我有一个要求我在哪里显示actionSheet但是如果用户没有通过选择其中一个选项来关闭此操作表,我想通过程序在特定事件上自动关闭它.任何想法的人,我怎么能逐步解雇这个动作表？

我已阅读另一篇文章(如何解散行动表),我可以使用

[actionSheet dismissWithClickedButtonIndex:0 animated:YES];

使用关闭按钮关闭uiactionsheet,如下所述:

                                                otherButtonTitles:nil];

[actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerView.showsSelectionIndicator = YES;
pickerView.dataSource = self;
pickerView.delegate = self;


[actionSheet addSubview:pickerView];
[pickerView release];

UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:@"Close"]];
closeButton.momentary = YES; 
closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);
closeButton.segmentedControlStyle = UISegmentedControlStyleBar;
closeButton.tintColor = [UIColor blackColor];
[closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];
[actionSheet addSubview:closeButton];


[actionSheet dismissWithClickedButtonIndex:0 animated:YES];


[closeButton release];
