I am trying to change the background color of a UIWindow when an action is sent to the class MyController. However the UIWindow resides in the AppDelegate class so I don't have access to the variable to modify it using
window.backgroundColor = [UIColor theColor];
in MyController. Here is the code for MyController.m:
@implementation MyController - (IBAction)sliderChanged:(id)sender { //want to call some method to change the UIWindow background color } @end
And here is the code for AppDelegate.h:
@interface AppDelegate : NSObject { UIWindow *window; } - (void)changeColorToRed:(int)r Green:(int)g Blue:(int)b; @property (nonatomic, retain) IBOutlet UIWindow *window; @end
I tried to implement a method changeColorToRed... in the AppDelegate class because that method has access to the variable window
, but I had no way to call that from the sliderChanged
method in MyController.
How can I modify the UIWindow * window from another class?
