自己随意拖一张图片
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"11.jpg"]]; [imageView setFrame:CGRectMake(10, 30, 300, 200)]; [self.view addSubview:imageView]; [[imageView layer] setShadowOffset:CGSizeMake(5, 5)]; // 阴影的范围 [[imageView layer] setShadowRadius:10]; // 阴影扩散的范围控制 [[imageView layer] setShadowOpacity:1]; // 阴影透明度 [[imageView layer] setShadowColor:[UIColor redColor].CGColor]; // 阴影的颜色 //圆角设置 imageView.layer.cornerRadius = 6; imageView.layer.masksToBounds = YES; //边框宽度及颜色设置 [imageView.layer setBorderWidth:20]; imageView.layer.borderColor = [UIColor blueColor].CGColor; //自动适应,保持图片宽高比 imageView.contentMode = UIViewContentModeScaleAspectFit;
