嗨我在過去兩天到處尋找&找不到任何適合我的東西。我設法從網址中提取數據，並在日誌中顯示每一個元素和值。不知道如何將TBXML網址數據添加到我的表格視圖
我無法弄清楚的一步是如何將它添加到我的「events」數組中，而不必手動搜索每個字符串，因爲它自動爲我執行（如我的日誌中所見）。
這裏是我使用loadURL方法：
- (void)loadURL {
// Create a success block to be called when the asyn request completes
TBXMLSuccessBlock successBlock = ^(TBXML *tbxmlDocument) {
NSLog(@"PROCESSING ASYNC CALLBACK");
// If TBXML found a root node, process element and iterate all children
if (tbxmlDocument.rootXMLElement)
[self traverseElement:tbxmlDocument.rootXMLElement];
};
// Create a failure block that gets called if something goes wrong
TBXMLFailureBlock failureBlock = ^(TBXML *tbxmlDocument, NSError * error) {
NSLog(@"Error! %@ %@", [error localizedDescription], [error userInfo]);
};
// Initialize TBXML with the URL of an XML doc. TBXML asynchronously loads and parses the file.
tbxml = [[TBXML alloc] initWithURL:[NSURL URLWithString:@"http://somexml.com/xml"]
success:successBlock
failure:failureBlock];
events = [NSMutableArray array]; }
這裏是我的traverseElement方法：
- (void) traverseElement:(TBXMLElement *)element {
do {
// Display the name of the element
NSLog(@"%@",[TBXML elementName:element]);
// iterate all child elements of tbxml.rootXMLElement that are named "author"
[TBXML iterateAttributesOfElement:element withBlock:^(TBXMLAttribute *attribute, NSString *name, NSString *value) {
// Display name and value of attribute to the log window
NSLog(@"%@->%@ = %@",[TBXML elementName:element], name, value);
}];
// if the element has child elements, process them
if (element->firstChild) [self traverseElement:element->firstChild];
// Obtain next sibling element
} while ((element = element->nextSibling));
}
這裏是我拉的XML：
<resultsPage totalEntries="6" perPage="50" page="1" status="ok">
<results>
<event uri="http://somexml.com/xml" popularity="0.863682" displayName="Radio 1's Hackney
Weekend 2012" id="9234656" type="Festival" status="ok">
<location city="London, UK" lng="-0.128" lat="51.5078"/>
<series displayName="Radio 1's Hackney Weekend"/>
<end time="" date="2012-06-24" datetime=""/>
<start time="" date="2012-06-23" datetime=""/>
<performance displayName="Lucy Labeaux" billingIndex="5" id="23336188" billing="headline">
<artist uri="http://www.somexml.com/artistxml" displayName="Lucy Labeaux" id="1168415">
<identifier href="http://somexml.com.xml" mbid="4593d49a-7f67-46ba-9ec0-126bd676286f"/>
</artist>
</performance>
我的日誌看起來像這樣：
PROCESSING ASYNC CALLBACK
resultsPage
resultsPage->totalEntries = 6
resultsPage->perPage = 50
resultsPage->page = 1
resultsPage->status = ok
results
event
event->uri = http://example.com
event->popularity = 0.863682
event->displayName = Cooled Up Week 2012
event->id = 9234656
event->type = Festival
event->status = ok
location
location->city = London, UK
location->lng = -0.128
location->lat = 51.5078
series
series->displayName = Cooled Up Week 2012
end
end->time =
end->date = 2012-06-24
end->datetime =
start
start->time =
start->date = 2012-06-23
start->datetime =
performance
performance->displayName = Lucy Labeaux
performance->billingIndex = 1
所以，現在我已經經歷了所有元素，屬性等，我如何將它鏈接到我的表視圖和行數？我想放棄，請幫助！我非常感謝你的時間，非常感謝你！
你試圖把什麼特定的數據從你的表格視圖放入？ – 2012-04-28 14:23:08
從事件中，我試圖拉出uri和displayName。從城市的位置，lng，＆lat。從開始，時間和日期。我也試圖將我的行數分配給totalEntries的數量，但似乎無法弄清楚這一點。 – Year3000 2012-04-28 19:47:06
我在想這些問題，但我不確定：'TBXMLElement * event = [TBXML childElementNamed：@「event」parentElement：element]; NSString * uri = [TBXML valueOfAttributeNamed：@「uri」forElement：event]; NSString * venue = [TBXML valueOfAttributeNamed：@「displayName」forElement：event]; [events addObject：[NSArray arrayWithObjects： [TBXML textForElement：event]， uri，venue，nil]]; – Year3000 2012-04-28 20:15:57
