Question

I have tried a lot to make UINavigationBar transparent. But I failed making it so.The image which I set was transparent. Here is my code . Any help ? Thanks in advance.

Answer 1

Thanks all. The thing is that I am adding this line in my view controller:

if (IS_OS_7_OR_LATER)
{
    self.edgesForExtendedLayout = UIRectEdgeNone;
    self.extendedLayoutIncludesOpaqueBars = NO;
    self.automaticallyAdjustsScrollViewInsets = NO;
}

that is why the code is not working. When I remove the line

self.edgesForExtendedLayout = UIRectEdgeNone;

the code works.
