UIRefreshControl的使用

注意：

一、须要在ios6.0以后的版本中使用

二、UIRefreshControl目前只能用于UITableViewController，若是用在其余ViewController中，运行时会错误（即UIRefreshControl只能被UITableViewController管理）

 

UIRefreshControl类以下所示,东西很少

NS_CLASS_AVAILABLE_IOS(6_0) @interface UIRefreshControl : UIControl

/* The designated initializer
 * This initializes a UIRefreshControl with a default height and width.
 * Once assigned to a UITableViewController, the frame of the control is managed automatically.
 * When a user has pulled-to-refresh, the UIRefreshControl fires its UIControlEventValueChanged event.
 */
- (id)init;

@property (nonatomic, readonly, getter=isRefreshing) BOOL refreshing;

@property (nonatomic, retain) UIColor *tintColor UI_APPEARANCE_SELECTOR;
@property (nonatomic, retain) NSAttributedString *attributedTitle UI_APPEARANCE_SELECTOR;

// May be used to indicate to the refreshControl that an external event has initiated the refresh action
- (void)beginRefreshing NS_AVAILABLE_IOS(6_0);
// Must be explicitly called when the refreshing has completed
- (void)endRefreshing NS_AVAILABLE_IOS(6_0);

@end
