添加一个新的视图的视图控制器 - iOS设备

问题描述：

我工作的一个应用程序，在那里当我按下菜单键，IBAction为创建一个具有覆盖（添加子视图）。这个子视图必须保存必须可访问的按钮。我最初通过添加额外的按钮到以前的观点犯了一个错误。因此，当我按下菜单按钮的新的覆盖弹出与没有被访问的额外的按钮。有什么建议吗？我是iOS编程的新手。谢谢添加一个新的视图的视图控制器 - iOS设备

- (IBAction) btnMoveTo:(id)sender 
{ 
UIButton* button= (UIButton*)sender; 

[self overlayCheck]; 

[movingButton setHidden:false]; 
[movingButton2 setHidden:false]; 
[movingButton3 setHidden:false]; 


[movingButton moveTo: 
CGPointMake(125,250) duration:0.8 
       option:curveValues[selectedCurveIndex]]; 

[movingButton2 moveTo: 
CGPointMake(25,250) duration:0.8 
       option:curveValues[selectedCurveIndex]]; 

[movingButton3 moveTo: 
CGPointMake(225,250) duration:0.8 
       option:curveValues[selectedCurveIndex]]; 

} 


-(void)overlayCheck{ 

CGRect frame = [homeButton frame]; 
UIView* view = [[UIView alloc] initWithFrame:CGRectMake(frame.origin.x - FrameSizeIncreaseAmount, frame.origin.y - FrameSizeIncreaseAmount, frame.size.width + FrameSizeIncreaseAmount * 2, frame.size.height + FrameSizeIncreaseAmount * 2)]; 
view.backgroundColor = [UIColor blackColor]; 


[self.view addSubview:view]; 


[UIView beginAnimations:@"fade in" context:nil]; 
[UIView setAnimationDuration:0.2]; 

[view setBackgroundColor:[[UIColor grayColor] colorWithAlphaComponent:MaxAlpha]]; 
[UIView commitAnimations]; 


}

moveButton，movingButton2和movingButton3应该在新视图上。覆盖层不允许我访问按钮。

你能告诉我们一些代码吗？ – Aymarick 2012-07-10 09:51:04

这可能是因为你还没有联系的按钮到'IBAction'方法被后推调用。 – geminiCoder 2012-07-10 10:09:11

答

不知道如果我理解正确，但你应该添加按钮，您的覆盖查看您在overlayCheck方法创建：

-(void)overlayCheck 
{ 
    CGRect frame = [homeButton frame]; 
    UIView* view = [[UIView alloc] initWithFrame:CGRectMake(frame.origin.x - FrameSizeIncreaseAmount, frame.origin.y - FrameSizeIncreaseAmount, frame.size.width + FrameSizeIncreaseAmount * 2, frame.size.height + FrameSizeIncreaseAmount * 2)]; 
    view.backgroundColor = [UIColor blackColor]; 

    // --------------------------------------------- 
    // Becareful how you set the frame X-Y coordinate 
    // for your button if your moving buttons uses 
    // initWithFame:CGRectMake(X,Y,Width,Height); 
    // 
    // The X,Y are relative to the parent view 
    // that you add the moving buttons to 
    // --------------------------------------------- 
    [view addSubview:movingButton1]; 
    [view addSubview:movingButton2]; 
    [view addSubview:movingButton3]; 

    [self.view addSubview:view]; 


    [UIView beginAnimations:@"fade in" context:nil]; 
    [UIView setAnimationDuration:0.2]; 

    [view setBackgroundColor:[[UIColor grayColor] colorWithAlphaComponent:MaxAlpha]]; 
    [UIView commitAnimations]; 
}
