我有这种格式的plist:
我目前显示了plist的所有内容。我的主要问题是这个
如何仅根据类别显示?我将有3个类别,我想让用户能够在选择中看到该类别的项目。看看我的第一个项目,类别名称是'main'。如果用户选择主要我只需要显示主要类别项目。
我该如何做到这一点?
'
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if( [[UIDevice currentDevice] userInterfaceIdiom]== UIUserInterfaceIdiomPhone) {
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
}
cell.textLabel.text=[[self.content objectAtIndex:indexPath.row] valueForKey:@"recipeName"];
// NSInteger rating;
//NSString *reason;
// rating = [[self.content objectAtIndex:indexPath.row] valueForKey:@"rating"];
return cell;
// Configure the cell...
'
含量
synthesize tableView,content=_content;
-(NSArray*) content {
if(!_content){
NSString *path = [[NSBundle mainBundle] pathForResource:@"recipes" ofType:@"plist" ];
_content = [[NSArray alloc] initWithContentsOfFile:path];
}
return _content;
}
segue part
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"showDetail"]) {
// Get destination view
detailViewController *destViewController = [segue destinationViewController];
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSInteger tagIndex = [(UIButton *)sender tag];
destViewController.recipeName =[[self.content objectAtIndex:indexPath.row] valueForKey:@"recipeName"];
destViewController.recipeDetail =[[self.content objectAtIndex:indexPath.row] valueForKey:@"recipeDetail"];
destViewController.recipeIngredients =[[self.content objectAtIndex:indexPath.row] valueForKey:@"recipeIngredients"];
这些是主要部分
答案 0 :(得分:1)
我会创建一个新属性来保留已过滤的列表:
@property(nonatomic, strong) NSMutableArray *filteredContent;
然后更改tableView和segue方法,以便在过滤器处于活动状态时,它们将访问self.filteredContent数组而不是self.content。
最后,将过滤器更改为main时:
NSMutableArray *array = [NSMutableArray array];
for (NSDictionary *dictionary in self.content)
if ([[dictionary objectForKey:@"category"] isEqualToString:@"main"])
[array addObject:dictionary];
self.filteredContent = array; //filtered list
[self.tableView reloadData]; //update the table view
希望它能满足您的需求...
