ios – 添加图像进行查看

如何将图像添加到UIView？这是我到目前为止所尝试的：

UIView *imageHolder = [[UIView alloc] initWithFrame:CGRectMake(40,200,280,192)];
UIImage *image = [UIImage imageNamed:@"bloodymoon.jpg"];
[imageHolder addSubview:image]; // Error: Incompatible pointer types
[self.mainView addSubview:imageHolder];

解决方法

试试UIImageView：

UIImageView *imageHolder = [[UIImageView alloc] initWithFrame:CGRectMake(40,192)];
UIImage *image = [UIImage imageNamed:@"bloodymoon.jpg"];
imageHolder.image = image;
// optional:
// [imageHolder sizetoFit];
[self.mainView addSubview:imageHolder];
