表格视图的索引列表显示点iOS 5+ [英] Indexed list for table view shows dot iOS 5+
问题描述
在我的应用程序中,我在表格视图中显示带有索引列表的联系人。我正在显示索引列表如下:
In my application I am displaying contacts in table view with indexed list. I am displaying indexed list as follow:
static NSString *letters = @"abcdefghijklmnopqrstuvwxyz#";
-(void)getAllUserInfoUsingBlock:(lclResultsArray) block
{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
NSMutableArray *allUserInfoArray = [[NSMutableArray alloc]init];
NSLog(@"[letters length]:- %d",[letters length]);
for (int i = 0; i < [letters length]; i++ ) {
NSMutableDictionary *row = [[NSMutableDictionary alloc] init];
char currentLetter[2] = { toupper([letters characterAtIndex:i]), '\0'};
NSString *str=[NSString stringWithCString:currentLetter encoding:NSASCIIStringEncoding];
NSMutableArray *words = nil;
NSLog(@"Value of i:- %d:: Letter:- %@",i,str);
if (i<[letters length]) {
words = [self getUserInfoByStartingCharOfLastName:str isForEmptyValue:NO];
}
else {
// Get users where name is empty
words = [self getUserInfoByStartingCharOfLastName:@"" isForEmptyValue:YES];
}
NSLog(@"Count for %@ :- %d",str,words.count);
[row setValue:str forKey:@"sectionTitle"];
[row setValue:words forKey:@"sectionRows"];
[allUserInfoArray addObject:row];
}
dispatch_async(dispatch_get_main_queue(), ^{
for (NSDictionary *dict in allUserInfoArray) {
NSLog(@"Array count:- %d",[[dict objectForKey:@"sectionRows"]count]);
}
block(allUserInfoArray,nil);
});
});
}
- (NSString *)tableView:(UITableView *)aTableView titleForHeaderInSection:(NSInteger)section
{
if (aTableView != self.searchDisplayController.searchResultsTableView){
NSMutableDictionary *sections=[self.contactsArray objectAtIndex:section];
NSString * sectionTitle= [sections objectForKey:@"sectionTitle"];
return sectionTitle;
}
return nil;
}
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
if (tableView != self.searchDisplayController.searchResultsTableView){
NSMutableDictionary *sections=[self.contactsArray objectAtIndex:index];
NSString * sectionTitle= [sections objectForKey:@"sectionTitle"];
return [self.indices indexOfObject:sectionTitle];
}
return 0;
}
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
if (tableView != self.searchDisplayController.searchResultsTableView){
return [self.contactsArray valueForKey:@"sectionTitle"];
}
return nil;
}
但它显示如下图所示
尽可能在第一张图片中看到它显示的ACE .... VXZ#它在每个字符后显示交替的点(。)。但是如第二张图片所示,它显示ABC的表格的正确的headet标题.... XYZ#
As you can see in first image its displaying A.C.E .... V.X.Z# Its displaying alternate dots(.) after every character.But as shown in second image its dispalying correct headet title for table from ABC....XYZ#
我的实施有什么问题?
推荐答案
索引列表中字符之间的替代点取决于显示indexedlist的高度。如果我们可以增加tableSize。它将自动显示整个字符。
Alternative dots between characters in indexed list depends upon display height of that indexedlist.if we can increase the tableSize .it will be automatically display whole characters.
