Values changing in tableview after performing search - ios

I'm getting correct data after loading the page as shown in this screen
getting correct data even after performing search like this image
but after search is cancelled im getting wrong data (label should be ph:+ and Fax:+ but its displaying both as Fax:+ like this
with this code
#implementation Staffdir
#synthesize tableview,filteredContentList,searchBar1;
- (void)viewDidLoad {
searchBar1.delegate = self;

Image in a Table View Cell when using SearchBar

I'm developing an app in Xcode in Objective-C.
The app has a TableView with an array of restaurants. My problem is that when I try to use the SearchBar I use the Title (name of the restaurant as a filter) but when I show the rows after the filter search, only the Title is right. The other label and the image in the cell is wrong (it shows me the correct title but the image and the other label (description label) is the same as the first row in the original tableview).
I have to change my cellForRowAtIndexPath method but I don't now how to change it.
This is TableViewController called MainTableViewController.h
#import <UIKit/UIKit.h>
#interface MainTableViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate>
#property (weak, nonatomic) IBOutlet UIBarButtonItem *barButton;
//#property (nonatomic, strong) NSArray *Images;

#interface RestTableViewCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;

#property (strong, nonatomic) IBOutlet UIImageView *RestImage;
#end
This is my problem graphically:
Obviously, you just apply the filter condition to the Title array, and not filtering the Images and Description array.
So you need to two more NSMutableArray to hold the filtering results for Images and Description.
But I recommend you to build a new Model for your results. Sample code for your reference:
Model layer: Restaurant.h
#interface Restaurant : NSObject
#property (nonatomic, copy) NSString *title;
#property (nonatomic, copy) NSString *desc;
#property (nonatomic, copy) NSString *image;
- (instancetype)init:(NSString *)title descripiton:(NSString *)description image:(NSString *)image;
#end
Restaurant.m
#implementation Restaurant
- (instancetype)init:(NSString *)title descripiton:(NSString *)description image:(NSString *)image {
self = [super init];
if (self != nil) {
self.title = title;
self.desc = description;
self.image = image;
}
return self;
}
#end
RestViewController.h
#interface RestViewController : UIViewController
#property (nonatomic, strong) Restaurant *DetailModal;
#end
MainTableViewController.m
#interface MainTableViewController ()
#property (nonatomic, strong) NSArray<Restaurant *> *originData;
#property (nonatomic, strong) NSMutableArray<Restaurant *> *filteredRest;
#property (nonatomic, assign) Boolean isFiltered;
#end
#implementation MainTableViewController
#synthesize mySearchBar, filteredRest, isFiltered, originData;
- (void)viewDidLoad {
[super viewDidLoad];
originData = #[
[[Restaurant alloc] init:#"80 Grados" descripiton:#"Barrio Malasaña" image:#"80_grados.png"],
[[Restaurant alloc] init:#"90 Grados" descripiton:#"Barrio Retiro" image:#"90_grados"]
];
filteredRest = [NSMutableArray new];
isFiltered = NO;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
//return _Title.count;
if (isFiltered == YES) {
return filteredRest.count;

}
}

cell.TitleLabel.text = [filteredRest objectAtIndex:indexPath.row].title;
cell.DescriptionLabel.text = [filteredRest objectAtIndex:indexPath.row].desc;
cell.RestImage.image = [UIImage imageNamed:[filteredRest objectAtIndex:indexPath.row].image];
} else {
cell.TitleLabel.text = [originData objectAtIndex:indexPath.row].title;
cell.DescriptionLabel.text = [originData objectAtIndex:indexPath.row].desc;

}

With building a new model object for your information is very efficient, so you don't need to apply there filter to three array, you just need to search once, and results will be kept kept in one array.
PS: One more tips for your coding style, naming the variable, object instance with starting lowercase, and naming the class with starting uppercase is best practise when writing OC codes. e.g., TitleLabel should rename to titleLabel, etc...
Here you are filtering cell and reusing them.
You are just replacing text. You need to replace the image and data as well.
if (isFiltered == YES) {
cell.TitleLabel.text = [filteredRest objectAtIndex:indexPath.row];
} else {
int row = [indexPath row];
cell.TitleLabel.text = _Title[row];
cell.DescriptionLabel.text = _Description[row];
cell.RestImage.image = [UIImage imageNamed:_Images[row]];
}
I am not sure but I think you have not clearly understood concept of reusable cell. You will be reusing cell which are not in the view what that means is iOS framework will give you one of the already used cell so that it doesnt have to recreate cell everytime in your case thats first cell 80Grados.
So, after you receive that cell, you replace the title but leave all other content alone. That is why you see old content with new Title Label.
What you need to do here is create a wrapper class, which will have three properties text, description and imagefile name.
#class Restaurant
#property NSString *title;
#property NString *description;
#property NSString *image;
#end
Combine your logic with this rather than treating all data as separate array. That will be extremely easy to maintain. In future you can easily fill that class with data coming from server, user entered or any otherway. Handling data in 3 different array is not very sustainable model.
So create wrapper class, fill data by creating NSMutableArray/NSMutableDictionary. Rather than putting title, fill entire wrapper object.
[filteredRest addObject: restaurantObj];
And change your code this way
Restaurant *r;
if (isFiltered == YES) {
r = [self.filteredRest objectAtIndex:indexPath.row];
} else {
r = [self.restaurantList objectAtIndex:indexPath.row]];
}
cell.TitleLabel.text = r.title;
cell.DescriptionLabel.text = r.description;
cell.RestImage.image = [UIImage imageNamed:r.image];
Let me know if any of the ideas are not clear. This is just a prototype, you will have to change your code in multiple places but would highly recommend making these changes sooner than later.

Also I uploaded working project here
http://www.filedropper.com/needcustomcell
In your
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
Cell *cell;
// rest of your code
}
that would do it. You have used UITableViewCell you need to replace ot with your custom cell class.

ViewController not properly sending over NSURL data to Destination ViewController

When a user taps a cell, I want itemURL to be set to that cells "Item URL" property. Once it does this, it should then send over the itemURL in prepareForSegue over to WebViewController, as I've attempted to do. When I have WebViewController NSLog the itemURL property however, it comes up as null. How can I make sure the value is sent over properly?

Get image from cellForRowAtIndexPath to didSelectRowAtIndexPath to push when row is selected

I'm trying to push the image from selected row to a detailed viewController. This is what I tried the latest. I also tried to get the PFFile from an PFImageView but unsuccessful.
#import "ExploreViewController.h"
#import "DetailExploreViewController.h"
#interface ExploreViewController ()
#property (strong, nonatomic) PFGeoPoint *userLocation;
#property (weak, nonatomic) UIImage *imagine;
#property (weak, nonatomic) NSString *discovery;
#end
- (PFQuery *) queryForTable
{
if (!self.userLocation) {
return nil;
}
PFQuery *query = [PFQuery queryWithClassName:#"HomePopulation"];
[query whereKey:#"geopoint" nearGeoPoint:self.userLocation withinKilometers:15];
query.limit = 25;
//[self getLocation];
return query;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object
{
static NSString *simpleIdentifier = #"ExploreCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleIdentifier];
}
cell.textLabel.text = [object objectForKey:#"discovery"];
PFFile *getImage = [object objectForKey:#"imageFile"];
[getImage getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
cell.imageView.image = [UIImage imageWithData:data];
NSLog(#"hojla: %#", cell.imageView.image);
} else {
cell.imageView.image = [UIImage imageNamed:#"1bar.jpg"];
}
}];
return cell;
}
- (void)tableView:(UITableView *)tableViewer didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self tableView:tableViewer cellForRowAtIndexPath:indexPath];
self.discovery = cell.textLabel.text;
NSLog(#"the text: %#", self.discovery);
self.imagine = cell.imageView.image;
NSLog(#"ajde: %#", self.imagine);
}
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"toDetail"]) {
DetailExploreViewController *destViewController = segue.destinationViewController;
destViewController.theImage = self.imagine;
destViewController.theString = self.discovery;
}
}
DetailExploreViewController.h
#import <UIKit/UIKit.h>
#interface DetailExploreViewController : UIViewController
#property (strong, nonatomic) NSString *theString;
#property (strong, nonatomic) UIImage *theImage;
#end
DetailExploreViewController.m
#import "DetailExploreViewController.h"
#interface DetailExploreViewController ()
#property (weak, nonatomic) IBOutlet UIImageView *theImageView;
#property (weak, nonatomic) IBOutlet UILabel *theLabel;
#end
#implementation DetailExploreViewController
#synthesize theString, theLabel, theImageView, theImage;
- (void)viewDidLoad
{
[super viewDidLoad];
theLabel.text = theString;
theImageView.image = theImage;
}
In your cellForRowAtIndexPath you are creating a new UIImageView to contain your image, but not doing anything with it. Once you have the image you can just assign it to the cell's imageView.image property -
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object
{
static NSString *simpleIdentifier = #"ExploreCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleIdentifier];
}
cell.textLabel.text = [object objectForKey:#"discovery"];
PFFile *getImage = [object objectForKey:#"imageFile"];
[getImage getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
cell.imageView.image = [UIImage imageWithData:data];
NSLog(#"hojla: %#", cell.imageView.image);
}
else {
//TODO - Put some placeholder/"not found" image into cell.imageView.image
}
}];
return cell;
}
Then, in your didSelectRowAtIndexPath -
- (void)tableView:(UITableView *)tableViewer didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableViewer cellForRowAtIndexPath:indexPath];
UILabel *label = cell.textLabel
NSLog(#"the text: %#", label.text);
UIImageView *img = cell.imageView;
NSLog(#"ajde: %#", img.image);
}
Try sending a message to the detail controller instead of using the dot syntax like so:
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"toDetail"]) {
DetailExploreViewController *destViewController = segue.destinationViewController;
[destViewController setTheImage:self.theImage];
[destViewController setTheString:self.theString];
}
}
In the detail controller implementation file , I would set up the detail view image in the viewWillAppear method instead like so:
-(void)viewWillAppear:(BOOL)animated{
theLabel.text = theString;
theImageView.image = theImage;
}
This works for me.
Thanks to #Paulw11's advice I made it happen like this:
ExploreViewController.m
- (PFQuery *) queryForTable {
if (!self.userLocation) {
return nil;
}
PFQuery *query = [PFQuery queryWithClassName:#"HomePopulation"];
[query whereKey:#"geopoint" nearGeoPoint:self.userLocation withinKilometers:15];
query.limit = 25;
// Calling getData to populate the array at the same time as the tableView is being loaded
[self getData];
return query;
}
//Retrieving objects from Parse and adding them in a NSMutableArray
- (void)getData {
PFQuery *query = [PFQuery queryWithClassName:#"HomePopulation"];
[query whereKey:#"geopoint" nearGeoPoint:self.userLocation withinKilometers:15];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
for (PFObject *object in objects) {
Detailish *detail = [Detailish new]; // Detailish is a class for the array objects
detail.discovery = [object objectForKey:#"discovery"];
PFFile *getImage = [object objectForKey:#"imageFile"];
[getImage getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
detail.imagine = [UIImage imageWithData:data];
NSLog(#"Detail imagine: %#", detail.imagine);

}];
detail.location = [object objectForKey:#"location"];
[forDetail addObject:detail];
}
}
}];
}

Retain Cycle on Retain Cycles

I'm seeing a gradual build up of memory that I think might be a retain cycle.
When does this happen: Click on a custom cell that expands and injects a nib with 3 buttons into the expanded area. Clicking the cell again closes the cell, shrinks the cell's tablerow height, rotates an open indicator and removes the previously injected nib.
If I open and close the cell multiple times I see the memory gradually building up.
Any ideas what might be causing this would be greatly appreciated.
Sorry I don't have enough reputation to post photos.
