通过Java使用Apple Push Notification Service

通过Java使用Apple Push Notification Service

一点提示，为了将收到的令牌转换为适合用javapns注册的格式，此代码可以解决问题：

- (NSString *)convertTokenToDeviceID:(NSData *)token {NSMutableString *deviceID = [NSMutableString string];// iterate through the bytes and convert to hexunsigned char *ptr = (unsigned char *)[token bytes];for (NSInteger i=0; i < 32; ++i) {    [deviceID appendString:[NSString stringWithFormat:@"%02x", ptr[i]]];}return deviceID;

}
