nslayoutconstraint

I'm fairly new to iOS development but have reached the point where I want to create my own composite UIView as a custom UIButton. I would like to layout a UILabel and 2x UIImageViews as follows; But I would also like to anchor the controls (subviews) in such a way that as the label expands, due to translations say, the view automatically handles the extra real estate. For example; Ideally - the right hand side UIView is anchored to the right; and remains a fixed width/hight (right aligned). the label and bottom image divide the remaining left hand space the label is vertically centered in the

If I have this for a child view controller: autoCompleteViewController.view.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ autoCompleteViewController.view.topAnchor.constraint(equalTo: view.topAnchor, constant: 0), autoCompleteViewController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 0), autoCompleteViewController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 0), autoCompleteViewController.view.bottomAnchor.constraint(equalTo: googleMapViewController.view.topAnchor, constant: 0), autoCompleteViewController.view

I have a UITableView with self sizing cells. Table contains 1 section and some rows. I have some rows say 30 and I want to delete row during didSelectRowAtIndexPath . When I delete a row available near the bottom of tableview (say 28th row ), the rows before 28th row changes their position and it causes jerky animation as a result of deleteRowsAtIndexPaths . See attached gifs for more details. Cells constructed with frame deletion animation Auto Resizing cells Deletion animation - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } -(CGFloat)tableView:(UITableView *

How to work with IB Constraints and NSLayoutConstraint ? I want to programmatically fine-tune my Interface Builder Storyboard layout, as I can't achieve desired layout with constraints in Interface Builder alone. The iPhone 4S and iPhone 6 Plus are particularly challenging for my iOS 8 layouts. Questions: How do I find screen dimensions when the UIViewController appears? How do I detect orientation changes & resulting screen dimensions in iOS 8? How do I modify layout constraints programmatically? How do I deal with IB size classes programmatically? Maybe by "weighting" components in IB, I

I have a storyboard that contains : A "tab bar" on the left with 5 tabs A container on the right side of the tab bar that contains 6 image views that share the same space so it looks like this : Each image view is configured to occupy 1/3 of the container's width and 1/2 of its height. However, different ratios can be provided at runtime (from a JSON file) so that for example, the 1st image view's height become 70% of its container's height and 50% of its width (therefore, the 2nd and 3rd image views widths occupy 25% of the container's width and the 4th image view, 2nd line column 1 has a

I'm trying to set the layout of a view using NSLayoutConstraint s. I can set things up within the view correctly, but I also need to be able to resize the current view (the one that I'm setting the constraints for) if the constraints require it. In other words, I want to set a fixed content size with a flexible window, rather than the reverse. So basically, I have: NSDictionary *views = [NSDictionary dictionaryWithObjectsAndKeys:self.v1, @"v1", self.v2, @"v2", nil]; // Set horizontal constraints [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|-[v1]-|" options:0 metrics

I have a project with a Tab Bar, and a custom Navigation bar for each of the tabs. Each of the Navigation bar UIViews have a height constraint constant set in the storyboard. I would like to subclass this NSLayoutConstraint (for the Nav height), so that it changes the height for iPhone X. The Navigation bar needs to be much taller on an iPhone X, and since I'm not using "out of the box" objects, my constraints need to be manually set. Essentially, I want to do something like the following in the subclass, so I don't have to repeat a bunch of code and make unnecessary outlets: override func
