图片不适合UIImageView

Question

I have some base64 data and am trying to put it in my image, which I can do but I can't get it so that it shrinks to just fill the imageView and not make it bigger, here is what I am doing

NSString *base64 =[[NSString stringWithFormat:@"data:image/png;base64,%@", dataString] stringByReplacingOccurrencesOfString:@" " withString:@"+"];
    NSURL *url = [NSURL URLWithString:base64];
    NSData *imageData = [NSData dataWithContentsOfURL:url];
    UIImage *image = [UIImage imageWithData:imageData];
    rdCell.imageView.clipsToBounds = YES;
    rdCell.imageView.contentMode = UIViewContentModeScaleAspectFill;
    [rdCell.imageView setImage:image];

I have also tried this

        NSURL *url = [NSURL URLWithString:base64];
    NSData *imageData = [NSData dataWithContentsOfURL:url];
    UIImage *image = [UIImage imageWithData:imageData];
    rdCell.imageView.contentMode = UIViewContentModeScaleAspectFit;
    [rdCell.imageView setImage:image];

But then I see the image larger than the original size of the image view, why won't it stay inside?

Thanks

Answer 1

您必须改为使用contentMode UIViewContentModeScaleAspectFit ！

UIViewContentModeScaleToFill应该可以解决问题，但是您需要确保能够在屏幕上看到整个图像视图，并提供一定的内容大小会有所帮助。
