我想添加一个带有分页的 UIScrollView,以浏览来 self 现有 View Controller (我的应用程序的 Root View )的不同 View 。我还有标签栏和导航栏 Controller 。我可以向这个 View Controller 添加一个 ScrollView 来完成我想要的吗?如果可以,有人可以为我指明正确的方向吗?
这是我的 View Controller 。

最佳答案
这对我来说非常有效:
为您的 UIScrollView 声明一个属性,并将您的 ViewController 设置为 UIScrollViewDelegate
@interface ViewController : UIViewController<UIScrollViewDelegate>
@property (strong, nonatomic) UIScrollView *theScrollView;
@end
**请注意,我正在使用代码设置我的 UIScrollView,但可以使用 XIB 轻松完成。
在您的 ViewController 的 viewDidLoad: 中
self.theScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.size.width, 300)];
self.theScrollView.delegate = self;
self.theScrollView.pagingEnabled = YES;
self.theScrollView.showsHorizontalScrollIndicator = NO;
self.theScrollView.showsVerticalScrollIndicator = NO;
[self.view addSubview:self.theScrollView];
NSArray *viewArray = [NSArray arrayWithObjects://your UIViews];
for(int i=0; i<viewArray.count; i++)
{
CGRect frame;
frame.origin.x = self.theScrollView.frame.size.width * i;
frame.origin.y = 0;
frame.size = self.theScrollView.frame.size;
UIView *subview = [[UIView alloc] initWithFrame:frame];
[subview addSubview:[viewArray objectAtIndex:i]];
[self.theScrollView addSubview:subview];
}
self.theScrollView.contentSize = CGSizeMake(self.theScrollView.frame.size.width * viewArray.count, self.theScrollView.frame.size.height);
大多数分页 ScrollView 也有一个与之关联的 UIPageControl。为此,请覆盖此 UIScrollViewDelegate 方法:
- (void)scrollViewDidScroll:(UIScrollView *)sender {
CGFloat pageWidth = self.theScrollView.frame.size.width;
int page = floor((self.theScrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
self.thePageControl.currentPage = page;
}

当我使用Bundler时,是否需要在我的Gemfile中将其列为依赖项?毕竟,我的代码中有些地方需要它。例如,当我进行Bundler设置时:require"bundler/setup" 最佳答案 没有。您可以尝试,但首先您必须用鞋带将自己抬离地面。 关于ruby-我需要将Bundler本身添加到Gemfile中吗?,我们在StackOverflow上找到一个类似的问题: https://stackoverflow.com/questions/4758609/

当谈到运行时自省(introspection)和动态代码生成时,我认为ruby没有任何竞争对手,可能除了一些lisp方言。前几天,我正在做一些代码练习来探索ruby的动态功能,我开始想知道如何向现有对象添加方法。以下是我能想到的3种方法:obj=Object.new#addamethoddirectlydefobj.new_method...end#addamethodindirectlywiththesingletonclassclass这只是冰山一角,因为我还没有探索instance_eval、module_eval和define_method的各种组合。是否有在线/离线资
我注意到类定义,如果我打开classMyClass,并在不覆盖的情况下添加一些东西我仍然得到了之前定义的原始方法。添加的新语句扩充了现有语句。但是对于方法定义,我仍然想要与类定义相同的行为,但是当我打开defmy_method时似乎,def中的现有语句和end被覆盖了,我需要重写一遍。那么有什么方法可以使方法定义的行为与定义相同,类似于super,但不一定是子类? 最佳答案 我想您正在寻找alias_method:classAalias_method:old_func,:funcdeffuncold_func#similartoca
我有带有Logo图像的公司模型has_attached_file:logo我用他们的Logo创建了许多公司。现在,我需要添加新样式has_attached_file:logo,:styles=>{:small=>"30x15>",:medium=>"155x85>"}我是否应该重新上传所有旧数据以重新生成新样式?我不这么认为……或者有什么rake任务可以重新生成样式吗? 最佳答案 参见Thumbnail-Generation.如果rake任务不适合你,你应该能够在控制台中使用一个片段来调用重新处理!关于相关公司
