Show a view over the keyboard

Question

I am looking for a way on the iPhone, due to a custom 'loading' subview, to have a subview cover the keyboard without dismissing the keyboard. Right now when the subview loads, the keyboard is still topmost. Any ideas?

Whenever You are adding subview to the current View just write this code before adding subview [TextView resignFirstResponder]; as you are opening keyboard from UITextView. – Epigraphic

Answer 1

add your loading view as subview on window. It will cover keyboard too. Here is a stackoverflow post for the same

IPhone - Show Wait Indicator

UPDATE

My code

#pragma mark -
#pragma mark Waiting View
- (void)showWaitingView {

    CGRect frame = CGRectMake(90, 190, 32, 32);
    UIActivityIndicatorView* progressInd = [[UIActivityIndicatorView alloc] initWithFrame:frame];
    [progressInd startAnimating];
    progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;

    frame = CGRectMake(130, 193, 140, 30);
    UILabel *waitingLable = [[UILabel alloc] initWithFrame:frame];
    waitingLable.text = @"Processing...";
    waitingLable.textColor = [UIColor whiteColor];
    waitingLable.font = [UIFont systemFontOfSize:20];;
    waitingLable.backgroundColor = [UIColor clearColor];
    frame = [[UIScreen mainScreen] applicationFrame];
    UIView *theView = [[UIView alloc] initWithFrame:frame];
    theView.backgroundColor = [UIColor blackColor];
    theView.alpha = 0.7;
    theView.tag = 999;
    [theView addSubview:progressInd];
    [theView addSubview:waitingLable];

    [progressInd release];
    [waitingLable release];

    [window addSubview:[theView autorelease]];
    [window bringSubviewToFront:theView];
}

- (void)removeWaitingView {
    UIView *v = [window viewWithTag:999];
    if(v) [v removeFromSuperview];

}

Thanks for the link. Actually MBProgressHUD is what I am trying to implement. however, I want the keyboard to always remain visible and MBProgressHUD is behind the keyboard. – Aymara

@Jake Sankey You can add mbprogresshud to window instead of current view.I'm posting a simple code to display a activity indicator. You can use that. – Deva

there is no 'window' in my implementation file. it is in the app delegate. i tried [super.view.window addSubview:HUD]; with no luck ... – Aymara

you have window in applicationDelegate. From app delegate you need to call this function. – Deva

I'm sorry Rahul, I don't understand what you mean. What function am I calling? I am trying to load the MBProgressHUD over my viewcontroller so the appdelegate (which defines 'window') doesn't seem accessible. – Aymara

you can access appDelegate anywhere in the application using the below code yourAppdelegateName *appDelegate = [UIApplication sharedApplication].delegate; By the way the code I have posted you need to paste into your appDelegate class. And then access like this. yourAppdelegateName *appDelegate = [UIApplication sharedApplication].delegate; //To display waiting View [appDelegate showWaitingView]; //To remove Waiting View [appDelegate removeWaitingView]; – Deva

this doesn't seem to work with the iOS5 SDK. The keyboard is on top no matter what. – Chalet

@interface UIApplication (Util)

- (void)addSubViewOnFrontWindow:(UIView *)view;

@end

@implementation UIApplication (Util)

- (void)addSubViewOnFrontWindow:(UIView *)view {
    int count = [self.windows count];
    UIWindow *w = [self.windows objectAtIndex:count - 1];
    [w addSubview:view];
}

@end


UIApplication *app = [UIApplication sharedApplication];
[app addSubViewOnFrontWindow:_loadingView];

Just add the view to [UIApplication sharedApplication].windows.lastObject also work, thanks. – Cesarean

Answer 3

UIWindow *window = [UIApplication sharedApplication].windows.lastObject;
[window addSubview:self.view];                                                                                                                                                                                                                                        
[window bringSubviewToFront:self.view];
