Question

ios中imageview怎么根据内容的大小缩放

Answer 1

cell imageview的属性是readonly
所以不可变更

可以用这种方法改
UIImage *icon = [UIImage imageWithName:@"xxxxx"];
CGSize itemSize = CGSizeMake(30, 30);
UIGraphicsBeginImageContextWithOptions(itemSize, NO,0.0);
CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
[icon drawInRect:imageRect];

cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Answer 2

2：最后.m设置实现属性 　　@synthesize
