我有一个PFQueryTableViewController的子类,我试图在容器视图中显示(作为子视图)。我的问题是我无法在tableview中显示自定义单元格。我通过调试验证了以下内容:
我正确地在这里工作,除了细胞实际出现!我错过了什么?
这是我的cellForRowAtIndexPath代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{
static NSString *CellIdentifier = @"RoundCell";
RoundCell* cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
if (cell == nil)
{
cell = [[RoundCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// get string values from Parse
NSString * teeString =[object objectForKey:@"roundTee"];
NSString* courseString = [object objectForKey:@"roundCourse"];
NSString * courseString2 = [[courseString stringByAppendingString:@" - "]stringByAppendingString:teeString];
NSString * dateString = [object objectForKey:@"roundDate"];
NSString * scoreString = [object objectForKey:@"roundScore"];
NSString * differentialString = [object objectForKey:@"roundDifferential"];
cell.courseNameCell.text = courseString2;
cell.dateCell.text = dateString;
cell.scoreCell.text= scoreString;
cell.differentialCell.text=differentialString;
return cell;
}

正确的方法是在cellForRowAtIndexPath中调用自定义单元格。
检查两件基本的事情:
<强> 1。在故事板上并单击“属性”检查器中的单元格,检查该单元格是否具有正确的标识符
<强> 2。以这种方式设置cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{
CustomCell *cell = (CustomCell * )[self.tableView dequeueReusableCellWithIdentifier:@"YOUR CELL NAME" forIndexPath:indexPath];
所以在你的情况下试试:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object{
CustomCell *cell = (CustomCell * )[self.tableView dequeueReusableCellWithIdentifier:@"YOUR CELL NAME" forIndexPath:indexPath];
NSString * teeString =[object objectForKey:@"roundTee"];
NSString* courseString = [object objectForKey:@"roundCourse"];
NSString * courseString2 = [[courseString stringByAppendingString:@" - "]stringByAppendingString:teeString];
NSString * dateString = [object objectForKey:@"roundDate"];
NSString * scoreString = [object objectForKey:@"roundScore"];
NSString * differentialString = [object objectForKey:@"roundDifferential"];
cell.courseNameCell.text = courseString2;
cell.dateCell.text = dateString;
cell.scoreCell.text= scoreString;
cell.differentialCell.text=differentialString;
return cell;
}
不要忘记在File.m中导入自定义单元格的子类
#import "YourCustomCell.h"
并在身份检查器中设置单元格

如果您在XIB中设计了UITableView单元(听起来就是这样),那么就不能使用alloc init
范例来初始化对象。你必须使用:
cell = [[[NSBundle mainBundle] loadNibNamed:@"MyCellXibFile"
owner:nil
options:nil] objectAtIndex:0]

Swift版本(1.2之前):
