iOS Animation 001

Animation is Easy, today We learning basic Animation use  UIImageView(just like play film).

First need prepare a set of image frames, you can use PhotoShop or any other image edit tool do this.

Second Open Xcode , setup a project from "Single view Application" template.

Three some type 

     

@interface KKViewController ()

@property (strong, nonatomic) IBOutlet UIImageView *gear;

@property (strong, nonatomic) IBOutlet UIButton *actionBtn;

@end

- (void)viewDidLoad

{

    [super viewDidLoad];

    NSMutableArray *images=[NSMutableArray arrayWithCapacity:36];

    for (int i=0; i< 36; i++) {

        [images addObject:[UIImage imageNamed:[NSString stringWithFormat: @"GearAnimation%d",i]]];

    }

    _gear.animationImages = images;

    _gear.animationDuration = [_gear.animationImages count] / 30;

    

// Do any additional setup after loading the view, typically from a nib.

}

- (IBAction)startStopAction:(id)sender {

    if ([_gear isAnimating]) {

        [_gear stopAnimating];

        [_actionBtn setTitle:@"Stop" forState:UIControlStateNormal];

    }else{

        [_gear startAnimating];

        [_actionBtn setTitle:@"Start" forState:UIControlStateNormal];

    }

}

don't forget  to make connect in nib file or storyboard. 

Let's go , woo!

It's too simple ?  

I upload project code to github, you can download from here
