Error Message using a custom class (Property type 'view' not found)

I am using a custom class very similar to the Tweet Bot info panels in my application. I have this class working perfectly when a button is tapped, however what I am trying to achieve is getting this 'alert panel' to show when my application finishes launching or comes from being idle.

To call this class using a standard I am using the following code;

-(IBAction) button1Tapped:(id) sender
{
    [MKInfoPanel showPanelInView:self.view 
                            type:MKInfoPanelTypeInfo 
                           title:@"Tweet Posted!" 
                        subtitle:nil 
                       hideAfter:2];
}

But I am having issues including this in my main AppDelegate.m. I keep getting an error message of 'Property type view not found in Total_HealthAppDelegate when i use the following;

- (void)applicationWillEnterForeground:(UIApplication *)application
{

        [MKInfoPanel showPanelInView:self.view
                                type:MKInfoPanelTypeInfo 
                               title:@"Total:Health Support" 
                            subtitle:@"Welcome"
                           hideAfter:3];

}

Any advice would be great

Try using self.window in place of self.view when this code is inside the AppDelegate. Also be sure to include the appropriate header files and declare the class.

However, I recommend you put this code into the viewController that first wakes up instead. Here's one way to accomplish this.

Set up a BOOL in NSUserDefaults called justWokeUp. Then, in the appDelegate, set it to YES when the app wakes up:

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
    [standardUserDefaults setBool:YES forKey:@"justWokeUp];
}

Now, in any viewController that might be the first to load when the app resumes, check this value to see whether you should send the alert:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
    if ([standardUserDefaults boolForKey:@"justWokeUp"]) {

        [MKInfoPanel showPanelInView:self.view
                                type:MKInfoPanelTypeInfo 
                               title:@"Total:Health Support" 
                            subtitle:@"Welcome"
                           hideAfter:3];

        [standardUserDefaults setBool:NO forKey:@"justWokeUp"];


}
