ios6新特性之下拉刷新UIRefreshControl
ios6官方提供了下拉刷新的功能，水滴状，下面是它的一些用法
1.用UITableViewController
#import <UIKit/UIKit.h>
@interface RefreshViewController : UITableViewController
@end
- (void)viewDidLoad
{
[super viewDidLoad];
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
refreshControl.tintColor = [UIColor blackColor];
refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:@"刷新"];
[refreshControl addTarget:self action:@selector(refreshView:) forControlEvents:UIControlEventValueChanged];
self.refreshControl = refreshControl;
}
- (void)refreshView:(UIRefreshControl*)refreshControl
{
if (refreshControl.refreshing)
{
refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:@"refreshing..."];
[self performSelector:@selector(loadData)];
}
}
- (void)loadData
{
//load data
[self.refreshControl endRefreshing];
[self.tableView reloadData];
}
2.UIRefreshView + UITableView
@interface DefaultTableView : UITableView
@end
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
UIRefreshControl *refreshView = [[UIRefreshControl alloc] init];
refreshView.attributedTitle = [[NSAttributedString alloc] initWithString:@"下拉刷新"];
[refreshView addTarget:self action:@selector(refreshView:) forControlEvents:UIControlEventValueChanged];
[self addSubview:refreshView];
}
return self;
}
- (void)refreshView:(UIRefreshControl*)refreshView
{
if (refreshView.refreshing)
{
refreshView.attributedTitle = [[NSAttributedString alloc] initWithString:@"loading..."];
[self performSelector:@selector(loadDataForTableView:) withObject:refreshView];
}
}
- (void)loadDataForTableView:(UIRefreshControl*)refreshView
{
//load data
}
