[self.banner loadAndShow];

self.banner.loadAndShow()

Notes: The loadAndShow method can be called multiple times at any time, but we do not recommend continuous requests within a short period of time. Making many requests in a short period of time makes no sense because the inventory's availability is unlikely to change much over this period. 

Please do not request Banner ads regularly in the application, OpenMediation SDK will automatically refresh Banner ads regularly.

Step 3. Safe Area Layout Implementation

Safe area refers to the layout guides introduced as part of iOS11, defining the allowed position views in iOS applications. It makes sure that your application will not cover any ancestor views, including navigation and tab bars.

if (@available(iOS 11.0, *)) {
    [_banner setCenter:CGPointMake(self.view.center.x, self.view.frame.size.height - _banner.frame.size.height/2.0 - self.view.safeAreaInsets.bottom)];
 } else {
    [_banner setCenter:CGPointMake(self.view.center.x, self.view.frame.size.height - _banner.frame.size.height/2.0)];
 }

if #available(iOS 11.0, *) {
    banner.center = CGPoint.init(x:self.view.center.x, y:self.view.frame.size.height - banner.frame.size.height/2.0 - self.view.safeAreaInsets.bottom)
 } else {
    banner.center = CGPoint.init(x:self.view.center.x, y:self.view.frame.size.height - banner.frame.size.height/2.0)
 }

Step 4. Integrate a Banner Provider

You can find the supported networks below, and bannerSize behaviour for each network below:
