在上面的代码中，我很困惑，当我在setCityName中选择一个特定的城市时，我不会去下一个视图所以请给我解决方案.....

Answer 1

而不是

    UIActionSheet *actionSheet = [[UIActionSheet alloc] init];

试试这个。

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Your Title" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];

希望它有所帮助。

Answer 2

朋友转到您的nib文件并首先将方法添加到按钮

当我在tableview＆amp;中选择索引时，我的下一个视图不会显示之后，我想进入下一个视图
