问题
I got the device token through didRegisterForRemoteNotificationsWithDeviceToken method. I wanted to use the device token in another method. I tried it in this way,
In didRegisterForRemoteNotificationsWithDeviceToken method:
str = [NSString stringWithFormat:@"%@",deviceToken];
// str is the NSString which is declared in the appDelegate.h file as global variable
In didReceiveRemoteNotification method:
NSLog(@"Device Token : %@",str);
When i do like this the Device Token is returning as "nosniff".
How can i store this device token in a global variable and use it in the other class or in other method.
回答1:
In your app delegate class define method + (CustomAppDelegate *)sharedAppDelegate whose implementation should look like this one:
+ (CustomAppDelegate *)sharedAppDelegate
{
return (CustomAppDelegate *) [UIApplication sharedApplication].delegate;
}
where CustomAppDelegate is name of your app delegate class.
In method your need to get value of str variable you should type following:
NSString *token = [[CustomAppDelegate sharedAppDelegate] str];
where CustomAppDelegate is name of your app delegate class and str is synthesized property (or name of the method) where device token is stored.
Before calling sharedAppDelegate don't forget to import "CustomAppDelegate.h"

You can add the device token to the NSUserDefaults dictionary like so:
-(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
[[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"deviceToken"];
This can then be accessed in other methods like so:
NSString *deviceToken = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceToken"];
