这篇文章将为大家详细讲解有关iOS如何适配iPhone X,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
因为iPhone X奇特的刘海存在,iOS11之后系统深化了“安全区域”概念,安全区域就是从屏幕上切除最大的矩形之外的区域。
iOS11后UIScrollView新增contentInsetAdjustmentBehavior属性,默认配置UIScrollViewContentInsetAdjustmentAutomatic,效果上就是没使用安全区域。若针对具体页面需要使用安全区域,可以查看API中新增加的那些属性。
/**
* 适配iPhone X的安全区域
* isUse = 1 表示使用安全区域
* isUse = 0 表示不使用安全区域
*/
+ (void)adaptationSafeAreaWith:(UIScrollView *)sv useArea:(NSInteger)isUse {
if ([[sv class] isSubclassOfClass:[UIWebView class]]) {
UIWebView *webView = (UIWebView *)sv;
for (UIView *aView in [webView subviews]) {
if ([aView isKindOfClass:[UIScrollView class]]) {
sv = (UIScrollView *)aView;
break;
}
}
}
#ifdef __IPHONE_11_0
if ([sv respondsToSelector:@selector(setContentInsetAdjustmentBehavior:)]) {
if (isUse) {
if (@available(iOS 11.0, *)) {
sv.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
if ([[sv class] isSubclassOfClass:[UITableView class]]) {
UITableView *tv = (UITableView *)sv;
[tv setInsetsContentViewsToSafeArea:NO];
}
} else {
// Fallback on earlier versions
}
} else {
if (@available(iOS 11.0, *)) {
sv.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentAlways;
} else {
// Fallback on earlier versions
}
}
}
#endif
}
typedef NS_ENUM(NSInteger, UIScrollViewContentInsetAdjustmentBehavior) {
UIScrollViewContentInsetAdjustmentAutomatic, // Similar to .scrollableAxes, but for backward compatibility will also adjust the top & bottom contentInset when the scroll view is owned by a view controller with automaticallyAdjustsScrollViewInsets = YES inside a navigation controller, regardless of whether the scroll view is scrollable
UIScrollViewContentInsetAdjustmentScrollableAxes, // Edges for scrollable axes are adjusted (i.e., contentSize.width/height > frame.size.width/height or alwaysBounceHorizontal/Vertical = YES)
UIScrollViewContentInsetAdjustmentNever, // contentInset is not adjusted
UIScrollViewContentInsetAdjustmentAlways, // contentInset is always adjusted by the scroll view's safeAreaInsets
} API_AVAILABLE(ios(11.0),tvos(11.0));
