IOS获取物理尺寸中7Plus中获取的是7的物理尺寸

IOS获取物理尺寸中7Plus中获取的是7的物理尺寸：

在开发调试过程中我的7Plus手机获取[uiscreen mainscreen].bounds为750  、1334.

解决方案：在手机中的显示与亮度更改为标准，就可以解决办法。一般情况下都是以物理尺寸来判断手机的启动页和广告的。毕竟如果用

+ (NSString *)iphoneType {

    

    

    struct utsname systemInfo;

    

    uname(&systemInfo);

    

    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

    

    if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";

    

    if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";

    

    if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";

    

    if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";

    

    if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4";

    

    if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4";

    

    if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";

    

    if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";

    

    if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5";

    

    if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c";

    

    if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c";

    

    if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s";

    

    if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s";

    

    if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";

    

    if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6";

    

    if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";

    

    if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";

    

    if ([platform isEqualToString:@"iPhone8,4"]) return @"iPhone SE";

    

    if ([platform isEqualToString:@"iPhone9,1"]) return @"iPhone 7";

    

    if ([platform isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus";

    

    if ([platform isEqualToString:@"i386"]) return @"iPhone Simulator";

    

    if ([platform isEqualToString:@"x86_64"]) return @"iPhone Simulator";

    

    return platform;

    

}

 增加手机就要判断。判断会很多、累赘
