Tuto 2 iPhone : How to Change Label Text Font&Color for iPhone

                              

     

In the previous tutorial, we saw how to make an action for a button to write text in a label.
In this tutorial, we will strengthen this aqcuis. Indeed, the previous code will add the necessary code to change the font and Colour of the text of a label.
So, let's starting .

                                            Download Source Code

                                              
1)Add in .h file this Code : 
UIButton *btnColor;
//.....
@property (nonatomic,retain)IBOutlet UIButton *btnColor;
//.....
- (IBAction)buttonPressedB:(id)sender;

So the full Code of this file become :

#import <UIKit/UIKit.h>


@interface demo2AddButtonViewController : UIViewController {


UILabel *mylabel;
UIButton *myButton;
UIButton *btnColor;


}
@property (nonatomic,retain)IBOutlet UILabel *myLabel;
@property (nonatomic,retain)IBOutlet UIButton *myButton;
@property (nonatomic,retain)IBOutlet UIButton *btnColor;
- (IBAction)buttonPressed:(id)sender;
- (IBAction)buttonPressedB:(id)sender;
@end

=>Indeed, the addition of this code is used to define another button and also to define its action

2)Add this Code in the .m file : 

@synthesize btnColor;

//.....

- (IBAction)buttonPressedB:(id)sender

{

[myLabel setTextColor:[UIColor redColor]];

[myLabel setFont:[UIFont boldSystemFontOfSize:33]];

}

The Full Code OF .m file : 

#import "demo2AddButtonViewController.h"


@implementation demo2AddButtonViewController
@synthesize myLabel;
@synthesize myButton;
@synthesize btnColor;


- (IBAction)buttonPressed:(id)sender
{
[myLabel setText:@"Peace Up To You"];
}
- (IBAction)buttonPressedB:(id)sender
{
[myLabel setTextColor:[UIColor redColor]];
[myLabel setFont:[UIFont boldSystemFontOfSize:33]];
}

- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

// Release any cached data, images, etc that aren't in use.
}


- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}




- (void)dealloc {
    [super dealloc];
}


@end

Don't forget  to link your Action  To its method( buttonPressedB).

As yo see, It's the same principle as the first tuto,But  this tutorial lets you practice using , advancing well.
