问题是...
我有一条路径,我创建了一个在其中绘制它的视图。视图具有相同的路径维度。然后,我创建了第二个视图,在其中我覆盖了 sizeThatFit: 方法,因此第一个视图被缩放,直到第二个视图的所有空间都已满(这就是我对 sizeThatFit: 方法所做的事情的想法!我不知道它是否正确)。那是代码:
CGRect rect = CGPathGetBoundingBox(objPath);
CGRect areaPath = CGRectMake(x, y, rect.size.width, rect.size.height);
FirstView* first = [[FirstView alloc] initWithFrame:areaPath andObjPath:objPath];
SecondView* second = [[SecondView alloc] initWithFrame:CGRectMake(x, y, 200, 200)];
[second addSubview:first];
在 SecondView 我已经覆盖了 sizeThatFit: 方法!
我不知道为什么它不起作用!路径始终具有相同的维度。我会采取一条路径并将其绘制在路径具有他的维度的视图中。因此,例如,如果路径的 boundingBox 是 [10,10] 并且视图是 [100,100],我希望该路径变得与视图维度一样大。我能怎么做 ??
我希望问题足够清楚。对不起我的英语不好 :)
这是 FirstView.m:
@synthesize objPath;
- (id)initWithFrame:(CGRect)frame andObjPath:(CGMutablePathRef)path {
self = [super initWithFrame:frame];
if (self) {
// Initialization code.
objPath = CGPathCreateMutable();
CGRect rect = CGPathGetBoundingBox(path);
CGAffineTransform trans = CGAffineTransformMake(10, 0, 0, 10, self.bounds.size.width, self.bounds.size.height);
CGPathAddPath(objPath, &trans, path);
CGRect pathContainer = CGPathGetBoundingBox(path);
CGPathAddRect(objPath, &trans, pathContainer);
CGPathCloseSubpath(objPath);
}
return self;
}
- (void)drawRect:(CGRect)rect {
// Drawing code.
CGContextRef current = UIGraphicsGetCurrentContext();
CGContextAddPath(current, objPath);
CGContextSetLineWidth(current, 0.6);
CGContextSetRGBStrokeColor(current, 0xff / 255.0, 0x40 / 255.0, 0x40 / 255.0, 1);
CGContextSetRGBFillColor(current, 0xff / 255.0, 0xc1 / 255.0, 0xc1 / 255.0, 1);
CGContextDrawPath(current, kCGPathFillStroke);
}
编辑:
如果我做
FirstView* first = [[FirstView alloc] initWithFrame:areaPath andObjPath:objPath];
SecondView* second = [[SecondView alloc] initWithFrame:CGRectMake(x, y, 200, 200)];
[second addSubview:first];
[first sizeToFit];
并在 SecondView.mi 覆盖 sizeThatFit 方法中,安装第一个视图!!!问题是路径也不合适!!!它始终具有相同的尺寸:(

我也尝试过这种方式:
FirstView* first = [[FirstView alloc] initWithFrame:areaPath andObjPath: objPath];
[first setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
[first setContentMode:UIViewContentModeScaleAspectFit];
SecondView* second = [[SecondView alloc] initWithFrame:CGRectMake(x, y, 200, 200)];
second.autoresizesSubviews = YES;
[second setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
[second setContentMode:UIViewContentModeCenter];
[second addSubview:first];
但是什么都没有!压力很大.... :'(
请问我需要帮助!
