我收到这个错误,我在arm64下编译出现了这个错误：
CGContextSetLineDash(line,lengths,1); //画虚线
我该如何解决这个问题？
- (id)initDashLineWithFrame:(CGRect)frame{
UIImageView *imageView1 = [[UIImageView alloc]initWithFrame:frame];
UIGraphicsBeginImageContext(imageView1.frame.size); //开始画线
[imageView1.image drawInRect:CGRectMake(0,imageView1.frame.size.width,imageView1.frame.size.height)];
CGContextSetLineCap(UIGraphicsGetCurrentContext(),kCGLineCapRound); //设置线条终点形状
float lengths[] = {4,5};
CGContextRef line = UIGraphicsGetCurrentContext();
UIColor *coloreline = [UIColor colorWithRed:156/255.0 green:156/255.0 blue:156/255.0 alpha:1];//r(156,156,1);
CGContextSetStrokeColorWithColor(line,coloreline.CGColor);
CGContextSetLineDash(line,1); //画虚线
CGContextMoveToPoint(line,0.0,5.0); //开始画线
CGContextAddLineToPoint(line,310.0,5.0);
CGContextStrokePath(line);
imageView1.image = UIGraphicsGetImageFromCurrentImageContext();
return imageView1;
}
