如何在调整大小时动画化NSSplitView？ [英] How to animate the NSSplitView while resizing?

问题描述

我想以动画的方式调整 NSSplitView 的程序。
下面是在 SplitView中调整视图大小的代码

在awakeFromNib中：Iam观察 NSSplitViewWillResizeSubviewsNotification

  [[NSNotificationCenter defaultCenter] addObserver：self 
 selector： @selector（splitViewWillResizeSubviewsHandler :) 
 name：NSSplitViewWillResizeSubviewsNotification 
 object：splitView]; 
  
 
 
 
 SplitView调整大小
  NSView * leftSubView = [[splitView subview] objectAtIndex：0]; 
 if（[leftSubView isHidden]）
 {
 [leftSubView setHidden：NO]; 
 [splitView setPosition：0 ofDividerAtIndex：0]; 
} 
 else 
 {
 [leftSubView setHidden：YES]; 
} 
 [splitView adjustSubviews]; 
 [[NSNotificationCenter defaultCenter] postNotificationName：NSSplitViewWillResizeSubviewsNotification object：self userInfo：nil]; 
 
我可以调整splitView的大小。我应该添加animationCode（当rightView移动到replace 
 
 
 
我有两个视图的rects在resize之前和之后。我应该写动画代码。 
解决方案
 Iam能够解决动画。以下代码适用于我
   - （IBAction）resizeViews：（id）sender 
 {
 NSSplitView * splitView = [self splitView]; 
 NSView * leftSubView = [[splitView subviews] objectAtIndex：0]; 
 NSView * rightSubView = [[splitView subviews] objectAtIndex：1]; 
 NSLog（@splitView Frame％@，NSStringFromRect（splitView.frame））; 
 NSLog（@left Frame％@，NSStringFromRect（leftSubView.frame））; 
 NSLog（@right Frame％@，NSStringFromRect（rightSubView.frame））; 
 
 self.lastLeftViewWidth = leftSubView.frame.size.width; 
 
 NSMutableDictionary * collapseMainAnimationDict = [NSMutableDictionary dictionaryWithCapacity：2]; 
 [collapseMainAnimationDict setObject：rightSubView forKey：NSViewAnimationTargetKey]; 
 NSRect newRightSubViewFrame = rightSubView.frame; 
 newRightSubViewFrame.size.width = splitView.frame.size.width; 
 [collapseMainAnimationDict setObject：[NSValue valueWithRect：newRightSubViewFrame] forKey：NSViewAnimationEndFrameKey]; 
 
 NSMutableDictionary * collapseInspectorAnimationDict = [NSMutableDictionary dictionaryWithCapacity：2]; 
 [collapseInspectorAnimationDict setObject：leftSubView forKey：NSViewAnimationTargetKey]; 
 NSRect newLeftSubViewFrame = leftSubView.frame; 
 newLeftSubViewFrame.size.width = 0.0f; 
 newLeftSubViewFrame.origin.x = splitView.frame.size.width; 
 [collapseInspectorAnimationDict setObject：[NSValue valueWithRect：newLeftSubViewFrame] forKey：NSViewAnimationEndFrameKey]; 
 
 NSViewAnimation * collapseAnimation = [[NSViewAnimation alloc] initWithViewAnimations：[NSArray arrayWithObjects：collapseMainAnimationDict，collapseInspectorAnimationDict，nil]]; 
 [collapseAnimation setDuration：0.60f]; 
 [collapseAnimation startAnimation] 
 [splitView adjustSubviews]; 
 [splitView setNeedsDisplay：YES]; 
} 
 
  - （IBAction）normalizeViews：（id）sender 
 {
 NSView * left = [[self.splitView subviews] objectAtIndex：0]; 
 NSView * right = [[self.splitView subviews] objectAtIndex：1]; 
 NSlog（@splitView Frame％@，NSStringFromRect（self.splitView.frame））; 
 NSLog（@left Frame％@，NSStringFromRect（left.frame））; 
 NSLog（@right Frame％@，NSStringFromRect（right.frame））; 
 // [right setFrame：NSMakeRect（0，right.frame.origin.y，right.frame.size.width-118，right.frame.size.height）]; 
 // [left setFrame：NSMakeRect（0，0，118，left.frame.size.height）]; 
 
 left.hidden = NO; 
 
 NSMutableDictionary * expandMainAnimationDict = [NSMutableDictionary dictionaryWithCapacity：2]; 
 [expandMainAnimationDict setObject：right forKey：NSViewAnimationTargetKey]; 
 NSRect newMainFrame = right.frame; 
 newMainFrame.size.width = self.splitView.frame.size.width-self.lastLeftViewWidth; 
 [expandMainAnimationDict setObject：[NSValue valueWithRect：newMainFrame] forKey：NSViewAnimationEndFrameKey]; 
 
 NSMutableDictionary * expandInspectorAnimationDict = [NSMutableDictionary dictionaryWithCapacity：2]; 
 [expandInspectorAnimationDict setObject：left forKey：NSViewAnimationTargetKey]; 
 NSRect newInspectorFrame = left.frame; 
 newInspectorFrame.size.width = self.lastLeftViewWidth; 
 newInspectorFrame.origin.x = self.splitView.frame.size.width-self.lastLeftViewWidth; 
 [expandInspectorAnimationDict setObject：[NSValue valueWithRect：newInspectorFrame] forKey：NSViewAnimationEndFrameKey]; 
 
 NSViewAnimation * expandAnimation = [[NSViewAnimation alloc] initWithViewAnimations：[NSArray arrayWithObjects：expandMainAnimationDict，expandInspectorAnimationDict，nil]]; 
 [expandAnimation setDuration：0.60f]; 
 [expandAnimation startAnimation]; 
 [self.splitView adjustSubviews]; 
 [self.splitView setNeedsDisplay：YES]; 
}

 如何展开并使用动画折叠NSSplitView子视图？ 
 
I would like to animate while resizing NSSplitView programatically.
Here is the code for resizing the view in SplitView

In awakeFromNib: Iam observing the NSSplitViewWillResizeSubviewsNotification
 [[NSNotificationCenter defaultCenter] addObserver:self
            selector:@selector(splitViewWillResizeSubviewsHandler:)
            name:NSSplitViewWillResizeSubviewsNotification
            object:splitView];
SplitView Resize
NSView * leftSubView = [[splitView subviews] objectAtIndex:0];       
if ([leftSubView isHidden]) 
{
    [leftSubView setHidden:NO];
    [splitView setPosition:0 ofDividerAtIndex:0];
}
else 
{
    [leftSubView setHidden:YES];
}
[splitView adjustSubviews];
    [[NSNotificationCenter defaultCenter] postNotificationName:NSSplitViewWillResizeSubviewsNotification object:self userInfo:nil];
I am able to resize the splitView.Where should I add the animationCode.(As rightView moves to replace the leftSubView, I want the resize happen with some delay) ?

I have the rects of the two Views before and after the resize.Where should I write the animation Code.
解决方案
Iam able to solve the animations. Following Code works for me
-(IBAction)resizeViews:(id)sender
    {
        NSSplitView *splitView = [self splitView];
        NSView * leftSubView = [[splitView subviews] objectAtIndex:0];
        NSView * rightSubView = [[splitView subviews] objectAtIndex:1];
        NSLog(@"splitView Frame %@",NSStringFromRect(splitView.frame));
        NSLog(@"left Frame %@",NSStringFromRect(leftSubView.frame));
        NSLog(@"right Frame %@",NSStringFromRect(rightSubView.frame));

        self.lastLeftViewWidth = leftSubView.frame.size.width;

        NSMutableDictionary *collapseMainAnimationDict = [NSMutableDictionary dictionaryWithCapacity:2];
        [collapseMainAnimationDict setObject:rightSubView forKey:NSViewAnimationTargetKey];
        NSRect newRightSubViewFrame = rightSubView.frame;
        newRightSubViewFrame.size.width =  splitView.frame.size.width;
        [collapseMainAnimationDict setObject:[NSValue valueWithRect:newRightSubViewFrame] forKey:NSViewAnimationEndFrameKey];

        NSMutableDictionary *collapseInspectorAnimationDict = [NSMutableDictionary dictionaryWithCapacity:2];
        [collapseInspectorAnimationDict setObject:leftSubView forKey:NSViewAnimationTargetKey];
        NSRect newLeftSubViewFrame = leftSubView.frame;
        newLeftSubViewFrame.size.width = 0.0f;
        newLeftSubViewFrame.origin.x = splitView.frame.size.width;
        [collapseInspectorAnimationDict setObject:[NSValue valueWithRect:newLeftSubViewFrame] forKey:NSViewAnimationEndFrameKey];

        NSViewAnimation *collapseAnimation = [[NSViewAnimation alloc] initWithViewAnimations:[NSArray arrayWithObjects:collapseMainAnimationDict, collapseInspectorAnimationDict, nil]];
        [collapseAnimation setDuration:0.60f];
        [collapseAnimation startAnimation];
        [splitView adjustSubviews];
        [splitView setNeedsDisplay:YES];
    }

-(IBAction)normalizeViews:(id)sender
{
    NSView * left = [[self.splitView subviews] objectAtIndex:0];
    NSView * right = [[self.splitView subviews] objectAtIndex:1];
    NSLog(@"splitView Frame %@",NSStringFromRect( self.splitView.frame));
    NSLog(@"left Frame %@",NSStringFromRect( left.frame));
    NSLog(@"right Frame %@",NSStringFromRect( right.frame));
//    [right setFrame: NSMakeRect(0, right.frame.origin.y, right.frame.size.width-118, right.frame.size.height)];
//    [left setFrame:NSMakeRect(0, 0, 118, left.frame.size.height)];

    left.hidden = NO;

    NSMutableDictionary *expandMainAnimationDict = [NSMutableDictionary dictionaryWithCapacity:2];
    [expandMainAnimationDict setObject:right forKey:NSViewAnimationTargetKey];
    NSRect newMainFrame = right.frame;
    newMainFrame.size.width =  self.splitView.frame.size.width-self.lastLeftViewWidth;
    [expandMainAnimationDict setObject:[NSValue valueWithRect:newMainFrame] forKey:NSViewAnimationEndFrameKey];

    NSMutableDictionary *expandInspectorAnimationDict = [NSMutableDictionary dictionaryWithCapacity:2];
    [expandInspectorAnimationDict setObject:left forKey:NSViewAnimationTargetKey];
    NSRect newInspectorFrame = left.frame;
    newInspectorFrame.size.width = self.lastLeftViewWidth;
    newInspectorFrame.origin.x = self.splitView.frame.size.width-self.lastLeftViewWidth;
    [expandInspectorAnimationDict setObject:[NSValue valueWithRect:newInspectorFrame] forKey:NSViewAnimationEndFrameKey];

    NSViewAnimation *expandAnimation = [[NSViewAnimation alloc] initWithViewAnimations:[NSArray arrayWithObjects:expandMainAnimationDict, expandInspectorAnimationDict, nil]];
    [expandAnimation setDuration:0.60f];
    [expandAnimation startAnimation];
    [self.splitView adjustSubviews];
    [self.splitView setNeedsDisplay:YES];
}
