我对UIImageView显示图像的方式感到非常失望.

我有以下代码:

UIImageView *imgview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 300, 100)];
imgview.image = [UIImage imageNamed:@"img.JPG"];
imgview.backgroundColor = [UIColor greenColor];
imgview.contentMode = UIViewContentModeScaleAspectFit;
[self.view addSubview:imgview];

我得到的是以下截图:

[图像被拉伸到UIImageView的全宽,甚至没有占据全高]
