如今Apple市场上，愈来愈流行刘海屏手机(与Android市场同样，往刘海屏手机方向发展趋势)。windows

在iPhone手机角度上看，刘海屏出如今机型较新的手机上(相对较旧/老的iPhone上还没出现)。ide

那么，如何判断当前的iPhone手机是刘海屏手机呢？同时，如何获取刘海高度？工具

在这里，提供一个工具类：code

NotchScreenUtil.h接口

/*

* iPhone刘海屏工具类

*/

@interface NotchScreenUtil : NSObject

// 判断是不是刘海屏

+(BOOL)isIPhoneNotchScreen;

// 获取刘海屏高度

+(CGFloat)getIPhoneNotchScreenHeight;

@end

NotchScreenUtil.mget

#import

#import "NotchScreenUtil.h"

@implementation NotchScreenUtil

+ (BOOL)isIPhoneNotchScreen{

BOOL result = NO;

if (UIDevice.currentDevice.userInterfaceIdiom != UIUserInterfaceIdiomPhone) {

return result;

}

if (@available(iOS 11.0, *)) {

UIWindow *mainWindow = [[[UIApplication sharedApplication] delegate] window];

if (mainWindow.safeAreaInsets.bottom > 0.0) {

result = YES;

}

}

return result;

}

+ (CGFloat)getIPhoneNotchScreenHeight{

/*

* iPhone8 Plus UIEdgeInsets: {20, 0, 0, 0}

* iPhone8 UIEdgeInsets: {20, 0, 0, 0}

* iPhone XR UIEdgeInsets: {44, 0, 34, 0}

* iPhone XS UIEdgeInsets: {44, 0, 34, 0}

* iPhone XS Max UIEdgeInsets: {44, 0, 34, 0}

*/

CGFloat bottomSpace = 0;

if (@available(iOS 11.0, *)) {

UIEdgeInsets safeAreaInsets = UIApplication.sharedApplication.windows.firstObject.safeAreaInsets;

switch (UIApplication.sharedApplication.statusBarOrientation) {

case UIInterfaceOrientationPortrait:

{

bottomSpace = safeAreaInsets.bottom;

}

break;

case UIInterfaceOrientationLandscapeLeft:

{

bottomSpace = safeAreaInsets.right;

}

break;

case UIInterfaceOrientationLandscapeRight:

{

bottomSpace = safeAreaInsets.left;

}

break;

case UIInterfaceOrientationPortraitUpsideDown:

{

bottomSpace = safeAreaInsets.top;

}

break;

default:

{

bottomSpace = safeAreaInsets.bottom;

}

break;

}

}

return bottomSpace;

}

@end

注：开放接口可用范围在iOS 11以上。it
