我需要按宽度按比例调整UI
Image,可能有人有工作代码吗？
例如：
Input: Width: 900 Height: 675. Resize to width: 400 width
Result: Width: 400 Height: 300
请帮忙..
解决方法
检查
this blog post.特别是这两个文件：
> UIImage+Resize.h
> UIImage+Resize.m
也许这对你有用：
UIImage *image = [UIImage imageNamed:@"SomeImage-900x675"]; // SomeImage-900x675.png CGFloat targetWidth = 400.0f; CGFloat scaleFactor = targetWidth / image.size.width; CGFloat targetHeight = image.size.height * scaleFactor; CGSize targetSize = CGSizeMake(targetWidth,targetHeight); UIImage *scaledImage = [image resizedImage:targetSize interpolationQuality:kCGInterpolationHigh];
