programmatically-created

I know how to add an IBAction to a button by dragging from the interface builder, but I want to add the action programmatically to save time and to avoid switching back and forth constantly. The solution is probably really simple, but I just can't seem to find any answers when I search it. Thank you! Nick Weaver Try this: Swift 4 myButton.addTarget(self, action: #selector(myAction), for: .touchUpInside) Objective-C [myButton addTarget:self action:@selector(myAction) forControlEvents:UIControlEventTouchUpInside]; You can find a rich source of information in Apple's Documentation. Have a look at

I have created a small demo playground to get this working before adding the view to my app. I have a scroll view that is going to contain a number of buttons to scroll through horizontally. I know that these buttons need to go into a container view within the scroll view and have created this as well. I was initially using autolayout constraints to create all of this, but have now tried using constants to ensure the content view is bigger than the scroll view. However, the buttons still will not scroll... have I missed something? Do scroll views not work with auto layout? I am doing this all

I have two scheduled tasks on my computer. They both open excel files and run a macro & are pretty similar in what they do. They both work on my computer. However I moved the scheduled tasks onto a colleagues computer. One worked the other didn't. The one that didn't worked opened excel but had an error saying: "programmatic access to visual basic project is not trusted". Like I say both excel files are very similar. The one that didn't work does reference two additional projects the other one does not. They are, Microsoft Visual Basic for Applications Extensibility 5.3 Microsoft Windows

I want to programmatically add multiple UIButtons to a view - the number of buttons is unknown at compile time. I can make one or more UIButton's like so (in a loop, but shorted for simplicity): UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchDown]; [button setTitle:@"Button x" forState:UIControlStateNormal]; button.frame = CGRectMake(100.0, 100.0, 120.0, 50.0); [view addSubview:button]; Copied/Edited from this link: How do I create a basic UIButton programmatically? But how do I

I'm trying to create a springboard-like interface within my app. I'm trying to use UIButtons added to a UIScrollView. The problem I'm running in to is with the buttons not passing any touches to the UIScrollView - if I try to flick/slide and happen to press on the button it doesn't register for the UIScrollView, but if I flick the space between buttons it will work. The buttons do click/work if I touch them. Is there a property or setting that forces the button to send the touch events up to its parent (superview)? Do the buttons need to be added to something else before being added the

I have a very long activity with a scrollview. It is a form with various fields that the user must fill in. I have a checkbox half way down my form, and when the user checks it I want to scroll to a specific part of the view. Is there any way to scroll to an EditText object (or any other view object) programmatically? Also, I know this is possible using X and Y coords but I want to avoid doing this as the form may changed from user to user. private final void focusOnView(){ your_scrollview.post(new Runnable() { @Override public void run() { your_scrollview.scrollTo(0, your_EditBox.getBottom())

First of all: thanks to @MattDowle; data.table is among the best things that ever happened to me since I started using R . Second: I am aware of many workarounds for various use cases of variable column names in data.table , including: Select / assign to data.table variables which names are stored in a character vector pass column name in data.table using variable in R Referring to data.table columns by names saved in variables passing column names to data.table programmatically Data.table meta-programming How to write a function that calls a function that calls data.table?
