更改图片的size（用于限制上传图片大小）
UIImage+PPCategory.h(下面的方法在这里)
- (UIImage *)scaleToFitSizeIfNeed:(CGSize)bounds
{
CGFloat factor1 = bounds.width/self.size.width;
CGFloat factor2 = bounds.height/self.size.height;
CGFloat factor = MIN(factor1, factor2);
if (factor >= 1) {
return self;
}
// return [self scaleByFactor:factor];
CGFloat resultWidth = self.size.width * factor;
CGFloat resultHeight = self.size.height * factor;
return [self scaleToSize:CGSizeMake(resultWidth, resultHeight)];
}
