iPhone11+适配总结

苹果新增三款新机型iPhone 11，iphone 11 Pro及iPhone 11 Pro Max，其尺寸分别为6.1英寸，5.8英寸以及6.5英寸。
因为iPhone 11与iPhone XR尺寸一致，iPhone 11 Pro和iPhone Xs差不多，iPhone 11 Pro Max尺寸比和iPhone Xs Max也差不多，所以无需刻意适配【屏幕适配。

但需适配的是设备名
由于没有真机实验，但经过分析研究，推测出iPhone 11，iphone 11 Pro及iPhone 11 Pro Max对应内核号分别为"iPhone12,1"，"iPhone12,3"，"iPhone12,5"

//新增宏定义及判断逻辑
#define kDeviceModelIPhone11 @"iPhone12,1"
#define kDeviceModelIPhone11_Pro @"iPhone12,3"
#define kDeviceModelIPhone11_Pro_Max @"iPhone12,5"

     else if ([deviceString isEqualToString:kDeviceModelIPhone11] ) return @"iPhone11";
     else if ([deviceString isEqualToString:kDeviceModelIPhone11_Pro] ) return @"iPhone11 Pro";
     else if ([deviceString isEqualToString:kDeviceModelIPhone11_Pro_Max] ) return @"iPhone11 Pro Max";

以上
