如何在UIActionSheet中显示自定义视图?
我有一个带有日期选择器的 UIView,我想将其显示在操作表中。我使用以下代码:
-(IBAction) button_click:(id)sender{
//UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"the title" delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Destructive" otherButtonTitles:@"other", nil];
UIActionSheet *sheet = [[UIActionSheet alloc] init];
ActionSheetController *actionSheet = [[ActionSheetController alloc] initWithNibName:@"ActionSheetView" bundle:nil];
[sheet addSubview:actionSheet.view];
[sheet showInView:self.view];
}
我得到的是从底部出现的新视图的顶部部分,仅此而已。如果我注释中间的两行代码并取消注释顶部部分以显示常规操作表,则它可以正常工作。有什么想法我可能做错了什么吗?
I have a UIView with a date picker that I'd like to display in an action sheet. I'm using the following code:
-(IBAction) button_click:(id)sender{
//UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"the title" delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Destructive" otherButtonTitles:@"other", nil];
UIActionSheet *sheet = [[UIActionSheet alloc] init];
ActionSheetController *actionSheet = [[ActionSheetController alloc] initWithNibName:@"ActionSheetView" bundle:nil];
[sheet addSubview:actionSheet.view];
[sheet showInView:self.view];
}
What I get is a little bit of the top part of the new view coming up from the bottom and that's it. If I comment the two middle lines of code and uncomment the top part to display a regular action sheet, it works fine. Any ideas what I might be doing wrong?

我不相信您可以在 UIActionSheet 中指定自定义视图。我的理解是你只能显示一个标题和1个或多个按钮。下面是Apple文档中对UIActionSheet的描述:
UIActionSheet 类参考
I do not believe you can specify Custom Views in a UIActionSheet. My understanding is that you can only display a title and 1 or more buttons. Below is the description of UIActionSheet in the Apple documentation:
UIActionSheet Class Reference
我发现发生这种行为是因为我没有正确使用 UIActionSheet 构造函数。应包含按钮和标题:
I've discovered the behavoir occurs because I haven't used the UIActionSheet constructor properly. The buttons and title should be included:
您可能想查看我制作的 UIActionSheet 替代方案,它可以让您显示自定义内容视图,而无需任何肮脏的黑客: https:// github.com/JonasGessner/JGActionSheet 与 UIActionSheet 相比,它还有一些其他优点!
You might want to check out an UIActionSheet alternative I made which lets you display custom content views without any dirty hacks: https://github.com/JonasGessner/JGActionSheet It has some other advantages over UIActionSheet as well!
使用 UIActionSheetDelegate,之后您可以使用此委托将图像添加到警报表的按钮
use UIActionSheetDelegate and after that you can with this delegate add for example a image to button of alertsheet
