我想将矩形的UIBezierPath设置为三角形的动画,而不是为路径上的视图设置动画,而是为路径本身设置动画,使其从一种形状变为另一种形状.路径将添加到CALayer

CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.fillColor = [[UIColor whiteColor] CGColor];    
maskLayer.path = [self getRectPath];

-(CGPathRef)getTrianglePath
{
    UIBezierPath* triangle = [UIBezierPath bezierPath];
    [triangle moveToPoint:CGPointZero];
    [triangle addLineToPoint:CGPointMake(width(self.view),0)];
    [triangle addLineToPoint:CGPointMake(0, height(self.view))];
    [triangle closePath];
    return [triangle CGPath];
}

-(CGPathRef)getRectPath
{
    UIBezierPath*rect = [UIBezierPath bezierPathWithRect:self.view.frame];
    return [rect CGPath];
}

你有什么方法可以为UIView着色吗？不是背景颜色,而是整个UIView及其所有子视图.

例如 - 带有星形旋转动画的UIView,即UIView形状不断变化.

从应用程序(iOS android等)发布而不是Web表单.

class someImage(models.Model):
    image = models.ImageField(upload_to= settings.SHARE_IMAGE_UPLOAD_PATH)

如何写视图？它在邮件请求中接收图像.我发现的每件事都与表格相关(服务器新手)

可能重复:
使用更新的Python 2.6.2在Snow Leopard上安装Python映像库(PIL)

运行MAC 10.7.2在尝试安装PIL时,在解决了许多gcc问题后,安装将退出此行:

/Developer/SDKs/MacOSX10.6.sdk/usr/include/stdarg.h:4:25:错误:stdarg.h:没有这样的文件或目录

我正在使用这一行进行安装:

env ARCHFLAGS="-arch i386 -arch x86_64" easy_install PIL
