是否可以在视图中具有可以重复x或y或两者的模式(例如网格)?有点像css:
background-image:url(pattern.png); background-repeat:重复; //或repeat-x,repeat-y,no repeat;

以下代码将平铺背景图像:
- (void) viewDidLoad {
[[self view] setBackgroundColor: [[UIColor alloc] initWithPatternImage: [UIImage imageNamed: @"background.png"]]];
[super viewDidLoad];
}

是。您可以将图像模式加载为颜色([NSColor withPatternImage:[NSImage imageNamed:@"pattern"]]
),然后像常规颜色一样绘制它:
- (void)drawRect:(NSRect)dirtyRect {
...
// Load the image through NSImage and set it as the current color.
[[NSColor colorWithPatternImage:[NSImage imageNamed:@"pattern"]] set];
// Fill the entire view with the image.
[NSBezierPath fillRect:[self bounds]];
...
}
此代码将在整个视图上重复该模式,但您只需稍加修改就可以使用x-repeat或y-repeat。
