iphone - 从块中呈现视图控制器不会动画

Question

我在用SVPullToRefresh

__weak InventorySearch *safeSelf = self;

[self.tableView addPullToRefreshWithActionHandler:^{
    [safeSelf refresh];   
 }];

方法 refresh 做了一些设置工作，然后调用[self presentmodalviewcontroller:controller animated:YES];

然而，视图没有动画，只是立即呈现。

Answer 1

代替

 [safeSelf refresh];

尝试这个

[safeSelf performSelectorOnMainThread:@selector(refresh) withObject:nil waitUntilDone:NO];
