Banner Cerdas adalah unit iklan yang merender iklan banner lebar layar pada semua ukuran layar di berbagai perangkat pada salah satu orientasi. Banner Cerdas mendeteksi lebar perangkat dalam orientasi saat ini dan membuat tampilan iklan dalam ukuran tersebut.
Smart Banner di iPhone memiliki tinggi 50 poin dalam mode potret dan 32 titik dalam lanskap. Pada iPad, tinggi adalah 90 poin dalam mode potret dan lanskap.
Jika iklan gambar tidak cukup besar untuk mengisi seluruh ruang yang dialokasikan, gambar akan dipusatkan dan ruang di kedua sisi akan diisi.
Untuk menggunakan Banner Cerdas, cukup tentukan kGADAdSizeSmartBannerPortrait
(untuk orientasi portait) atau kGADAdSizeSmartBannerLandscape (untuk orientasi
lanskap) untuk ukuran iklan:
Swift
let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
Objective-C
GADBannerView *bannerView = [[GADBannerView alloc]
initWithAdSize:kGADAdSizeSmartBannerPortrait];
Karena penambahan area aman untuk iOS 11, untuk banner dengan lebar penuh, Anda juga harus menambahkan batasan untuk tepi banner ke tepi area aman. Berikut adalah cuplikan kode yang menunjukkan cara melakukannya:
Swift
func addBannerViewToView(_ bannerView: GADBannerView) {
bannerView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(bannerView)
if #available(iOS 11.0, *) {
// In iOS 11, we need to constrain the view to the safe area.
positionBannerViewFullWidthAtBottomOfSafeArea(bannerView)
}
else {
// In lower iOS versions, safe area is not available so we use
// bottom layout guide and view edges.
positionBannerViewFullWidthAtBottomOfView(bannerView)
}
}
// MARK: - view positioning
@available (iOS 11, *)
func positionBannerViewFullWidthAtBottomOfSafeArea(_ bannerView: UIView) {
// Position the banner. Stick it to the bottom of the Safe Area.
// Make it constrained to the edges of the safe area.
let guide = view.safeAreaLayoutGuide
NSLayoutConstraint.activate([
guide.leftAnchor.constraint(equalTo: bannerView.leftAnchor),
guide.rightAnchor.constraint(equalTo: bannerView.rightAnchor),
guide.bottomAnchor.constraint(equalTo: bannerView.bottomAnchor)
])
}
func positionBannerViewFullWidthAtBottomOfView(_ bannerView: UIView) {
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .leading,
relatedBy: .equal,
toItem: view,
attribute: .leading,
multiplier: 1,
constant: 0))
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .trailing,
relatedBy: .equal,
toItem: view,
attribute: .trailing,
multiplier: 1,
constant: 0))
view.addConstraint(NSLayoutConstraint(item: bannerView,
attribute: .bottom,
relatedBy: .equal,
toItem: bottomLayoutGuide,
attribute: .top,
multiplier: 1,
constant: 0))
}
Objective-C
- (void)addBannerViewToView:(UIView *)bannerView {
bannerView.translatesAutoresizingMaskIntoConstraints = NO;
[self.view addSubview:bannerView];
if (@available(ios 11.0, *)) {
// In iOS 11, we need to constrain the view to the safe area.
[self positionBannerViewFullWidthAtBottomOfSafeArea:bannerView];
} else {

[self positionBannerViewFullWidthAtBottomOfView:bannerView];
}
