How to fix the postion of splitDividerView in NSSplitViewController
I had been search for years,but it doesn't work.Please help,Thanks!
Once this app start,the left view width is 150,but still i can resize both of the left and right view by dragging the splitDividerView. I have attatached a screenshot for reference
override func viewDidLoad() {
super.viewDidLoad()
self.splitView.wantsLayer = true
self.splitView.setPosition(150, ofDividerAt: 0)
}
screenshot for reference
I add two container view which is use for managing NSViewController , so get rid of NSSplitView and will save you hours

I have created the following scene:
Application scene
The scene contains a stackView with all other views contained inside of it. The grey area is a UIView which gets three subviews added to it during viewDidLoad. I want each of these views to fill the UIView and be constrained to its bounds. When one of the three buttons is clicked, the corresponding view is brought to the front of for display. The issue I am facing is that the subviews are not being constrained to the UIView. I've tried quite a few different options but cannot seem to get the effect I am looking for. The red in the following image is the background of one of the loaded subviews.

On larger devices, the subviews overextend the boundary on the right side as well. How do I constrain the subViews to my UIView boundary?
Set the frame of the 3 views you want to be constrained with the bounds of the grey superview. This can be done in layoutSubviews of the grey view or in viewDidLayoutSubviews of the viewController.
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
subview0.frame = greyView.bounds
subview1.frame = greyView.bounds
subview2.frame = greyView.bounds
}
or within the custom class for the grey view (if you have defined a custom class)
override func layoutSubviews() {
super.layoutSubviews()
subview0.frame = bounds
subview1.frame = bounds
subview2.frame = bounds
}
Can also be done by using constraints to constrain the subviews to their superview.
So I am presenting an NSViewController as a sheet of a window that has resize disabled.
The view controller that is presented as a sheet can still be resized.
How do I disable resizing of a NSViewController?
Swift 4:
override func viewDidAppear() {
// any additional code
view.window!.styleMask.remove(.resizable)
}
By the way you can do this without writing code, here is how:
Drag a Window Controller element to the Storyboard from the Object
Library.
Connect the Window Controller to the specific View Controller which you want to disable resize.
On the Window Controller's Attributes uncheck Resize option.
After some more trying I found out this did the trick in viewDidLoad:
self.preferredContentSize = NSMakeSize(self.view.frame.size.width, self.view.frame.size.height);
If you add these methods, the issue will be fixed.
- (void)updateViewConstraints NS_AVAILABLE_MAC(10_10) {
[super updateViewConstraints];
}
- (void)viewWillLayout NS_AVAILABLE_MAC(10_10) {
self.preferredContentSize = NSMakeSize(self.view.frame.size.width, self.view.frame.size.height);
}
So I have storyboard with 2 view controller's and 1 window controller. In my subclass of NSWindowController I can put my window zoomed like this:
override func windowDidLoad() {
super.windowDidLoad()
window?.zoom(self) // Or window?.setFrame(NSScreen.mainScreen()!.visibleFrame, display: true)
}
But when I want to change my window's content view controller, that size doesn't remain same size and I have to tell to zoom it again and that is ugly animation. How can I manage to keep my window's zoomed even if I change my window's content view controller?
UPDATE:
I manage to get it work. In my IBAction when my another window controller is zoomed, I did this when I want change content view controller.
secondViewController!.view.frame = contentViewController!.view.frame
contentViewController = secondViewController
I'm building a typical Xcode 6 iOS app.
My goal is:
A screen that has an sub-area that can be swiped to change the content.
For example, the home screen has a logo image, a middle area that I want to be swipeable, and a bottom button.
When the user swipes (or taps) the middle area, the area shows the next (or previous) information, which is a typical UIImage and UILabel caption.
The rest of the screen stays the same, i.e. there is no navigation change.
The code is here. It use the recommendations from the StackOverflow post here.
My question: how can I implement the code below better, while still using an XIB?
My current implementation does work, and uses this approach...
A typical Swift Demo.swift file that is a UIViewController that has:
the page index, min, and max
outlets for the PageControl, UIImageView, and UILabel
actions for the page control change, and the image swipe or tap
A typical Demo.xib file that has:
a typical UIViewController for the entire screen
a UIImageView and UILabel for the changeable image and caption text
a PageControl to indicate what tutorial page the user is viewing
I am seeking better ways to accomplish this; I've read many of Xcode tutorials and so far none seem definitive for Xcode 6, XIBs, and Swift.
Here are some implementations that I've researched that seem promising...
Is there a way to implement a subview area in the XIB?
For example, can Xocde show the XIB with a rectangular area that is intended for the changeable content?
Is there an idiomatic way to write the code for changeable content?
For example, by using a ScrollView, perhaps that contains a UIPageViewController?
Is there a way to make a PageControl XIB object large enough to cover the entire UIImageView and UILabel, so I can skip making the UIImageView respond to gestures.
In my Xcode, the PageControl seems to have an uneditable height that is always 37.
The bounty will be for expert advice.
To make a UIPageViewController swipe-able you should implement the UIPageViewControllerDataSource protocol and provide a view controller for the pageViewController(pageViewController:viewControllerBeforeViewController) -> UIViewController? and the ...viewControllerAfterViewController) methods.
Provide a custom view controller for each page that presents an image and label and takes them as properties so you can provide them from the PageViewController.
My trick it to create a method that instantiates a new view controller in these methods:
// MARK:- UIPageViewControllerDataSource
extension MyPageViewController: UIPageViewControllerDataSource {
func viewControllerWithIndex(var index: Int) -> UIViewController! {
let viewController = storyboard?.instantiateViewControllerWithIdentifier("MyViewController") as! MyViewController // This VC has to be in the storyboard, otherwise just use MyVC()
// Adjust the index to be cyclical, not required
if let count = data?.endIndex {
if count == 1 && index != 0 { return nil }
if index < 0 { index += count }
index %= count
}
viewController.view.tag = index
viewController.record = data?[index]
return viewController
}
func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
let index = viewController.view?.tag ?? 0
return viewControllerWithIndex(index + 1)
}
func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
let index = viewController.view?.tag ?? 0
return viewControllerWithIndex(index - 1)
}
func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int {
return countAndSetupPageControl()
}
func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int {
return viewController?.view.tag ?? 0
}
}
Now for the "sub-area" you will need to implement a ChildViewController. If you're using storyboards you can just drag a Container View and put PageViewController in the embedded view controller, otherwise you need to add the PageViewController.view as a subview and set the frame to the middle.
You can find more info in the apple documentation but basically you MUST call these methods:
addChildViewController(pageViewController)
view.addSubView(pageViewController.view)
pageViewController.view.frame = ... // This is your "sub-area"
pageViewController.didMoveToParentViewController(self)
If you add a height constraint to PageControl you can set it's height to whatever you want.
I don't see a problem with your current implementation. Changing it to use a PageViewController would be quite more work.
If I were you I would add an animation in pageUpdate function so the image would fade in or slide in...
It would only make sense to use a PageViewController if you want to be able to scroll to the next page (as in content moving in the same time your finger is moving onscreen). And you can use a PageViewController or a CollectionView with paging enabled.
I've searched a lot on the internet for a solution to this problem but I can't figure it out. I'm trying to create a custom cell in a table view.
I made a CustomCell.swift class to configure the labels I want in my custom cell, created it via storyboard (the first prototype cell in the tableview) and linked it with a identifier to the cellForRowAtIndexPath method
override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
let cellIdentifier = "huisCell"
var cell: CustomCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? CustomCell
if cell == nil {
cell = CustomCell(style: UITableViewCellStyle.Value1, reuseIdentifier: cellIdentifier)
}
cell!.huisAdresLabel.text = "123"
cell!.huisDetailLabel.text = "456"
return cell
}
My CustomCell.swift code is like this:
class CustomCell: UITableViewCell {
#IBOutlet var huisAdresLabel: UILabel
#IBOutlet var huisDetailLabel: UILabel
}
It's very basic now, but I just want it to work because than I can expand the cell with more attributes and style it better.

I hope someone can explain what I'm doing wrong.
Edit:
To clear up some things, before my try to make a custom cell, I got it working with the basic cells, with the one label on the left hand side. But when I tried to style the tableview and created a custom cell it won't work.
Also, when testing different solutions I came across the problem that de two labels in CustomCell.swift are nil. Even when I made a custom init and did like a
self.huisAdresLabel = UILabel()
it was still nil. in the code that I showed you it prints the following:
<UILabel: 0xb2aadc0; frame = (0 -21; 42 21); text = '123'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <_UILabelLayer: 0xb2aa3a0>>
I resolved this issue by overriding the following function, setting the height of the cells manually:
override func tableView(tableView:UITableView!, heightForRowAtIndexPath indexPath:NSIndexPath)->CGFloat
{
return 44
}
Try using a xib file and adding your custom cell class to the
"Table View Cell" that you create in your xib file.
(Make sure you reconnect it to the outlets in your custom cell class ;)

I had the same Problem, but after disabling the "Use Auto Layout" under the "File Inspector", it did work!! and the Custom Cells are displayed
Note: I made the Custom Cells in the Builder, not in Code. Using Xcode beta 3
Working w/ Custom table cells in Xcode 6 Beta-4's IB, I found they all rendered on top of each other and my non-Custom cell.
I fixed my problem by...
selecting the Custom cell in IB
selecting the Size inspector (Option-Command-5)
in the Table View Cell section
checking the Custom box
keeping the default-provided 44 Row Height
Quick workaround: disable Use Size Classes, but still don't know is it bug or feature :-) needs more investigation or man reading.
