【问题标题】:Switching custom views in a window在窗口中切换自定义视图
【发布时间】:2012-06-21 01:57:31
【问题描述】:

我有一个 .xib,它有一个带有 NSToolbar 的窗口,并且有多个自定义视图,所有这些都是同一个 xib 的一部分。当我单击工具栏图标时,它会切换视图,但不会显示该视图上的任何按钮或其他对象。

我知道视图正在切换,因为两个视图的大小不同,并且窗口正在调整

切换视图的代码:

NSInteger tag = [sender tag];

NSView *view = [self viewForTag:tag];
NSView *previousView = [self viewForTag: currentViewTag];
currentViewTag = tag;
NSRect newFrame = [self newFrameForNewContentView:view];

[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:0.1];

if ([[NSApp currentEvent] modifierFlags] & NSShiftKeyMask)
[[NSAnimationContext currentContext] setDuration:1.0];

[[[self.window contentView] animator] replaceSubview:previousView with:view];
[[self.window animator] setFrame:newFrame display:YES];

[NSAnimationContext endGrouping];

    【解决方案1】:

    这可能不是最好的方式,我不确定,但我切换视图的方式是这样的:

    #import "AppDelegate.h"
    
    @implementation AppDelegate
    
    - (void)applicationDidFinishLaunching:(NSNotification *)aNotification
    {
        self.firstSubView = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
        self.secondSubView = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
    
        [self.customView addSubview: self.firstSubView.view];
        self.firstSubView.view.frame = self.customView.bounds;
    
        self.firstViewIsSelected = YES;
    }
    
    - (IBAction)viewSwitched:(id)sender {
        if (self.firstViewIsSelected) {
            [self.firstSubView.view removeFromSuperview];
            [self.customView addSubview: self.secondSubView.view];
            self.secondSubView.view.frame = self.customView.bounds;
        }
        else{
            [self.secondSubView.view removeFromSuperview];
            [self.customView addSubview: self.firstSubView.view];
            self.firstSubView.view.frame = self.customView.bounds;
        }
        self.firstViewIsSelected = !self.firstViewIsSelected;
    }
