Question

I want to put a text label during the start up of a program, some sort of a text instruction for 5 second only and disappear. May I know how to do so in iOS ? Here is my code example.

NSString *displayText = [[NSString alloc] initWithFormat: @"Please select your item.",

startup.text = displayText ;

Answer 1

After the following statement,

startup.text = displayText ;

start a NSTimer that will fire after certain duration.

[NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(hideLabel:) userInfo:nil repeats:NO];

In hideLabel: method, you hide that.
