header刷新不回弹的问题 #1292
Description
1.header刷新不回弹的问题
复现代码：[table.mj_header beginRefreshing];
[table.mj_footer endRefreshing];
一起使用就会毕现，当然一般人不会这么用，只是举个例子说明问题
MJRefreshHeader中setState方法
`- (void)setState:(MJRefreshState)state
{
MJRefreshCheckState
// 根据状态做事情
if (state == MJRefreshStateIdle) {
NSLog(@"2");
if (oldState != MJRefreshStateRefreshing) return;
// 保存刷新时间
[[NSUserDefaults standardUserDefaults] setObject:[NSDate date] forKey:self.lastUpdatedTimeKey];
[[NSUserDefaults standardUserDefaults] synchronize];
// 恢复inset和offset
[UIView animateWithDuration:MJRefreshSlowAnimationDuration animations:^{
self.scrollView.mj_insetT += self.insetTDelta;
// 自动调整透明度
if (self.isAutomaticallyChangeAlpha) self.alpha = 0.0;
} completion:^(BOOL finished) {
self.pullingPercent = 0.0;
if (self.endRefreshingCompletionBlock) {
self.endRefreshingCompletionBlock();
}
}];
} else if (state == MJRefreshStateRefreshing) {
MJRefreshDispatchAsyncOnMainQueue({
NSLog(@"1");
[UIView animateWithDuration:MJRefreshFastAnimationDuration animations:^{
if (self.scrollView.panGestureRecognizer.state != UIGestureRecognizerStateCancelled) {
CGFloat top = self.scrollViewOriginalInset.top + self.mj_h;
// 增加滚动区域top
self.scrollView.mj_insetT = top;
// 设置滚动位置
CGPoint offset = self.scrollView.contentOffset;
offset.y = -top;
[self.scrollView setContentOffset:offset animated:NO];
}
} completion:^(BOOL finished) {
[self executeRefreshingCallback];
}];
})
}
}`
打印结果：2，1
从代码中也可以发现state == MJRefreshStateRefreshing时加了这一句MJRefreshDispatchAsyncOnMainQueue
