loading screen not centered on second launch - objective-c

Question

I have a UIView which is my loading view. All it does is display the circular loading circle(lol to much "circle" for one sentence).
It works fine the first time but after that the circle is not centered. It moves to the left and down some. How can I get it to always be centered, take in mind I have limited the app to only display in the landscape modes (landscape left, landscape right) in all views so the issue is not coming from the device being rotated.
call to load the view:
loadingViewController = [LoadingViewController loadSpinnerIntoView:self.view];
LoadingViewController.h:
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import "CrestronClient.h"
#interface LoadingViewController : UIView
{
CrestronClient *cClient;
}
+(LoadingViewController *)loadSpinnerIntoView:(UIView *)superView;
-(void)removeLoadingView;
- (UIImage *)addBackground;
#end
LoadingView.m:
#import "LoadingViewController.h"
#import "RootViewController.h"
#implementation LoadingViewController
CGRect priorFrameSettings;
UIView *parentView;
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||interfaceOrientation == UIInterfaceOrientationLandscapeRight ) {
return YES;
}else{
return NO;
}
}
-(void)removeLoadingView
{
// [parentView setFrame:priorFrameSettings];
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionFade];
[[[self superview] layer] addAnimation:animation forKey:#"layerAnimation"];
[self removeFromSuperview];
}
+(LoadingViewController *)loadSpinnerIntoView:(UIView *)superView
{
priorFrameSettings = superView.frame;
parentView = superView;
// [superView setFrame:CGRectMake(0, 0, 1024, 1024)];
// Create a new view with the same frame size as the superView
LoadingViewController *loadingViewController = [[LoadingViewController alloc] initWithFrame:superView.frame];
loadingViewController.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
// If something's gone wrong, abort!
if(!loadingViewController){ return nil; }
[superView addSubview:loadingViewController];
if(!loadingViewController){ return nil; }
// This is the new stuff here ;)
UIActivityIndicatorView *indicator =
[[[UIActivityIndicatorView alloc]
initWithActivityIndicatorStyle: UIActivityIndicatorViewStyleWhiteLarge] autorelease];
// Set the resizing mask so it's not stretched
UIImageView *background = [[UIImageView alloc] initWithImage:[loadingViewController addBackground]];
// Make a little bit of the superView show through
background.alpha = 0.7;
[loadingViewController addSubview:background];
indicator.autoresizingMask =
UIViewAutoresizingFlexibleTopMargin |
UIViewAutoresizingFlexibleRightMargin |
UIViewAutoresizingFlexibleBottomMargin |
UIViewAutoresizingFlexibleLeftMargin;
// Place it in the middle of the view
indicator.center = superView.center;
// Add it into the spinnerView
[loadingViewController addSubview:indicator];
// Start it spinning! Don't miss this step
[indicator startAnimating];
// Create a new animation
CATransition *animation = [CATransition animation];
// Set the type to a nice wee fade
[animation setType:kCATransitionFade];
// Add it to the superView
[[superView layer] addAnimation:animation forKey:#"layerAnimation"];
return loadingViewController;
}
- (UIImage *)addBackground{
cClient = [CrestronClient sharedManager];
if (cClient.isConnected == FALSE) {
[cClient connect];
}
// Create an image context (think of this as a canvas for our masterpiece) the same size as the view
UIGraphicsBeginImageContextWithOptions(self.bounds.size, YES, 1);
// Our gradient only has two locations - start and finish. More complex gradients might have more colours
size_t num_locations = 2;
// The location of the colors is at the start and end
CGFloat locations[2] = { 0.0, 1.0 };
// These are the colors! That's two RBGA values
CGFloat components[8] = {
0.4,0.4,0.4, 0.8,
0.1,0.1,0.1, 0.5 };
// Create a color space
CGColorSpaceRef myColorspace = CGColorSpaceCreateDeviceRGB();
// Create a gradient with the values we've set up
CGGradientRef myGradient = CGGradientCreateWithColorComponents (myColorspace, components, locations, num_locations);
// Set the radius to a nice size, 80% of the width. You can adjust this
float myRadius = (self.bounds.size.width*.8)/2;
// Now we draw the gradient into the context. Think painting onto the canvas
CGContextDrawRadialGradient (UIGraphicsGetCurrentContext(), myGradient, self.center, 0, self.center, myRadius, kCGGradientDrawsAfterEndLocation);
// Rip the 'canvas' into a UIImage object
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
// And release memory
CGColorSpaceRelease(myColorspace);
CGGradientRelease(myGradient);
UIGraphicsEndImageContext();
// … obvious.
return image;
}
- (void)dealloc {
[super dealloc];
}
#end

Answer 1

Make sure the loading view is set to its parents frame and has the proper autoresizingMask set. This would likely by UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight.

Answer 2

fixed the background by adding
[background setFrame:CGRectMake(0, 0, 1024, 768 )];
and fixed the centering of the circle with:
indicator.center = background.center;
