Getting JSON data and populate TableView in iOS - ios

Question

Good evening!
I need some help. I'm getting some data from the Google Places API in JSON format but I'm not getting to populate a TableView in iPad (SplitView Based Application). I starting with iOS developing so probably there are many mistakes! I used a project example that used Twitter API to retrieve the posts and just renamed the JSON data names.
I have four files that are used in the project and implement the function:
SimpleSplitController.h
SimpleSplitController.m
SplitSampleAppDelegate.h
SplitSampleAppDelegate.m
I get an ERROR at SplitSampleDelegate.m file, as it's checked there...
If someone may help me, I'd be very grateful!
Here are the codes that implement:
SplitSampleAppDelegate.h
#import <UIKit/UIKit.h>
#class APTabBarControllerForSplitController;
#interface SplitSampleAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
NSMutableData *responseData;
NSMutableArray *tweets;
}
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet APTabBarControllerForSplitController *tabBarController;
#property (nonatomic, retain) NSMutableArray *tweets;
#end
SplitSampleAppDelegate.m
#import "SplitSampleAppDelegate.h"
#import "APTabBarControllerForSplitController.h"
#implementation SplitSampleAppDelegate
#synthesize window=_window;
#synthesize tabBarController=_tabBarController;
#synthesize tweets;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.tabBarController.delegate = self;
// Override point for customization after application launch.
// Add the tab bar controller's current view as a subview of the window
// Add the view controller's view to the window and display.
responseData = [[NSMutableData data] retain];
tweets = [NSMutableArray array];
NSURLRequest *request = [NSURLRequest requestWithURL:
[NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/search/json?location=-15.815347,-47.9164097&radius=500&types=restaurant&sensor=true&key=AIzaSyBLY-lBALViJ6ybrgtOqQGhsCDQtsdKsnc"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
#pragma mark NSURLConnection delegate methods
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[responseData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
[responseData release];
NSDictionary *results = [responseString JSONValue];
NSMutableArray *allTweets = [results objectForKey:#"results"];
//This is the part that I get an ERROR
[viewController setTweets:allTweets];
[window addSubview:viewController.view];
[window makeKeyAndVisible];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSDictionary *aTweet = [tweets objectAtIndex:[indexPath row]];
cell.textLabel.text = [aTweet objectForKey:#"name"];
cell.textLabel.adjustsFontSizeToFitWidth = YES;
cell.textLabel.font = [UIFont systemFontOfSize:12];
cell.textLabel.minimumFontSize = 10;
cell.textLabel.numberOfLines = 4;
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.detailTextLabel.text = [aTweet objectForKey:#"vicinity"];
NSURL *url = [NSURL URLWithString:[aTweet objectForKey:#"icon"]];
NSData *data = [NSData dataWithContentsOfURL:url];
cell.imageView.image = [UIImage imageWithData:data];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}

Answer 1

Probable you are wrong here. You are checking object, instead of value.
NSMutableArray *allTweets = [results valueForKey:#"results"];
Jope your problem is resolved.
