我需要在https://github.com/gmoledina/GMGridView GMGridView 中添加拉动刷新效果！所以我只是在我的视图控制器中将 GMGridView 与 EGOTableViewPullRefresh 集成，但事实证明没有新鲜效果，并且当我拉出 refreshHeaderView 时不显示向上箭头。以下是我的 viewController 中的一些代码片段：
- (void)loadView
{
[super loadView];
self.view.backgroundColor = [UIColor whiteColor];
NSInteger spacing = INTERFACE_IS_PHONE ? 5 : 15;
GMGridView *gmGridView = [[GMGridView alloc] initWithFrame:self.view.bounds];
gmGridView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
gmGridView.backgroundColor = [UIColor clearColor];
[self.view addSubview:gmGridView];
_gmGridView = gmGridView;
_gmGridView.style = GMGridViewStyleSwap;
_gmGridView.itemSpacing = spacing;
_gmGridView.minEdgeInsets = UIEdgeInsetsMake(spacing, spacing, spacing, spacing);
_gmGridView.centerGrid = YES;
_gmGridView.actionDelegate = self;
_gmGridView.sortingDelegate = self;
_gmGridView.transformDelegate = self;
_gmGridView.dataSource = self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
if (_refreshHeaderView == nil) {
EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.gmGridView.bounds.size.height, self.view.frame.size.width, self.gmGridView.bounds.size.height)];
view.delegate = self;
[self.gmGridView addSubview:view];
_refreshHeaderView = view;
[view release];
}
[_refreshHeaderView refreshLastUpdatedDate];
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
[_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
[_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];
}
- (void)reloadTableViewDataSource{
// should be calling your tableviews data source model to reload
// put here just for demo
_reloading = YES;
}
- (void)doneLoadingTableViewData{
_reloading = NO;
[_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.gmGridView];
}
- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{
NSLog(@"egoRefreshTableHeaderDidTriggerRefresh");
[self reloadTableViewDataSource];
[self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0];
}
- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{
NSLog(@"egoRefreshTableHeaderDataSourceIsLoading");
return _reloading; // should return if data source model is reloading
}
- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{
return [NSDate date]; // should return date data source was last changed
}
