弹出子视图

Question

如何仅动画框架即。子视图，而不是整个视图，以及如何在该子视图内添加分段控制按钮？当我点击一个按钮时，我希望子视图弹出，但子视图应该是半透明的，以便后面的父视图可见。

Answer 1

采取的UIView全球，如果你想添加和删除，这也添加子视图中您的观点

 UIView *tempView=[[UIView alloc]initWithFrame:sel.view.frame]; 
     /////== Add your subviews in this tempView 
     tempView.transform = CGAffineTransformMakeScale(1.3, 1.3); 
     tempView.alpha = 0; 
     [UIView animateWithDuration:.35 animations:^{ 
      tempView.alpha = 0.94; 
      tempView.transform = CGAffineTransformMakeScale(1, 1); 
     }]; 
     tempView.frame=CGRectMake(0, 0, 320, 480); 
     [self.view addSubview:tempView]; 

更新：在您的.h文件中的UIView

先来的物体，像

UIView *tempView; 
BOOL isOpen; 

在 viewWillDidLoad:方法

只是定义了这个

isOpen = NO; 

和使用这个代码后

-(IBAction)btnSetting_Clicked:(id)sender 
{ 
    if (isOpen) { 
     isOpen = NO; 
     [tempView removeFromSuperview]; 
    } 
    else { 
     isOpen = YES; 
     tempView=[[UIView alloc]initWithFrame:self.view.frame]; 
     /////== Add your subviews in this tempView 
     [tempView addSubview:yourSegControl]; 
     tempView.transform = CGAffineTransformMakeScale(1.3, 1.3); 
     tempView.alpha = 0; 
     [UIView animateWithDuration:.35 animations:^{ 
      tempView.alpha = 0.94; 
      tempView.transform = CGAffineTransformMakeScale(1, 1); 
     }]; 
     tempView.frame=CGRectMake(0, 0, 320, 480); 
     [self.view addSubview:tempView]; 

    } 
} 

我希望这可以帮到你..

您可以添加子视图主要查看

CGRect frame = CGRectMake(x, y, width, height); // Replacing with your dimensions 
UIView *subView = [[UIView alloc] initWithFrame:frame]; 
[self.view addSubview:subView]; 

可以透明使用它

[subView setAlpha:0.2]; 

您可以添加任何UI控件这一观点做。

希望这会帮助你。

首先你要YOUE subview透明：

[subview setAlpha:0.5f]; 

然后是addSubView行之前添加以下代码：

CATransition *animation = [CATransition animation]; 
[animation setType:kCATransitionMoveIn];   // you can try carious options here 
[animation setSubtype:kCATransitionFromRight]; // here too 
[animation setDuration:0.3]; 
[animation setValue:@"Throb" forKey:@"MyAnimationType"]; 
[subview.layer addAnimation:animation forKey:nil];
