I am adding a UILabel to the tableHeaderView but for some reason it is left aligned.
self.messageLabel = [[UILabel alloc] initWithFrame:CGRectZero];
[self.messageLabel setText:#"Nothing to display!"];
[self.tableView setTableHeaderView:self.messageLabel];
[self.tableView.tableHeaderView setBackgroundColor:[UIColor blueColor]];
[self.tableView.tableHeaderView setFrame:CGRectMake(320/2, 480/2, 100, 20)];
[self.messageLabel setCenter:self.tableView.tableHeaderView.center];
[label setTextAlignment:UITextAlignmentCenter];

Is it possible to add rows and columns to an UITableview in iPhone as shown below?
Please help me, I'm new to iOS development.
I found the answer.
UIView *newView124=[[UIView alloc]initWithFrame:CGRectMake(224, 90, 2, 48)];
newView124.backgroundColor=[UIColor grayColor];
[cell addSubview:newView124];
//Initialize Label
NSLog(#"cell width: %f",cell.frame.size.width);
UILabel *lbl1 = [[UILabel alloc]initWithFrame:CGRectMake(0, 90, 100, 50)];
[lbl1 setFont:[UIFont fontWithName:#"FontName" size:12.0]];
[lbl1 setTextColor:[UIColor blackColor]];

I am developing one application for iphone and in that i have some issues regarding adding more then one UILabel in navigation bar at a specific position.
What i want is in following images
in above image there is one backbar button and one imageview as shown with arrow-mark. Other then that all white box is for difrent UILabels to show in navigation bar.
There is only one UIImageView in the navigation bar and one left bar button. Now problem is that i don't know how to add multiple UILabel in navigation bar at a specific position.
Till now what i have worked is to add only button and UIImageView with the right bar button array or left bar button array, but that only add items in sequnce.
So can anyone please guide me that how can anyone add UILabels or any other item at a specific position..
you can add Multiple UIlabel or Image as look like bellow image:-
this can do using bellow code you can change Label and imageView frame and put as your requirement
- (void)viewDidLoad
{
UIView *btn = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 60)];
UILabel *label;
label = [[UILabel alloc] initWithFrame:CGRectMake(5, 25, 200, 16)];
label.tag = 1;
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:16];
label.adjustsFontSizeToFitWidth = NO;
label.textAlignment = UITextAlignmentLeft;
label.textColor = [UIColor whiteColor];
label.text = #"My first lable";
label.highlightedTextColor = [UIColor whiteColor];
[btn addSubview:label];
[label release];
label = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 200, 16)];
label.tag = 2;
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:16];
label.adjustsFontSizeToFitWidth = NO;
label.textAlignment = UITextAlignmentRight;
label.textColor = [UIColor whiteColor];
label.text = #"second line";
label.highlightedTextColor = [UIColor whiteColor];
[btn addSubview:label];
[label release];
UIImageView *imgviw=[[UIImageView alloc]initWithFrame:CGRectMake(170, 10, 20, 20)];
imgviw.backgroundColor = [UIColor blackColor];
imgviw.image=[UIImage imageNamed:#"a59117c2eb511d911cbf62cf97a34d56.png"];
[btn addSubview:imgviw];
self.navigationItem.titleView = btn;
}
You can add subviews directly to the navigationBar -
UINavigationBar *navBar = navController.navigationBar;
[navBar addSubview: yourLabel];
yourLabel frame origin will be relative to the navigation bar
Try this code
UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
buttonContainer.backgroundColor = [UIColor clearColor];
UIButton *button0 = [UIButton buttonWithType:UIButtonTypeCustom];
[button0 setFrame: CGRectMake(160, 7 , 40, 30)];
[button0 setTitle:#"Sort" forState:UIControlStateNormal];
button0.titleLabel.font = [UIFont fontWithName:#"Helvetica" size:12];
[button0 setBackgroundImage:[UIImage imageNamed:#"Btn_Sort_Btn_Sort_Places.png"] forState:UIControlStateNormal];
[button0 addTarget:self action:#selector(sortAction) forControlEvents:UIControlEventTouchUpInside];
[button0 setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
self.navigationItem.titleView = buttonContainer;
UILabel *lbl_title = [[UILabel alloc] initWithFrame:CGRectMake(10, 0 , 140, 40)];
lbl_title.text = str_HeaderTitle;
lbl_title.textColor = [UIColor whiteColor];
lbl_title.font = [UIFont fontWithName:#"Helvetica-Bold" size:16];
lbl_title.backgroundColor = [UIColor clearColor];
lbl_title.textAlignment = NSTextAlignmentCenter;
[buttonContainer addSubview:lbl_title];
You can set an arbitrary view instead of a view controller's title:
myViewController.navigationItem.titleView = someView;
Note that most likely the view's frame will be restricted to make room for leftBarButtonItem and rightBarButtonItem.
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(50, 2, 20, 15)];
[label setBackgroundColor:[UIColor greenColor]];
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(40, 20, 150, 10)];
[imgView setBackgroundColor:[UIColor redColor]];
[[self.navigationController navigationBar] addSubview:label];
[self.navigationController.navigationBar addSubview:imgView];
Have a look at this piece of code. With some modifications it should solve your problem:
UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[imageButton setFrame:CGRectMake(15, 0, 57, 44)];
[imageButton setBackgroundImage:[UIImage imageNamed:#"someImage.png"] forState:UIControlStateNormal];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(140, 0, 250, 44)];
[titleLabel setText:#"some title"];
[titleLabel setBackgroundColor:[UIColor clearColor]];
[titleLabel setTextColor:[UIColor whiteColor]];
[titleLabel setFont:[UIFont boldSystemFontOfSize:20]];
[self.navigationController.navigationBar addSubview:imageButton];
[self.navigationController.navigationBar addSubview:titleLabel];
Just modify the values in the CGRectMake() to fit your needs.
viewController.m
-(void) viewDidLoad
{
[super viewDidLoad];
[self addScoreRowViewWithIndexLeft:(++i) andName:[scoreDict objectForKey:#"name"] andScore:[[scoreDict objectForKey:#"points"] integerValue]];
}
-(void) addScoreRowViewWithIndexLeft:(NSInteger)index andName: (NSString *)name andScore: (NSInteger)score {
UIView *scoreRowView = [[UIView alloc] initWithFrame:CGRectMake(128, 112 + index * 80, 280, 20)];
UILabel *indexLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 20, 20, 20)];
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(150, 20, 180, 20)];
UILabel *scoreLabel = [[UILabel alloc] initWithFrame:CGRectMake(330, 20, 50, 20)];
UIColor *color = [UIColor darkGrayColor];
[indexLabel setText:[#((int)index) stringValue]];
[indexLabel setFont:[UIFont fontWithName:#"DINAlternate-Bold" size:18]];
[indexLabel setTextColor:color];
[nameLabel setText:name];
[nameLabel setFont:[UIFont fontWithName:#"DINAlternate-Bold" size:18]];
[nameLabel setTextColor:color];
[scoreLabel setText:[#((int)score) stringValue]];
[scoreLabel setFont:[UIFont fontWithName:#"DINAlternate-Bold" size:18]];
[scoreLabel setTextColor:color];
[scoreRowView addSubview:indexLabel];
[scoreRowView addSubview:nameLabel];
[scoreRowView addSubview:scoreLabel];
[self.view addSubview:scoreRowView];
}
I added my ImageView in my Storyboard as a subview of my View.
When I delete the ImageView, everything is ok. I get displayed my other code generated subviews. But when I add the ImageView in my Storyboard, it's on top of my other subviews. If I give my ImageView an alpha of 0.3 I can see my subviews shining through.
What's wrong with my code? I also tried;
[self.view bringSubviewToFront:scoreRowView];
but it doesn't work.
What can I do?
Try to change zPosition of your ImageView and scoreRowView. You can do this this way:
Connect your ImageView with your ViewController
In bottom of ViewDidLoad add something like that:
yourImageView.layer.zPosition = 1;
scoreRowView.layer.zPosition = 2;
I'm suspecting that [self.view bringSubviewToFront:scoreRowView]; doesn't work because you invoke it in ViewDidLoad where view in not fully work. You can try to invoke it in e.g. ViewDidAppear and check if that will work.
I am trying to center a label and an image in a tableView Footer
I can't seem to make it work for both device iPhone and iPad
Right now it is centered on the iPhone but that's because I hardcoded it.
-(UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 50)];
[view setBackgroundColor:[UIColor clearColor]];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 15, self.view.bounds.size.width, 20)];
lbl.lineBreakMode = NSLineBreakByWordWrapping;
lbl.numberOfLines = 0;
[lbl setText:#"Powered By"];
[lbl setFont:[UIFont systemFontOfSize:10]];
[lbl setTextAlignment:NSTextAlignmentCenter];
[lbl setTextColor:[UIColor blackColor]];
District *school = [District new];
UIImageView * logoView = [[UIImageView alloc]initWithFrame:CGRectMake(50, 25, 150, 37.5)];
logoView.image = [UIImage imageNamed:#"Logo.png"];
[logoView autoresizingMask];
[view addSubview:logoView];
[view addSubview:lbl];
return view;
}
I would like to center this view, without hardcoding it. I tried taking the screen size and divide by 2.
It did not center, what is the right approach, please advise.
You need to set the view's autoresizingMask as needed.
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 50)];
[view setBackgroundColor:[UIColor clearColor]];
CGRect lblFrame = view.bounds;
lblFrame.origin.y = 15;
lblFrame.size.height = 20;
UILabel *lbl = [[UILabel alloc] initWithFrame:lblFrame];
lbl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
lbl.lineBreakMode = NSLineBreakByWordWrapping;
lbl.numberOfLines = 0;
[lbl setText:#"Powered By"];
[lbl setFont:[UIFont systemFontOfSize:10]];
[lbl setTextAlignment:NSTextAlignmentCenter];
[lbl setTextColor:[UIColor blackColor]];
District *school = [District new];
CGRect logoFrame = CGRectMake((view.bounds.size.width - 150) / 2.0, 25, 150, 37.5);
UIImageView * logoView = [[UIImageView alloc]initWithFrame:logoFrame];
logoView.image = [UIImage imageNamed:#"Logo.png"];
logoView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
[view addSubview:logoView];
[view addSubview:lbl];
return view;
}
This assumes the label should fill the width and the image should stay centered left-to-right.
I need to create a UIView with a UILabel subview programmatically because it works better than IB for animations. I cannot get the UIView to recognize the UILabel though. Here is my code from viewDidLoad:
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(764, 94, 200, 100)];
[label setText:#"Hello"];
[label setTextColor:[UIColor redColor]];
[label setBackgroundColor:[UIColor clearColor]];
UIView *hintView = [[UIView alloc]initWithFrame:CGRectMake(764, 94, 240, 198)];
[hintView setBackgroundColor:[UIColor colorWithRed:(34/255.f) green:(59/255.f) blue:(27/255.f) alpha:(255/255.f)]];
[hintView addSubview:label];
[self.view addSubview:hintView];
NSLog(#"subview %#", hintView.subviews);
Thanks
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(764, 94, 200, 100)];
You are setting wide frame try this
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 100)];
Change yourLable.frame.origin.x between (0) to (320 - withOfYourLabel)
Above code is same for your custom UIView (set X)
And if you want to get subViews of your custom view then follow
for(UIView *subView in hintViewsubviews)
{
/// here you got all subview of hintView
if([subView isKindOfClass:[UILabel class]])
{
// here you can also check that subView is UILabel or not ?
}
}
You are taking same frame size for both UIView and Label.bcz of that you are not getting proper output.See the changes which i have done to you code and try this
UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(hintView.frame.origin.x+15, hintView.frame.origin.y+50, hintView.frame.size.width-60, hintView.frame.size.height-100)];
[label setText:#"Hello"];
[label setTextColor:[UIColor redColor]];
[label setBackgroundColor:[UIColor clearColor]];
UIView *hintView = [[UIView alloc]initWithFrame:CGRectMake(764, 94, 240, 198)];
[hintView setBackgroundColor:[UIColor colorWithRed:(34/255.f) green:(59/255.f) blue:(27/255.f) alpha:(255/255.f)]];
[hintView addSubview:label];
[self.view addSubview:hintView];
NSLog(#"subview %#", hintView.subviews);
