objective-c - NSBezierPath 添加了不需要的倒矩形

Question

我有一个自定义 NSView 与我的 xib 中的自定义视图链接。

1. 视图中的代码：

   @implementation GDStatusPopoverActivateButton
   - (void)drawRect:(NSRect)dirtyRect {
       NSBezierPath* path = [GDAssets getPathForTimesIconWithRect: self.bounds];
       NSAffineTransform* transformer = [[NSAffineTransform alloc] init];
       [transformer scaleBy: 0.25];
       [path transformUsingAffineTransform: transformer];
       [[NSColor blackColor] setFill];
       [path fill];
       [super drawRect: dirtyRect];
   }
   @end
   

2. 路径代码（GDAssets getPathForTimesIconWithRect 调用）。

   + (NSBezierPath *) getPathForTimesIconWithRect: (NSRect) rect {
       NSBezierPath* timesPath = [NSBezierPath bezierPathWithRect: rect];
       [timesPath moveToPoint: NSMakePoint(128, 240.48)];
       [timesPath curveToPoint: NSMakePoint(15.52, 128) controlPoint1: NSMakePoint(65.88, 240.48) controlPoint2: NSMakePoint(15.52, 190.12)];
       [timesPath curveToPoint: NSMakePoint(128, 15.51) controlPoint1: NSMakePoint(15.52, 65.88) controlPoint2: NSMakePoint(65.88, 15.51)];
       [timesPath curveToPoint: NSMakePoint(240.48, 128) controlPoint1: NSMakePoint(190.12, 15.51) controlPoint2: NSMakePoint(240.48, 65.88)];
       [timesPath curveToPoint: NSMakePoint(128, 240.48) controlPoint1: NSMakePoint(240.48, 190.12) controlPoint2: NSMakePoint(190.12, 240.48)];
       [timesPath closePath];
       [timesPath moveToPoint: NSMakePoint(256, 128)];
       [timesPath curveToPoint: NSMakePoint(128, 0) controlPoint1: NSMakePoint(256, 57.31) controlPoint2: NSMakePoint(198.69, 0)];
       [timesPath curveToPoint: NSMakePoint(0, 128) controlPoint1: NSMakePoint(57.31, 0) controlPoint2: NSMakePoint(0, 57.31)];
       [timesPath curveToPoint: NSMakePoint(128, 256) controlPoint1: NSMakePoint(0, 198.69) controlPoint2: NSMakePoint(57.31, 256)];
       [timesPath curveToPoint: NSMakePoint(256, 128) controlPoint1: NSMakePoint(198.69, 256) controlPoint2: NSMakePoint(256, 198.69)];
       [timesPath closePath];
       return timesPath;
   }

结果：

Answer 1

这条线是罪魁祸首

NSBezierPath* timesPath = [NSBezierPath bezierPathWithRect: rect];

解决方案：

NSBezierPath* timesPath = [NSBezierPath bezierPath];
