Double action on button click - ios

First, I'm a new iOS developer.
I has 2 UITableView.
First UITableView use for Search.
Second UITableView use for see information.
I'm create button for go to second UITableView
press control+drag button to second UITableView.
And set identifier is "gotoF10"
If click button. Connector will get #"special_selected_f10" to process at requestEWIServiceFinish method.
- (IBAction)btnf10
{
NSMutableDictionary *content = [NSMutableDictionary dictionary];
[content setValue:[[AppSetting sharedInstance] token] forKey:#"ewitoken"];
];
[[EWIConnector connector] requestEWIService:#"special_selected_f10" requestData:content delegate:self];
}
If has #"special_selected_f10" from below code. It will follow Identifier name for go to second UITableView and response data.
- (void) requestEWIServiceStart:(EWIConnector *)connector{
NSLog(#"start %#",connector.endpoint);
}
- (void) requestEWIServiceFinish:(EWIConnector *)connector responseData:(NSDictionary *)responseData{
NSLog(#"finish %#",connector.serviceName);
NSLog(#"response %#",responseData);
if ([connector.serviceName isEqualToString:#"special_selected_f10"])
{
NSLog(#"finish %#", connector.serviceName);
NSDictionary *content = responseData[#"content"];
NSString *stAlertMes = [content objectForKey:#"alertMessage"];
stAlertMes = [self getString:stAlertMes];
NSLog(#"AlertMSG : %#", stAlertMes);
if (![stAlertMes isEqualToString:#""])
{
NSLog(#"ALERT MESSAGE : %#", stAlertMes);
gloablOnWherehouse.arTableDataSelected = [[NSArray alloc] init];
}
else
{
NSLog(#"HAS DATA");
gloablOnWherehouse.arTableDataSelected = [content objectForKey:#"DataList_SPI_DetailF10Collection"];
[self performSegueWithIdentifier:#"gotoF10" sender:nil];
//labelStatus.text = #"";
}
}
else
{
NSLog(#"response %#",responseData);
}
}
This is a code from second UITableView for response data.
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"DisplayEffectQtyViewCell";
DisplayEffectQtyViewCell *cell = [self.tableViewDetailList dequeueReusableCellWithIdentifier:simpleTableIdentifier forIndexPath:indexPath];
if(cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"DisplayEffectQtyViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
} else {
if (globlOnDisplayEffect.arTableDataSelected) {
NSMutableArray *myMutbleArray = [[NSMutableArray alloc] init];
[myMutbleArray addObject:globlOnDisplayEffect.arTableDataSelected];
if (myMutbleArray)
{
NSDictionary *myDic = [globlOnDisplayEffect.arTableDataSelected objectAtIndex:indexPath.row];
NSDictionary *cont = [myDic objectForKey:#"DataList_SPI_DetailF10"];
NSString *f10_cmpt = [self getString:[cont objectForKey:#"f10_cmpt"]];
NSString *f10_dt = [self getString:[cont objectForKey:#"f10_dt"]];
NSString *f10_item = [self getString:[cont objectForKey:#"f10_item"]];
NSString *f10_lot = [self getString:[cont objectForKey:#"f10_lot"]];
NSString *f10_model = [self getString:[cont objectForKey:#"f10_model"]];
NSString *f10_of = [self getString:[cont objectForKey:#"f10_of"]];
NSString *f10_semi = [self getString:[cont objectForKey:#"f10_semi"]];
NSString *f10_tm = [self getString:[cont objectForKey:#"f10_tm"]];
NSString *f10_uncmp = [self getString:[cont objectForKey:#"f10_uncmp"]];
[cell setf10_cmpt:f10_cmpt setf10_dt:f10_dt setf10_item:f10_item setf10_lot:f10_lot setf10_model:f10_model setf10_of:f10_of setf10_semi:f10_semi setf10_tm:f10_tm setf10_uncmp:f10_uncmp];
}
}
}
return cell;
}
From upper is a concept of my application.
But, When i'm click button.
From debug IBAction isn't take #"special_selected_f10" to check on "requestEWIServiceFinish" method.
It's go to second UITableView and response empty data. Before back to first UITableView and follow from my concept again.
So, My application has 2 second UITableView when i'm click button.
(empty second UITableView and work second UITableView)
I can a little speak English.
Sorry for my bad English language.

UICollectionView Displays empty

Hi in my application in trying display the Flickr images in my UICollectionView but it shows a empty View Control
My code for display the Flickr images.
{

NSMutableArray *photoSetNames;
NSMutableArray *photoids;
}
viewDidLoad code.
- (void)viewDidLoad
{
[super viewDidLoad];

}
I have used the above to display the Flickr images in UICollectionView but its coming as a empty view please tell me how to resolve this issue.
Thanks.
At the end of -(void)loadFlickrPhotos method, call reloadData on your UICollectionView. You need to tell UICollectionView to refresh its data.
Try [self.collectionview reloadData]
I don't see that you're assigning a delegate or data source. Or for that matter, created your UICollectionView.

if-statement ios check json parameter

I'm currently parsing a JSON-feed to my table view in my iOS app. In the JSON-feed there's two different types of posts: "type":"post" and "type":"shared".
When I click on a cell in the Table View, a new view opens with the full posts etc. What I need is to set an if-statement in the didSelectRowAtIndexPath, saying: "If type = post, open this view. Else if type = shared, open this view". So I need to somehow check the json-parameter type. And based on that go to the two different views.
The didSelectRowAtIndexPath method currently looks like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//getting the data I'm passing to the next view, where movies = NSMutableArray
NSDictionary *movie = [self.movies objectAtIndex:indexPath.row];
// Allocating the Second View I want to open
HomePostsObject *newView = [[HomePostsObject alloc] init];
// passing the data to newView
newView.theMovie = movie;
// presenting the view
[self.navigationController pushViewController:newView animated:YES];
}
And the full code for parsing the data looks like this:
#implementation HomeViewController
#synthesize profilePic;
#synthesize tableView = _tableView, activityIndicatorView = _activityIndicatorView;
#synthesize btnFaceBook, btnTwitter, btnTwitter2;
#synthesize strURLToLoad;
#synthesize movies;
#synthesize statsHome;
#synthesize fontForCellText;
#synthesize twitterFollowers;
#synthesize facebookLikes;
#synthesize instagramFollowers;
- (void)viewDidLoad
{
[super viewDidLoad];
// Initializing Data Source
movies = [[NSMutableArray alloc] init];

NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
self.movies = [[NSArray alloc] initWithArray:JSON];
[self.activityIndicatorView stopAnimating];
[self.tableView reloadData];
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(#"Request Failed with Error: %#, %#", error, error.userInfo);
}];
[operation start];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return movies.count;
}

if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"HomeFeedView" owner:self options:nil];
cell = [nib objectAtIndex:0];
cell.backgroundColor = [UIColor clearColor];
}
NSDictionary *movie = [self.movies objectAtIndex:indexPath.row];
cell.title.text = [movie objectForKey:#"message"];
cell.published.text = [movie objectForKey:#"published"];
cell.twitterName.text = [movie objectForKey:#"celebname"];
return cell;
}

}

}
- (NSString *)getTwitterName
{
return #"celebname";
}
- (CGFloat)getHeightForText:(NSString *)strText
{
CGSize constraintSize = CGSizeMake(cellTextWidth, MAXFLOAT);
CGSize labelSize = [strText sizeWithFont:fontForCellText constrainedToSize:constraintSize lineBreakMode:NSLineBreakByWordWrapping];
NSLog(#"labelSize.height = %f",labelSize.height);
return labelSize.height;
}
#end
JSON structure/data:
{
"message":"blablablabla",
"published":"5 hours ago",
"link":"http://google.com",
"unix":1395493814,
"name":"Name",
"story":null,
"picture":"some-pic.jpg",
"type":"shared"
},
{
"message":"blablabla",
"published":"5 hours ago",
"name":"Name",
"unix":1395493814,
"type":"post"
},
In your HomeFeedView.h just add a new property say type.
#property(strong, nonatomic) NSString *type;
Then set this type property in cellForRowAtIndexPath delegate method.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpleTableIdentifier = #"HomeFeedView";
HomeFeedView *cell = (HomeFeedView *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"HomeFeedView" owner:self options:nil];
cell = [nib objectAtIndex:0];
cell.backgroundColor = [UIColor clearColor];
}
NSDictionary *movie = [self.movies objectAtIndex:indexPath.row];
cell.title.text = [movie objectForKey:#"message"];
cell.published.text = [movie objectForKey:#"published"];
cell.twitterName.text = [movie objectForKey:#"celebname"];
cell.type = [movie objectForKey:#"type"];
return cell;
}
and didSelect method write this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//getting the data I'm passing to the next view, where movies = NSMutableArray
HomeFeedView *cell = [tableview cellForRowAtIndexPath:indexPath];
if([cell.type isEqualToString: #"post"]){
// Allocating the Second View I want to open
HomePostsObject *newView = [[HomePostsObject alloc] init];
// passing the data to newView
newView.theMovie = [self.movies objectAtIndex:indexPath.row];
// presenting the view
[self.navigationController pushViewController:newView animated:YES];
}
else{
// Allocating the Second View I want to open
HomePostsObject *newView = [[HomePostsObject alloc] init];
// passing the data to newView
newView.theMovie = [self.movies objectAtIndex:indexPath.row];
// presenting the view
[self.navigationController pushViewController:newView animated:YES];
}

The table view data is downloading the Twitter post on the launch, even if I have set it to download the Facebook posts. It's very strange... Please help me fix this!
There's a couple of things you need to do. Firstly, you need to set the selected segment index. Before you call [self issueLoadRequest] in viewDidLoad, you should set the selected index like this:
changeData.selectedSegmentIndex = 0;
This will set the first segment to be the selected segment. Also, you'll need to make sure the correct data is loaded when you change the selected segment. To do that, you should add the following to viewDidLoad:
[changeData addTarget:self action:#selector(segmentedControlSelectedIndexChanged:) forControlEvents:UIControlEventValueChanged];
And the companying method, segmentedControlSelectedIndexChanged:
- (void)segmentedControlSelectedIndexChanged:(id)sender
{
[self issueLoadRequest];
}
Now whenever you changed between the Facebook segment and the Twitter segment, it will call the corresponding API, download the data, and update the table view. Depending on the speed on your connection, there may be a small, but noticeable delay between selecting the segment and the table view updating.

How to split data between 2 UITableViews on same View

As an example, I am trying to load a place name into my top UITableView, called myTableView. On the bottom, I am trying to display only "test2."
Naturally, all the data is being loaded into each UITableView. If I scroll to the bottom of myTableView2, the word "test2" IS shown, but I would like it to be the only thing there.
Is there a way, maybe by delegating different data sources, that I can separate the data I wan in each UITableView? I tried separating by if statements but quickly realized that had no effect.
It seems to me that I may need to set a separate datasource for myTableView2, but I am not sure how to do that...
Code is here:
- (void) connectionDidFinishLoading:(NSURLConnection *)connection
{
[self setString];

Solved with the code below. The key was to have two different arrays to load the respective data in, and display it at the very bottom where I am able to distinguish between UITableViews with IF statements:
- (void) connectionDidFinishLoading:(NSURLConnection *)connection
{
[self setString];
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];
NSString *string1 = [dic objectForKey:#"name"];
NSString *string2 = [NSString stringWithFormat:#"test2"];
for (NSDictionary *diction in dic)
{
[array addObject:string1];
[array2 addObject:string2];
[[self myTableView] reloadData];
[[self myTableView2] reloadData];
}
[indicator stopAnimating];
indicator.hidden=YES;
[indicator removeFromSuperview];
ilabel.hidden = YES;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.myTableView)
{
if ([[array objectAtIndex:indexPath.row] isKindOfClass:[NSNumber class]])
{
cell.textLabel.text = [[array objectAtIndex:indexPath.row] stringValue];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
}
else
{
cell.textLabel.text = [array objectAtIndex:indexPath.row];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
}
}
if (tableView == self.myTableView2)
{
if ([[array2 objectAtIndex:indexPath.row] isKindOfClass:[NSNumber class]])
{
cell.textLabel.text = [[array2 objectAtIndex:indexPath.row] stringValue];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
}
else
{
cell.textLabel.text = [array2 objectAtIndex:indexPath.row];
cell.textLabel.textColor = [UIColor whiteColor];
cell.textLabel.textAlignment = NSTextAlignmentCenter;
}
}
return cell;
}
