获取设备ID在IOS

Question

运行视图控制器代码之前，我有这个代码的和平得到设备ID：

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{ 
    NSString *devicetokenRN = [NSString stringWithFormat:@"%@", deviceToken]; 
    devicetokenRN = [devicetokenRN stringByReplacingOccurrencesOfString:@" " withString:@""]; 
    devicetokenRN = [devicetokenRN stringByReplacingOccurrencesOfString:@"<" withString:@""]; 
    devicetokenRN = [devicetokenRN stringByReplacingOccurrencesOfString:@">" withString:@""]; 


    // send device token for APNS without spaces or <> 
    DeviceID *DeviceIdentifier = [[DeviceID alloc ] init]; 
    // sending it to the Device.h 
    [DeviceIdentifier setDeviceID:devicetokenRN]; 
} 

我需要检索此的DeviceID作为我的ViewController的第一件事。由于它运行的视图控制器之前，因为如果我在ViewController中使用的NSLog它是NULL，因为它并没有执行这个第一它没有做这个功能。在运行UITableView之前，我需要先获得一些像这样的变量。任何想法将是非常感谢。

Answer 1

在AppDelegate中获得整个项目的任何地方，你可以保存在NSUserDefaults的的deviceToken值像

把这些线didRegisterForRemoteNotificationsWithDeviceToken方法在这样

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 

{ 

    [[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"DeviceToken"]; 
    [[NSUserDefaults standardUserDefaults] synchronize]; 

} 

ppdelegate.m也把下面这行代码在你看来Controller.m或者在viewDidLoad方法

和检索值。

[[NSUserDefaults standardUserDefaults] objectForKey:@"DeviceToken"];

您可以获取和存储您的DEVICEID在NSUserDefaults

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 
{ 
    NSUUID *identifierForVendor = [[UIDevice currentDevice] identifierForVendor]; 
    NSString *deviceId = [identifierForVendor UUIDString]; 
    NSUserDefaults *userRegistrarionDetails = [NSUserDefaults standardUserDefaults]; 
    [userRegistrarionDetails setObject:deviceId forKey:@"deviceID"]; 
    [userRegistrarionDetails synchronize]; 
} 

，您可以通过

NSUserDefaults *userRegistrarionDetails = [NSUserDefaults standardUserDefaults]; 
NSString * deviceId = [userRegistrarionDetails objectForKey:@"deviceID"]; 
NSLog(@"%@", deviceId);
