Question

我创建了一个像小组这样的跳板,其中包括:

-(void)configurePanel{

self.criteriaPanel.scrollEnabled=YES;
self.criteriaPanel=[[UIScrollView alloc] initWithFrame:CGRectMake(
                                                                0.0f, 
                                                                0.0f, 
                                                                [UIScreen mainScreen].bounds.size.width,
                                                                (BUTTON_HEIGHT+(3*BUTTON_Y_OFFSET))
                                                                )];

UIView *scrollViewContent=[[UIView alloc]init];
NSArray *criteriaTypeButtonTitles=[NSArray arrayWithObjects:
                                 @"Option1",
                                 @"Option2",
                                 @"Option3",
                                 @"Option4",
                                 @"Option5",
                                 @"Option6",
                                 nil
                                 ];

for (int i=0; i<[criteriaTypeButtonTitles count]; i++) {
  UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
  button.tag=i;
  button.frame = CGRectMake(
                          (((BUTTON_X_OFFSET*i)+(BUTTON_WIDTH*i))+BUTTON_X_OFFSET)
                          , BUTTON_Y_OFFSET
                          , BUTTON_WIDTH
                          , BUTTON_HEIGHT
                          );  
  [button setTitle:[criteriaTypeButtonTitles objectAtIndex:i] forState:UIControlStateNormal];
  [button setTitleColor:[UIColor blueColor] forState:UIControlStateHighlighted];
  button.titleLabel.font=[UIFont systemFontOfSize:13.0f];
  [button setBackgroundColor:[UIColor grayColor]];
  [button.layer setCornerRadius:10.0f];
  [button.layer setBorderWidth:1.0f];
  [button addTarget:self action:@selector(sortByButtonTap:) forControlEvents:UIControlEventTouchDown];
  [scrollViewContent addSubview:button];
}

//based upon # of buttons
self.criteriaPanel.contentSize=CGSizeMake(
                                        (([criteriaTypeButtonTitles count]*BUTTON_WIDTH)+([criteriaTypeButtonTitles count]*BUTTON_X_OFFSET)),
                                        (BUTTON_HEIGHT+(2*BUTTON_Y_OFFSET)));
[self.criteriaPanel addSubview:scrollViewContent];
[self.view addSubview:self.criteriaPanel];
}

小组显示的是正确的,是滚动的,但 never子的主食(ByButtonTap:)从未被叫到。我怀疑这一点与《发展概览》所载观点中所载的纽州有关。在阅读了其他一些问题和一些特约之后,我仍然可以说明解决办法是什么。

EDIT: I experimented w/ adding the buttons to the UIScrollView (self.criteriaPanel) directly and the button taps call sortByButtonTap: so it is something to do w/ the buttons being in the scrollViewContent.

Answer 1

您也许需要为纽芬兰州制定<代码>用户可交易<>编码>,以备接收触动活动:

[scrollViewContent setUserInteractionEnabled:YES];

Answer 2

如果你试图:

[button setExclusiveTouch:YES];

但是,当他们处于同样处理触动事件的观念之中时,他们往往会不正常地工作。

Answer 3

3. 遵循您的询问守则,

Add UIButton in Scrollview

    scrollview.pagingEnabled = YES;
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.frame = CGRectMake();
    [button setTitle:@"X" forState:UIControlStateNormal];
    [button setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(btnCloseClicked:withEvent:) forControlEvents:UIControlEventTouchUpInside];
    [button addTarget:self action:@selector(btnCloseDraged:withEvent:) forControlEvents:UIControlEventTouchDragInside];
    [button addTarget:self action:@selector(btnCloseDragedEnd:withEvent:) forControlEvents:UIControlEventTouchDragExit];
    [scrollview addSubview:button];
    scrollview.userInteractionEnabled = YES;

you can put this three methods of button manually.

让我知道你是否仍然有疑问。

Answer 4

而不是:

[button addTarget:self 
           action:@selector(sortByButtonTap:) 
 forControlEvents:UIControlEventTouchDown];

审判:

[button addTarget:self 
           action:@selector(sortByButtonTap:) 
 forControlEvents:UIControlEventTouchUpInside];

Answer 5

我认为,你的问题只是把错误的<条码>查询/编码>贴在<条码>上。从<条码>ControlEventTouchDown/code>改为<条码>。如果您在<代码>内连接。界面构建器将始终将其置于之上。 UIControlEvent:

另一个原因是:

页: 1 观点控制了互动关系,因为它需要知道你是否希望进行交流。如果您在<条码>内登上。意见可以查阅,但总是稍有延误。因此,你可能会改变<代码>的环境。缩略语观点:

可在<条码>中查询和<条码>查询。
