How to change tabBarItem.badgeValue ?

[LunevNF]

How can I change a badge value of tabItem?
I was try:
tabBarController_.tabBarController.selectedViewController.tabBarItem.badgeValue = @"23";
But value not changed. Help, please. :)

Ohh, ESTabBarController returns nil of tabBarController. That's why I was change Pod project of ESTabBarController and add some code.
I think, that a lot of people can't find a normal way for this issue. This code from my project may help you:

Because of we get PUSH-info in appDelegate.h, we must create some variables here. This varibles are contains count numbers for 4 tabs. Paste from my AppDelegate.m:

`//
//  AppDelegate.m
//
#import "ESTabBarController.h"

@interface AppDelegate ()
@end

NSString *tabBadge0, *tabBadge1, *tabBadge2, *tabBadge3, *tabBadge4;
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//some code...

//Получение версии ОС
NSString *ver = [[UIDevice currentDevice] systemVersion];
//int ver_int = [ver intValue];
float ver_float = [ver floatValue];

//Register PUSH-permissions
if (ver_float < 8.0){
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

if (ver_float >= 8.0){
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}

//Try get PUSH-info (when app opened after app's full shutdown)
NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

if (userInfo) {
    //example of getting numbers from PUSH for tabs
    NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

    NSArray *notice = [userInfo objectForKey:@"notices"];
    NSDictionary *questAnswer_ = [notice objectAtIndex:0];
    NSDictionary *news_ = [notice objectAtIndex:1];
    NSDictionary *npa_ = [notice objectAtIndex:2];
    NSDictionary *msgsAnswer = [notice objectAtIndex:3];                

    //And now we save those numbers to our String variables was implemented before
    tabBadge1 = [NSString stringWithFormat:@"%d",[[questAnswer_ objectForKey:@"count"] integerValue]];
    tabBadge2 = [NSString stringWithFormat:@"%d",[[news_ objectForKey:@"count"] integerValue]];
    tabBadge3 = [NSString stringWithFormat:@"%d",[[npa_ objectForKey:@"count"] integerValue]];
    tabBadge4 = [NSString stringWithFormat:@"%d",[[msgsAnswer objectForKey:@"count"] integerValue]];

    //copy values from appDelegate to ESTabBarController
    tabBarController_.tabBadge1 = tabBadge1;
    tabBarController_.tabBadge2 = tabBadge2;
    tabBarController_.tabBadge3 = tabBadge3;
    tabBarController_.tabBadge4 = tabBadge4;

    //Change main Badge for App Icon in main IPhone menu
    NSInteger badgeSum = [[questAnswer_ objectForKey:@"count"] integerValue]
    + [[news_ objectForKey:@"count"] integerValue]
    + [[npa_ objectForKey:@"count"] integerValue]
    + [[msgsAnswer objectForKey:@"count"] integerValue];
    [UIApplication sharedApplication].applicationIconBadgeNumber = badgeSum;
}

//Register you device Token for PUSH
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken  {

For creating of badges on UIView I used this POD: https://github.com/JaviSoto/JSBadgeView
because this tabBarController not set badge even this metod:
AppDelegate *appD = [AppDelegate sharedAppDelegate]; appD.tabBarController_.tabBarController.selectedViewController.tabBarItem.badgeValue = @"23";
That's all. Hope this help you and sorry for my Russian English. :)
Remember: you must init tabBarController_ and send class-value to AppDelegate.

Hi, @lukitnev! Yeah, ESTabBarController still doesn't support badges in its latest version, nor in its master branch.

However, there's a fork waiting to be merged in #7, that has support for badges. It still has some fixes to do in the code before merging it, but you can use the fork if it fits your needs.

I'll close this issue as it's covered in #7.

Thanks for answer. Yes, can close. :)
