How to make status bar translucent? - objective-c

Question

i need help in making status bar translucent. In some parts of app its working fine, and in other its not.
This is how status bar is coming if i show navugation bar.
this is how is showing when i remove the navigation bar.
I need to show the navigation bar but status bar should be translucent. The background image is pushed down with the navigation bar.I have set the background image programmatically making a base class.
-(void)addBackGroundImage{
self.backGroundImage=[[UIImageView alloc] init];
self.backGroundImage.translatesAutoresizingMaskIntoConstraints=NO;
[self.backGroundImage setImage:[UIImage imageNamed:#"background"]];
self.backGroundImage.contentMode=UIViewContentModeScaleAspectFill;
[self.view addSubview:self.backGroundImage];
[self.view sendSubviewToBack:self.backGroundImage];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"|[_backGroundImage]|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(_backGroundImage)]];
[self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:#"V:|-(0)-[_backGroundImage]|" options:0 metrics:nil views:NSDictionaryOfVariableBindings(_backGroundImage)]];
AppDelegate *objAppDelegate=[[UIApplication sharedApplication] delegate];
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, 20)];
view.backgroundColor=[UIColor clearColor];
[view setAlpha:0.2];
}
-(void)updateBackgroundImage:(UIImage *)bgImage{
[self.backGroundImage setImage:bgImage];
}

It is actually what you need to completely remove default header background (statusBar + navigationBar) and set your own:
// ViewController.m
self.navigationController.navigationBar.backgroundColor = [UIColor clearColor];
self.navigationController.navigationBar.tintColor = [UIColor yourColor]; // Set your tint color
self.navigationController.navigationBar.shadowImage = [UIImage new];
self.navigationController.navigationBar.translucent = YES;
self.navigationController.navigationBar.opaque = NO;
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
UIView *bgView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 64)];
bgView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"Your_Background_Image"]];
[self.view addSubview:bgView];
