Objective-C

    NSString *title = [segment titleForSegmentAtIndex:segment.selectedSegmentIndex];

Swift:

    let title = segment.titleForSegment(at: segment.selectedSegmentIndex)



    [segmentedControl titleForSegmentAtIndex:int];

For the current selected index

    [segmentedControl titleForSegmentAtIndex:[segmentedControl selectedSegmentIndex]];

Swift 3:

    segmentedControl.titleForSegment(at: segmentedControl.selectedSegmentIndex)


As this is the first Google result and we are now in the swift era:

Swift:

    seg_ctrl.titleForSegmentAtIndex( seg_ctrl.selectedSegmentIndex)

Disable building workspace process in Eclipse

I need to develop a single routine that will be fired each 5 minutes to check if a list of SQL Servers (10 to 12) are up and running. 

Is there a way to simply &quot;ping&quot; a SQL Server from C# one with minimal code and sql operational requirements? 

What&#39;s the best way to test SQL Server connection programmatically?

How can I get the text value of a segment in a UISegmentedControl?

I already tried getting the current URL of my `UIWebView` with: `webview.request.URL`.
Unfortunately the `NSURL` was empty. Anything wrong here? I am working with Xcode 3.2.2 beta 5.

The code above should be executed in the `UIWebView` delegate `didStartLoad`.

I am giving a text view to tweet some string .

I am applying the following method to restrict the number of characters to 140 in length.

    - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{
       return [[textView text] length] &lt;= 140;
    }


The code is working nicely except the first condition that backspace is not working.
 suppose that  I have reached the limit of 140 characters so that the method will give me false and the user can not insert more characters but after that when I try to delete some characters the text view behave as it is disabled .

So the question is: &quot;How to delete characters from `textview.text` or re-enable the text view?&quot;

I have a `UIView` which has about 8 different `CALayer` sublayers added to its layer.
If **I modify the view&#39;s bounds** (animated), then the view itself shrinks (I checked it with a `backgroundColor`), but **the sublayers&#39; size remains unchanged**.

How to solve this?

CALayers didn&#39;t get resized on its UIView&#39;s bounds change. Why?

I need to determine whether a selected UIColor (picked by the user) is dark or bright, so I can change the color of a line of text that sits on top of that color, for better readability.

Here&#39;s an example in Flash/Actionscript (with demo):
http://web.archive.org/web/20100102024448/http://theflashblog.com/?p=173

Any thoughts?

Cheers,
Andre

**UPDATE**

Thanks to everyone&#39;s suggestions, here&#39;s the working code:

    - (void) updateColor:(UIColor *) newColor
    {
    	const CGFloat *componentColors = CGColorGetComponents(newColor.CGColor);
    	
    	CGFloat colorBrightness = ((componentColors[0] * 299) + (componentColors[1] * 587) + (componentColors[2] * 114)) / 1000;
    	if (colorBrightness &lt; 0.5)
    	{
    		NSLog(@&quot;my color is dark&quot;);
    	}
    	else
    	{
    		NSLog(@&quot;my color is light&quot;);
    	}
    }

Thanks once again :)

Check if UIColor is dark or bright?

I have added a `UISegmentedControl` in my application.  None of the buttons are selected in normal state.  I want to implement a button click event when the first segment is selected, and another event when another button is clicked.

How do I switch `UISegmentedControl` programmatically?

How do I switch UISegmentedControl programmatically?

Following is the code for `UISegmentedControl`

    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects: [UIImage imageNamed:@&quot;down.png&quot;], [UIImage imageNamed:@&quot;dList.png&quot;], nil]];  
    
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];  
    segmentedControl.frame = CGRectMake(0, 0, 90, 65);  
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;  
    segmentedControl.momentary = YES;  
    	
    UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];  
    	
    [segmentedControl release];  
    	
    self.navigationItem.rightBarButtonItem = segmentBarItem;  
    	
    [segmentBarItem release];    
    
and   
    
    - (void)segmentAction:(id)sender{
    	if([sender selectedSegmentIndex] == 0)
    	{
    		button.hidden=NO;
    	}
    	else
    	{
    		[self dListMethod ];
    	}
    }

In the if() section I want to disable `selectedSegmentIndex==0` and enable when `button.hidden=YES`
