Use of the Objective-c:uitoolbar control

Uitoolbar control: is a frequently used toolbar control, in which you can add many other controls, UILabel, UIButton, UIImage, Uibarbuttonitem, Uitextfield, and so on 、、。 A layout that can be used to customize the controls in view views. After the layout of the view is complete, it can be used directly, without the code to control the coordinates and size of the control, convenient and accurate.

First, using the system default. xib files in the Uitoolbar made add and remove strips (delete and add pictures)

(1) Add the Uitoolbar of the system setting with two labels label

　　The code is as follows: You need to manually set the frame specific coordinates x, y, size width,height for the added control in your code

Second, using the pre-custom layout of the. xib file in the Uitoolbar made additions and deletions (delete and add pictures)

(2) Custom uitoolbar after adding UIImage, Uilabel controls

　　　　

The code is as follows: You do not need to set the frame for the added control in your code, it is already laid out in the. xib file.
