所以我有一个循环XML文档的方法。该文档得到了许多答案值，这些答案值正在被提取并以UISegmentedControls的形式打印在屏幕上。 我现在得到的代码是：
- (void) traverseElement:(TBXMLElement *)element {
static CGFloat y = 300.0f;
static CGFloat dynamicHeight = 400.0f;
static int segmentId = 1;
do {
if([[TBXML elementName:element] isEqualToString:@"wcqAnswerValues"]) {
NSString *segmentItemsStr = [TBXML textForElement:element];
NSArray *segmentItemsArray = [segmentItemsStr componentsSeparatedByString:@";"];
answer = [[UISegmentedControl alloc] initWithItems:segmentItemsArray];
answer.frame = CGRectMake(50, y, 400, 40);
[answer addTarget:self action:@selector(textpopup:) forControlEvents:UIControlEventValueChanged];
answer.segmentedControlStyle = UISegmentedControlStyleBar;
answer.tag = segmentId;
[scrollView addSubview:answer];
scrollView.contentSize = CGSizeMake(768, dynamicHeight);
[formulierText removeFromSuperview];
[answer release];
y += 40.0f;
dynamicHeight += 40.0f;
segmentId++;
}
if ([[TBXML elementName:element] isEqualToString:@"formdata"]) {
y = 300.0f;
dynamicHeight = 400.0f;
segmentId = 1;
}
// if the element has child elements, process them
if (element->firstChild)
[self traverseElement:element->firstChild];
// Obtain next sibling element
} while ((element = element->nextSibling));
}
-(void)textpopup:(UISegmentedControl *)sender {
if (sender.tag == 1) {
// if the tag of the sender is 1, then do something.
}
}
我想要实现的目标是：
屏幕上打印的每个UISegmentedControl必须具有唯一的编号或ID，以便我可以单独为其分配操作。实现这一目标的最佳方法是什么？
修改 固定它。我会更新我的代码。
