iOS 判断机型是否为 iPhone X、XR、XS、XS Max 的方法

    if ([deviceString isEqualToString:@"iPhone10,1"])   return @"国行(A1863)、日行(A1906)iPhone 8";
    if ([deviceString isEqualToString:@"iPhone10,4"])   return @"美版(Global/A1905)iPhone 8";
    if ([deviceString isEqualToString:@"iPhone10,2"])   return @"国行(A1864)、日行(A1898)iPhone 8 Plus";
    if ([deviceString isEqualToString:@"iPhone10,5"])   return @"美版(Global/A1897)iPhone 8 Plus";
    if ([deviceString isEqualToString:@"iPhone10,3"])   return @"国行(A1865)、日行(A1902)iPhone X";
    if ([deviceString isEqualToString:@"iPhone10,6"])   return @"美版(Global/A1901)iPhone X";

    if ([deviceString isEqualToString:@"iPhone11,2"])   return @"iPhone XS";
    if ([deviceString isEqualToString:@"iPhone11,4"])   return @"iPhone XS Max";

代码中判断是否是iPhone X时需要注意
如果你以前是使用设备尺寸来判断iPhone X那就需要修改了，判断iPhone X主要是因为刘海的原因可能要做些特殊处理。鉴于iPhone X/XS/XR/XS Max底部都会有安全距离，所以可以利用safeAreaInsets.bottom > 0.0来判断是否是iPhone X/XS/XR/XS Max。

safeAreaInsets支持iOS11及以后。

#define IPHONE_X (@available(iOS 11.0, *)?[[[UIApplication sharedApplication] delegate] window].safeAreaInsets.bottom > 0.0:NO )
