獲得裝置的唯一識別碼UDID，標識符udid

獲得裝置的唯一識別碼UDID，標識符udid

在IOS5之後，蘋果為避免根據UDID獲得使用者的資訊，而禁止使用uniqueIdentifier獲得UDID，但是仍有些應用需要根據UDID區分裝置

有一個系統的庫IOKit.framework可以獲得裝置的唯一標識

    NSString *serialNumber = nil;    NSString * path = [[NSBundle mainBundle]pathForResource:@"IOKit.framework" ofType:nil];    const char * a =[path UTF8String];//    void *IOKit = dlopen(a, RTLD_NOW);    void *IOKit = dlopen("/System/Library/Frameworks/IOKit.framework/IOKit", RTLD_NOW);    if (IOKit)    {        mach_port_t *kIOMasterPortDefault = dlsym(IOKit, "kIOMasterPortDefault");        CFMutableDictionaryRef (*IOServiceMatching)(const char *name) = dlsym(IOKit, "IOServiceMatching");        mach_port_t (*IOServiceGetMatchingService)(mach_port_t masterPort, CFDictionaryRef matching) = dlsym(IOKit, "IOServiceGetMatchingService");        CFTypeRef (*IORegistryEntryCreateCFProperty)(mach_port_t entry, CFStringRef key, CFAllocatorRef allocator, uint32_t options) = dlsym(IOKit, "IORegistryEntryCreateCFProperty");        kern_return_t (*IOObjectRelease)(mach_port_t object) = dlsym(IOKit, "IOObjectRelease");                if (kIOMasterPortDefault && IOServiceGetMatchingService && IORegistryEntryCreateCFProperty && IOObjectRelease)        {            mach_port_t platformExpertDevice = IOServiceGetMatchingService(*kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice"));            if (platformExpertDevice)            {                CFTypeRef platformSerialNumber= IORegistryEntryCreateCFProperty(platformExpertDevice, CFSTR("IOPlatformUUID"), kCFAllocatorDefault, 0);                if (CFGetTypeID(platformSerialNumber) == CFStringGetTypeID())                {                    serialNumber = [NSString stringWithString:(__bridge NSString*)platformSerialNumber];                    CFRelease(platformSerialNumber);                }                IOObjectRelease(platformExpertDevice);            }        }        dlclose(IOKit);    }    return serialNumber;

但是這個方法只能獲得模擬器上的UDID很坑爹啊

那還有另外的方法獲得裝置的資訊，那就是走蘋果的MDM
