UIWebView background is set to Clear Color, but it is not transparent
cocoa-touch, ios, iphone, objective-c, uiwebview
Solution
Also set :
[webView setBackgroundColor:[UIColor clearColor]];
[webView setOpaque:NO];
Problem
I'm developing an iOS 4 application using iOS SDK latest version and XCode 4.2. I have a XIB with a `UIWebView` with Alpha = 1.0, Background set to Clear Color and Opaque is not set. On this XIB I setup an image as background with this code: ``` - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"AboutBackground.png"]]; self.view.backgroundColor = background; [background release]; } return self; } ``` The `UIWebView` is showing an static html: ``` <html><head></head><body style=\"margin:0 auto;text-align:center;background-color: transparent; color:white\">...</body></html> ``` On iOS 5 simulator, its background is transparent, but on an iOS 4 device is grey. Any clue?
