The navigation bar stops being translucent when self.edgesForExtendedLayout = UIRectEdgeNone

Question

- (void)viewDidLoad { [super viewDidLoad]; if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) { self.edgesForExtendedLayout = UIRectEdgeNone; self.navigationController.navigationBar.translucent=YES; } // Do any additional setup after loading the view. } 

I do not want my scrollView to be behind the default navigation bar. So I set self.edgesForExtendedLayout = UIRectEdgeNone ;.

This viewDidLoad is the mother viewDidLoad of my entire viewController.

It's good. But I like the translucent effect.

It seems that the translucent effect disappears when I set self.edgesForExtendedLayout to equal.

How to set the value to "none" and get the effect of translucency.

I think a good solution would be to organize a scroll attachment.

I did it

 - (void)viewDidLoad { [super viewDidLoad]; if ([self respondsToSelector:@selector(edgesForExtendedLayout)]) { //self.edgesForExtendedLayout = UIRectEdgeNone; self.navigationController.navigationBar.translucent=YES; self.automaticallyAdjustsScrollViewInsets = YES; } // Do any additional setup after loading the view. } 

And here is what I got:

Answer 1

Transparent means that the content under the panel can be seen through transparency. By turning off the extended edges, transparency still exists, you just don’t see it because there is no content below.

Answer 2

I have the same problem right now. Therefore, if you need to save a translucent navigation bar, you should change the edges, not the edges. Here is the code that helps me.

 if(floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) { CGRect statusBarViewRect = [[UIApplication sharedApplication] statusBarFrame]; float heightPadding = statusBarViewRect.size.height+self.navigationController.navigationBar.frame.size.height; myContentView.contentInset = UIEdgeInsetsMake(heightPadding, 0.0, 0.0, 0.0); } 

Hope this helps.
