Loading View with Grayed View...

For Global Display the LoadingView we use some control and we declare this view with our custom Method.And also we declare these method in AppDelegate so we can use this loading view Globally.

-First We Declare Control in AppDelegate.h file

@interface AppDelegate : UIResponder <UIApplicationDelegate>{

           UIView *activityView;

           UIView *loadingView;

           UILabel *lblLoad;

}

-(void) showLoadingView;

-(void) showLoadingViewForWebView;

-(void) hideLoadingView;

After that Just put bellow code in AppDelegate.m file

#pragma mark - Loading View

-(void) showLoadingView {

//NSLog(@"show loading view called");

if (loadingView == nil) {

        

        loadingView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 60.0, 320.0, 420.0)];

        loadingView.opaque = NO;

        loadingView.backgroundColor = [UIColor darkGrayColor];

        loadingView.alpha = 0.5;

UIView *subloadview=[[UIView alloc] initWithFrame:CGRectMake(84.0, 190.0,150.0 ,50.0)];

        subloadview.backgroundColor=[UIColor blackColor];

subloadview.opaque=NO;

subloadview.alpha=0.8;

subloadview.layer.masksToBounds = YES;

subloadview.layer.cornerRadius = 6.0;

lblLoad=[[UILabel alloc]initWithFrame:CGRectMake(50.0, 7.0,80.0, 33.0)];

lblLoad.text=@"LoadingView";

lblLoad.backgroundColor=[UIColor clearColor];

lblLoad.textColor=[UIColor whiteColor];

[subloadview addSubview:lblLoad];

        UIActivityIndicatorView *spinningWheel = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(10.0, 11.0, 25.0, 25.0)];

        [spinningWheel startAnimating];

        spinningWheel.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;

        [subloadview addSubview:spinningWheel];

[loadingView addSubview:subloadview];

        [spinningWheel release];

    }       

    [self.window addSubview:loadingView];

//[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert];

}

-(void) showLoadingViewForWebView {

//NSLog(@"show loading view called");

if (loadingView == nil) {

        loadingView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)];

        loadingView.opaque = NO;

        loadingView.backgroundColor = [UIColor darkGrayColor];

        loadingView.alpha = 0.5;

UIView *subloadview=[[UIView alloc] initWithFrame:CGRectMake(84.0, 175.0,150.0 ,50.0)];

        subloadview.backgroundColor=[ UIColor blackColor];

subloadview.opaque=NO;

subloadview.alpha=0.8;

subloadview.layer.masksToBounds = YES;

subloadview.layer.cornerRadius = 6.0;

lblLoad=[[UILabel alloc]initWithFrame:CGRectMake(50.0, 7.0,80.0, 33.0)];

lblLoad.text=@"LoadingView";

lblLoad.backgroundColor=[UIColor clearColor];

lblLoad.textColor=[UIColor whiteColor];

[subloadview addSubview:lblLoad];

        UIActivityIndicatorView *spinningWheel = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(10.0, 11.0, 25.0, 25.0)];

        [spinningWheel startAnimating];

        spinningWheel.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;

        [subloadview addSubview:spinningWheel];

[loadingView addSubview:subloadview];

        [spinningWheel release];

    }       

    [self.window addSubview:loadingView];

//[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert];

}

-(void) hideLoadingView {

if (loadingView) {

        [loadingView removeFromSuperview];

        [loadingView release];

        loadingView = nil;

    }
