Question

I have 3 methods in which i want that all complete execution one by one.

It probably be done using blocks but i cant learn how to create own blocks. Or Is there any other way to achieve this?

I have scenario as,

Also same scenario without blocks & all is running fine in ios6 but os lower than that is not working

[self getIndex];
[self expandrows]; //I want this expandrows to be called only after everything in getIndex is finished.

-(void)getIndex
    {
     [self didSelectRowAtIndexPath:indexPath];
     //Once this didselect is completed execution than after only i want to start this loop
            for (int index = 0; index < [tableView numberOfRowsInSection:0]; index++)
           {
                NSMutableDictionary *aMutDicCur = [self.model itemForRowAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]];
                if([[aMutDicCur valueForKey:@"CategoryId"] intValue] == 4)
                {
                    indexPath = [NSIndexPath indexPathForRow:index inSection:0];
                    break;
                }
           }

    //After this loop finishes i need to again call one other method
    }

As far as I know blocks are asynchronous.So in that case

Answer 1

Call this [self expandrows]; after when you finish your second method call which is call in

get index method.
