Ios Can'；t将UIButton添加到UIScrollView

晚安

虽然我读过很多关于在UIScrollView中添加UIButton的相关问题，但对我来说并不适用。当我使用UIImages而不是UIButtons时，它就像一个符咒。我错过了什么？（不要介意if's或for循环，所有这些都是正确的，还有图像的路径）

for（int j=0；j<[子类别计数]；j++）{
NSArray*产品=[子类别对象索引：（j）]；
int posX=0；
for（int k=1；k
[UIImage imageNamed:path]
看起来不正确，
请尝试
[UIImage imageWithData:[NSData dataWithContentsOfFile:path]


在[fotoButton setImage:[UIImage IMAGENAME:path]forState:UIControlStateNormal]；UIImage IMAGENAME部分不正确，请尝试添加此[UIImage imageWithData:[NSData DATAHWITH CONTENTS OFFILE:path]；您刚刚成就了我的一天！谢谢！这确实是个错误。Thilina Hewagama也这么说。无论如何，谢谢！
 for(int j = 0; j < [subcategorie count]; j++){

        NSArray *product = [subcategorie objectAtIndex:(j)];
        int posX = 0;
        for(int k = 1; k <= [product count]; k++){

            if((i-1) == currentCategory ){
                //NSString *fotoName = [NSString stringWithFormat:@"images/product/%@/%@_%i.png",self.categorieen[(i-1)] ,self.categorieen[(i-1)] , k];

                NSString *fotoName = [NSString stringWithFormat:@"%@_%i",self.categorieen[(i-1)] , k];

                NSString *currentCategory = [NSString stringWithFormat:@"images/product/%@/", self.categorieen[(i-1)]];
                NSString *path = [[NSBundle mainBundle] pathForResource:fotoName ofType:@"png" inDirectory:currentCategory];

                UIButton *fotoButton = [UIButton buttonWithType:UIButtonTypeCustom];
                [fotoButton setImage:[UIImage imageNamed:path] forState:UIControlStateNormal];
                fotoButton.frame = CGRectMake(posX, 252, 718, 520);
                fotoButton.backgroundColor = [UIColor clearColor];

                self.scrollview.contentSize = CGSizeMake(posX, 252);
                [self.scrollview setBounces:YES];
                [self.scrollview setPagingEnabled:YES];

                [self.scrollview bringSubviewToFront:fotoButton];
                [self.scrollview setUserInteractionEnabled:YES];

                self.scrollview.userInteractionEnabled = YES;
                [self addSubview: self.scrollview];
                posX += 718;

                NSLog(@"Fotolink = %@", fotoName);
            }

        }
    }

UIButton *fotoButton = [UIButton buttonWithType:UIButtonTypeCustom];
