Is there a way where i could add a UILabel on top of a UIImageView programmatically ?
So finally there should be a label displayed on top of a Image.
UIImageView is a subclass of UIView so you can add any UI object onto it.
UILabel *xlabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 20)];
xlabel.text = #"xxx";
[myImageView addSubview:xLabel];
As simple as
[imageView addSubview:yourLabel];

I have an imageView. I need to restrict the size of imageView to the white background imageOnly.The image is tightly bounded between right,left and top margin. I am confused on how to do at bottom, such that the image must fit in the white background only. How do I do that ?

The code I am using
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(25, 240,175,205)];
Frame width and height is 205*205
You can add your imageView as a subview of the view with the white background.
UIView *whiteBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(25,240,205,205)];
CGSize whiteSize = whiteBackgroundView.frame.size;
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0,size.width,size.height)];
[whiteBackgroundView addSubview:_imageView];
In the example your imageView will completely fit the size of the white background view.
Try this
UIView *productView = [[UIView alloc]initWithFrame:CGRectMake(25, 240,225,225)];
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10,205,205)];
_imageView.clipsToBounds =YES;
[productView addSubview:_imageView];
[self.view addSubview:ImageBackview];
just create one view and add this image in it, for example use bellow code..
UIView *ImageBackview = [[UIView alloc]initWithFrame:CGRectMake(25, 240,225,225)];
_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10,205,205)];
[ImageBackview addSubview:_imageView];
[self.view addSubview:ImageBackview];
I wan to design a settings page, in which I have to draw lines between multiple labels, what is the best way to do this, I have googled around, got to know about CGContextRef approach. Is this the proper way, I need to have a line between labels (consecutively). Can I go ahead with this approach or any other best way is there.
I have given base view as dark color and I am adding labels as white, I am giving a line gap between two labels its looking like a line. No extra work :)
May be just add UIView between labels? Something Like this:
UILabel *topLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];
//Label settings
[self addSubview:topLabel];
[topLabel release];
UIView *separator = [[UIView alloc] initWithFrame:CGRectMake(topLabel.frame.origin.x, CGRectGetMaxY(topLabel.frame), topLabel.frame.size.width, 2)];
separator.backgroundColor = [UIColor blackColor];
UILabel *bottomLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, CGRectGetMaxY(separator.frame), 320, 20)];
//Label settings
[self addSubview:bottomLabel];
[bottomLabel release];
Couldn't you just create a custom UIView class with a UILabel and a UIView as the subviews of this custom view class?
class CustomView : UIView
{
UIView *line;
UILabel *label;
}
#property(nonatomic, retain) UIView *line;
#property(nonatomic, retain) UILabel *label;
For the UIView subview, you can tell it to use the width of the parent UIView.
I need to have a footer in my view that says "Powered by: {image_logo_of_my_company}" How do I achieve that?
Make a wrapper view of type UIView and add a UILabel and the logo in a UIImageView inside that view at the appropriate coordinates.
UIView *wrapper = [[UIView alloc] initWithFrame:footerFrame];
UILabel *label = [[UILabel alloc] initWithFrame:
CGRectMake(0, 0, footerFrame.size.width*0.6, footerFrame.size.height)];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:
CGRectMake(footerFrame.size.width*0.6, 0,
footerFrame.size.width*(1.0-0.6), footerFrame.size.height)];
[wrapper addSubView:label];
[wrapper addSubView:imageView];
label.text = #"Powered by: ";
imageView.image = [UIImage imageNamed:#"logo"]; // assumes logo.png & logo#2x.png
[viewNeedingFooter addSubView:wrapper];
Assuming you need 60% of the width of the footer for the label and 40% for the logo.
After adding a background (image) to my UIView (View_0) I wish to implement a button to remove the same background.
How can I do it? I have tried to set a different image as the background of View_0 but this does not work (I suspect this background is set behind "image").
I don't want to use
[View_0 removeFromSuperview];
as I need View_0 to still be there for other purposes....
//Create an ImageView
UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 940, 422)];;
//Add the ImageView as the background of the View_0
[View_0 addSubview:image];
//Move custom image behind View
[View_0 sendSubviewToBack: image];
//Failed attempt to remove the background....
View_0.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"defaultImage.PNG"]];
You have added a UIImageView to the View and Not the background of the view. So what is happening is that when u implement
View_0.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"defaultImage.PNG"]];
The background of the View is being set but the UIImageView is now on top of the View so that is why the background of the View is not being shown.
Instead if you simply want to add the background you can change it to the Action of the UIButton.
Also if you use [View_0 removeFromSuperview]; you are trying to remove the view which is not right.
//Create an ImageView
UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 940, 422)];;
image.tag = 1234;
//Add the ImageView as the background of the View_0
[View_0 addSubview:image];
//Move custom image behind View
[View_0 sendSubviewToBack: image];
UIImageView *imgView = [self.view viewWithTag:1234];
[img setImage:nil];
This should work i think
I'm new to programming, and I know how to add a static image behind a tableView in a .xib file, but not in code. I have tried the following code:
UIImage * image = [UIImage imageNamed:#"pic.png"];
[self.view addSubView: image];
but nothing happens when I write this!
To display an UIImage you have to use an UIImageView and put it under the UITableView using the same frame. Don't forget to set the table view's background to transparent.
UIImageView *iv = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"pic.png"]];
iv.frame = CGRectMake(0.0, 0.0, 300.0, 600.0);
UITableView *tv = [[UITableView alloc] initWithFrame:iv.frame style:UITableViewStylePlain];
tv.opaque = NO;
tv.backgroundColor = [UIColor clearColor];
[self.view addSubView: iv];
[self.view addSubView: tv];
[iv release];
[tv release];
You need to use a UIImageView, not a UIImage. Also, when adding a view programmatically, don't forget to set the frame.
