I am new to iphone development.I have displayed the text in the header label.Now i want to align the text to center. I using the following code
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(10.0, 0.0,300.0,44.0)];
UILabel * headerLabel = [[UILabel alloc] initWithFrame:CGRectZero];
headerLabel.backgroundColor = [UIColor brownColor];
headerLabel.textColor = [UIColor whiteColor];
headerLabel.highlightedTextColor = [UIColor whiteColor];
headerLabel.font = [UIFont boldSystemFontOfSize:15];
headerLabel.frame = CGRectMake(0.0, 0.0, 500.0, 22.0);
headerLabel.text = #"Hello"; //
[customView addSubview:headerLabel];
return customView;
}
"hello" should be displayed at the center of the header label.Please help me out.Thanks.
Try this:
headerLabel.textAlignment = UITextAlignmentCenter;

I am currently creating my own custom section headers but I have never dont any text editing via code.. and my new method that I am using to populate my custom header is doing some weird things as shown below
I would like to change the text to white and be slightly bolder and also make the white background transparent..
this is the code I am using to do this
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)];
[headerView setBackgroundColor:[UIColor grayColor]];
// Add the label
UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.5, 20, 20)];
// do whatever headerLabel configuration you want here
headerLabel.text = [self tableView:tableView titleForHeaderInSection:section];
[headerView addSubview:headerLabel];
// Return the headerView
return headerView;
}
I have tried this
[headerLabel.backgroundColor:[UIColor clearColor]];
etc but its not working :(
I would like to change the text to white...
UILabel's textColor property is your friend here.
And slightly bolder...
No problem! headerLabel.font = [UIFont boldSystemFontOfSize:mySize];
And make a white transparent background.
Whoa, whoa, that is the worst setter syntax ive ever seen!!! My lord, myLabel.backgroundColor is a getter, change:
[headerLabel.backgroundColor:[UIColor clearColor]];
to:
[headerLabel setBackgroundColor:[UIColor clearColor]];
Lucky for you, using your syntax would have just sent a message to nil, which is defaulting the background color of your label to white.
Use following code...
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UILabel *headername = [[UILabel alloc]initWithFrame:CGRectMake(20, 5, 270, 34)];
headername.backgroundColor = [UIColor clearColor];
headername.textColor = [UIColor blackColor];
if(section == 0)
{
headername.text = #"Name that u wish";
}
else
{
headername.text = #"Name that u wish";
}
UIView *headerView = [[UIView alloc] init];
UIImageView *tempimage = [[UIImageView alloc]initWithFrame:CGRectMake(10, 5, 300,34)];
tempimage.image = [UIImage imageNamed:#"whitebackground.png"];
[headerView addSubview:tempimage];
[headerView addSubview:headername];
return headerView;
}
Hope, this will help you...chill
all i have done to get the customized header in table is as following and it is working fine for me
UIView *containerView =
[[[UIView alloc]
initWithFrame:CGRectMake(0, 0, 300, 60)]
autorelease];
UILabel *headerLabel =
[[[UILabel alloc]
initWithFrame:CGRectMake(10, 20, 300, 40)]
autorelease];
headerLabel.text = NSLocalizedString(#"Header for the table", #"");
headerLabel.textColor = [UIColor whiteColor];
headerLabel.shadowColor = [UIColor blackColor];
headerLabel.shadowOffset = CGSizeMake(0, 1);
headerLabel.font = [UIFont boldSystemFontOfSize:22];
headerLabel.backgroundColor = [UIColor clearColor];
[containerView addSubview:headerLabel];
self.tableView.tableHeaderView = containerView;
i just put it in viewDidLoad: method
I know this is a noob question but ...I have these labels on a tableview, but the text is completely squished to the left. I want to add a bit of padding. How do I go about it?
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(10,0,300,60)] autorelease];
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
headerLabel.backgroundColor = [UIColor colorWithHexString:[[_months objectAtIndex:section] objectForKey:#"color"]];
headerLabel.font = [UIFont boldSystemFontOfSize:18];
headerLabel.frame = CGRectMake(0,0,400,30);
headerLabel.text = [[_months objectAtIndex:section] objectForKey:#"name"];
headerLabel.textColor = [UIColor whiteColor];
[customView addSubview:headerLabel];
return customView;
}
any help is much appreciated! Thanks!
For a full list of available solutions, see this answer: UILabel text margin
The most flexible approach to add padding to UILabel is to subclass UILabel and add an edgeInsets property. You then set the desired insets and the label will be drawn accordingly.
OSLabel.h
#import <UIKit/UIKit.h>
#interface OSLabel : UILabel
#property (nonatomic, assign) UIEdgeInsets edgeInsets;
#end
OSLabel.m
#import "OSLabel.h"
#implementation OSLabel
- (id)initWithFrame:(CGRect)frame{
self = [super initWithFrame:frame];
if (self) {
self.edgeInsets = UIEdgeInsetsMake(0, 0, 0, 0);
}
return self;
}
- (void)drawTextInRect:(CGRect)rect {
[super drawTextInRect:UIEdgeInsetsInsetRect(rect, self.edgeInsets)];
}
#end
you can simple add white space at the begin of you text;
[NSString stringWithFormat:#" %#",text];
It is 'evil' way to add 'padding', but it may help.
I found a better way to do this:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
CGRect frame = CGRectMake(0, 0, 320, 25);
UIView *customView = [[UIView alloc] initWithFrame:frame];
UILabel *sectionTitle = [[UILabel alloc] init];
[customView addSubview:sectionTitle];
customView.backgroundColor = [UIColor redColor];
frame.origin.x = 10; //move the frame over..this adds the padding!
frame.size.width = self.view.bounds.size.width - frame.origin.x;
sectionTitle.frame = frame;
sectionTitle.text = #"text";
sectionTitle.font = [UIFont boldSystemFontOfSize:17];
sectionTitle.backgroundColor = [UIColor clearColor];
sectionTitle.textColor = [UIColor whiteColor];
[sectionTitle release];
tableView.allowsSelection = NO;
return [customView autorelease];
}
Set the backgroundColor on the customView also
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
CGRect frame = tableView.bounds;
frame.size.height = HEADER_HEIGHT;
UIView* customView = [[[UIView alloc] initWithFrame:frame] autorelease];
customView.backgroundColor = [UIColor redColor];
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:CGRectInset(frame, LABEL_PADDING, 0)] autorelease];
// Orientation support
headerLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
headerLabel.backgroundColor = [UIColor redColor];
headerLabel.font = [UIFont boldSystemFontOfSize:18];
headerLabel.text = #"My Text Label";
headerLabel.textColor = [UIColor whiteColor];
[customView addSubview:headerLabel];
return customView;
}
Try not to hardcode magic numbers: (add these to top of file)
#define HEADER_HEIGHT 60.0f
#define LABEL_PADDING 10.0f
Should give this
Try the following & play around with the padding etc.
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
CGFloat headerHeight = 60, padding = 10;
UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(0,0,320,headerHeight)] autorelease];
customView.backgroundColor = [UIColor colorWithHexString:[[_months objectAtIndex:section] objectForKey:#"color"]];
CGRect frame = CGRectMake(padding,padding,320 - 2*padding,headerHeight-2*padding);
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:frame] autorelease];
headerLabel.font = [UIFont boldSystemFontOfSize:18];
headerLabel.backgroundColor = [UIColor clearColor];
headerLabel.text = [[_months objectAtIndex:section] objectForKey:#"name"];
headerLabel.textColor = [UIColor whiteColor];
[customView addSubview:headerLabel];
return customView;
}
You can create a subclass of UILabel and override intrinsicContentSize and - (CGSize)sizeThatFits:(CGSize)size:
- (CGSize) intrinsicContentSize
{
CGSize parentSize = [super intrinsicContentSize];
parentSize.width += 2*PADDING_VALUE;
return parentSize;
}
- (CGSize)sizeThatFits:(CGSize)size
{
CGSize parentSize = [super sizeThatFits:size];
parentSize.width += 2*PADDING_VALUE;
return parentSize;
}
True, it's a bit inexact and hackish, but you could always add a space in front of the month name like this:
headerLabel.text = [NSString stringWithFormat:#" %#",
[[_months objectAtIndex:section] objectForKey:#"name"]];
You could use a UITextView instead. I did this in Cocoa but I'm pretty sure it translates to UITextView:
NSTextView *headerLabel = [[[NSTextView alloc] initWithFrame:NSMakeRect(20.0, 20.0, 400.0, 20.0)] autorelease];
[headerLabel setBackgroundColor: [NSColor redColor]];
[headerLabel setString: #"Testing Stuff"];
[headerLabel setTextColor: [NSColor whiteColor]];
NSSize txtPadding;
txtPadding.width = 20.0;
txtPadding.height = 0.0;
[headerLabel setTextContainerInset:txtPadding];
[[mainWin contentView] addSubview:headerLabel];
I have a grouped UITableView. I am trying to make a custom UITableViewCell background:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.contentView.opaque = YES;
self.contentView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"rowbg#2x"]];
//Change Indicator
CGRect rect;
rect = CGRectMake(0, 0, 10, 50);
changeImageIndicator = [[UIImageView alloc] initWithFrame:rect];
[self.contentView addSubview: changeImageIndicator];
//Symbol
rect = CGRectMake(10, 10, 200, 20);
symbolLabel = [[UILabel alloc] initWithFrame:rect];
symbolLabel.textAlignment = UITextAlignmentLeft;
symbolLabel.font = [UIFont fontWithName:#"Arial" size:22];
symbolLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
symbolLabel.backgroundColor = [UIColor clearColor];
[self.contentView addSubview: symbolLabel];
//Company
rect = CGRectMake(10, 30, 180, 20);
companyLabel = [[UILabel alloc] initWithFrame:rect];
companyLabel.textAlignment = UITextAlignmentLeft;
companyLabel.font = [UIFont fontWithName:#"Arial" size:13];
companyLabel.adjustsFontSizeToFitWidth = YES;
companyLabel.minimumFontSize = 10.0;
companyLabel.backgroundColor = [UIColor clearColor];
companyLabel.textColor = [UIColor colorWithRed:118.0/255.0 green:118.0/255.0 blue:118.0/255.0 alpha:1.0];
[self.contentView addSubview: companyLabel];
//Price
rect = CGRectMake(190, 10, 100, 20);
priceLabel = [[UILabel alloc] initWithFrame:rect];
priceLabel.textAlignment = UITextAlignmentRight;
priceLabel.font = [UIFont fontWithName:#"Arial" size:20];
priceLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
priceLabel.backgroundColor = [UIColor clearColor];
[self.contentView addSubview: priceLabel];
//Change
rect = CGRectMake(190, 30, 100, 20);
changeLabel = [[UILabel alloc] initWithFrame:rect];
changeLabel.textAlignment = UITextAlignmentRight;
changeLabel.font = [UIFont fontWithName:#"Arial" size:15];
changeLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
changeLabel.adjustsFontSizeToFitWidth = YES;
changeLabel.backgroundColor = [UIColor clearColor];
changeLabel.minimumFontSize = 10.0; //adjust to preference obviously
[self.contentView addSubview: changeLabel];
}
return self;
}
The background color bleeds past the rounded corners. See image:
How can I make this not bleed?
This works for iOS 3.0 and later:
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = [UIColor redColor];
}
What about self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; ?
This worked for me when nothing else did. Set the background color in IB to the grouped Table view color (default). Then in code, set the color to clearColor. I also have the cells marked opaque=NO and clearsContextBeforeDrawing=NO, but those settings alone didn't change anything until I added the clearColor by code – Bdebeez
self.contentView.superview.opaque = YES;
self.contentView.superview.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"rowbg#2x"]];
Have you tried setting the backgroundColor of the backgroundView rather than the contentView?
I had to create a rounded top, middle and button graphic image and set it to the background view of the cell depending on which row it is.
Set the cell background color in the tableView:cellForRowAtIndexPath:
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"Gradient.png"]];
Im currently using the code below to render the view for my sectioned tableView
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
headerView.backgroundColor = [UIColor colorWithRed:30/255 green:30/255 blue:30/255 alpha:1.0];
headerView.layer.masksToBounds = NO;
headerView.layer.shadowOffset = CGSizeMake(0, 0);
headerView.layer.shadowRadius = 3;
headerView.layer.shadowOpacity = 0.5;
headerView.layer.shouldRasterize = YES;
UIBezierPath *path = [UIBezierPath bezierPathWithRect:CGRectMake(0, headerView.frame.size.height, headerView.frame.size.width, 3)];
headerView.layer.shadowPath = path.CGPath;
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(12, 7, tableView.bounds.size.width - 10, 20)] autorelease];
label.font = [UIFont boldSystemFontOfSize:16];
label.text = header;
label.textColor = [UIColor whiteColor];
label.shadowColor = [UIColor blackColor];
label.shadowOffset = CGSizeMake(0.0f, 1.0f);
label.backgroundColor = [UIColor colorWithRed:30/255 green:30/255 blue:30/255 alpha:1.0];
[headerView addSubview:label];
return headerView;
}
For some reason though the text is being mangled a bit and a little distorted? I have narrowed it down to the effects i am putting on the layer although im not sure why its doing it?
I see you are setting shouldRasterize to YES. Does setting the rasterization scale help? This would only be needed if you are using an iPhone 4.
[[headerView layer] setRasterizationScale:[[UIScreen mainScreen] scale]];
I'm using UINavigationItem's titleView property to set a custom UILabel with my desired font size/color. Here's my code:
self.headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 400.0, 44.0)];
self.headerLabel.textAlignment = UITextAlignmentCenter;
self.headerLabel.backgroundColor = [UIColor clearColor];
self.headerLabel.font = [UIFont boldSystemFontOfSize:20.0];
self.headerLabel.textColor = [UIColor colorWithRed:0.259 green:0.280 blue:0.312 alpha:1.0];
self.navigationItem.titleView = self.headerLabel;
In the navigation bar I also have a left bar button. The result is: the text isn't properly centered. I've tried setting the x origin of the label, but this has no effect.
In stead of initWithFrame just use init and put [self.headerLabel sizeToFit] after your last line of code.
If you make the headerLabel a subview of the titleView, you can then set headerLabel's frame to control where it goes within the titleView.
The way you are doing it now, you don't have that control. I think the OS chooses the titleView's frame for you based on the space available.
Hope this helps!
I've used custom title labels for my nav bars in every app I have in the app store. I've tested many different ways of doing so and by far the easiest way to use a custom label in a navigation bar is to completely ignore titleView and insert your label directly into navigationController.view.
With this approach, it's easy to have the title label's frame always match the navigationBar's frame -- even if you are using a custom navBar with a non-standard size.
- (void)viewDidLoad {
[self.navigationController.view addSubview:self.titleLabel];
[super viewDidLoad];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (void)didRotateFromInterfaceOrientation:
(UIInterfaceOrientation)fromInterfaceOrientation {
[self frameTitleLabel];
}
- (UILabel *) titleLabel {
if (!titleLabel) {
titleLabel = [[UILabel alloc]
initWithFrame:self.navigationController.navigationBar.frame];
titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:18];
titleLabel.text = NSLocalizedString(#"Custom Title", nil);
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
}
return titleLabel;
}
- (void) frameTitleLabel {
self.titleLabel.frame = self.navigationController.navigationBar.frame;
}
The one caveat to this approach is that your title can flow over the top of any buttons you have in the navBar if you aren't careful and set the title to be too long. But, IMO, that is a lot less problematical to deal with than 1) The title not centering correctly when you have a rightBarButton or 2) The title not appearing if you have a leftBarButton.
I have a same problem; I just somehow solved this issue by calculating the title length and set the label frame width accordingly. Although this is not a perfect one but can be manageable. Here is the code.
label = [[UILabel alloc] init];
label.backgroundColor = [UIColor clearColor];
label.font = [ UIFont fontWithName: #"XXII DIRTY-ARMY" size: 32.0 ];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.0f];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor orangeColor];
//label.text=categoryTitle;
CGFloat verticalOffset = 2;
NSString *reqSysVer = #"5.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
{
if (categoryTitle.length > 8)
{
label.frame = CGRectMake(0, 0, 300, 44);
}else {
label.frame = CGRectMake(0, 0, 80, 44);
}
self.navigationItem.titleView = label;
self.navigationItem.title=label.text;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setTintColor:[UIColor newBrownLight]];
}
Just calculate exact frame size needed and align to left:
UIFont* font = [UIFont fontWithName:#"Bitsumishi" size:20];
CGSize maximumLabelSize = CGSizeMake(296,9999);
CGSize expectedLabelSize = [title sizeWithFont:font constrainedToSize:maximumLabelSize lineBreakMode:UILineBreakModeCharacterWrap];
CGRect frame = CGRectMake(0, 0, expectedLabelSize.width, expectedLabelSize.height);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.font = font;
label.textAlignment = UITextAlignmentLeft;
label.text = title;
self.titleView = label;
UIView *vw = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
lbl.text = #"Home";
lbl.textAlignment = UITextAlignmentCenter;
lbl.backgroundColor = [UIColor clearColor];
lbl.textColor = [UIColor whiteColor];
lbl.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:20];
lbl.shadowColor = [UIColor blackColor];
lbl.shadowOffset = CGSizeMake(0,1);
self.navigationItem.titleView = vw;
[self.navigationItem.titleView addSubview:lbl];
What worked for me was to update the titleView frame in the viewDidAppear method.
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
UIView *titleView = self.navigationItem.titleView;
CGRect navBarFrame = self.navigationController.navigationBar.frame;
[titleView setFrame:CGRectMake((CGRectGetWidth(navBarFrame) - TitleWidth) / 2, (CGRectGetHeight(navBarFrame) - TitleHeight) / 2, TitleWidth, TitleHeight)];
}
