Refresh Dome and iosdome from the pull and load drop-down lists on ios

A small pull-up load of more pull-down and refresh small Dome is written for the trainer.

There is not much technical content, but it is just used as an inspiration for new users. Is the extension of the last drop-down load. It is much easier to look at it first.

Dome download: http://download.csdn.net/detail/u010123208/8062715

Let's take a look:

The pull-up home is a view on the bottom after the pull-up, which is used to prompt the user to pull up and load more. If the user pulls up, the event is triggered, load and give a prompt in the attempt. At the same time, load the data in the background, add the added data to the data array, and then re-import the list;

The same operation is to clear the array and re-import the data;

First, we need to create two views. One is the top display and the other is the bottom display;

Display the current text, an image, and an activity indicator box in the view (hidden when network requests load data ), if you do not understand how to download the Dome file, you can see it.

Typedef enum {InsertStateNomal, // InsertStateDrapUp, // InsertStateDrapUp, // InsertStateDrapDown, // InsertStateRun, // loading status} InsertState; @ interface HeadView: UIView @ property (nonatomic, strong) UIImageView * imageView; @ property (nonatomic, strong) UILabel * label; @ property (nonatomic, assign) InsertState insertState; @ property (nonatomic, strong) optional * activity;-(void) setInsertNomal;-(void) setInsertDrapDown;-(void) setInsertRun; @ end @ interface FootView: UIView @ property (nonatomic, strong) UIImageView * imageView; @ property (nonatomic, strong) UILabel * label; @ property (nonatomic, assign) InsertState insertState; @ property (nonatomic, strong) UIActivityIndicatorView * activity;-(void) setInsertNomal; -(void) setInsertDrapDoUp;-(void) setInsertRun; @ end

Enumeration is used to indicate the current status of the view;

In fact, the content of both views is exactly the same;

Finally, the list is displayed;

Note the following:

• How to add a view to a table
• The added bottom view is constantly changing as the content increases (here I use KVO to control the position after the array element changes)
• How to control the short view display when the pull-down or pull-up is complete
• UIScrollview proxy condition;

How to add a network switch in the iPhone 5C (ios7) drop-down menu, like android

Is it about switching the cellular mobile network?
You cannot add it yourself without jailbreak. Check if the custom control center can be updated after Apple.
All settings for the pull-up and drop-down menus are in the notification center and control center.
Hope to help you

Can I use the pull-up and drop-down menus on the screen lock page of The ios71 system? If there is any information, do not view the black screen and then press the information to slide and unlock

Of course ~
