如何实现类似的菜单视图？ [iOS的]

Question

有没有办法用sdk轻松实现这个菜单，还是我必须手动制作（将叠加视图和其他视图与按钮组合在一起）？

提前致谢！

Answer 1

这是来自标准UIKit框架的UIActionSheet类

Answer 2

来自UIActionSheet的{​​{3}}的简单示例让我有点扩展来解除呼叫操作。

DelCon在ViewController的全球范围内：  UIActionSheet * actionSheet;和UIView * yourView;

在viewDidLoad中：

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

[yourView = self.view]

要通过IBAction的某个声明按钮触发菜单，您需要：

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

}

根据用户选择采取适当的行动，声明以下方法并检查[actionSheet buttonTitleAtIndex:buttonIndex]等于：

- (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]];
                 }
}
