IOS擷取實體尺寸中7Plus中擷取的是7的實體尺寸

IOS擷取實體尺寸中7Plus中擷取的是7的實體尺寸：

在開發調試過程中我的7Plus手機擷取[uiscreen mainscreen].bounds為750  、1334.

解決方案：在手機中的顯示與亮度更改為标準，就可以解決辦法。一般情況下都是以實體尺寸來判斷手機的啟動頁和廣告的。畢竟如果用

+ (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;

}

 增加手機就要判斷。判斷會很多、累贅
