我需要在UIScrollView
上为此使用MKHorizion
菜单(Scroll视图的子类)绘制动态图像。现在我在scrollview上添加Subview图像。 Loop非常适合在scrollview上添加子视图。现在在我的父类中,我需要触摸滚动视图以获取更新的数据。如果我没有触摸那么它没有显示更新的数据。下面是代码
-(void) reloadData
{
[self deleteAlliTem];
self.itemCount = [dataSource numberOfImagesForMenu:self];
self.backgroundColor = [dataSource backgroundColorForImage:self];
UIFont *buttonFont = [UIFont boldSystemFontOfSize:15];
int buttonPadding = 0;
int tag = kButtonBaseTag;
int xPos = kLeftOffset;
for(int i = 0 ; i < self.itemCount; i ++)
{
NSLog(@"*************************************************************");
NSMutableDictionary *dictData=[dataSource horizMenuImage:self dictForItmeAtIndex:i];
NSString *title=[dictData valueForKey:@"name"] ? [dictData valueForKey:@"name"] : @"";
UIImage* imageItem= [UIImage imageWithData:[Base64 decode:[dictData valueForKey:@"img"]]];
int buttonWidth = 95;
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setTitle:title forState:UIControlStateNormal];
customButton.titleLabel.font = buttonFont;
[customButton setBackgroundImage:[UIImage imageNamed:@"addFriendStrip.png"] forState:UIControlStateNormal];
[customButton setBackgroundImage:[UIImage imageNamed:@"addFriendStrip.png"] forState:UIControlStateSelected];
customButton.tag = tag++;
[customButton addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
customButton.frame = CGRectMake(xPos, 70, buttonWidth + buttonPadding, 25);
customButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
customButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
customButton.titleEdgeInsets =UIEdgeInsetsMake(0, 10,0, 0);
customButton.titleLabel.font = [UIFont fontWithName:@"Overlock-Bold" size:16];
[customButton setTitleColor:[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateNormal];
[customButton setTitleColor:[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateSelected];
UIImageView* itemImageView = [[UIImageView alloc] initWithImage:imageItem];
itemImageView.tag = 200 + customButton.tag;
[itemImageView setFrame:CGRectMake(xPos, 0, buttonWidth + buttonPadding, 95)];
[self addSubview:itemImageView];
[itemImageView release];
itemImageView = nil;
[self addSubview:customButton];
xPos += buttonWidth;
xPos += buttonPadding;
if (i != self.itemCount-1){
xPos += 2.5; //5; // Richa
}
}
self.contentSize = CGSizeMake(xPos, 95);
NSLog(@"############################################################################ - %d",[[self subviews] count]);
[self scrollRectToVisible:CGRectMake(1, 0, self.frame.size.width, self.frame.size.height) animated:YES];
}
请帮我解决这个问题。为什么我需要触摸滚动视图?我需要覆盖其他方法吗?

你检查它是在主线程上吗?可能是你正在使用GCD队列,这就是为什么在触摸之前它不会更新。

只是尝试将您的滚动视图放在首位。我没有正确地回答您的问题,但它可能有所帮助。 让我知道它是否正常工作.. !!!
快乐编码。!!!!
