LoginResponse *loginResponseObj = [Utililities loadLoginResponseObjectWithKey:LOGIN_RESPONSE_KEY_FOR_USERDEFAULT];
NSMutableDictionary *dataDict = [NSMutableDictionary dictionary];
[dataDict setValue:[NSNumber numberWithFloat:[LocationManager sharedManager].location.coordinate.latitude] forKey:@"lat"];
[dataDict setValue:[NSNumber numberWithFloat:[LocationManager sharedManager].location.coordinate.latitude] forKey:@"lng"];

NSMutableDictionary *timeStampDict = [NSMutableDictionary dictionary];
NSTimeInterval timeInSeconds = [[NSDate date] timeIntervalSince1970];
[timeStampDict setValue:dataDict forKey:[NSString stringWithFormat:@"%.0f",timeInSeconds]];
NSMutableDictionary *fcmDict = [NSMutableDictionary dictionary];
[fcmDict setValue:timeStampDict forKey:loginResponseObj.workerInfo.fcmId];

Answer 1

I had a similar problem and found in the project code, for example:

[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60) forBarMetrics:UIBarMetricsDefault];

I just deleted it.

if(@available(iOS 11, *)) {
   [[UIBarButtonItem appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor clearColor]} forState:UIControlStateNormal];
   [[UIBarButtonItem appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor clearColor]} forState:UIControlStateHighlighted];

} else {
   [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(-60, -60) forBarMetrics:UIBarMetricsDefault];
}
