UITableView setSeparatorInset does not work properly - ios

I am trying to have a custom inset for the separator in a UITableView. Here is my code for viewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
[self.tableView registerClass:[ChatTableCell class] forCellReuseIdentifier:#"ChatCell"];
[self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 65, 0, 0)];
}
The cell separator inset does not work properly as shown in the picture. It works for some cells and does not for others. What am I doing wrong here?
This is what my viewcontroller.m file looks like
#import "ChatListViewController.h"
#interface ChatListViewController ()
#end
#implementation ChatListViewController
- (id)initWithStyle:(UITableViewStyle)style {
//self = [super initWithStyle:style];
self = [super initWithStyle:UITableViewStylePlain];
if (self) {
self.parseClassName = kChatRoomClassKey;
self.paginationEnabled = YES;
self.pullToRefreshEnabled = YES;
self.objectsPerPage = 25;
//[self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 65, 0, 0)];
}
return self;
}
- (PFQuery *)queryForTable {
if (![PFUser currentUser]) {
PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];

After all my workaround , now fixed in both ios 7 and 8 tested.

I have made a ViewController and added a table view in it. Some data is populated in cells and then displayed.
When I run it, initially I don't see any data in my cells. But when the tableview is scrolled cells start showing the actual data. I don't understand what could be the reason. Any pointers please???
I want to dynamically resize my cells as data can be of random size. Data shows only after scrolling once.
This problem is related to using UITableViewAutomaticDimension and has been reported at other places as well. So this line of code, solved my problem:
-(void)viewDidAppear:(BOOL)animated {
[self.tableView reloadData];
}
This just reloads all the table sections and rows before displaying. So user does not experience blank rows. Refer: http://www.appcoda.com/self-sizing-cells/
You need to use reloadData in the main thread (viewDidLoad). You need to use
dispatch_async like the code below :
dispatch_async(dispatch_get_main_queue(), ^{
[self.mytable reloadData];
}
In setupTable, check sectionArray and orderedData to make sure they're not empty. Add an assertion in setupTable, e.g.,
sectionArray = [[SummaryModel sharedInstance] getTableSections:self.s_sendEnhancementServerDict];
orderedData = [[SummaryModel sharedInstance] getOrderedData:self.s_sendEnhancementServerDict];
NSAssert([sectionArray count] && [orderedData count], #"No data!"); // add this line
[self.bookingsTableView reloadData];

iOS Parse UISearchBar

I am new to iOS. I am making an app in which i am getting data from Parse back-end all are working fine.
I did UISearchbar and it works well. But when a search produces more than 6 results (main table have 6 rows, but I search for another Parse class) , this leads to an error.

Please help me! I can not solve the problem for several days. :'(
Try
dispatch_async(dispatch_get_main_queue(), ^{
[self.searchResults removeAllObjects];
[self.searchResults addObjectsFromArray:goodsList];
[self.searchController.searchResultsTableView reloadData];
});
to ensure editing your datasource and reloading your tablew view are done in the same dispatch queue.

Parse Pagination loadNextPage 2nd Page Loads Twice

In my Parse app, I have Pagination enabled, and for testing purposes, objects per page set to 5. When I run the app I get this in my TableView
1
2
3
4
5
Load More
After clicking Load More the entire table looks like:
1
2
3
4
5
6
7
8
9
10
6
7
8
9
10
Clicking Load More after this will add the set of 11-15 twice. What is going on?

Search textfield Results not selectable

I'm using UITextFields as my search bars. I had to do this because I have multiple inputs for people to search for. The search is working perfectly. In fact the text field is working better than a normal search bar memory wise. The only problem is that I cannot select the resulting cell. When I press the cell nothing at all happens. I even put a log statement in didselect and the cell is not even getting the action. Help please.

UISearchDisplayController displaying results parse

I have got fully working UISearchDisplayController implied in my UITableView made with Parse.com. Anyway when I put to search for, I always get only results starts with that letter. I want to display every data contains that letter.
For example: I put Om into my search and it searched me only : Oman and Ombudsman . I have in my UITableView also a cell named Community . You see this word also contains om but my search don`t display anything. It displays just words staring with these letters.
Can someone help me? Thank you.

Use - (void)whereKey:(NSString *)key containsString:(NSString *)substring instead of - (void)whereKey:(NSString *)key hasPrefix:(NSString *)prefix
-(void)filterResults:(NSString *)searchTerm {
PFQuery *query = [PFQuery queryWithClassName: #"Countries"];
[query whereKey:#"CountryTitle" containsString:searchTerm];
query.limit = 50;
[query findObjectsInBackgroundWithTarget:self selector:#selector(callbackWithResult:error:)];
}
if you use hasPrefix: then the search results will be elements starting with your search string.
