问题 I need to use a custom view into a NSMenuItem. I've created a new view XIB and customized the view in it. How can I load that view and set it in the NSMenuItem using the setView: method?

Then I've set the view outlet of the file's owner to the view in the XIB and finally

问题 What's the best practice for setting zoom factor of an image within IKImageView via NSSlider? I was able to bind a slider either to zoom in OR zoom out action of an IKImageView. Obviously, what I'd rather see is a single slider controlling both those actions. Best, if image is refreshed after each change of the slider (continuously, even if a mouse button is not released yet). 回答1: This demo explains a lot: ImageKitDemo In particular, this snippet is what I was looking for: - (IBAction)

问题 I have a bunch of constraints set up that work well at run time, but aren't reflected in my storyboard because of small errors in positioning the views. Is there any way I can have my storyboard / xib reset all views to acknowledge the constraints I have set up? If this was already asked, I apologize. I'd expect this has been asked, but my queries aren't returning helpful results. 回答1: There's an option when you click the Resolve AutoLayout Issues tab in Interface Builder called Update Frames

问题 I am trying to set an icon to be 1/3 along the width of the superview. However when I set the width it's only give me hard values as the option. Is it possible to set the x position of an object to be 1/3rd the width through the interface builder? Thanks Update: Trying to set a .leading against a .width does not appear to be an option for leading: 回答1: You should make the constraint between the icon's centerX and the superview's trailing. In the images below, first, and third refer to the

问题 I'm building a UI for a video player and trying to make sure it looks good on all devices (from iPad Pro down to iPhone SE) Unfortunately I'm having trouble with the dynamic sizing of particular elements. Specifically the UISlider and UILabel. For this question specifically I've hidden the UILabel to focus on the UISlider. Here is my setup in the Interface Builder in Xcode: The relevant portion is the constraint: Seek Bar.height = 0.1 x height This should set the UISlider at the bottom of the

问题 Using Xcode 10.1, I create a tableview on my main storyboard. In the prototype cell, I place a text label. I then create constraints to match it's center with its superview center, both horizontally and vertically. So the label should be centered in the cell. All looks good. When I choose "View as" a different device, it is misaligned horizontally. However when I run in the simulator, it appears to be working OK. Is this an Xcode bug or is there something I'm not understanding about the way

问题 Background I have a UITableView with a single cell. Inside the cell is a UILabel . The cell, called PickerTableViewCell , gets its UI from a xib and adds it to its subview. This is done because this xib is used by many different custom cells. Problem It appears that when this cell is dequeued by the table view, its width extends beyond the table views width on the right hand side. Here is the xib with the UILabel centred within the cell, followed by how it appears on the device. Notice how
