ios开发 各机型屏幕适配

一、像素大小

新增4款手机3种分辨率，直接上图：

二、机型判断的宏定义

更新下宏定义，又可以愉快的写bug了。

// 判断 iPad

#define DX_UI_IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

// 判断iPhone X

#define DX_Is_iPhoneX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) : NO)

//判断iPHoneXr | 11

#define DX_Is_iPhoneXR ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//判断iPHoneXs | 11Pro

#define DX_Is_iPhoneXS ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//判断iPhoneXs Max | 11ProMax

#define DX_Is_iPhoneXS_MAX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//判断iPhone12_Mini

#define DX_Is_iPhone12_Mini ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1080, 2340), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//判断iPhone12 | 12Pro

#define DX_Is_iPhone12 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1170, 2532), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//判断iPhone12 Pro Max

#define DX_Is_iPhone12_ProMax ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1284, 2778), [[UIScreen mainScreen] currentMode].size) && !DX_UI_IS_IPAD : NO)

//x系列

#define DX_IS_IPhoneX_All (DX_Is_iPhoneX || DX_Is_iPhoneXR || DX_Is_iPhoneXS || DX_Is_iPhoneXS_MAX || DX_Is_iPhone12_Mini || DX_Is_iPhone12 || DX_Is_iPhone12_ProMax)
