Accessing root view from subclass/subview

[nibby]

Hi all

I have this class called ballImage which is an UIImageView. I instantiate it from my main viewcontroller (myFirstGameViewController) like this:

ballImage *ball = [[ballImage alloc] initWithImage:[UIImage imageNamed:@"Ball.png"]];
ball.center = CGPointMake(100,100);
[ball setUserInteractionEnabled:YES];
[self.view addSubview:ball];

Below is my class where i'd like to animate the ball when it is touched. I can't use self.view since i am now in a subview so how do i access the "main view"? (see the "Error"-line)

#import "ballImage.h"
#import "myFirstGameViewController.h"

@implementation ballImage

- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event {
	NSArray * imageArray  = [[NSArray alloc] initWithObjects:
		[UIImage imageNamed:@"Ball.png"],
		[UIImage imageNamed:@"Ball2.png"],
		[UIImage imageNamed:@"Ball3.png"],
		nil];
	UIImageView * jump = [[UIImageView alloc] initWithFrame:CGRectMake(100, 100, 116, 116)];
	jump.animationImages = imageArray;
	jump.animationDuration = 1.1;
	jump.contentMode = UIViewContentModeBottomLeft;
	[self.myFirstGameViewController.view addSubview:jump]; // <--Error!
	[jump startAnimating];
}

BTW i don't want to move or shrink the ball i want it to puncture so i have made a few images to do this.

Thanks in advance.

Try the superview property

Hi, I am trying to do a similar type of thing.

I have an NSObject but can't seem to access the root view controller. Below is where the error is happening.

UIButton *btnTile = [[UIButton alloc] initWithFrame:CGRectMake(intTempTileX, intTempTileY, intTileWidth, intTileHeight)];
        NSString *strTitle = [NSString stringWithFormat:@"%@", [arrTiles objectAtIndex:i]];
        [btnTile setTitle:strTitle forState:UIControlStateNormal];
        [btnTile addTarget:self action:@selector(dragBegan:withEvent:currentView) forControlEvents: UIControlEventTouchDown];
        [btnTile addTarget:self action:@selector(dragMoved:withEvent:) forControlEvents: UIControlEventTouchDragInside];
        [btnTile addTarget:self action:@selector(dragEnded:withEvent:) forControlEvents: UIControlEventTouchUpInside | UIControlEventTouchUpOutside];
        [btnTile setBackgroundColor:[UIColor blueColor]];
        [RootViewController addSubview:btnTile]; <-- This is where the error is happening
        [btnTile release];
