Ios ui label customizing tutorial

Customizing a ios ui label

Here in this tutorial we will look how to customize a label. By having the knowledge of label customization you can easily customize your button on any view that we have for iPhone development.

So let us see how to customize a label:

1. Setting background
You can set a background color to your label by using "backgroundcolor" attribute of a label. For example:

Code:
Select All

UILabel *backGround = [[UILabel alloc] initWithFrame:CGRectMake(100, 50, 130, 20)];
backGround.backgroundColor = [UIColor redColor];
backGround.text = @"Red Background";

2. Setting text color
You can set color for text by using "textcolor" attribute of label. For example:

Code:
Select All

UILabel *redText = [[UILabel alloc] initWithFrame:CGRectMake(130, 80, 90, 20)];
redText.text = @"Red Color";
redText.textColor = [UIColor redColor];

3. Setting a border to your label
You can set border to your label by using "borderwidth" attribute. but for using this attribute u need to import "quartzcore/quartzcore. H ". importing this you can access layer attribute of a label. see the example below:

Code:
Select All

UILabel *borderLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 110, 130, 20)];
borderLabel.text = @"Text with border";
borderLabel.layer.borderColor = [UIColor darkGrayColor].CGColor;
borderLabel.layer.borderWidth = 2.0;

4. Setting text to the center of your label
You can set text to the center of your label by using "textalignment" attribute. For example:

Code:
Select All

UILabel *centerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 140, 300, 20)];
centerLabel.text = @"Text at the center of the label";
centerLabel.textAlignment = UITextAlignmentCenter;
centerLabel.layer.borderColor = [UIColor blackColor].CGColor;
centerLabel.layer.borderWidth = 1.0;

5. Multiple Line Text
You can set multiple lines for your text within a special label. for achieving this you have to specify the number of lines you want in your label. you can do that using "numberoflines" attribute. see example given below:

Code:
Select All

UILabel *multipleLines = [[UILabel alloc] initWithFrame:CGRectMake(120, 170, 90, 40)];
multipleLines.text = @"Multiple Lines";
multipleLines.numberOfLines = 2;
multipleLines.textAlignment = UITextAlignmentCenter;
multipleLines.layer.borderColor = [UIColor blackColor].CGColor;
multipleLines.layer.borderWidth = 1.0;

6. Setting text to bold
You can set your text to bold by using "font" attribute. Example:

Code:
Select All

UILabel *boldText = [[UILabel alloc] initWithFrame:CGRectMake(130, 220, 90, 20)];
boldText.font = [UIFont boldSystemFontOfSize:15];
boldText.text = @"Bold Text";

7. Setting font to a text
Font to a text can be set using "setfont" function. See the example given below

Code:
Select All

UILabel *fontText = [[UILabel alloc] initWithFrame:CGRectMake(70, 250, 200, 20)];
[fontText setFont:[UIFont fontWithName:@"American Typewriter" size:18]];
fontText.text=@"American Typewriter";

8. Applying rounded corners to your label
Rounded corners can be applied to your label by using "cornerradius" attribute. you just have to mention the radius for the corner you want to have. see the example given below; it will clear your idea.

Code:
Select All

UILabel *roundedCorners = [[UILabel alloc] initWithFrame:CGRectMake(70, 280, 200, 20)];
roundedCorners.layer.cornerRadius = 6.0;
roundedCorners.layer.borderWidth = 1.0;
roundedCorners.textAlignment = UITextAlignmentCenter;
roundedCorners.text = @"Rounded Corners";

Thus we can apply styles to our label. Too more things can be done but these are the basic things. Please e more and enjoy.
