如何在iPhone / iPad中实现水平画廊

UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 35, self.frame.size.width, self.frame.size.height-35)];
[self.scrollView setScrollEnabled:YES];
[self.scrollView setDelegate:self];
 self.scrollView.backgroundColor = [UIColor clearColor];
 [self.scrollView setShowsHorizontalScrollIndicator:NO];
 [self.scrollView setIndicatorStyle:UIScrollViewIndicatorStyleDefault];
 scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
 scrollView.contentMode = UIViewContentModeScaleToFill;
 [self.scrollView setContentSize:CGSizeMake(\"GIVE YOUR WIDTH\",0)];
[self.view addSubview:scrollView];
