Multi call for NSURLConnection with multi UITableView in Same Controller - iphone

Question

I have to call two different API in a same view controller and have to show the data on two tableView in same controller, i’m using NSURLConnection for this. but i’m unable to show the result on both of the tableView.
Only urlConnection (for the firstTimeCall) is gave the result . For the secondTimeCall the result is 0.
Can anyone please provide me the samples or able to suggest me the way to do this.
Thanks In Advance.

Answer 1

I assume that the two NSLog in didReceiveData are fine, but it's just that the log in connectionDidFinishLoading for the second connection is wrong? This would be because the second half of your connectionDidFinishLoading, you're looking at responseData, and I assume you meant to look at responseDataTwo. I'd also suggest you update your NSLog statements to clearly state which is #1 and which is #2 (e.g. in didReceiveData, you're just logging, but you don't know which is which (though by looking at the data, I suspect you can make an intelligent guess.).

Answer 2

Call methods [self firstTimeCall];, and [self SecondTimeCall]; in Synchronous ways. by default this time in ur code you are calling methods in async way.
First call [self firstTimeCall]; method and when you received the response and when you have get call in connectionDidFinishLoading delegate method for firstTimeCall, then start calling SecondTimeCall from here.
Overall first call firstTimeCall adn received its data response from server after completing this call, now call SecondTimeCall.
