8 years ago 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

}

}

}`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.

tabBarController_.tabBarController.selectedViewController.tabBarItem.badgeValue = @"23";But value not changed. Help, please. :)
