Swift settings navigation left and right side buttons

Let's take the right button for example, the left method is similar

Method One, direct custom text

1. Let Item=uibarbuttonitem (title: "Share", Style:uibarbuttonitemstyle. Plain, target: Self , action: nil)
2. Self. Navigationitem. Rightbarbuttonitem=item

Method Two, use the System icon

1. Let item1=uibarbuttonitem (Barbuttonsystemitem:uibarbuttonsystemitem. Done, target: Self , action: nil)//The icon used here Uibarbuttonsystemitem is an enumeration. You can try out what the other values are.
2. Self. Navigationitem. Rightbarbuttonitem=item1

Method Three, using a custom control

Here we customize the button as an example to implement

1. let btn1=uibutton (frame:  CGRectMake (0, 0, 5< Span class= "Xcodenumber" >0, 30))   
2. btn1 . Settitle ( forstate: uicontrolstate
3. let item 2=uibarbuttonitem (Customview: btn1)   
4. self.navigationitem.rightbarbuttonitem=item2&NBSP;&NBSP;

Method Four, we can also directly put a picture up

1. var img=uiimage (named: "test_img")
3. Let item3=uibarbuttonitem (image:img, style:uibarbuttonitemstyle. Plain, target: Self , action: nil)
4. Self. Navigationitem. Rightbarbuttonitem=item3

If we just follow the above method, we will find out is a solid color picture, is because the iOS flat design style application to make such a, if you need a real picture, we can set a img=img? Imagewithrenderingmode (uiimagerenderingmode.alwaysoriginal)

The above method is to add a button

What do I do if I want to add more than one time?

We found that the way we assign values to the right button is that Rightbarbuttonitem actually has properties Rightbarbuttonitems

Look at the code

1. let items1=uibarbuttonitem ( Barbuttonsystemitem: uibarbuttonsystemitem target: self, action: nil)   
2. Let items2=uibarbuttonitem (Barbuttonsystemitem: uibarbuttonsystemitem  target: self, action: nil)   
3. self.navigationitem1,items2]&NBSP;&NBSP;

If you want to set the left button directly call Self.navgigationItem.leftBarButtonItem can
