UIActionSheet与UITableView

3

我需要一些关于UIActionSheet的建议。在我的情况下，我创建了一个ActionSheet，其中我将UITableView与一些数据一起显示。

UIActionSheet *asheet = [[UIActionSheet alloc] init];
[asheet showInView:self.view]; 
[asheet setFrame:CGRectMake(0, 250, 320, 320)];


CustomView *innerView = [[CustomView alloc] initWithNibName:@"CustomView" bundle:nil];
innerView.view.frame = CGRectMake(0, 10, 320, 210);

[asheet addSubview:innerView.view];

这个CustomView包含了表格。数据正常显示，它显示了3行，现在我希望有一些类似的功能：

当我点击任何一行时，选定的行应该居中显示。
我应该把按钮（完成，取消）放在CustomView还是ActionSheet中？
当我点击“完成”按钮时，如何获取所选行？

有什么建议吗？

谢谢。

你想让你的按钮显示在表格视图还是操作表中？ - dks1725

将您的按钮作为操作表的子视图添加。 - dks1725

在按钮点击事件中如何获取所选行？ - Maulik

你需要使用flag，当你点击任何一行时，将会调用didSelectRow方法，因此在该方法中，你可以找到该行并将其分配给flag...当你按下“完成”按钮时，获取该flag的值。 - dks1725

当我点击任何一行时，所选行应该居中显示。

请提供更多关于此问题的细节，我无法正确理解。

(2)

在CustomView或ActionSheet中，我应该在哪里添加按钮（完成，取消）？

将它们添加到UIActionSheet中：

 UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:@"Title" delegate:self     cancelButtonTitle:@"Cancel Button" destructiveButtonTitle:@"Destructive Button"     otherButtonTitles:@"Other Button 1", @"Other Button 2", nil];
 popupQuery.actionSheetStyle = UIActionSheetStyleBlackOpaque;
 [popupQuery showInView:self.view];
 [popupQuery release];

(3)

当我点击“完成”按钮时，如何获取所选行？

NSIndexPath *indexPath = [MyTableView indexPathForSelectedRow]

在我的表视图中，它显示了确切的3行。如果我选择第3行，则所选行应该位于中心位置，就像2--3（已选择）---4一样。 - Maulik

@Maulik：好的，你需要查看管理行重新排序。 - Ahmad Kayyali

CustomActionSheetView.m

    }

现在你可以像下面这样从任何视图中调用所有这些内容。

例如视图.h

#import "ActionSheetDataSource.h"
#import "CustomActionSheet.h"

<CustomActionSheetDelegate>

exampleview.m

 -(void)calling
    {
        ActionSheetDataSource*dataSource=[[[ActionSheetDataSource alloc] init] autorelease];//mm
    [dataSource setTitle:@"I want to"];
    CustomButton*cBack=[CustomButton CustomButtonWithColor:[UIColor blackColor] andTitle:@"Go Back"];
   NSMutableArray *arr = [NSMutableArray arrayWithObjects:cBack ,nil];
    [dataSource setOtherButtonArr:arr];
    [CustomActionSheetView loadActionSheetInView:self.view withDataSource:dataSource andDelegate:self];

    }

    -(void)didSelectedOption:(NSString*)option
    {
     if([option isEqualToString:@"Go Back"])
        return;
     }

CustomButton.h

#导入

@interface CustomButton : UIButton
+(CustomButton*)CustomButtonWithColor:(UIColor*)color andTitle:(NSString*)title;
+(CustomButton*)CustomButtonWithColor:(UIColor*)color title:(NSString*)title andSelectedState:(BOOL)state;
@end

CustomButton.m

#import "CustomButton.h"

@implementation CustomButton

+(CustomButton*)CustomButtonWithColor:(UIColor*)color andTitle:(NSString*)title
{
CustomButton*btn=[[self class] buttonWithType:UIButtonTypeCustom];
if (btn) 
{
    [btn setTitle:title forState:UIControlStateNormal];
    [btn setTitleColor:color forState:UIControlStateNormal];
    [btn setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
}
return btn;
}

+(CustomButton*)CustomButtonWithColor:(UIColor*)color title:(NSString*)title andSelectedState:(BOOL)state
{
CustomButton*btn=[[self class] buttonWithType:UIButtonTypeCustom];
if (btn) 
{
    [btn setTitle:title forState:UIControlStateNormal];
    [btn setTitleColor:color forState:UIControlStateNormal];
    [btn setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
    [btn setSelected:state];
}
return btn;
}
@end
