detailtableview controller to push the image from tableview - ios

Question

hi I'm trying to view the image and description form tableview to detailviewcontroller but not I'm not able get it. I'm fetching the image form server i have stored the image url and using the json and php coding I'm getting the image url using the NSURLConnectionDelegate viewing the images and description in tableview .
i have trying many ways to view those images in the tableview but getting the images.
detailview controller.h file coding
#import <UIKit/UIKit.h>
#import "image.h"
#class image;
#interface viewdetailpoliticalViewController : UIViewController<NSURLConnectionDelegate>
{
NSURLConnection *connection;
}
#property (strong,nonatomic) NSString *value;
#property (strong,nonatomic) UIImage *imm;
#property (strong, nonatomic) IBOutlet UIImageView *imageview;
#property (strong, nonatomic) IBOutlet UILabel *dcp
#property (strong, nonatomic) NSMutableData *responseData;
-(void)setDataSource:(image *)inImageOb;
#end
this is my detailview controller.m file coding
#import "viewdetailpoliticalViewController.h"
#import "image.h"
#interface viewdetailpoliticalViewController ()
#end
#implementation viewdetailpoliticalViewController
#synthesize imageview,dcp;
#synthesize value,imm;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.imageview.image = self.imm;
self.dcp.text = self.value;
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)setDataSource:(image *)inImageOb
{
self.value = inImageOb.desp;
NSURL *url = [NSURL URLWithString:inImageOb.img];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
self.responseData = [[NSMutableData alloc] init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data;
{
[self.responseData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
{
UIImage *image = [UIImage imageWithData:self.responseData];
self.imm = image;
}
#end
this is my tableview controller m file coding:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self performSegueWithIdentifier:#"Detailsegue" sender:indexPath];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"Detailsegue"]) {
viewdetailpoliticalViewController *detailvc = (viewdetailpoliticalViewController *)segue.destinationViewController;
NSIndexPath *indexPath =[self.mytableview indexPathForSelectedRow];
[detailvc setDataSource:[imgevery objectAtIndex:indexPath.row]];
}
}
this is code i have used to fetch the datas using json
-(void) retrieveData
{
NSURL * url = [NSURL URLWithString:getDataURL];
NSData * data = [NSData dataWithContentsOfURL:url];
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
imgevery =[[NSMutableArray alloc]init];
for (int i=0; i<json.count; i++) {
NSString * dd = [[json objectAtIndex:i]objectForKey:#"imgp"];
NSString * plae =[[json objectAtIndex:i]objectForKey:#"disp"];
image *myimg =[[image alloc]initWithimg:dd anddesp:plae];
[imgevery addObject:myimg];
}
[self.mytableview reloadData];
}
this is the code i have used for the tableview cell
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return imgevery.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier =#"Cell";
imgpoliticalCell *cell =(imgpoliticalCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell== nil) {
cell = [[imgpoliticalCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
[cell setDataSource:[imgevery objectAtIndex:indexPath.row]];
// cell.thumbImageView.image = _img;
return cell;
}

Found the problem the problem is u passing data through Setimage Source
you set image in viewDidload itself after -(void)setDataSource:(image *)inImageOb only viewDidload () will run but you assigned image to imageview in viewDidLoad() itself
- (void)viewDidLoad
{
[super viewDidLoad];
self.imageview.image = self.imm;
self.dcp.text = self.value;
// Do any additional setup after loading the view.
}
(void)connectionDidFinishLoading will run after ViewDidLoad()
SO you ve to set Image in - (void)connectionDidFinishLoading:(NSURLConnection *)connection; only which will run at last when connection didFinish so do like this
- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
{
imm = [UIImage imageWithData:self.responseData];
self.dcp.text = value;
self.imageview.image = imm;
}
Hope Now works...
