NSSplitView

本文代码最终实现界面为

两种方法可以实现divider的上下拖动：

1.调用NSSplitViewDelegate

/* Given a proposed position for one of the dividers of a split view, return a position at which the divider should be placed as the user drags it. If a split view has no delegate, or if its delegate does not respond to this message, the split view behaves as if it has a delegate that responds to this message by merely returning the proposed position. If a split view has a delegate, and the delegate responds to this message, it will be sent repeatedly as the user drags one of the split view's dividers.

- (CGFloat)splitView:(NSSplitView *)splitView constrainSplitPosition:(CGFloat)proposedPosition ofSubviewAt:(NSInteger)dividerIndex;

用此方法要先设置splitview的delegate为当前app（[_splitOuter setDelegate:self];）或

- (CGFloat)splitView:(NSSplitView *)splitView constrainSplitPosition:(CGFloat)proposedPosition ofSubviewAt:(NSInteger)dividerIndex

{

NSLog(@"split view is being dragged");

CGFloat position = proposedPosition;

return position;

}

2.调用通知

- (void) splitViewDidResizeSubviews:(NSNotification *)notification

//- (void) splitViewDidResizeSubviews:(NSNotification *)notification

//{

// NSSplitView *split = [notification object];

// NSString *splitName = [split identifier];

//// NSLog(@"split name is %@",[split identifier]);

// NSArray *allviews = [split subviews];

// if ([splitName isEqualToString:@"split_outer"]) {

// //1.修改split_outer.topview中控件的大小位置

// NSView *topView = [allviews objectAtIndex:0];

// [[self.textViewConsole enclosingScrollView] setFrame:[topView frame]];

// NSView *bottomView = [allviews objectAtIndex:2];

// NSSize bottomSize = [bottomView frame].size;

// NSRect bottomRect = {0,0,bottomSize.width,bottomSize.height};

// [[self.tableViewProgress enclosingScrollView] setFrame:bottomRect];

// //2.修改split_outer.bottomview中控件的大小位置

// NSView *middleView = [allviews objectAtIndex:1];

// NSRect middleRect = [middleView frame];

// NSLog(@"x:%f,y:%f,w:%f,h:%f",middleRect.origin.x,middleRect.origin.y,middleRect.size.width,middleRect.size.height);

// //3. 修改split_outer.middle下拉动时对应其它控件的大小

// NSPoint point = NSMakePoint(0, 0);

// [self.splitInner setFrameOrigin:point];

// [self.splitInner setFrameSize:middleRect.size];

// NSArray *innerSubViews = [self.splitInner subviews];

// NSView *leftTableViewOuterView = [innerSubViews objectAtIndex:0];

// NSSize leftTableViewOuterViewSize = [leftTableViewOuterView frame].size;

// [[self.leftTableView enclosingScrollView] setFrameSize:leftTableViewOuterViewSize];

// [[self.leftTableView enclosingScrollView] setFrameOrigin:point];

// NSView *rightTableViewOuterView = [innerSubViews objectAtIndex:1];

// NSSize rightTableViewOuterViewSize = [rightTableViewOuterView frame].size;

// [[self.rightTableView enclosingScrollView] setFrameSize:rightTableViewOuterViewSize];

// [[self.rightTableView enclosingScrollView] setFrameOrigin:point];

// } else if([splitName isEqualToString:@"split_inner"]){

// NSLog(@"xxxxxxx");
