Question

亲爱的，我是Objective-j / c的新手，而卡布奇诺并不确定这一切是如何融合在一起的。

以下代码取自http://github.com/jfahrenkrug/CappuccinoLocations1 我需要做的是：

我需要一个登陆主菜单，它是一个CPView，名为MainView，带有五个左右的按钮，当你单击MainView上的LocationButton时，用LocationView替换MainView，它显示了jfahrenkrug工作的内容。每个其他按钮都会发生类似的效果。

处理这种方法的正确Objective-c / j方法是什么？

@import <Foundation/CPObject.j>
@import "src/Location/LocationView.j"

@implementation AppController : CPObject
{
  LocationView locationView;
}

- (void)applicationDidFinishLaunching:(CPNotification)aNotification
{
    var theWindow = [[CPWindow alloc] initWithContentRect:CGRectMakeZero()          styleMask:CPBorderlessBridgeWindowMask],
      mainContentView = [theWindow locationView],
      bounds = [locationView bounds];


[mainContentView setBackgroundColor:[CPColor colorWithRed:212.0 /255.0 green:221.0/ 255.0 blue:230.0/255.0 alpha:1.0]];

locationView = [[LocationView alloc]    initWithFrame:CGRectMake(0,0,920.0,590.0)];
[locationView setCenter:[mainContentView center]];
[locationView setBackgroundColor:[CPColor whiteColor]]
[locationView setAutoresizingMask:CPViewMinXMargin | CPViewMaxXMargin |     CPViewMinYMargin | CPViewMaxYMargin];

var shadow = [[CPShadowView alloc] initWithFrame:CGRectMakeZero()];
[shadow setFrameForContentFrame:[locationView frame]];
[shadow setAutoresizingMask:CPViewMinXMargin | CPViewMaxXMargin | CPViewMinYMargin | CPViewMaxYMargin];
[mainContentView addSubview:shadow];
[mainContentView addSubview:locationView];

[theWindow orderFront:self];

}

现在我们有了locationView.j

@import "LocationsController.j"
@import "LocationListView.j"
@import "MapController.j"
@import "LocationsToolbar.j"
@import "LocationDetailView.j"
@import "LocationDetailController.j"

@implementation LocationView : CPView
{
  LocationsController locationsController;
  LocationListView locationListView;
  MapController mapController;
  MKMapView mapView;
  CPTextField coordinatesLabel;
  LocationsToolbar locationsToolbar;
  LocationDetailView locationDetailView;
  LocationDetailController locationDetailController;
  CPTextField searchField;

  //  id delegate @accessors;
}

- (id)initWithFrame:(CGRect)aFrame
{
  self = [super initWithFrame:aFrame];
  if(self){

    locationsController = [[LocationsController alloc] init];
    [locationsController loadExampleLocations];

    locationListView = [[LocationListView alloc]    initWithFrame:CGRectMake(0.0,0.0,226.0,400.0)];
    [locationListView setContent:[locationsController locations]];
    [locationListView setDelegate:locationsController];
    [locationsController setLocationListView:locationListView];

    var locationScrollView = [[CPScrollView alloc]  initWithFrame:CGRectMake(10.0,65.0,243.0,400.0)];
    [locationScrollView setDocumentView:locationListView];
    [locationScrollView setAutohidesScrollers:YES];
    [[locationScrollView self] setBackgroundColor:[CPColor whiteColor]];
    [self addSubview:locationScrollView];

    mapController = [[MapController alloc] init];

    mapView = [[MKMapView alloc] initWithFrame:CGRectMake(510,65,400,400) apiKey:''     ];
    [mapView setDelegate:self];
    mapController.mapView = mapView;
    [self addSubview:mapView];

    coordinatesLabel = [[CPTextField alloc]     initWithFrame:CGRectMake(510,465,200,35)];
    [coordinatesLabel setTextColor:[CPColor colorWithHexString:@"009900"]];
    [coordinatesLabel setFont:[CPFont systemFontOfSize:14.0]];
    [coordinatesLabel setEditable:NO];
    [coordinatesLabel setStringValue:@"-/-"];
    [mapController setCoordinatesLabel:coordinatesLabel];
    [self addSubview:coordinatesLabel];

    locationsToolbar = [[LocationsToolbar alloc]    initWithFrame:CGRectMake(10.0,467.0,226.0,25.0)];
    [locationsToolbar setDelegate:locationsController];
    [self addSubview:locationsToolbar];

    locationDetailController = [[LocationDetailController alloc] init];
    locationDetailController.mapController = mapController;
    locationsController.locationDetailController = locationDetailController;
    [mapController setDelegate:locationDetailController];

    locationDetailView = [[LocationDetailView alloc]    initWithFrame:CGRectMake(510,490,400,90)];
    [locationDetailView setDelegate:locationDetailController];
    [locationDetailController setLocationDetailView:locationDetailView];
    [self addSubview:locationDetailView];

    searchField = [CPTextField roundedTextFieldWithStringValue:@""  placeholder:@"Location" width:200.0];
    [searchField setFrameOrigin:CGPointMake(510.0,35.0)];
    [searchField setDelegate:self];
    [self addSubview:searchField];

    var searchButton = [[CPButton alloc]    initWithFrame:CGRectMake(710.0,37.0,60.0,24.0)];
    [searchButton setTitle:"Search"];
    [searchButton setTarget:self];
    [searchButton setAction:@selector(searchLocation)];
    [self addSubview:searchButton];

  }
  return self;

}

我不确定我理解你的问题但基本上一个窗口有一个名为内容视图的默认视图。你是这样得的：

var contentView = [theWindow contentView];

在内容视图中，您可以添加子视图（和按钮）。

[contentView addSubview:myLocationView];

这些子视图的位置由子视图的“框架”决定。

[myLocationView setFrame:CGRectMake(10, 10, 100, 100)];

您可以通过删除以前的视图或使用setSubviews消息将内容视图的子视图替换为其他视图。

[contentView setSubviews:[aButton, anotherButton]];

因此，如果您想将一个视图替换为另一个视图，请在其超级视图上使用所需的新视图调用“setSubviews”。希望有助于您入门。

Objective-J卡布奇诺想要主菜单上的按钮列表，当我点击面板刷新时，选择了按钮的UI
