如何找到像GSM和CDMA網絡功能

Question

我有一個需要像我需要找到編程方式，具有GSM，CDMA和SPI網絡功能或不具有相關IOS設備。

所以，如果有什麼方法可以找到，請告訴我。

在此先感謝。

使用類，您可以確定您的應用程序是在iPod還是iPhone上運行。要獲取此信息，請訪問名爲model的屬性，該屬性將返回iPhone或iPod touch的NSString。但是，有時您需要更多細節，例如iPhone是最新設備，3GS還是另一端，iPod是第一代還是第二代設備？

訪問系統硬件將顯示我們需要做出上述區別的信息。我們將使用一個類別來擴展UIDevice類，方法是將「機器」類型作爲字符串返回。

@interface UIDevice(machine) 
- (NSString *)machine; 
@end 

訪問硬件類型，我們會打電話給在標準C庫中的函數：

sysctlbyname(const char *name, void *oldp, size_t *oldlenp, void *newp, size_t newlen);

或者

與下面的接口定義開始進口#import <sys/utsname.h>

然後，NSString *deviceName = [Classname myDeviceModel];

+ (NSString*)myDeviceModel 
    { 
    struct utsname deviceInfo; 

    uname(&deviceInfo); 

    NSString *deviceNameTemp = [NSString stringWithCString:deviceInfo.machine encoding:NSUTF8StringEncoding]; 
    NSDictionary *deviceDictionary = 
    @{
