UILabel not align center on UINavigationBar in iPhone - iphone

I need to align UILabel text center on UINavigationBar. I have implemented all the steps but some how its not center Align. Below is code.
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
titleLabel.backgroundColor = [UIColor clearColor];
[titleLabel setTextColor:[UIColor whiteColor]];
self.titleLabel.text = title;
self.titleLabel.lineBreakMode = NSLineBreakByTruncatingMiddle;
self.titleLabel.adjustsFontSizeToFitWidth = NO;
self.titleLabel.adjustsLetterSpacingToFitWidth = NO;
self.titleLabel.textAlignment = NSTextAlignmentCenter;
[self.titleLabel sizeToFit];
float titlePadding = 60.0f;
self.titleLabel.left = titlePadding;
self.titleLabel.width = self.width - 2 * titlePadding;
self.titleLabel.top = ceilf(self.frame.size.height / 2 - self.titleLabel.frame.size.height / 2);
Please help me with this

Try This It will help
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = NSTextAlignmentCenter;
// ^-Use UITextAlignmentCenter for older SDKs.
label.textColor = [UIColor yellowColor]; // change this color
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"PageThreeTitle", #"");
[label sizeToFit];

You need to increase the content size of the scroll view its diffrent from its frame size if content size is more then frame size it will scroll.

How to do parameter passing for Creating N number or labels programmatically

I am doing an application where I am creating a LABELS programmatically..What my Requirement is I need to create some 10 LABELS programmatically, so only there Position and Text label changes. Instead of Writing the same function for every Label Thought of doing it By parameter passing, where only v need pass only the Label name and Position of the label...how to implement it?
//Below code shows creation of Labels With Different Names, instead I want to have one function and do parameter passing rather than creating a function for each label.
-(void)Vendorname
{
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(50,80,150,20)];

myLabel.text = #"Vendor Name";
[self.view addSubview:myLabel];
[myLabel release];
}
-(void)address

call the above method...
[self createLabel:#"label1" :frame];
try this one

Setting background color of grouped UITableViewCell

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"]];

UINavigationItem titleView position

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)];
}
