Question

尝试使用initWithStyle运行以下代码：UITableViewCellStyleSubtitle但字幕未显示。你能告诉我什么是错的吗？

提前致谢！

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize listData;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSArray *array = [[NSArray alloc] initWithObjects:@"Sleepy", @"Sneezy", @"Bashful", @"Happy", @"Doc", @"Grumpy", @"Dopey", @"Thorin", @"Dorin", @"Nori", @"Ori", @"Balin", @"Dwalin", @"Fili", @"Kili", @"Oin", @"Gloin", @"Bifur", @"Bofur", @"Bombur", nil];
    self.listData = array;
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    self.listData = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

#pragma mark -
#pragma mark Table View Data Source Methods
- (NSInteger)tableView:(UITableView *)tableView
    numberOfRowsInSection:(NSInteger)section
{
    return [self.listData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc]
                initWithStyle:UITableViewCellStyleSubtitle 
                reuseIdentifier:SimpleTableIdentifier];
    }

    UIImage *image = [UIImage imageNamed:@"star.png"];
    cell.imageView.image = image;

    NSUInteger row = [indexPath row];
    cell.textLabel.text = [listData objectAtIndex:row];
    return cell;

    if (row < 7)
        cell.detailTextLabel.text = @"Mr. Disney";
    else
        cell.detailTextLabel.text = @"Mr.Tolkien";
}

@end

Answer 1

return cell;

应该是最后一行。它在设置detailTextLabel的{{1}}属性之前返回。

此外，您应该收到Xcode关于“无法访问的代码”的警告。
