I have a split view app, created by adding a Split View Controller to a storyboard. I have a table view that is supposed to be grouped, with the rounded corners and gray background, but it's showing up plain style. I initialize the view in the app delegate like this:
self.dateController = [[DateViewController alloc] initWithStyle: UITableViewStyleGrouped];
Where DateViewController is my custom TableViewController class. Here's the relative code in DateViewController.m:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
[self.view setFrame: CGRectMake( 0, 260, 768, 764 )];
toolbar = [[UIToolbar alloc] initWithFrame: CGRectMake( 0, 0, 768, 44 )];
[self.view addSubview: toolbar];
}
return self;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 2;
}
- (NSInteger) tableView: (UITableView *) tableView numberOfRowsInSection: (NSInteger) section {
return 3;
}
What could be causing my table view not to be grouped? Thanks!
Finally found the answer! I was overriding the wrong init function. I used this code:
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:UITableViewStyleGrouped];
if (self) {
}
return self;
}
And now it works!

My code is:
- (instancetype)init {
self = [super initWithNibName:nil bundle:nil];
if (self) {
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height - 20)
style:UITableViewStylePlain];
for (int i = 0; i < 10; i++) {
[[LHItemSharedStore sharedStore] createItem];
}
}
return self;
}
- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
return [self init];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.tableView reloadData];
}
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.view addSubview:self.tableView];
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"UITableViewCell"];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [[[LHItemSharedStore sharedStore] items]count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"UITableViewCell" forIndexPath:indexPath];
cell.textLabel.text = #"test";
return cell;
}
As the code show, the datasource methods are not called. but when I put
[self.view addSubView:self.tableView];
In viewWillAppear, the methods can be called correctly, also works when I change [self.view addSubView:self.tableView]; to self.view = self.tableView;
The problem with your code is, that init is probably called after viewDidLoad , thus your table view is still nil when your setting the delegates.
problem solved!
seems that i use self.view.fram in my init method, then loadview is called, then call viewDidLoad, in viewDidLoad the init process of _tableView is not end, so _tableView is nil. if I set self.view = self.tableView in viewDidLoad, it will be called util self.tableView is not nil.
benifit i get it is that put view init into viewDidLoad.
I created MyCustomView which has two labels. One at left and one with right align and at right. It has about 30px height (it's not important). I connect it to xib and it works. In .xib I set main view width to 400px and set autolayout constraints for labels.
Now the problem. When I added to my controller in IB with UIView and set class to MyCustomView I see left label but right label is out of screen. I set constraints right but It doesn't work. When I tried to resize MyCustomView in .xib by mouse and moving with edges it's okay but when I set width value "manually" in right column it doesn't layout right (it doesn't change at all). Where is the problem? How can I fix this?
#implementation MyCustomView
- (id)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if (self) {
[self commonInit];
}
return self;
}
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self commonInit];
}
return self;
}
- (void)commonInit
{
self.backgroundColor = [UIColor clearColor];
self.view = [[[NSBundle mainBundle] loadNibNamed:#"MyCustomView"
owner:self
options:nil] firstObject];
[self addSubview:self.view];
//self.translatesAutoresizingMaskIntoConstraints = NO;
}
- (void)awakeFromNib {
[super awakeFromNib];
//[self setNeedsUpdateConstraints];
//[self setNeedsLayout];
}
#end
As you can see in comments I tried some ways but nothing helped.

The purpose is to implement a fixed search bar just like Contacts in iOS7.
I have a view controller called SearchViewController inherited from UIViewController.
And I add a searchBar and a tableView as its navigationController.view's subView.
But since searchBar and tableView are separated, when I start to search, no dim effect on tableView and result table view is shown in correctly.
I just want it behaves just like Contacts app.
Here is my code:
SearchViewController.h
#import <UIKit/UIKit.h>
#class UWTabBarController;
#class InfoSessionModel;
#interface SearchViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate>
SearchViewController.m
#import "SearchViewController.h"
#interface SearchViewController ()
#property (nonatomic, strong) UISearchBar *searchBar;
#property (nonatomic, strong) UISearchDisplayController *searchController;
#property (nonatomic, strong) UITableView *tableView;
#property (nonatomic, strong) NSArray *data;
#end
#implementation SearchViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// initiate search bar
NSInteger statusBarHeight = 20;
NSInteger navigationBarHeight = self.navigationController.navigationBar.frame.size.height;
_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, statusBarHeight + navigationBarHeight, 320, 44)];
// _searchBar.tintColor = [UIColor clearColor];
_searchBar.delegate = self;
_searchBar.barStyle = UIBarStyleDefault;
//NSMutableArray *scopeTitles = [[NSMutableArray alloc] initWithObjects:#"Employer", #"Program", #"Note", nil];
_searchBar.scopeButtonTitles = [[NSArray alloc] initWithObjects:#"Employer", #"Program", #"Note", nil];//[#"Employer|Program|Note" componentsSeparatedByString:#"|"];
// initiate search bar controller
_searchController = [[UISearchDisplayController alloc] initWithSearchBar:_searchBar contentsController:self];
_searchController.delegate = self;
_searchController.searchResultsDataSource = self;
_searchController.searchResultsDelegate = self;
// initiate table view
_tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, statusBarHeight + navigationBarHeight, 320, [UIScreen mainScreen].bounds.size.height - statusBarHeight - navigationBarHeight)];
[_tableView setContentInset:UIEdgeInsetsMake(_searchBar.frame.size.height, 0, _tabBarController.tabBar.frame.size.height, 0)];
_tableView.delegate = self;
_tableView.dataSource = self;
[_tableView registerClass:[InfoSessionCell class] forCellReuseIdentifier:#"InfoSessionCell"];
[_tableView registerClass:[LoadingCell class] forCellReuseIdentifier:#"LoadingCell"];
[self.navigationController.view addSubview:_tableView];
[self.navigationController.view addSubview:_searchBar];

This is the effects of my code:
All right, my problem is caused by my misunderstanding of views and navigationController's views.
In view did load method:
before is:
[self.navigationController.view addSubview:_tableView];
[self.navigationController.view addSubview:_searchBar];
but should be:
[self.view addSubview:_tableView];
[self.view addSubview:_searchBar];
In this way, the original table view and result table view will show correctly.
And other things are moving search bar up and down, these things should be done through UISearchBar delegate protocol methods and UISearchDisplayController delegate protocol methods.
This is a right way to implement a fixed searchBar and tableView bellow it.

self.title = #"Article view";
NSLog(#"count = %d",[self.tabBarController.tabBar.items count]);
}
return self;
}
//How can i make the first tabbar item title "Article View" to the Center without adding any //image to the tabbaritem ?
// similar to the below tabbar items screenshot.

Thanks in advance.
Replace the initWithNibName method
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = #"Article view";
self.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -5, 0);
NSLog(#"count = %d",[self.tabBarController.tabBar.items count]);
}
return self;
}
self.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -5, 0); this line here adjusts the position of the image for the tabBarItem in the manner :
Shift the image in x-direction '+5' and in y-direction '-5' from the
default position.
Play with UIEdgeInsetsMake and have fun. Cheers.
I'm setting the backgroundColor of my UITableViewCell like this:
cell.backgroundColor = [UIColor colorWithPatternImage:
[UIImage imageNamed:#"background.png"]];
It looks fine except for the "end caps" of the cell. The end caps (where the rounded corners start) are colored differently like the middle portion of the cell. Do I need to provide images for the end caps too?
not really sure what the end caps are. but i would say if ur using an image for your cell it should take up the whole cell. and you should be defining the size of your cells at that point. see layout subviews below for what i mean
