Question

似乎UIActionController的呈现似乎以某种方式调用我的搜索栏文本字段textDidBeginEditing方法。最初在搜索栏已经辞职的第一响应者之后呈现控制器。这是UIActionController的预期行为吗？它是否意味着一旦被解雇后重新激活以前活动的搜索栏？

任何帮助都会很棒！

编辑：

我在搜索栏上设置了一个断点didBeginEditing方法，然后做了一个回溯试图看看谁在调用方法开始（不确定这是否是正确的方法）。这就是我得到的......这对任何想法都有帮助吗？

[[NSOperationQueue mainQueue]addOperationWithBlock:^{
    [self presentViewController:alert animated:YES completion:nil];
}];
