不能添加的UIButton到的UIScrollView

Question

Goodevening

虽然我读过有关添加一个UIButton到的UIScrollView它并没有为我工作了很多相关的问题。当我使用UIImages而不是UIButtons时，它就像一个魅力。我在这里错过了什么？ （不介意，如果公司或for循环，人的是正确的，图片的路径也）

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

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

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

     } 
    } 

干杯

[UIImage imageNamed:path]看起来不正确， 尝试[UIImage imageWithData:[NSData dataWithContentsOfFile:path]

---

UIButton *fotoButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
[fotoButton setImage:[UIImage imageWithData:[NSData dataWithContentsOfFile:path] forState:UIControlStateNormal];
