actionSheet imageView的边界

需要在actionsheet修改imageView的边界属性:

<!-- language: lang-c -->

        #pragma UIActionSheetDelegate Methods
        - (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
           /*[[[actionSheet valueForKey:@"_buttons"] objectAtIndex:0] imageView].frame = CGRectMake(0, 0, 25.0f, 25.0f);*/

           [[[actionSheet valueForKey:@"_buttons"] objectAtIndex:0] imageView].bounds = CGRectMake(0, 0, 25.0f, 25.0f);

           /*UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 25.0f, 25.0f)];
           imgView.image = [UIImage imageNamed:@"symbol-pin.png"];
           [[actionSheet superview] addSubview:imgView];*/ 
    }

然后在编码之后什么也出现:

[[[actionSheet valueForKey:@"_buttons"] objectAtIndex:0] imageView].bounds = CGRectMake(0, 0, 25.0f, 25.0f);

创建actionsheet的代码:

<!-- language: lang-c -->

    - (IBAction)showModeOptions:(id)sender {
       if (!modeOptions) {
         modeOptions = [[UIActionSheet alloc]initWithTitle:@"" delegate:self cancelButtonTitle:@"Abbrechen" destructiveButtonTitle:nil otherButtonTitles:@"Pin",@"Linie", @"Polygon", nil];

          [[[modeOptions valueForKey:@"_buttons"] objectAtIndex:0] setImage:[UIImage imageNamed:@"symbol-pin.png"] forState:UIControlStateNormal];

          [[[modeOptions valueForKey:@"_buttons"] objectAtIndex:1] setImage:[UIImage imageNamed:@"symbol-line.png"] forState:UIControlStateNormal];

          [[[modeOptions valueForKey:@"_buttons"] objectAtIndex:2] setImage:[UIImage imageNamed:@"symbol-polygon.png"] forState:UIControlStateNormal];

          modeOptions.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
      }
      [modeOptions showFromTabBar:self.tabBarController.tabBar]; 
}

图片是88*88px的,我需要图片像imageView是25*25px的边框。不知道应该怎么实现?

    -(void)actionSheetClicked
    {
    
    if(!self.modeOptions)
        {
            UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Dummy",nil]; //Here I add dummy button for getting cancel button style.
            self.modeOptions = actionSheet;
            [actionSheet release];
        }
        self.modeOptions.actionSheetStyle = UIActionSheetStyleBlackOpaque;
    
    
        [self.modeOptions showFromTabBar:self.tabBarController.tabBar];//Here i show from tab bar, you can showfromview also
    //    [self.modeOptions setBounds:CGRectMake(0, 0, 320, 300)];
        UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
        if (orientation == UIInterfaceOrientationPortrait ||
            orientation == UIInterfaceOrientationPortraitUpsideDown)//frame size for action sheet in both modes
        {
            [self.modeOptions setBounds:CGRectMake(0, 0, 320, 300)];
    
        }
        else
        {
            [self.modeOptions setBounds:CGRectMake(0, 0, 480,250)];
        }
        UIButton *buttonDum = (UIButton *)[[self.modeOptions subviews] objectAtIndex:0];
    
        [buttonDum setHidden:YES];//hide dummy button..
    
        UIButton *cancelButton = (UIButton *)[[self.modeOptions subviews] objectAtIndex:1];
    
        if( !self.button1)
        {
    
            UIButton *Btn = [[UIButton alloc]initWithFrame:CGRectMake(80, 40, 70, 70)];//**Here I use 70 X 70 px image , you can edit it**
            self.button1 = Btn;
            [self.button1 addTarget:self action:@selector(invokeFirstBtn) forControlEvents:UIControlEventTouchUpInside];
            [self.button1 setImage:[UIImage imageNamed:@"btn1Image.png"] forState:UIControlStateNormal];
            [self.modeOptions addSubview:self.button1];
            [Btn release];
        }
        if( !self.button2)
        {
            UIButton *Btn = [[UIButton alloc]initWithFrame:CGRectMake(180, 40, 70, 70)];//**Here I use 70 X 70 px image , you can edit it**
            self.button2 = sharBtn;
            [self.button2 addTarget:self action:@selector(invokeButton2) forControlEvents:UIControlEventTouchUpInside];
            [self.button2 setImage:[UIImage imageNamed:@"btn2Image.png"] forState:UIControlStateNormal];
            [self.modeOptions addSubview:self.button2];
            [Btn release];
        }
        if (orientation == UIInterfaceOrientationPortrait ||
            orientation == UIInterfaceOrientationPortraitUpsideDown)//frame size for action sheet in both modes
        {
            cancelButton.frame = CGRectMake(50, 140, 220, 40);
            self.button1.frame = CGRectMake(65, 40, 70, 70);
            self.button2.frame = CGRectMake(175, 40, 70, 70);
        }
        else
        {
            cancelButton.frame = CGRectMake(135, 140, 220, 40);
            self.button1.frame = CGRectMake(155, 40, 70, 70);
            self.button2.frame = CGRectMake(260, 40, 70, 70);
        }
    }
    

    用这段代码,可以随意修改框架尺寸,还可以创建不带虚拟按钮的actionsheet。
