Apply pull-down refresh only to IOS 6.0

A new control in iOS6.0, UIRefreshControl

Example

 

 

I saw a post posted by someone else on the forum today, saying that this control can only be used in UITableViewController. If it is used in other viewcontrollers, the following error message will be displayed during runtime: (that is, UIRefreshControl can only be managed by UITableViewController)

In fact, he ignored a point and can call it on ViewController.

- (void)addSubview:(UIView *)view;

To add UITableViewController, and then add UITableView, so that UIRefreshControl is still managed by UITableViewController, but it can still be used in other viewcontrollers. To use the native drop-down effect, do you think it is easy for us!

Example structure:

VC_view inherits from UIViewController

TV _table inherits from UITableViewController

Key code of VC_view

# Pragma mark-# pragma mark Custom Methods /****************************** **************************************** * ******* Function Name: -(void) refreshData Function Description: refresh View data input parameter: N/A output parameter: N/A return parameter: N/A remarks: **************************************** **************************************/- (void) refreshData {self. pTV_table = [[TV _table alloc] initWithNibName: @ "TV _table" bundle: nil]; self. pTV_table.view.frame = CGRectMake (0, 0,320,416); [_ pV_main addSubview: _ pTV_table.tableView];}

Global variables must be declared when you add another Controller Or View to UIViewController.

// When UITableViewController is introduced, its global variables must be declared in the Controller to be introduced and cannot be declared as local variables. @ Property (strong, nonatomic) TV _table * pTV_table;

This is a feature of ARC.

Key code of TV _table
