以下代碼用於從URL獲取數據。我想選擇一個有限的3行選擇.. Plz幫助我解決這個問題。 TIA僅限於從URL中選擇UITableView中的行
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [self.countriesArr count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSUInteger row = [indexPath row];
static NSString *MyIdentifier = @"tableCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (CustomCell *) currentObject;
}
}
}
NSDictionary *thisRow = [self.countriesArr objectAtIndex:row];
if(_WSConstCountryID !=nil && ![_WSConstCountryID isEqual:@"0"] && ![_WSConstCountryID isEqual:@""] && _WSConstCountrySelectedIndex ==row )
{
cell .accessoryType=UITableViewCellAccessoryCheckmark;
