I wrote a code with a UILabel with the name of a meteorological station. Later, I added the code to put a UITableView with a grid view like this website explains http://www.recursiveawesome.com/blog/2011/04/06/creating-a-grid-view-in-ios/
The problem is that now the Table view is shown in all screen and the label can't be seen.
How do I make to put the elements in this order?
UILabel
UITableView
Thanks!
1 With a nib:
ReplyDeleteIf you use a nib you can simply size / layout your label and table view so that they are positioned as desired. A UITableView can be made any size and take up any portion of the screen.
2 Without a nib
Create / alloc / initialize your label and table, and then add them to the view:
[self.view addSubview:myTableView];
[self.view addSubview:myLabel];
The magic step to this is that you need to set the frame of both your label and table view. Thats something that is really custom so I cant help you with that without more direction however it may look something like this:
// the number 10 is used for padding purposes
CGSize labelWidth = CGSizeMake(self.view.frame.size.width-20, 1000.0f);
CGSize textSize = [myLable.text sizeWithFont:myLable.font constrainedToSize:labelWidth lineBreakMode:UILineBreakModeWordWrap];
myLable.frame = CGRectMake(10, 10, labelWidth.width, textSize.height);
myTableView.frame = CGRectMake(0, myLable.frame.origin.y+10, self.view.frame.size.width, self.view.frame.size.height - (myLable.frame.origin.y+10));
Please note that calculating frames can be done MANY ways. Also you will probably have to recalculate the frames manually for rotations.
Hope this helps Good Luck!
Depending on the answer to my questions in the comments, there are several answers.
ReplyDeleteIf you want the label to always be on top whether or not the tableview is scrolled, make sure you are using an instance of UIViewController, then create your two views. Set the frame appropriately and then add the label view and the table view as subviews to the main view.
If you want the label to scroll away, that's even easier. Your UIViewController can remain a subclass of UITableViewController. UITableView has a property called tableHeaderView. myTableView.tableHeaderView = labelView;
You could to like Rachel said
ReplyDelete[self.view addSubview:myTableView];
[self.view addSubview:myLabel];
or after placing it
[self.view bringSubviewToFront:myTableView]
