There are two ways to customize a control: 1, pure code creation 2 through Xib custom controls

1. Xib Custom Controls (one xib can create multiple custom controls, but not generally)

1) First create a custom control class that inherits from the UIView Xib

• Create a custom control class that inherits from UIView

• Hold command and N to select empty in user interface to create a blank xib file

• Change the file name to be the same as the class name, drag a page of the same type as the class, and associate the class file.

• Change the size of the custom view: Select UIView to change size after size is set to freeform

• Remove battery icon: Select View to change his status bar to None

• Adding controls to Xib and associating controls to custom control classes

(Create attribute to. h file, associate event to. m file)

• Working with custom controls in. m

2) Add Xib custom Controls

• Associating a custom control class in a class that needs to add a custom control

#import "LoadingView.h"

• To create a Xib custom control

    Loadingview *lv= [ [[NSBundle Mainbundle]loadnibnamed:@ "Loadingview" owner: Self Options:Nil]Lastobject];

(Here [[nsbundle mainbundle]loadnibnamed:@ "Loadingview" owner: self options:nil] returns an array, Because you can create multiple controls at the same time in a xib, they are added sequentially to the array, but generally not .

2. Create custom controls in plain text
