自NSTextView邊界問題

Question

我要讓NSTextView點的邊界，我的drawRect：代碼如下

- (void)drawRect:(NSRect)dirtyRect 
{ 
    [super drawRect:dirtyRect]; 

    CGFloat lineDash[2]; 

    lineDash[0] = 1.0; 
    lineDash[1] = 1.0; 

    NSBezierPath *path = [NSBezierPath bezierPathWithRect:self.bounds]; 
    [path setLineDash:lineDash count:2 phase:0.0]; 
    [path stroke]; 
} 

我ALSE想給文字和邊界之間一些餘量，我的代碼如下

[textView setTextContainerInset:NSMakeSize(0, 10.0)]; 
[textView setString:@"This is a testThis is a testThis is a testThis is a test"]; 

但結果是上邊框丟失，誰知道如何解決這個問題？

您需要繼承NSScrollView而不是NSTextView。然後你會有一個很好的表現。這是可以做到這樣的：

NSScrollView子類：

-(void)tile { 
    id contentView = [self contentView]; 
    [super tile]; 
    [contentView setFrame:NSInsetRect([contentView frame], 1.0, 1.0)]; 
} 

-(void)drawRect:(NSRect)dirtyRect { 
    CGFloat lineDash[2]; 

    lineDash[0] = 1.5; 
    lineDash[1] = 1.5; 

    NSBezierPath *path = [NSBezierPath bezierPathWithRect:self.bounds]; 
    [path setLineDash:lineDash count:2 phase:0.0]; 
    [path setLineWidth:2]; 
    [path stroke]; 
} 

結果：
