I have a View Controller and in that View Controller, I have a button. On Click that button will slide in a view(ToolOptionsView). In this View I have a Collection View added but I am having this error

In the line
[self.toolsCollectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:#"toolsCell"];
you register the class UICollectionViewCell for the identifier but should actually register your custom class MenuItemCollectionViewCell:
[self.toolsCollectionView registerClass:[MenuItemCollectionViewCell class] forCellWithReuseIdentifier:#"toolsCell"];
Most probably the cell returned from dequeResuableCellWithIdentifier Is not a MenuItemCollectionViewCell.
Put a breakpoint after that method and check what tipe of cell is returned in the debugger, just write po cell.class

Good afternoon,
I would like to tap the profile image (like Facebook app) inside a row in my TableViewController using "TouchesBegan" to display a new ViewController with more information regarding the user. That means going from TableViewController (touch in the image of the TableViewCell) and then go (segue) to another ViewController called "ProfileViewController".
When I tried to do that directly in my TableViewCell it didn't worked because it's not a ViewController (it's a subclass of TableViewController) so I cannot move to a different ViewController from that.
So, what I'm trying to do now, is create a TouchesBegan in the UIImage from my TableViewController, but I get a warning (and followed by a crash) because I use a NSArray to fill the UIImage URL and it seems that I cannot assign a TouchesBegan directly to the image.
Can you help me with more information or some example? Maybe there is something I'm missing because It's my first time trying to do something like that and any help will be appreciated.
Here you are my code:
That's my TableViewController:

Thanks in advance.
If your UIImageView should act like a button, you should make it a UIButton instead of a UIImageView. With an UIButton you can set a segue in the Interface Builder. Here's an example of the UITableViewController:
class TableViewController: UITableViewController, UITableViewDataSource, UITableViewDelegate {
let dataSource = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
dataSource.addObject(UIImage(named: "image.jpg")!)
dataSource.addObject(UIImage(named: "image.jpg")!)
tableView.reloadData()
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataSource.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("tableviewcell", forIndexPath: indexPath) as TableViewCell
let image = dataSource.objectAtIndex(indexPath.row) as UIImage
cell.button.setBackgroundImage(image, forState: UIControlState.Normal)
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "pushtodetail" {
println("performing segue from a button in a cell")
}
}
}
I'm noob in Obj-c programming. I'm making an iPad application composed of a ViewController that shows me 2 text boxes , a button in the upper side , just to make a sum.
In the same Viewcontroller, i have a TableView and a Button. This Tableview initially shows me an element, but i'd want to refresh this list just clicking the button.
The function linked at the button to refresh the list ( touch down event ) is called " listaPDF " .

[lblTotale setText:totale];
[lblTotale setHidden:FALSE];
}

I have tried your code as it is.
Why you initializing UITableView object in viewDidLoad. It doesn't need to be allocated if you are adding on Xib file. If you creating UITableView Programmatically then its required. Just comment/remove that initializing line and tableView's delegate methods will be called.
And In 'ListaPDF' function no items is being added to array 'lista', that's why no new entry was visible in UITableView.
NSMutableArray indices begin at 0 - not 1
int contatore = 1;
...
[lista insertObject:files atIndex:contatore];
contatore++;
Use addObject to add an object to a NSMutableArray
[lista addObject:files];
Remove all of your instance variables, because this:
#property (nonatomic, retain) NSMutableArray *lista;
creates an instance variable called _lista - not lista
You have quite a bit of code backwards:
tabella.delegate = self;
tabella.dataSource = self;
tabella = [[ UITableView alloc] init];
lista = [[NSMutableArray alloc] init];
You're trying to set the delegate and datasource before the table is allocated.
It should be:
tabella = [[ UITableView alloc] init];
lista = [[NSMutableArray alloc] init];
tabella.delegate = self;
tabella.dataSource = self;
However the UITableView has been added inside Interface Builder, right?
That means it's already being created for you and you shouldn't be allocating the table here.
Also: inside Interface Builder you can rightclick+drag (or ctrl+leftclick+drag) to connect your UITableView to yourUIViewController as its delegate and datasource

Regards,
Finally, I solved the question myself.
To solve it, I called shouldReloadTableForSearchString in textDidChange then the incremental search worked. A diff belows:
WordsIndexViewController.m
## -16,6 +16,7 ##
#property (strong, nonatomic) NSArray *words;
#property (strong, nonatomic) NSMutableArray *searchedWords;
+#property (strong, nonatomic) UISearchDisplayController *displayController;
#end
## -52,6 +53,7 ##
searchDisplayController.searchResultsDelegate = self;
searchDisplayController.searchResultsDataSource = self;
_tableView.tableHeaderView = searchBar;
+ _displayController = searchDisplayController;
[self.view addSubview:_tableView];
}
## -132,5 +134,9 ##
}
}
}
+- (void) searchBar:(UISearchBar *)searchBar textDidChange:(NSString *) searchText {
+ [self searchDisplayController:_displayController shouldReloadTableForSearchString:searchText];
+}
#end
Thanks,
Make sure you create an iVar for the UISearchDisplayController in your header file.
If you create an UISearchDisplayController using:
UISearchDisplayController* searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchField contentsController:self];
it will get released by ARC, it will not call any delegate methods and when you'll call self.searchDisplayController (the UIViewController's property) it will be nil.
So, the fix is:
In your header (.h) file:
#interface MenuViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate> {
UISearchDisplayController* searchDisplayController;
UISearchBar *searchField;
UITableView* tableView;
NSArray* searchResults;
}
and in the implementation (.m) file:
searchField = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 49)];
searchField.delegate = self;
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchField contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
searchDisplayController.searchResultsDelegate = self;
tableView.tableHeaderView = searchField;
tableView.contentOffset = CGPointMake(0, searchField.frame.size.height);
When implemented like that, you can call both self.searchDisplayController and searchDisplayController in the rest of your code.
I'd like to start by apologising as I'm sure this question has been answered, in various forms on this site and others, but I just can't seem to implement any similar threads
It's just I have been trying to push a array of search engines into my webView,
I have populated the table with a .plist or NSMutableArray and I have an array of both kinds with Url's in I have manages to load a subview but I an really struggling to get my web view loading.
I think I'm ok until didSelectRowAtIndexPath and the webView load request. Ok thinking about it I have only populated the table and put IBOUTLET (nonatomic, retain) UIWebView *webView and synthesised it in my WebViewController.
And as Background my TableViewController is embedded in a NavigationController and a WebView in a UIViewController

What exactly is not working?
Looking at your code, I immediately see that you cell initiation code is empty
if (cell == nil) {
}
I think you should initiate your cell with something like this:
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
I'm trying to save the name of a button using a singleton so that the name can be accessed in another view to play a video with the same name. However, I'm getting the error: SIGABRT. I don't really see what's wrong with my code. Any ideas?
#import "List.h"
#import "MyManager.h"
#import "Video.h"
#implementation ExerciseList
-(IBAction) goToVideo:(UIButton *) sender{
MyManager *sharedManager = [MyManager sharedManager];
sharedManager.vidName = [[sender titleLabel] text];
Video *videoGo = [[Video alloc] initWithNibName: #"Video" bundle: nil];
[self.navigationController pushViewController: videoGo animated: YES];
[videoGo release];
}
Here is my .h and .m for MyManager:
#import <foundation/Foundation.h>
#interface MyManager : NSObject {
NSMutableArray *workouts;
NSString *vidName;
}
#property (nonatomic, retain) NSMutableArray *workouts;
#property (nonatomic, retain) NSString *vidName;
+ (id)sharedManager;
#end
#import "MyManager.h"
static MyManager *sharedMyManager = nil;
#implementation MyManager
#synthesize workouts;
#synthesize vidName;
#pragma mark Singleton Methods
+ (id)sharedManager {
#synchronized(self) {
if (sharedMyManager == nil)
sharedMyManager = [[self alloc] init];
}
return sharedMyManager;
}
- (id)init {
if ((self = [super init])) {
workouts = [[NSMutableArray alloc] init];
vidName = [[NSString alloc] init];
}
return self;
}
-(void) dealloc{
self.workouts = nil;
self.vidName = nil;
[super dealloc];
}
#end
You should access the title of the button
sharedManger.vidName = [sender currentTitle];
However you are not using ARC so also check where your vidName property is retain or copy.
if it is not retain or copy then you can use this code also
if(sharedManger.vidname != nil){
[sharedManger.vidName release];
sharedManger.vidName = nil;
}
sharedManger.vidName = [[sender currentTitle] retain];
