ios 界面和类映射

1、新建view,在View 中添加控件，并且为各个控件设置不同的tag值。

2、新建对应的Object c 对象

-(id)initWithCoder:(NSCoder *)aDecoder{
    self=[super initWithCoder:aDecoder];
    if (self) {
        [self initView];
    }
    return self;
}

-(void)createPopSearchView{
    NSArray * popSearchViews=[[NSBundle mainBundle] loadNibNamed:@"UIPopSearchView" owner:self options:nil];
//UIPopSearchView 为自定义的xib文件名称。
    self.popSearchView=[popSearchViews objectAtIndex:0];
    if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPad){
    self.popSearchView.frame=CGRectMake(self.mapView.frame.size.width/2-self.popSearchView.frame.size.width/2, self.mapView.frame.size.height/2-self.popSearchView.frame.size.height/2, self.popSearchView.frame.size.width, self.popSearchView.frame.size.height);
    }else{
    self.popSearchView.frame=CGRectMake(15, 25, self.popSearchView.frame.size.width, self.popSearchView.frame.size.height);
    }
    
    self.popSearchView.listener=self;
}

 3、创建View对象，并初始化。

-(void)initView{
    //从布局文件中引用对应的插件。
    self.backgroundColor=[UIColor whiteColor];
    [[self layer] setCornerRadius:5];
    [[self layer] setBorderWidth:2];
    [[self layer] setBorderColor:[UIColor blackColor].CGColor];
    self.popSearchTitle=(UILabel*)[self viewWithTag:1];
    self.popSearchClose=(UIButton*)[self viewWithTag:2];
    self.popSearchInput=(UISearchBar*)[self viewWithTag:3];
    //去掉searchbar 的边框。
    self.popSearchInput.backgroundColor=[UIColor clearColor];
    for (UIView *subView in self.popSearchInput.subviews) {
        if([subView isKindOfClass:NSClassFromString(@"UISearchBarBackground")]){
            [subView removeFromSuperview];
        }
    }
    self.popSearchSearch=(UIButton*)[self viewWithTag:4];
    self.popSearchSlider=(UISlider*)[self viewWithTag:5];
    self.popSearchSlider.value=0.5;
    self.popSearchRim=(UILabel*)[self viewWithTag:6];
  
    
    [self.popSearchClose addTarget:self action:@selector(dismiss) forControlEvents:UIControlEventTouchUpInside];
    
    [self.popSearchSearch addTarget:self action:@selector(search) forControlEvents:UIControlEventTouchUpInside];
    
    [self.popSearchSlider addTarget:self action:@selector(onSliderTouch) forControlEvents:UIControlEventValueChanged];
}
