Question

我有一个带有数千个Array的plist。每个数组都包含有51个项目的Dictionary.thats意味着总共有大约40,000个数据，我已正确填入UITableView。我输入10左右Array进入UITableView ..它以良好的视图显示行...但是当我超越40个数组时...... UITableView变得奇怪。你甚至无法理解。 first 。

和UITableView在...

之下

sec

我也试过每个部分的Exapanded行。这对我也不起作用..我该怎么办？

编辑代码

-(void)ViewDidLoad
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"sam" ofType:@"plist"];

//Load the file in a dictionnary
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];

self.myData = dict;

//SORTING THE DICTIONARY    
NSArray *dicoArray = [[self.myData allKeys] sortedArrayUsingComparator:^(id firstObject, id secondObject) {
    return [((NSString *)firstObject) compare:((NSString *)secondObject) options: NSCaseInsensitiveSearch];
}];

self.mySections = dicoArray;

NSLog(@"path values%@",tableDict);


}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{



return [self.mySections count];



}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

 if ([self tableView:tableView canCollapseSection:section])
 {
    if ([expandedSections containsIndex:section])
    {

NSString *key = [self.mySections objectAtIndex:section];
NSArray *dataInSection = [[self.myData objectForKey:key] objectAtIndex:0];
return [dataInSection count];
    }
    return 1;
  }
return 1;
  }


-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *key = [self.mySections objectAtIndex:section];
 return [NSString stringWithFormat:@"%@", key];
}


-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
return self.mySections;
}



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

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
}

// Configure the cell...

NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];



NSString *key = [self.mySections objectAtIndex:section];

NSDictionary *dataForSection = [[self.myData objectForKey:key] objectAtIndex:0];
NSArray *array=dataForSection.allKeys;

cell.textLabel.text = [[dataForSection allKeys] objectAtIndex:row];    
cell.detailTextLabel.text=[dataForSection valueForKey:[array objectAtIndex:indexPath.row]];

   return cell;     
 }

这段代码工作得很好如果我把更少的数据说10Array带有51个值...但是当我拿更多...屏幕显示像这样

Answer 1

我现在看到问题所在。你的索引选择太大了。

您可以通过删除sectionIndexTitlesForTableView方法来删除它。

如果你真的想要这个，你可以将所有字符串格式化为不大于几个字符，如：

-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
    NSMutableArray *shorterArray = [[NSMutableArray alloc]init];
    for( NSString *sectionTitle in self.mySections ){
        NSString *shortSectionTitle;
        if( sectionTitle.length > 4 ){
            shortSectionTitle = [NSString stringWithFormat:@"%@..", [sectionTitle substringToIndex:4]];
        } else {
            shortSectionTitle = sectionTitle;
        }
        [shorterArray addObject:shortSectionTitle];
    }
    return shorterArray;
}

Answer 2

NSDictionary *dataForSection = [self.mySections objectAtIndex:section];
NSArray *array=dataForSection.allKeys;

cell.textLabel.text = [array objectAtIndex:row];    
cell.detailTextLabel.text=[dataForSection objectForKey:[array objectAtIndex:row]];

Answer 3

尝试删除if（cell == nil）{}条件。即声明，cell = [[[UITableViewCell alloc] initWithStyle：UITableViewCellStyleValue1 reuseIdentifier：CellIdentifier] autorelease];外面是括号。

来自Plist的UItableView数据
