如何以编程方式检测iOS设备 [英] How to detect iOS device programmatically

问题描述

我需要知道哪个iOS设备正在运行应用程序（更准确地说我需要知道的是设备armv6或armv7）。 UIUserInterfaceIdiomPad（）无法检查设备是iPhone4S还是iPhone3G。有可能吗？

I need to know which iOS device is currently running app (saying more exactly I need to know is device armv6 or armv7). UIUserInterfaceIdiomPad() could not check is device an iPhone4S or iPhone3G. Is it possible?

推荐答案

下载 https://github.com/erica/uidevice-extension （UIDevice-Hardware类），你可以使用这些：

Download https://github.com/erica/uidevice-extension (UIDevice-Hardware class) and you can use these:

[UIDevice currentDevice] platformType]   // returns UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // returns @"iPhone 4G"

或检查其视网膜

+ (BOOL) isRetina
{
    if([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
        return [[UIScreen mainScreen] scale] == 2.0 ? YES : NO;

    return NO;
}

或查看iOs版本

+ (BOOL) isIOS5
{
    NSString *os5 = @"5.0";
    NSString *currSysVer = [[UIDevice currentDevice] systemVersion];

    //    currSysVer = @"5.0.1";
    if ([currSysVer compare:os5 options:NSNumericSearch] == NSOrderedAscending) //lower than 4
    {
        return NO;
    }
    else if ([currSysVer compare:os5 options:NSNumericSearch] == NSOrderedDescending) //5.0.1 and above
    {        
        return YES;
    }
    else // IOS 5
    {
        return YES;
    }

    return NO;
}
