iOS animation Learning (-) UIView self-animating

In iOS development, some common simple animations can be animated with uivew to achieve

Learn about UIVIew some popular animations today

1.

Flipped animation    [UIView beginanimations:@ "Doflip" context:nil];    settings are often    [UIView setanimationduration:1];    Set animation fade    [UIView setanimationcurve:uiviewanimationcurveeaseinout];    Set Agent    [UIView setanimationdelegate:self];    Set rollover Direction    [UIView setanimationtransition:     uiviewanimationtransitionflipfromleft  Forview: Self.redview Cache:yes];    End of animation    [UIView commitanimations];

Effect:

2. Displacement animation

[UIView beginanimations:@ "move"  Context:nil];    [UIView setanimationduration: 2 ];    [UIView setanimationdelegate:self];     // Change the value    of x, y of its frame Self.redview.frame=cgrectmake (+);    [UIView commitanimations];

Effect:

Another way to do this:

[UIView animatewithduration:0.5 delay:0.1 usingspringwithdamping:0.5 initialspringvelocity:5.0 options: Uiviewanimationoptioncurveeaseinout animations:^{        Cgpoint point = _redview.center;        Point.y + =;        [_redview setcenter:point];    } completion:^ (BOOL finished) {            }];

Effect:

3. Keyframe Animation

 void (^keyframeblock) () = ^ () {//Create color array nsarray *arraycolors = @[[uicolor Orangecolor],                                 [Uicolor Yellowcolor], [Uicolor Greencolor], [Uicolor Bluecolor], [Uicolor Purplecolor], [Uicolor REDC        Olor]];        Nsuinteger Colorcount = [arraycolors count];  Loop add Keyframe for (Nsuinteger i = 0; i < Colorcount; i++) {[UIView addkeyframewithrelativestarttime:i/                                          (cgfloat) Colorcount relativeduration:1/(cgfloat) Colorcount                                          animations:^{[_redview Setbackgroundcolor:arraycolors[i]];        }];    }    }; [UIView animatekeyframeswithduration:5.0 delay:0.0 Optio Ns:uiviewkeyframeAnimationoptioncalculationmodecubic | Uiviewanimationoptioncurvelinear Animations:keyframeblock Comple                              tion:^ (BOOL finished) {//After the animation is completed//code ... }];
