有一個按鈕來激發EGORefreshTableHeaderView

Question

我使用EGOTableViewPullRefresh在tableView獲得拉動刷新效果。 我添加了一個帶有(IBAction)refreshBtnClicke的UIBarButtonItem ，它可以在EGORefreshTableHeaderView.h中調用自定義方法refreshByClickRegreshBtn:來顯示EGORefreshTableHeaderView並重新加載我的tableView

TableViewController.m

-(IBAction)refreshBtnClicked{

    [_refreshHeaderView refreshByClickRegreshBtn:self.tableView];

}

EGORefreshTableHeaderView.h

- (void)refreshByClickRegreshBtn:(UIScrollView *)scrollView{

[self setState:EGOOPullRefreshLoading];
NSLog(@"scrollView.contentInset.top :%f", scrollView.contentInset.top);// it's always 0 here
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.2];
[scrollView setContentInset:UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f)];

[UIView commitAnimations];
if ([_delegate respondsToSelector:@selector(egoRefreshTableHeaderDidTriggerRefresh:)]) {
    [_delegate egoRefreshTableHeaderDidTriggerRefresh:self];
}
}

問題 ：當tableView沒有數據時， EGORefreshTableHeaderView后，將始終顯示UIBarButtonItem 。 但是，一旦下載的數據填充到tableView ，即使調用了refreshByClickRegreshBtn: UIBarButtonItem當我再次單擊UIBarButtonItem時， EGORefreshTableHeaderView將永遠不會出現。 任何幫助表示贊賞：）

通過將[scrollView setContentInset:UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f)] [scrollView setContentOffset:CGPointMake(0, -60)]為[scrollView setContentOffset:CGPointMake(0, -60)]可以解決問題。

- (void)refreshByClickRegreshBtn:(UIScrollView *)scrollView{

[self setState:EGOOPullRefreshLoading];
NSLog(@"scrollView.contentInset.top :%f", scrollView.contentInset.top);// it's always 0 here
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.2];
//[scrollView setContentInset:UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f)];
[scrollView setContentOffset:CGPointMake(0, -60)];

[UIView commitAnimations];
if ([_delegate respondsToSelector:@selector(egoRefreshTableHeaderDidTriggerRefresh:)]) {
    [_delegate egoRefreshTableHeaderDidTriggerRefresh:self];
}
}
