I'm trying to build conway's game of life in Xcode (for the iPad), but I can't seem to figure out how to make it reasonably sized. As it is now its 10*10 and took quite a while to put together. I don't even think this works right.

Yes, several ideas. :D
http://www.oliverfoggin.com/game-of-life/
The way I would approach building it (if I was to start again), would be to work exclusively on a class (or collection of classes) for the model of the game. i.e. the engine. (I may even put a cellular automaton engine on github).
Anyway, I presume you have looked into how the game of life works?
Size of "world"
The first thing you'll have to decide is how big you want to make the "world" in your app. I would suggest going for a finite size over an infinite size as it makes it orders of magnitude less complex.
Model
You'll need to store your cells in some sort of data structure. This could be a 2D array or something else. My initial version was a 2D array of bool values (true = alive, false = dead).
Counting Neighbours
You'll need a way of counting the number of alive neighbours for each cell.
Iterating a generation
Once you have all the above you should then be able to use these to advance your map by one generation.
Like I said, start with the data model and basic functions before you do anything visual for the app.
Once you've done that you can start working out how to display your model.
It's not a simple task and you may well have around "one thousand" lines of code at the end for you whole project.
The best way though is to dive in and just try and write it.

Here is the image slider works fine when dragging manually the image changes with page control indicator change but I want to add the timer to the following code and move the images and indicator automatically. Please help me to apply NS timer in this code and also want to move from the last image to 1st image and so on.
#implementation DashboardViewController {

[UIImage imageNamed: # "image2.jpg"],
[UIImage imageNamed: # "image3.jpg"],
[UIImage imageNamed: # "image4.png"],

nil
];
CGRect scrollFrame = CGRectMake(0, 0, self.view.frame.size.width, self.scroller.frame.size.height);
scroller.frame = scrollFrame;
self.scroller.contentSize = CGSizeMake(self.scroller.frame.size.width * animationArray.count, self.scroller.frame.size.height);

Please try this code for NSTimer (i use collectionView for easy use)
var timer : Timer?
var currentFeaturedCouponIndex = 0
//MARK: - NSTimer -
func setupTimer(){
timer = Timer.scheduledTimer(timeInterval: 5.0, target: self, selector: #selector(self.scrollFeatured), userInfo: nil, repeats: true);
}
func scrollFeatured(){
if self.arrFeaturedCoupon.count > 0 {
//Becauese we scroll coupon if total is > 1
if self.arrFeaturedCoupon.count > 1 {
if self.currentFeaturedCouponIndex < self.arrFeaturedCoupon.count - 1 {
self.currentFeaturedCouponIndex = self.currentFeaturedCouponIndex + 1
}
else {
self.currentFeaturedCouponIndex = 0
}
self.pageControl.currentPage = currentFeaturedCouponIndex
//When currentFeaturedCouponIndex == 0 we make animated: false
if self.currentFeaturedCouponIndex == 0 {
self.featuredCouponColView.scrollToItem(at: self.featuredCouponCurrentIndexPath, at: UICollectionViewScrollPosition.left, animated: false)
}
else {
self.featuredCouponColView.scrollToItem(at: self.featuredCouponCurrentIndexPath, at: UICollectionViewScrollPosition.left, animated: true)
}
}
}
}
To invalidate timer when and where you want
func invalidateTimer(){
if timer != nil {
self.timer!.invalidate()
self.timer = nil
}
}

I have a messenger, so I want to show UIMenuController on cell long tap.
I need image view to catch long press, because I have text and media messages. But I get a crash becomeFirstResponder call after I received long press gesture on iOS 8(iOS 7 works well):
*** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: 0x13fd75b90> should have parent view controller:<FriendPlay.WLDialogViewController: 0x13fd54d10> but requested parent is:<UIInputWindowController: 0x140815000>'
This is the part of code:
override func handleLongPress(longPress: UILongPressGestureRecognizer!) {
let alpha: CGFloat = 0.6
let point = longPress.locationInView(tableView)
let indexPath = tableView.indexPathForRowAtPoint(point)
if indexPath != nil {
let cell = tableView.cellForRowAtIndexPath(indexPath!) as MessageCell
let convertedPoint = longPress.locationInView(cell.balloonImageView)
if CGRectContainsPoint(cell.balloonImageView.frame, convertedPoint) {
var myView = cell.balloonImageView
if cell.message.type == MessageType.Text {
cell.balloonImageView.alpha = alpha
}
else {
myView = cell.mediaImageView
cell.mediaImageView.alpha = alpha
}
if longPress.state == UIGestureRecognizerState.Began {
showMenuAtPoint(convertedPoint, myView: myView)
}
}
}
}
private func showMenuAtPoint(point: CGPoint, myView: MessageImageView) {
myView.becomeFirstResponder()// <--- that crashes
let rect = CGRectMake(point.x, point.y, 0, 0)
let mc = UIMenuController.sharedMenuController()
mc.setTargetRect(rect, inView: myView)
let sendItem = UIMenuItem(title: "Send", action: "sendAgain:")
mc.menuItems = [sendItem]
mc.setMenuVisible(true, animated: true)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "menuDidHide:", name: UIMenuControllerDidHideMenuNotification, object: nil)
}
func sendAgain(sender: AnyObject) {
println("Send!")
}
For class MessageImageView (inherited from UIImageView) I redefine becomeFirstResponder to return always true.
I initialize my cell in - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier messageMaxWidth:(CGFloat)messageMaxWidth

Please give me some suggestions, how to fix this strange bug.
Your view controller probably has a property named inputView that is merely a subview, not an inputView as UIResponder interface expects it to be.
Starting with iOS 8 they check that UIResponder's inputView has no parent.
I'm having a problem with trying to change the colour of my navigation controller inside my popoverController.
I'm trying to do something like this:
if (self.popoverController == nil) {
ArtistsViewController *artistsViewController =
[[ArtistsViewController alloc]
initWithNibName:#"ArtistsViewController"
bundle:[NSBundle mainBundle]];
artistsViewController.navigationItem.title = #"Artists";
UINavigationController *navController =
[[UINavigationController alloc]
initWithRootViewController:artistsViewController];
UIPopoverController *popover =
[[UIPopoverController alloc]
initWithContentViewController:artistsViewController.navigationController];
artistsViewController.navigationController.navigationBar.tintColor=[UIColor greenColor];
popover.delegate = self;
[artistsViewController release];
[navController release];
self.popoverController = popover;
[popover release];
}
[self.popoverController
presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
but it doesn't work. any suggestions?
////////////////////////////////////////
////////////**SOLUTION**////////
////////////////////////////////////////
I'm gonna edit this post because i solved my problem and I think could be helpful share my solution here:
first of all, follow this sample:
http://mobiforge.com/designing/story/using-popoverview-ipad-app-development
When It is done go to step two.
The second step will be add a new popoverBackgroundViewClass:
Add new file in your project Objective class and call it 'CustomPopoverBackgroundView'
///////////////////////////////////////////////
////// CustomPopoverBackgroundView.h /////////
///////////////////////////////////////////////
#import < UIKit/UIKit.h >
#import < UIKit/UIPopoverBackgroundView.h >
#interface CustomPopoverBackgroundView : UIPopoverBackgroundView{
UIPopoverArrowDirection direction;
CGFloat offset;
}
#end
//////////////////////////////////////////////
////// CustomPopoverBackgroundView.m /////////
//////////////////////////////////////////////
#import "CustomPopoverBackgroundView.h"
#implementation CustomPopoverBackgroundView
- (void)layoutSubviews {
[super layoutSubviews];

switch (self.arrowDirection) {
case UIPopoverArrowDirectionUp:
startingTop += 13.0;
fullHeight -= 13.0;
//the image line.png will be the corner
arrow = [UIImage imageNamed:#"line.png"];
arrowCoord = (self.frame.size.width / 2) - self.arrowOffset;
arrowView = [[[UIImageView alloc] initWithFrame:CGRectMake(arrowCoord, 0, 13.0, 13.0)] autorelease];
break;
case UIPopoverArrowDirectionDown:

}
- (void) setArrowOffset:(CGFloat)arrowOffset {

[self setNeedsLayout];
}
- (UIPopoverArrowDirection)arrowDirection {
return direction;
}
- (void)setArrowDirection:(UIPopoverArrowDirection)arrowDirection {

}
+ (UIEdgeInsets)contentViewInsets {

#end
Third step:
When It is done add this line in 'PopOverExample1ViewController.m':
import the new class:
#import " CustomPopoverBackgroundView.h "
-(IBAction) showMovies:(id) sender {
if (self.popoverController == nil) {
MoviesViewController *movies =

popover.delegate = self;
[movies release];
//THIS IS THE LINE THAT YOU HAVE TO ADD
popover.popoverBackgroundViewClass=[CustomPopoverBackgroundView class];
self.popoverController = popover;
[popover release];
}
[self.popoverController
presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
-(IBAction) btnShowMovies:(id) sender {
if (self.popoverController == nil) {
MoviesViewController *movies =
[[MoviesViewController alloc]
initWithNibName:#"MoviesViewController"
bundle:[NSBundle mainBundle]];
UIPopoverController *popover =
[[UIPopoverController alloc] initWithContentViewController:movies];
popover.delegate = self;
[movies release];
//THIS IS THE LINE THAT YOU HAVE TO ADD
popover.popoverBackgroundViewClass=[CustomPopoverBackgroundView class];
self.popoverController = popover;
[popover release];
}
CGRect popoverRect = [self.view convertRect:[btn frame]
fromView:[btn superview]];
popoverRect.size.width = MIN(popoverRect.size.width, 100);
[self.popoverController
presentPopoverFromRect:popoverRect
inView:self.view

I have created a UITableView with 4 Sections and 3 Rows so totally 12 Rows. But

actually when you scroll then other rows are created in case you having more rows,so think you need to write this code like this,

Problem with your code is:
1) Cell is being reused. but the textfield what you added as subview is not removed!
2) Whenever your cellforRowAtIndex gets called, you are adding textfield each time. But you forgot that you have already added one textfield but haven't removed it.
This is the reason for overlapping.
Solution:
Subclass the UITableViewCell and add textfield in its initWithFrame method and pass the data to that cell. This will solve your problem and also this will reduce your cellForRowAtIndex method length.
Sample code:
CustomCell.h:
#import <UIKit/UIKit.h>
#class contactr;
#interface CustomTableCell : UITableViewCell
{
UITextField *mTextField;
}
#property(nonatomic , retain) UITextField *textField;
#end
CustomCell.m:
#import "CustomTableCell.h"
#synthesize textField = mTextField;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self)
{
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(100,10,200,40)];
self.textField = textField;
[textField release];
[self addSubview:self.textField];
}
return self;
}
- (void)dealloc
{
self.textfield = nil;
[super dealloc];
}
#end
Use this class as your tableViewCell.
And your cellForRowAtIndex must be:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"CELL IS NIL %i", indexPath.section);
static NSString *CellIdentifier = #"Cell";
CustomTableCell *cell = (CustomTableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[CustomTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textField.placeholder = #"";
cell.textField.text = #"";
if (indexPath.section == 0)
{
if(indexPath.row == 0)
{
cell.text = #"Tmail";
cell.textField.placeholder = #"Mandatory";
cell.textField.delegate = self;
}
else if ( indexPath.row == 1 )
{
cell.text = #"English";
cell.textField.placeholder = #"Mandatory";
cell.textField.delegate = self;
}
else

cell.textField.delegate = self;
cell.textField.textColor = [UIColor blackColor];
}
}
else if (indexPath.section == 3)
{
if(indexPath.row == 0)
{
cell.text = #"NOKIA";
cell.textField.placeholder = #"Mandatory";
cell.textField.delegate = self;
cell.textField.textColor = [UIColor blackColor];
}
else if ( indexPath.row == 1)

From your initial code, the tableview is behaving normally.
You create cells for the first 3 sections because they are visible and there are no extra cell in the table view which you can reuse.
But, whenever you get scroll to the 4th section (which is not visible at first), you start reusing cells (which happen to be the ones from the 1st section that is not out of the screen).
In order not to lose the data the user has entered in each cell you need to store each UITextField(or at least the text from it) in a separate array. When the table needs a certain cell, you look for the textfield in your array. If it's not there, create and add a new UITextField.
PS: I hope the code doesn't have any typos. I'm at work and I don't have a mac here.
