In ViewController class,
.h
#protocol DelegateMethod <NSObject>
-(void)removeArray;
#end
#interface ViewController : UIViewController
#property (nonatomic, strong) id <DelegateMethod> delegate;
#end
.m
-(void)sendInviationAPI:(NSString *)url withParameter:(NSDictionary *)parameters{
// To Check Network Available or Unavailable
if (![PCCommonUtility checkForNetwork]) {
[[PCAlertUtility sharedInstance]showOkAlertWithTitle:[LocalizedStrings warning] description:[LocalizedStrings networkFailure] completion:nil];
}else{
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
// To Check Access token is null or empty
if ([APPDELEGATE.defaults valueForKey:CURRENT_TOKEN] && ![[APPDELEGATE.defaults valueForKey:CURRENT_TOKEN]isKindOfClass:[NSNull class]]) {
[PCAPIUtility getResponseFromAPI:url withParameters:parameters withSuccess:^(NSMutableArray *responseData, NSString *success) {
DLog(#"InviteSuccess:%#",responseData);
NSString *status = [NSString stringWithFormat:#"%#",[responseData valueForKey:#"status"]];
NSString *message = [NSString stringWithFormat:#"%#",[responseData valueForKey:#"message"]]
