i have created a xib file in Xcode 4.2 and i am looking at getting it to the tabbed application but i have been trying and I'm a little bit new to Xcode , coding so thats why i need your help i have my code below but there are a few little errors but what i would like you lot to help me with is maybe getting to a tabbed application... well telling me what to do anyhow. heres a video for you to have a look at in case i haven't explained it correct (this is my video i did just for this question http://www.youtube.com/watch?v=e7R5_kGClM0 hope the video help but more importantly you can help me.
There is the .h but the is no errors in this
#import <UIKit/UIKit.h>
#interface myview : UIViewController <UITableViewDelegate, UITableViewDataSource, UIPickerViewDelegate, UIPickerViewDataSource>
#property (strong, nonatomic) IBOutlet UITableView* tableView;
#property (strong, nonatomic) IBOutlet UIPickerView* pickerView;
#property (strong, nonatomic) NSMutableArray* tableData;
#property (strong, nonatomic) NSMutableArray* pickerData;

This is the .m but i will break it up
#import "myview.h"
#implementation myview
#synthesize tableView, pickerView, tableData, pickerData;

this is the -(void)viewDidLoad];etc..

Here Are The Errors In The Code There are Two
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
^^^^^^^^^^^^^^^^^
**Local declaration of 'tableView hides instance variable**
Second error
[pickerView reloadAllComponents];
^^^^^^^^^^^^^^
Local declaration of 'pickerView hides instance variable
Thanks Very Much I Hope To Here From You Soon !!!
Use this, "tableView hides instance variable" occurs if local variable and instance variable have the same name.
- (UITableViewCell*)tableView:(UITableView*)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView1 dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [ [UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
and for pickerView use this
[self.pickerView reloadAllComponents];

Sunny Thank you for your reply. I made the following changes and now by clicking on a tablecell or search result, I am pushed to DetailViewController but, for any cell I click on I get the same DetailView. I need the detail view to show different information depending on the cell I click on.
I added this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
[self performSegueWithIdentifier: #"ShowDetails" sender: self];
}
}
New segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];
int row = [myIndexPath row];
detailviewcontroller.DetailModal = #[_Title[row],_Attribute[row]];
}
}
update:
The reason I am having difficulty in implementing your code is because my information to be passed to the detailview is in DetailViewController.h but as an array not a string:
#property (nonatomic,strong) NSArray *Title;
#property (nonatomic,strong) NSArray *Attribute;
in the viewdidload I get these from my plist:
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
_Title = [dict objectForKey:#"caseName"];
_Attribute= [dict objectForKey:#"attribute"];
the table view is populated with said data with the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"TableViewCell";
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView)
{
cell.textLabel.text = [self.searchResult objectAtIndex:indexPath.row];
}
else
{
cell.TitleLabel.text = self.Title[indexPath.row];
cell.AttributeLabel.text = self.Attribute[indexPath.row];
}
return cell;
}
Then in the DetailViewController.h:
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;
#property (nonatomic,strong) IBOutlet UILabel *AttributeLabel;
#property (nonatomic,strong) NSArray *DetailModal;
DetailViewController.m:
_TitleLabel.text = _DetailModal[0];
_AttributeLabel.text = _DetailModal[1];
My segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];
int row = [myIndexPath row];
detailviewcontroller.DetailModal = #[_Title[row],_Attribute[row]];
}
}
I thought it would help to put more of my code so you're able to get clearer picture. In my non expert opinion, I think the reason your code doesn't work for me is because my data is being stored in an array (DetailModal) and not in a string.
Thank you for taking the time to help me with this
You should implement TableView delegate;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
else {
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
}
Update:
You have to set the value to be displayed in the detailed view. You might declare a property in the header file for your detailView which you might set in prepareForSegue (or in the didSelectRowAtIndexPath above). For example, in DetailViewController you might do this:
#interface DetailViewController: UIViewController
#property (weak, nonatomic) NSString *myDetailValue;
#end
Then in tableView: didSelectRowAtIndexPath: above, set the correct value before you do the segue:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
// TODO select value from filteredList to set the detailViewController, e.g.:
self.detailedViewController.myDetailValue = valueFromFilteredListForIndexPath;
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
else {
// TODO select value from regular list to set the detailViewController, e.g.:
self.detailedViewController.myDetailValue = valueFromRegularListForIndexPath;
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
}
Similarly, you can do it the prepare for segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath;
if (self.inSearch) {
myIndexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
detailedViewController.myDetailValue = valueFromFilteredListForIndexPath;
}
else {
myIndexPath = [self.tableView indexPathForSelectedRow];
detailedViewController.myDetailValue = valueFromRegularListForIndexPath;
}
}
}
I cannot get my plist to display on my app. I need to use TableView and not a TableView Controller. Im not sure if I have followed the wrong code when first attempting it. Please take a look.

Feel free to ask for anything else that may help. Thanks.
Change the uitableview property to strong instead of weak. I do this to have a strong pointer to the tableview so it does not get deallicateded. Also you need to connect the delegate and datasource of the uitableview to the uiviewcontroller in the storyboard. So the protocol methods will be called in your uiviewcontroller. If they are not connected the protocol methods are not being called so nothing will show up in your table view.
If you have an array of dictionaries the fornumberofrows return [myarray count];
Connecting the datasource and delegate in the storyboard is overlooked a lot of times so check this first. I hope this helps!
Did you set Delegate and Datasource in the XIB?
Other things you need to check is ,
Put break point in below methods and check if it s firing
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Make sure you are not returning zero in the first two methods.
If either of first 2 methods are not firing then it means you did not added the datasource in XIB
I'm pretty new to xcode so I'm having trouble performing this task. I've created a table with a search bar with names that are passed to a detail view with a UILabel that shows the corresponding name of the cell clicked. The search bar works and it filters the results. I used this tutorial to help me with it:
http://www.appcoda.com/how-to-add-search-bar-uitableview/
Now I want to have an image in the detail view instead of a UILabel, that corresponds to each of the cells but I'm having trouble figuring out how to do that. Here is the code I'm working with:
TableViewController.h:
#interface SearchViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource>

So in detail, the "cards" are the names in the table. Right now, it segue to a UILabel of the name of the card and I would like to have it instead, segue to the corresponding image of the card in the regular table and filtered table when searched. I appreciate your time and help! Thanks!
I'm not sure if I understanded your question correctly, but I would use one of these three approaches:
1st:
Easiest way is to follow this tutorial
2nd: Create custom cell which you will use instead of default cell. To get you on track, you can check this good tutorial How to create custom cell. In your custom cell, you'll declare additional variable, UIImage, which will or won't be displayed in your table view. Point is, you can send it in prepareForSegue method to your detailViewController.
3rd: Create NSDictionary where you will have values (images of your items) for keys (name of item). Then, pass it in prepareForSegue to your NSDictionary in detailViewController. After that, just assign your UIImage to UIImageView in your detailViewController based on what name of item did you receive. (So you'll still be sending name and then detailImage = [yourdict objectForKey:myItemName];)
I'm writing this on my windows laptop, because I'm not at work right now (that's where I have my mac mini), so there may be some syntax errors in my answer :)
Im trying to make a small project. Could someone help me understand why the segue does not work?

The code work´s fine, and loads a tableView, but I need to go to CarDetailViewControler and I´m using the following code, but it does not work.
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"ShowCarDetails"])
{
CarDetailViewController *detailViewController =
[segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView

detailViewController.carDetailModel = [[NSArray alloc]
initWithObjects: [self.carMakes
objectAtIndex:[myIndexPath row]],
[self.carModels objectAtIndex:[myIndexPath row]],
[self.carImages objectAtIndex:[myIndexPath row]],
nil];
}
}
In the storyboard did you use a cell prototype? If so, did you control-drag from the prototype to the destination viewcontroller and create the named segue?
The method you are using requires the segue to be defined completely in the storyboard, meaning the trigger for the segue is tied to the cell prototype.
You can manually trigger a segue using:
[self performSegueWithIdentifier:#"ShowCarDetails" sender:self];
in your:
tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath as an alternative.
