[英]in UITableView, can I have two sections with the cells of each section to be variable length?
[英]Troubles with uitableview sections - cells are repeating in each section
在此先感謝您的幫助,但是我在將代碼包起來時遇到了麻煩。 我正在嘗試將效果很好的現有uitable分為4個部分。 如您所見,我有4個部分,每個部分的行數各不相同,每個部分的名稱也不同。 編譯時,各節正確放置,但重復單元格。 我已經嘗試了關於該主題的其他帖子以及Google信息中的各種方法,但是我不斷收到很多錯誤。 如果有人可以告訴我我遺漏的內容,我將不勝感激! 謝謝。
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 4;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
switch (section) {
case 0:
return 2;
break;
case 1:
return 3;
break;
case 2:
return 2;
break;
case 3:
return 1;
break;
}
return 0;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *sectionHeader = nil;
if(section == 0) {
sectionHeader = @"Section 1";
}
if(section == 1) {
sectionHeader = @"Section 2";
}
if(section == 2) {
sectionHeader = @"Section 3";
}
if(section == 3) {
sectionHeader = @"Section 4";
}
return sectionHeader;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
[cell.textLabel setNumberOfLines:2];
}
cell.textLabel.font = [UIFont systemFontOfSize:14.0];
cell.detailTextLabel.font = [UIFont systemFontOfSize:11.5];
switch (indexPath.row) {
// I would like these in Section One
case 0:
[cell.textLabel setText:@"Cell one"];
[cell.detailTextLabel setText:@"subtext one"];
break;
case 1:
[cell.textLabel setText:@"Cell two"];
[cell.detailTextLabel setText:@"subtext two"];
break;
// And these in Section Two
case 2:
[cell.textLabel setText:@"Cell three"];
[cell.detailTextLabel setText:@"subtext three"];
break;
case 3:
[cell.textLabel setText:@"Cell four"];
[cell.detailTextLabel setText:@"subtext four"];
break;
case 4:
[cell.textLabel setText:@"Cell five"];
[cell.detailTextLabel setText:@"subtext five"];
break;
// And these in Section Three
case 5:
[cell.textLabel setText:@"Cell six"];
[cell.detailTextLabel setText:@"subtext six"];
break;
case 6:
[cell.textLabel setText:@"Cell seven"];
[cell.detailTextLabel setText:@"subtext seven"];
break;
// And this in Section four
case 7:
[cell.textLabel setText:@"Cell eight"];
[cell.detailTextLabel setText:@"subtext eight"];
break;
default:
break;
}
return cell;
}
您必須添加一個
switch (indexPath.section)
在cellForRowAtIndexPath中。
或if-else子句。
像這樣的東西:
if (indexPath.section == 0 && indexPath.row == 0)
{
// for the first row in the first section
}
else if (indexPath.section == 3 && indexPath.row == 2)
{
// for the 4 section and 3 row
}
