dismissThisViewController
{
UIViewController* vc = [[UIViewController alloc] init];
UINavigationController* pulldown = [[UINavigationController alloc] initWithRootViewController:vc];
pulldown.view.frame = CGRectMake(pulldown.view.frame.origin.x, -[[UIApplication sharedApplication] delegate].window.frame.size.height,
pulldown.view.frame.size.width, pulldown.view.frame.size.height);
[[[UIApplication sharedApplication] delegate].window addSubview:pulldown.view];
[UIView animateWithDuration:.5 animations:^{
pulldown.view.frame = CGRectMake(pulldown.view.frame.origin.x, 0,
pulldown.view.frame.size.width, pulldown.view.frame.size.height);
} completion:^(BOOL finished) {
;
}];
}
The viewcontroller comes in sideways, not from the top.
This was a strange one... I had to set the frame of the content view controller, which made sense, but then I had to reset it every time the content was refreshed:
- (void)setContentViewController:(UIViewController *)contentViewController
{
// Old View Controller
UIViewController *oldViewController = self.contentViewController;
[oldViewController willMoveToParentViewController:nil];
[oldViewController.view removeFromSuperview];
[oldViewController removeFromParentViewController];
// New View Controller
UIViewController *newViewController = contentViewController;
[self.contentContainerViewController addChildViewController:newViewController];
[self.contentContainerViewController.view addSubview:newViewController.view];
[newViewController didMoveToParentViewController:self.contentContainerViewController];
_contentViewController = newViewController;
if ([DeviceDetection isDeviceiPad]) {
_contentViewController.view.frame = CGRectMake(0, 0, 1024, 768);
}
}
Did you check if it's has something to do with the new interface orientation?

chapter -> Supporting New Screen Sizes and Scales
In CenterViewController.h make the class a subclass of a UITableViewController instead.
Then comment out [self.view addSubview:self.tableView]; in CenterViewController.m.
Done!
In centerViewController.m, when you create the tableview, add this line:
self.tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
I'm trying to create modalviewcontroller, which should look like this
My problem is in the close button. As you can see in this example it almost out of uiview.
I was tried uiview, who has close button, make transparent but when modalview opens it's still in light gray color.
There is bit of my code :
Settings *new = [[Settings alloc]init];
new.modalPresentationStyle = UIModalPresentationFormSheet;
//i was change to other presentation styles, but that no I want.
new.view.backgroundColor = [UIColor clearColor];
[self presentModalViewController:new animated:YES];
CGRect r = CGRectMake(self.view.center.x - 327,
self.view.center.y - 255,
630, 490);
r = [self.view convertRect:r toView:new.view.superview.superview];
new.view.superview.frame = r;
If you still don't understand, what I want there is ilustration of modal view I need:
What is your suggestion, how can I make it?
Basically what I am trying to figure out to do is, say I have one View Controller, called V1, that has a regular view inside it and a button. Now, when you tap that button, I want that button to create an action that pop-ups another View Controller, called V2, within the same view controller, V1.
V2 will be reduced in size some so that it does not fill the entire screen, but you can still see the first layer which is V1 behind V2. So basically, you never really leave V1. I hope this makes sense for what I'm trying to do. I know the MTV app has this functionity. An image of what I'm talking about is here: https://docs.google.com/leaf?id=0BzlCAVXRsIPcNWUxODM2MDAtNDE3OS00ZTc4LTk5N2MtZDA3NjFlM2IzNmZk&hl=en_US
Sample code or an example is what I'm looking for as well.
Thanks
You can create such view by setting appropriate property type of modalPresentationStyle. See my example below:
UIViewController *V2 = [[UIViewController alloc] init];
V2.modalPresentationStyle = UIModalPresentationFormSheet;
V2.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[V1 presentViewController:V2 animated:YES completion:nil];
V2.view.superview.frame = CGRectMake(0, 0, 540, 620); //it's important to do this after presentModalViewController
V2.view.superview.center = V1.view.center;
[V1 release];
Try this:
V2 *d = [[V2 alloc]initWithNibName:#"V2" bundle:nil];//assuming V2 is name of your nib as well
d.delegate = self; //Optional:you only need this if you want to delegate
//create popover and put V2 in the popover view
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:d];
popoverController.delegate = self; //optional
CGSize size = CGSizeMake(325, 75); // size of view in popover…V2
popoverController.popoverContentSize = size;
[d release];
[popoverController presentPopoverFromRect:yourButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
If you want to present this as a modal popup in iOS 8 with a similar style to the OP's screenshot here's what I did:
UIViewController *V2 = [[UIViewController alloc] init]; // V2 is the popup
V2.modalPresentationStyle = UIModalPresentationFormSheet;
V2.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
V2.preferredContentSize = CGSizeMake(325, 75); // size of popup view
[V1 presentModalViewController:V2 animated:YES]; // V1 is the current topmost view controller
I like this better than using a UIPopover because you don't need to mess with arrow directions and the user cannot close it by tapping outside of the popup.
These properties can also be set in a storyboard/nib via the designer. To set preferredContentSize check "Use Preferred Explicit Size" and set the values.
This only works on the iPad.
There is a very good library to display a view controller as Popup on iPhone
see here https://github.com/martinjuhasz/MJPopupViewController
If you're using Storyboard, you can follow this step:
Add a view controller (V2), setup the UI the way you want it
*based on the image you attached
add an UIView - set background to black and opacity to 0.5
add an UIImageView - that will serve as your popup (Pls take note that the image and the view must not have the same level/hierarchy. Dont make the imageview the child of the view otherwise the opacity of the uiview will affect the uiImageView)
Present V2 Modally
Click the segue. In the Attributes inspector, Set Presentation as Over Full Screen. Remove animation if you like
Select V2. In the Attributes inspector, Set Presentation as Over Full Screen. Check Defines Context and Provides Context
Select the MainView of your V2 (Pls. Check image). Set backgroundColor to Clear Color
file .m ---> this is the implementation file
-(IBAction)anyAlert:(id)sender{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"A Message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK!", #"Other Title", nil];
[alert show];
[alert release];
}
remember declare
-(IBAction)anyAlert:(id)sender;
in the file .h ---> header file
It works for me, hopefully for you...
Create UIView for v2 and add in v1.
- (void)viewDidLoad
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:#selector(aMethod:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[self.view addSubview:button];
}
- (void)aMethod:(id)sender
{
CGRect * imageFrame = CGRectMake(10, 90, 300, 300);
V2 *v2 = [[V2 alloc] initWithFrame:imageFrame];
[self.view addSubview:v2];
}
I am new to iphone development. What i have done here is, loading a view with a scroll view on which I m showing pictures.
I have got a basic navigation controller in the app..
Now, during the loading of picture if the picture is not fully loaded i want to add a MBProgressHUD..
I m using the following code for that but, not able to see the it infront of the scroll view although the hud is added on the view as i am unable to move the scroll View..
HUD = [[MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES] retain];
[[self.view superview] bringSubviewToFront:self.navigationController.view];
Any Suggestions please... Thanks for your help..
Assuming when you do:
HUD = [[MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES] retain];
You get an UIImageView, you can do something like:
[scrolView.view addSubView HUD.view];
HUD.frame=CGRectMake(x,y,width,height) //So you can specify where you want your image.
Building on RuiAAPeres's answer, here's some more complete code in Swift:
let frameHeight = self.tableView.frame.size.height
let frameWidth = self.tableView.frame.size.width
let hudHolderYCoord = frameHeight / 4 + self.tableView.contentOffset.y
let hudHolder = HUDHolderView(frame: CGRectMake(0, hudHolderYCoord, frameWidth, frameHeight / 2))
hudHolder.backgroundColor = UIColor.clearColor()
self.view.addSubview(hudHolder)
let hud = MBProgressHUD.showHUDAddedTo(hudHolder, animated:true)
let label = "Just a sec.."
hud.labelText = label
Whether its scrollview or tableview, you can refer the following link
MBProgressHUD at center added to tableView or scrollView
