我正在尝试制作类似于Objective-C中的应用程序的电话簿。我使用NSDictionary填充UITableViewCell
。我获得了正确的标题,索引和部分,但是我无法为每个标题获得正确的字幕。每个标题始终是相同的字幕。这是我的代码示例:
@interface TableViewController (){
NSDictionary *sarkilar;
NSArray *sarkilarSectionTitles;
NSArray *sarkilarIndexTitles;
NSArray *subtitles;
}
@end
@implementation TableViewController
- (void)viewDidLoad {
[super viewDidLoad];
sarkilar = @{@"A" : @[@"Alayına İsyan"],
@"B" : @[@"Bebek"],
@"E" : @[@"Elbet Birgün Buluşacağız"],
@"Y" : @[@"Yusuf Yusuf"]};
subtitles = [[NSArray alloc]initWithObjects:@"Seslendiren: Mustafa Sandal",
@"Seslendiren: Akın",
@"Seslendiren: Ahmet Özhan",
@"Seslendiren: Acil Servis",nil];
sarkilarSectionTitles = [[sarkilar allKeys] sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
sarkilarIndexTitles = @[@"A", @"B", @"C", @"D", @"E", @"F", @"G", @"H", @"I", @"J", @"K", @"L", @"M", @"N", @"O", @"P", @"Q", @"R", @"S", @"T", @"U", @"V", @"W", @"X", @"Y", @"Z"];
.
.
.
//and in the cell set up i got this:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"TableViewCell";
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSString *sectionTitle = [sarkilarSectionTitles objectAtIndex:indexPath.section];
NSArray *sectionSarkilar = [sarkilar objectForKey:sectionTitle];
NSString *sarki = [sectionSarkilar objectAtIndex:indexPath.row];
cell.textLabel.text = sarki;
cell.detailTextLabel.text = [subtitles objectAtIndex:indexPath.row];
return cell;
}
我将不胜感激!
最佳答案
在您的情况下,有4个部分:“ A”,“ B”,“ E”和“ Y”。
而且每个部分只有1行。
因此,我认为您的cell.detailTextLabel.text = [subtitles objectAtIndex:indexPath.row];
继续获得“ Seslendiren:Mustafa Sandal”的价值吗?
尝试将行更改为cell.detailTextLabel.text = [subtitles objectAtIndex:indexPath.section];
,看问题是否解决。
编辑:
我将sarkilar
字典更改为以下模式:
sarkilar=@{
@"A": @[@{
@"title": @"Alayına İsyan",
@"subtitle": @"Seslendiren: Mustafa Sandal"
},
@{
@"title": @"Title 2",
@"subtitle": @"Subtitle 2"
}],
@"B":.....
.
.
.
.
};
因此,
sarkilar
中的每个对象都是一个字典数组,每个词典都有title
和subtitle
。接着:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"TableViewCell";
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSString *sectionTitle = [sarkilarSectionTitles objectAtIndex:indexPath.section];
NSArray *sectionSarkilar = [sarkilar objectForKey:sectionTitle];
NSDictionary *dict = [sectionSarkilar objectAtIndex:indexPath.row];
NSString *title = [dict objectForKey:@"title"];
NSString *subtitle = [dict objectForKey:@"subtitle"];
cell.textLabel.text = title;
cell.detailTextLabel.text = subtitle;
}
