Can someone let me know how to add a navigator button on top of jqChart so that when I click on that button it helps me to navigate to other page or javascript method.

By setting UIButton().menu, a menu can be shown when tapped.
And a menu is shown when long pressed, too.
I want to execute some another action (for example, change text) when tapped, and show a menu when long pressed.
How to show a menu only when long pressed, like Safari's show tabs button on the right bottom of the screen?
In Safari, tabs are shown when show tabs button is tapped, and a menu is shown when show tabs button is long pressed.
btn.showsMenuAsPrimaryAction = false
I have implemented a right item button in the navigation bar. I use the storyboard, no code. But now the back button is not displayed. What's the good way to show it again without boilerplate code ?
Thank you!
You can not see the back button on the rootViewController of the NavigationController
NavigationController automatically add the back button once you push some other ViewController to it.
It will display if you have not hides it explicitly.
If you have drag and drop the BarButtonItem as shown in the attached image, Just run the code and back button will automatically get added if it was not your RootViewController.
If it is RootViewController as displayed in images, try to push some ViewController on it, you will get the back button added.
If you add the left bar button item from Interface Builder, you will not get the back button displayed. Then you have to do it manually
I have a Bar Button Item in the navigation bar of the view (Edit Button). Unlike other buttons (UIButton), I am unable to press ctrl and drag to view controller to create a function to handle it. I want when the button is pressed, a function body to execute.
How can I link them?
Just show the assistant editor
and use the document outline (the left bar that list all your view controllers and relative items) for select the bar button item, then CTRL & drag or drag with your right mouse button:
Automatically for bar button item Xcode link as action:
Make sure the button is selected (The view should darken a bit everywhere expect where the button is) and open up the Utilities area. Open the Connections inspector in utilities (an arrow pointing to the right) and under Triggered Segues drag from the circle to your code and create your action.
I have two buttons. When I click on one button, it will go to the view controller and from that I'm navigating using a left slide menu. My issue is that if I click the other button it should also navigate through the left slide menu - but I'm able to navigate only the one view.
I have a button that has a custom view that I share between several view controllers for a rightbarbutton item on the navigationitem. Sometimes the button doesn't appear, but is clickable. This button is created programmatically (not in IB).
In one case where I pop the view controller that it is invisible on (by clicking the back button) and then push it again (by putting the button that creates it), then the button shows up again.
