ios - 添加图像以查看

Question

如何向 UIView 添加图像？到目前为止，这是我尝试过的:

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];

Answer 1

试试 UIImageView:

UIImageView *imageHolder = [[UIImageView alloc] initWithFrame:CGRectMake(40, 200, 280, 192)];
UIImage *image = [UIImage imageNamed:@"bloodymoon.jpg"];
imageHolder.image = image;
// optional:
// [imageHolder sizeToFit];
[self.mainView addSubview:imageHolder];
