UIImage方法不被调用
我想操纵视图上的UIImage对象。但是,当我尝试调用上的UIImage类的任何方法,它会抛出异常UIImage方法不被调用

下面是我使用的代码:
UIImage *test = [[UIImage alloc] init];
test = [UIImage imageNamed:@"image0.jpg"];
[test scaleToSize:CGSizeMake(40.0f, 40.0f)];
FIRST定义图像大小,然后它的规模。
UIImage *test = [[UIImage alloc] init;
test = [UIImage imageNamed:@"image0.jpg"];
[test scaleToSize:CGSizeMake(40.0f, 40.0f)];
试试这条线code.Or使用这个图像中的UIImageView
问题出在'scaleToSize'上。它不在UIImage中实现。 – esh 2013-02-14 10:06:56
我在故事板项目中使用https://github.com/OmidH/Filtrr – 2013-02-14 10:12:24
将此用于图像Image.transform = CGAffineTransformMakeScale(2,2); – user2064700 2013-02-14 10:14:41
UIImage没有实现scaleToSize:方法。你正尝试使用一些第三方库可能? – Vladimir 2013-02-14 10:03:32
删除scaleToSize,因为它不支持UIImage – 2013-02-14 10:07:24
你没有在'scaleToSize'行上得到警告吗? – esh 2013-02-14 10:07:53
