How to add a delay of Timer between the execution of two lines of code in XCODE...

In this tutorial I am going to demenstrate how to add a Timer or delay between the execution of two lines of code. For example lets say you have one button and one UILABEL in a your xcode project. When the user clicks on the button it is to do the following:

1.)  send the variable dice to the UILABEL
2.) Two seconds later it will clear the text on the label.

This is how I have gotten this accomplished.

I have an IBACTION called randomNumber that I have linked to the button in my project.

-(IBAction)randomNumber {

int dice = 1 + arc4random() % (20);

label.text = [NSString stringWithFormat:@"%d", dice];

// perform selector after delay

[self performSelector:@selector(ClearLabel) withObject:nil afterDelay:2];

}

- (void)ClearLabel 

{

label.text = @"";

}

How to call a method AKA IBACTION in an XCODE project.

To call a Method or IBACTION in an XCODE project you have to use the following command.




[self methodname];




for example lets say you have the following methods AKA IBACTIONS in your .h file of you xcode project.




-(IBAction)method1;
-(IBAction)method2;

-(IBAction)method3;

-(IBAction)method4;





And you have all of them defined as following in your .M File of your XCODE project.


-(IBAction)method1

{

//do something

}







-(IBAction)method2


{


//do something


}









-(IBAction)method3


{


//do something


}









-(IBAction)method4


{


//do something


}
















Now for example if you want to call method2 from method1 you will do the following:







-(IBAction)method1


{


[self method2];






}






This is a fundamental concept in XCODE to understand.
