How to indent only UITableViewCell content not the separator? - ios

If I use this code to indent from left, everything is indented (separator + content)
table.contentInset = UIEdgeInsetsMake(0, 20, 0, 0);
Same if I use this:
cell.layoutMargins = UIEdgeInsetsMake(0, 20, 0, 0);
This doesn't help neither, because it doesn't move the image.
cell.indentationLevel = 10;

You can use a CustomTableCell to get what you want:
At first, in ViewController:
#import "ViewController.h"
#import "MyTableCell.h"
#interface ViewController ()
#property UITableView *tableView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
_tableView.separatorStyle = UITableViewCellSelectionStyleNone;
_tableView.backgroundColor = [UIColor grayColor];
_tableView.dataSource = self;
_tableView.delegate = self;
[self.view addSubview:_tableView];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 20;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
MyTableCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MyCell"];
if (nil == cell) {
cell = [[MyTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"MyCell"];
}
//Update data for cell
return cell;
}
#end
This is MyTableCell.h:
#import "MyTableCell.h"
#interface MyTableCell()
#property UIView *containerView;
#property UIView *separationLine;
#end
#implementation MyTableCell
-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
_containerView = [[UIView alloc] init];
_containerView.backgroundColor = [UIColor redColor];
[self addSubview:_containerView];
_separationLine = [[UIView alloc] init];
_separationLine.backgroundColor = [UIColor blackColor];
[self addSubview:_separationLine];
return self;
}
-(void)layoutSubviews{
_containerView.frame = CGRectMake(20, 0, self.frame.size.width-20, self.frame.size.height-1);
_separationLine.frame = CGRectMake(10, self.frame.size.height-1, self.frame.size.width-10, 1);
}
#end
And this is the screenshot for the code:
You can modify the code in "layoutSubviews" as your wish.
Hope it can help you.

Imageview is not showing up in a programmatically created collectionview

I am having a hard time figuring out why cell.imageview property doesn't show me image below. UIImage is not nil, cells are created, if I assign a background to cell, it is displayed which proves I am creating collectionview and my cells correctly. I programmatically create my collectionview and don't use any IB or interface builder. I have done this lots of times before, but I am really scratching my head with this one.
Thanks in advance.

You missed to add the cell's imageView as a it's subview.
So in cell's initWithFrame
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.imageView = [[UIImageView alloc] initWithFrame:self.bounds];
//Add imageView as subview
[self addSubview:self.imageView];
NSLog(#"self.bounds is %#", NSStringFromCGRect(self.bounds));
}
return self;

How to insert a button on the bottom of every UITableView section?

I currently have a UITableView within my MatchCenterViewController, and I designed it to load up 10 rows for every section, but only show the first 4 by making the heightForRowAtIndexPath return a value of 0 for the rest. What I want to do is have a button on the bottom of every section that when pressed, will reload the data and show 10 instead of 4 for just that specific section.
I've started working on the framework for what happens when the button is pressed, I'm just having trouble with the syntax for rendering the button on the bottom and showing 10 rows for only that respective section. Here's how I have my UITableView laid out so far:
MatchCenterViewController.h:

for this functionality you can either use special UITableviewCell or a footerView of UITableView
You can use property tableFooterView.
Below is how I use in showing load more option
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 65)];
v.backgroundColor = [UIColor clearColor];
int mySiz = 0;
// keep counter how many times load more is pressed.. initial is 0 (this is like index)
mySiz = [startNumberLabel.text intValue]+1;
// i have 15 bcz my index size is 15.
if ([feeds count]>=(15*mySiz)) {
NSLog(#"showing button...");
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(10, 10, 296, 45)];
[button setBackgroundImage:[UIImage imageNamed:localize(#"loadmore")] forState:UIControlStateNormal];
[button addTarget:self action:#selector(loadMoreData:) forControlEvents:UIControlEventTouchUpInside];
[v addSubview:button];
mainTableView.tableFooterView = v;
} else {
mainTableView.tableFooterView = nil;
}
[mainTableView reloadData];
Now adjust code as per your necessity...
Ended up doing it like this:
// Create "more" button
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.backgroundColor = [UIColor whiteColor];
self.moreButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.moreButton.frame = CGRectMake(0, 0, 320, 44);
[self.moreButton setImage:[UIImage imageNamed:#"downarrow.png"] forState:UIControlStateNormal];
[self.moreButton addTarget:self action:#selector(moreButtonSelected:) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:self.moreButton];
return view;
}
// Load rest of items
- (void)moreButtonSelected:(id)sender {
if (_hasPressedShowMoreButton == NO){
self.hasPressedShowMoreButton = YES;
}
else if (_hasPressedShowMoreButton == YES){
self.hasPressedShowMoreButton = NO;
}
[self.matchCenter reloadData];
}

iOS: Custom Cell Properties with Code and IB do not appear together

CustomCell.h
#interface CustomCell : UITableViewCell
//Properties created in Code, not via IB.
#property (nonatomic, strong) UILabel *labelUsername;
#property (nonatomic, strong) UIView *circle;
//Properties Created through IB by control+drag
#property (nonatomic, strong) UILabel *labelFirstName;
#property (nonatomic, strong) UILabel *labelLastName;
#end
CustomCell.m
#implementation CustomCell
-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
//Creating properties in code
self.circle = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 40.0f, 40.0f)];
[self.circle setBackgroundColor:[UIColor brownColor];
self.labelUsername = [[UILabel alloc] initWithFrame:CGRectMake(15, 20, 200.0f, 50.0f)];
self.labelUsername.textColor = [UIColor blackColor];
[self.contentView addSubview:self.labelUsername];
[self.contentView addSubview:self.circle];
}
return self;
}
tableView.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *customCellIdentifier = #"CustomCell";
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:customCellIdentifier];
if (cell == nil) {
cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:inviteCellIdentifier];
}
cell.labelFirstName.text = #"FirstName";
cell.labelLastName.text = #"LastName";
return cell;
}
The code above continued to show labelUsername and circle. However, the properties created using the IB (labelFirstName and labelLastName) did not appear.
So in tableView.m in viewDidLoad I registered the Nib with the following code:
- (void)viewDidLoad
{
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:#"CustomCell"
bundle:[NSBundle mainBundle]]
forCellReuseIdentifier:#"CustomCell"];
}
Now labelFirstName and labelLastName appear, but the properties created with code (labelUsername and circle) DO NOT appear.
How can I get all 4 properties to show?
Try this in CustomCell.m,
- (void)awakeFromNib
{
[super awakeFromNib];
self.circle = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 40.0f, 40.0f)];
[self.circle setBackgroundColor:[UIColor brownColor];
self.labelUsername = [[UILabel alloc] initWithFrame:CGRectMake(15, 20, 200.0f, 50.0f)];
self.labelUsername.textColor = [UIColor blackColor];
[self.contentView addSubview:self.labelUsername];
[self.contentView addSubview:self.circle];
}
Try this after self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
NSArray *views = [[NSBundle mainBundle]loadNibNamed:#"yourNibName" owner:self options:NULL];
[self addSubview:[views lastObject]];

tableview doesn't see the tableview view for header in section method

I was trying to create a custom section for my tableview.Tableview itself works fine, but for some reason, compiler skips,
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
delegate method, and i tried what is written on the reference , and this . I also added the tableView:heightForHeaderInSection: method as it suggests in reference page but for some reason it just doesn't read these methods. Obviously, I am doing something wrong. If someone can point my mistake out, I would appreciate. Thank you in advance.

You have a typo in the viewDidLoad method:

self.profileTableView.dataSource = self;
One of these should be delegate.

issue with using multiple cell types in uitableview

I am using this code for multiple cell types in a UITableView
The problem is that the cell text is invisible. The code for cellForRowAtIndexPath as well as the cell class code is given below:
code:
static NSString *kCellIdentifier = #"NewsViewControllerTableCell";
static NSString *kCellIdentifier2 = #"SubscribeCell";
if ((indexPath.row==0) && ([[NSUserDefaults standardUserDefaults] boolForKey:#"subscribeButtonOption"]))
{
SubscribeCell* cell = (SubscribeCell*)[tableView dequeueReusableCellWithIdentifier:kCellIdentifier2];
if (cell == nil) {
cell = [[[SubscribeCell alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 35.0) reuseIdentifier:kCellIdentifier2] autorelease];
cell.contentView.backgroundColor = kColorR53G53B53;
cell.subscribeLabel.font = kLucidaSansStdFontBold_14;
cell.subscribeLabel.textColor = [UIColor whiteColor];
}
cell.subscribeLabel.textColor=[UIColor redColor];
cell.subscribeLabel.text = #"+ SUBSCRIBE TO NEWSLETTER";
cell.selectedBackgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
cell.selectedBackgroundView.backgroundColor =kColorR53G53B53;
[cell setNeedsDisplay];
return cell;
}
else
{
//another cell
}
=========
header:
#import <UIKit/UIKit.h>
#interface SubscribeCell : UITableViewCell{
UILabel *subscribeLabel;
}
#property(nonatomic, retain) UILabel *subscribeLabel;
#end
and implementation class:
#import "SubscribeCell.h"
#implementation SubscribeCell
#synthesize subscribeLabel;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
subscribeLabel=[[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 323.0, 40.0)];
subscribeLabel.textColor=[UIColor whiteColor];
self.backgroundColor=kColorR53G53B53;
}
return self;
}
Check to see if subscribeLabel is nil. You're creating it in initWithNibName:bundle: but are initializing with initWithFrame:reuseIdentifier:, so it's not reaching your label creation code.
If I try to compile your code, I get an error message stating that UITableViewCell does not declare a method called 'initWithNibName: bundle:'. You should use the proper initialization method 'initWithStyle: reuseIdentifier:'. You also forget to add the subscribeLabel to the contentView of the cell.
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
subscribeLabel=[[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 323.0, 40.0)];
subscribeLabel.textColor=[UIColor whiteColor];
[self.contentView addSubview:subscribeLabel];
self.backgroundColor=kColorR53G53B53;
}
return self;
}
