让我介绍一下。我是一名有c,c ++,java经验的狂热程序员(非专业人士),现在从MacOsx上的Objective-C和Cocoa开始。
在我的第一个程序中,我想创建两个垂直分割视图,左边一个(主要)始终打开,右边一个按钮按下显示/隐藏(它的用途是调试输出)。
我已经在Xcode 4.2中看到了我想要的东西,我们可以隐藏/显示导航器/调试/实用程序。我正在寻找“实用程序”行为,这正是我想要的。该垂直视图的用法是从我的程序输出“调试”文本,我正在考虑在NSScrollView中使用NSTextView来模拟“控制台”。我知道我可以使用终端或Xcode的Debug视图,这就是现在正在运行的。我需要这个只是为了学习如何做和改进我的程序。
我已经谷歌了很多并阅读了类似的请求,但我找不到如何做到这一点。
提前感谢您的帮助。

我创建了一个带有2个自定义视图的NSSplitView(垂直),在Interface Builder中有足够的自动调整限制('spring'/'struts')。然后我做了以下事情:
Controller.h
:
@interface Controller : NSWindowController <NSSplitViewDelegate, NSWindowDelegate> {
:
Controller.m
:
// To control the Splitter (next 3 methods)
// =======================================
// The splitter cannot be moved. I always return "widthViewLeft" which is "fixed static sized to the left view width"
// I return NO to resize the left panel and YES to the right panel.
-(CGFloat)splitView:(NSSplitView *)splitView constrainMaxCoordinate:(CGFloat)proposedMax ofSubviewAt:(NSInteger)dividerIndex {
return (widthViewLeft);
}
-(CGFloat)splitView:(NSSplitView *)splitView constrainMinCoordinate:(CGFloat)proposedMin ofSubviewAt:(NSInteger)dividerIndex {
return (widthViewLeft);
}
-(BOOL)splitView:(NSSplitView *)splitView shouldAdjustSizeOfSubview:(NSView *)subview {
return subview != splitViewLeft;
}
// To control the Main Window resize
// =======================================
// I allow to resize if the Right panel is open.
// I restrict to a fixed size if the Right panel is closed(hidden), so I don't allow to resize.
- (NSSize)windowWillResize:(NSWindow *)window toSize:(NSSize)proposedFrameSize
{
if ( [[leftViewController view] isHidden ] ) {
proposedFrameSize.width = widthViewLeft + 2;
proposedFrameSize.height = heightViewLeft + titleBarHeight + 2;
}
return proposedFrameSize;
}
// To HIDE the right panel
// =======================================
//
-(void)handleNotificationHideConsola:(NSNotification *)pNotification
{
NSRect newFrame;
NSSize newMinSize;
NSSize newMaxSize;
// Hide the right panel
[[rightViewController view] setHidden:TRUE];
// Values that do not change
newMinSize.height = [theWindow minSize].height;
newMaxSize.height = [theWindow maxSize].height;
newFrame.origin.x = [theWindow frame].origin.x;
//newFrame.origin.y = [theWindow frame].origin.y;
// Values that change
newMinSize.width = widthViewLeft;
newMaxSize.width = widthViewLeft;
newFrame.size.width = widthViewLeft + 2;
newFrame.size.height = heightViewLeft + titleBarHeight + 2;
newFrame.origin.y = [theWindow frame].origin.y + ([theWindow frame].size.height - newFrame.size.height) ;
// Perform the change
[theWindow setMinSize:newMinSize];
[theWindow setFrame:newFrame display:YES animate:YES];
}
// To SHOW the right panel
// =======================================
//
-(void)handleNotificationShowConsola:(NSNotification *)pNotification
{
if ( [[rightViewController view] isHidden] ) {
NSRect newFrame;
NSSize newMinSize;
// Show the right panel
[[rightViewController view] setHidden:FALSE];
// Values that do not change
newMinSize.height = [theWindow minSize].height;
newFrame.origin.x = [theWindow frame].origin.x;
newFrame.origin.y = [theWindow frame].origin.y ;
// Values that change
newMinSize.width = widthViewLeft + widthViewRigth;
newFrame.size.width = widthViewLeft + widthViewRigth;
newFrame.size.height = newMinSize.height + titleBarHeight;
newFrame.origin.y = [theWindow frame].origin.y - (newFrame.size.height - [theWindow frame].size.height);
// Perform the change
[theWindow setMinSize:newMinSize];
[theWindow setFrame:newFrame display:YES animate:YES];
}
}
再次感谢@markhunte的想法,并希望上面的示例可以帮助其他人。

一个非常粗略的想法。使用 setPosition:ofDividerAtIndex:更改视图的宽度 setPosition:(CGFloat)位置DividerAtIndex:(NSInteger)dividerIndex
声明 CGFloat splitterlength 。
并将其放入applicationDidFinishLaunching中。
splitterlength = splitView.bounds.size.width;
[splitView setPosition:splitterlength ofDividerAtIndex:0];
然后使用此动作
- (IBAction)moveSplitter:(id)sender {
NSArray *splitterViews =splitView.subviews;
CGFloat splitterCheckLength =[[splitterViews objectAtIndex:0]bounds].size.width;
CGFloat openSplitter=splitterlength/2;
if (splitterCheckLength ==openSplitter) {
[splitView setPosition:splitterlength ofDividerAtIndex:0];
}else {
[splitView setPosition:openSplitter ofDividerAtIndex:0];
}
}
使用你想要的长度。
虽然这样说。我会使用普通的customViews并调整它们。这样我就不必担心用户拖动拆分器了。
