7. NSView tag

不能在非drawRect函数内部通过NSBezierPath或者CGPathRef绘制内容

CGSize size = self.proView.bounds.size;
CGFloat h = size.height;
CGFloat w = self.tfPro_w.constant / 0.65f;/*重点，计算*/

10. NSScrollView
基本用法
//style，overloy会独立出来scroll的部分，背景透明
_scrollView.scrollerStyle = NSScrollerStyleOverlay;
// 水平和垂直的弹性属性
_scrollView.horizontalScrollElasticity = NSScrollElasticityNone;
_scrollView.verticalScrollElasticity = NSScrollElasticityNone;
_scrollView.scrollerInsets = NSEdgeInsetsMake(0, 0, 0, -20);//NSEdgeInsets(top:0, left:0, bottom:0, right:-20)
_scrollView.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;
_scrollView.backgroundColor = [NSColor clearColor];
_scrollView.drawsBackground = NO;
- 设置偏移，也可以给NSScrollView添加extension(Swift)或Category(OC)。
CGFloat pY = 0;
CGFloat h = NSHeight(_scrollView.bounds);
NSView *documentView = self.scrollView.documentView;
if ( NO == documentView.isFlipped ) {
pY = MAX(NSHeight(_scrollView.bounds), NSHeight(documentView.bounds));
}
[_scrollView scrollPoint:CGPointMake(0, pY - h + _scrollView.fittingSize.height)];// 设置无效
[documentView scrollPoint:CGPointMake(0, pY)];// 粗略值
[documentView scrollPoint:CGPointMake(0, pY - h + _scrollView.fittingSize.height)];// 更为准确的值
[_scrollView.contentView scrollToPoint:CGPointMake(0, pY - h + _scrollView.fittingSize.height)];// 更为准确的值
- NSScrollView与TitleBar重叠时，top会有偏移，下列方法清除偏移。
_scrollView.automaticallyAdjustsContentInsets = NO;
//_scrollView.contentInsets = NSEdgeInsetsMake(-44, 0, 0, 0);// 不用
- 自定义MYScrollView：禁止滑动；嵌套，滑动事件下传；
@interface MYScrollView : NSScrollView
@end
@implementation MYScrollView
//- (void)reflectScrolledClipView:(NSClipView *)cView {
// /*禁止滑动失败*/
//}
- (void)scrollWheel:(NSEvent *)event {
// NSLog(@"%@-%s", NSStringFromClass([self class]), __func__);
// NSLog(@"%s, %@, %@", __func__, self, @(event.phase));
// [super scrollWheel:event];/*禁止滑动:重载scrollWheel:,并且不调用super，无任何实现*/
/**嵌套，滑动事件下传：NSScrollView内嵌套一个MYScrollView，可以随着外侧的NSScrollView一起滚动*/
[self.nextResponder scrollWheel:event];
}
@end
