Create UISlider
vertical
- (void)viewDidLoad
{
[super viewDidLoad];
[self addSliderVertical];
}
-(void) addSliderVertical{
slider=[[UISlider alloc]initWithFrame:CGRectMake(20, 40, 300, 300)];// set fram your require position
CGAffineTransform trans=CGAffineTransformMakeRotation(M_PI_2);
slider.transform=trans;
[self.view addSubview:slider];
slider.minimumValue=1;
slider.maximumValue=100;
slider.continuous=NO;
[slider addTarget:self action:@selector(sliderChanhge:) forControlEvents:UIControlEventValueChanged];
}
Slider change method
-(IBAction)sliderChanhge:(id)sender
{
// here change tableview scroll offset
[self.tableView setContentOffset:CGPointMake(0, (int)slider.value) animated: YES];
}
The ball gets reflected symmetrically to its angle of approach assuming it's a completely elastic collision. That means, to get the behavior you are looking for, the ball would need to approach exactly from one line mid-point to the next without any loss of energy. Sprite Kit's physics engine will...

You'll have to 'remember' which UIViewController calls the object. This can be done for instance with a property. in .h @property (nonatomic) UIViewController *viewController; in your .m file @synthesize viewController; Before calling the method, set the property with anObject.viewController = self; Then, you'll be able to call [viewController finishedPost:self]; inside...

What you're trying to do is going to inevitably bump into some serious performance issues in one case or another. Storing all cells (and their data into memory) will quickly use up your application's available memory. On the other hand dequeueing and reloading will produce lags on some devices as...
You can do it by using Aspect Ratio property of AutoLayout. You can follow this tutorial. It gives a very nice explanation on how to scale everything up by using fix aspect ratio. http://simblestudios.com/blog/development/percentage-width-in-autolayout.html...
If use AutoLayout the use this code You try to set the UITableView properties estimatedHeight. -(void)viewWillAppear:(BOOL)animated{ _messageField.delegate = self; _tableView.estimatedRowHeight = 65.0; _tableView.rowHeight = UITableViewAutomaticDimension; } Other wise use this UITableView Delegate Method - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return 300; // your dynamic height... } ...
I think your problem is that you are using a calendar with an unset time zone. Your calculation of adding 60*60*24*2 to the current time does not account for the two days when some timezones change to and from daylight savings time. Those days are 23 and 25 hours long....

UITabBarControllerDelegate has a delegate method - tabBarController:shouldSelectViewController:, just implement it and check if user is logged in or not. e.g. - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if (isLogin) { return YES; } else{ //show your view controller here return NO; } } You can also check which view controller has...

You can do it using geometry shaders to create billboarding geometry from each vertex on the GPU. You can then either create the circles as geometry, or create quads and use a circle texture to draw them (I recommend the later). But geometry shaders are not extensively supported yet, even...
You likely need to enable "Test Mode" for your app in the AppLovin dashboard in order to force test ads to serve for your area. Please send any questions to [email protected] for further assistance.

Interesting question, I've never applied auto-layout to a text field so I was curious myself. My solution was to listen for the NSWindowDelegate method, -windowDidResize. Upon that, I would check to see if the text field was the first responder. If it was, I set it to be first responder...
Your code looks fine, it looks like you accidentally placed a breakpoint in your code, see that blue-looking arrow to the left of the green-highlighted line? Do one of the following: Go ahead and right click that and click Delete Breakpoint Drag and drop that breakpoint into your view controller...

Roll back those changes, add a InfoPlist.strings file to your project, localize it and then add the needed keys to it. For example: "CFBundleDisplayName" = "App display name"; "CFBundleName" = "App bundle name"; ...
Setting dateStyle or timeStyle will override any custom dateFormat you have set. Your date string does not conform in any way to NSDateFormatterShortStyle, which is why you are getting nil when trying to convert strings to dates. Furthermore, according to Unicode Technical Standard #35 revision 31, the timezone specifier of...
It seems that the Predicate is incorrect Try : NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"SELF.fullName contains[c] %@", searchText]; ...

Because you are using reusable cells when you try to select a cell that is not in the screen anymore the app will crash as the cell is no long exist in memory, try this: if let lastCell = self.diceFaceTable.cellForRowAtIndexPath(lastIndexPath) as!

In initializeSettingsView() add nibView.setTranslatesAutoresizingMaskIntoConstraints(false). And then in viewDidload add the hight constraint to settingsView constraints.append(NSLayoutConstraint(item: settingsView, attribute: .Height, relatedBy: .Equal, toItem: nil, attribute: .NotAnAttribute, multiplier: 1.0, constant: 90.0)) And you do not need to set the position of settingsView, since it will be layout at the right position based on...

The official documentation for -setImage:forSegmentAtIndex: says A segment can only have an image or a title; it can’t have both. There is no default image. So, no, there is no way to do what you want using the image and title properties. However, there are a few options to accomplish...

You just need to add this to your code in viewDidLoad. self.tableView.tableFooterView = [[UIView alloc]initWithFrame:CGRectZero]; EDIT: sorry i was written in objective -c here is in swift. self.tableView.tableFooterView = UIView(frame:CGRectZero) The tableview will display what appear to be extra blank rows to fill out the bounds if there are not...
How about -searchBarTextDidEndEditing: in UISearchBarDelegate?

When a type isn't specified, Swift will create a String instance out of a string literal when creating a variable or constant, no matter the length. Since Strings are so prevalent in Swift and Cocoa/Foundation methods, you should just use that unless you have a specific need for a Character—otherwise...
You need to use UITextField instead of UILabel. When you insert a new cell, set this UITextField's enabled property to true. When loading all the other cells remember to set it to false to disable editing (the same cell maybe used at more than one place)....

viewWithTag: is a very fragile way to get a reference to views, and isn't recommended. But what I think is happening is that you need to call viewWithTag: on cell.contentView rather than the cell itself. I'd recommend creating proper IBOutlets to hold your imageview and label....
It's crashing because your handler object is getting released and deallocated right after the call to handler.sendMessage(), and then a delegate callback is attempted on that now-deallocated object when you try to send or hit cancel. The object is getting released and deallocated because nothing is holding a strong reference...

You can register your textField for value change event: [textField addTarget: self action:@selector(textFieldDidChange) forControlEvents:UIControlEventEditingChanged]; and in textFieldDidChange function update your label: - (void)textFieldDidChange { label.text = textField.text; } The function shouldChangeCharactersInRange is needed more for taking desisions whether to allow upcoming change or not...
Yes, this is possible using CloudKit. You'll need a CKContainer, and you'll ask it to fetch the user record ID. That record ID is unique for your apps, but is also stable for that user this means the same iCloud account will have the same record ID, regardless of which...
Based on the comments on the question, you mentioned that the words will never change. You could potentially create a whole bunch of if/else statements checking every word selected against every word in an array. I have put this down as a more efficient alternative and it should hopefully work....
No, you don't have to use both. Either you go with reloadCell technique or cell updates via beginUpdate and endUpdate. When you are reloading a particular row, internally table view system creates 2 cell and then blends in the new one with. You can remove the beginUpdates and endUpdates and...
