如何实现类似的菜单视图？ [iOS]

有没有办法使用 sdk 轻松实现此菜单，还是必须手动制作（将覆盖视图和其他视图与按钮结合起来）？

这是标准 UIKit 框架中的 UIActionSheet 类

来自 Apple 的 UIActionSheet 文档由我进行了一些扩展，以触发呼叫操作。

在此处输入图像描述
ViewController 全局范围内的 Delcare：
UIActionSheet * actionSheet; 和 UIView * yourView;

Int the viewDidLoad：

actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                             delegate:self
                             cancelButtonTitle:@"Cancel"
                             destructiveButtonTitle:@"Delete Note"
                             otherButtonTitles:@"Call",@"Add a Contact",nil];

[yourView = self.view]

要通过某个带有 IBAction 声明的按钮来触发菜单，您将需要：

-(IBAction)viewMapButton:(id) sender
{
    [actionSheet showInView:yourView];

}

根据用户选择采取适当的操作声明以下方法并检查 [actionSheet buttonTitleAtIndex:buttonIndex] 等于什么：

- (void)actionSheet:(UIActionSheet *)actionSheet
        clickedButtonAtIndex:(NSInteger)buttonIndex
        {
        NSString * what_action = [actionSheet buttonTitleAtIndex:buttonIndex];
        NSLog(@"The %@ button was tapped.", what_action);
             if ([what_action isEqualToString:@"Call"])
                 {
                 NSString *phoneNumber = [[NSString alloc] 
                        initWithString:@"telprompt:1234567890"];
                 [[UIApplication sharedApplication] 
                        openURL:[NSURL URLWithString:phoneNumber]];
                 }
}

[注意：调用的触发在 iOS 模拟器上不起作用]

Easy example from Apple's documentation of UIActionSheet extended a bit by me to fire call action.

enter image description here
Delcare in the global scope of the ViewController:
UIActionSheet * actionSheet; and UIView * yourView;

Int the viewDidLoad:

actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                             delegate:self
                             cancelButtonTitle:@"Cancel"
                             destructiveButtonTitle:@"Delete Note"
                             otherButtonTitles:@"Call",@"Add a Contact",nil];

[yourView = self.view]

To fire the menu by some declared button with IBAction you will need:

-(IBAction)viewMapButton:(id) sender
{
    [actionSheet showInView:yourView];

}

To take appropriate action depending on user choice declare following method and check what [actionSheet buttonTitleAtIndex:buttonIndex] was equal to:

- (void)actionSheet:(UIActionSheet *)actionSheet
        clickedButtonAtIndex:(NSInteger)buttonIndex
        {
        NSString * what_action = [actionSheet buttonTitleAtIndex:buttonIndex];
        NSLog(@"The %@ button was tapped.", what_action);
             if ([what_action isEqualToString:@"Call"])
                 {
                 NSString *phoneNumber = [[NSString alloc] 
                        initWithString:@"telprompt:1234567890"];
                 [[UIApplication sharedApplication] 
                        openURL:[NSURL URLWithString:phoneNumber]];
                 }
}

[NOTE: Firing of call does not work on iOS Simulator]
