Cakeyframeanimation-ibaby of IOS Core animations

-Cakeyframeanimation of IOS core animations

-Brief introduction

is a subclass of Capropertyanimation, the difference with cabasicanimation is that cabasicanimation can only change from one numeric value (Fromvalue) to another (Tovalue), And Cakeyframeanimation will use a nsarray to save these values

-Attribute parsing:

-Values: This is the Nsarray object above. The elements inside are called "keyframes" (keyframe). The animated object displays each keyframe in the values array in the specified time (duration), in turn

-Path: You can set a cgpathref\cgmutablepathref so that the layer moves along the path. Path only works on Calayer's anchorpoint and position. If you set the path, the values will be ignored

-Keytimes: You can specify a corresponding point in time for the corresponding keyframe, with a value range of 0 to 1.0,keytimes each time value corresponds to each frame in values. When the keytimes is not set, the time of each keyframe is equally divided.

-Description: Cabasicanimation can be seen as a maximum of only 2 keyframes cakeyframeanimation

-Mode of values:

-Cakeyframeanimation *animation = [cakeyframeanimation animation];

Animation.keypath = @ "position";

Nsvalue *value1=[nsvalue valuewithcgpoint:cgpointmake (100, 100)];

Nsvalue *value2=[nsvalue Valuewithcgpoint:cgpointmake (200, 100)];

Nsvalue *value3=[nsvalue Valuewithcgpoint:cgpointmake (200, 200)];

Nsvalue *value4=[nsvalue valuewithcgpoint:cgpointmake (100, 200)];

Nsvalue *value5=[nsvalue valuewithcgpoint:cgpointmake (100, 100)];

[Email protected] [Value1,value2,value3,value4,value5]; Animation.repeatcount=maxfloat;

Animation.removedoncompletion = NO;

Animation.fillmode = Kcafillmodeforwards;

Animation.duration = 4.0f;

Animation.timingfunction=[camediatimingfunction Functionwithname:kcamediatimingfunctioneaseineaseout];

animation.delegate=self;

[Self.myView.layer addanimation:animation Forkey:nil];

-Path Mode:

-Cakeyframeanimation *animation = [cakeyframeanimation animation];

Animation.keypath = @ "position";

Cgmutablepathref path=cgpathcreatemutable ();

Cgpathaddellipseinrect (Path, NULL, CGRectMake (150, 100, 100, 100));

Animation.path=path;

Cgpathrelease (path);

Animation.repeatcount=maxfloat;

Animation.removedoncompletion = NO;

Animation.fillmode = Kcafillmodeforwards;

Animation.duration = 4.0f;

Animation.timingfunction=[camediatimingfunction Functionwithname:kcamediatimingfunctioneaseineaseout];

animation.delegate=self;

[Self.myView.layer addanimation:animation Forkey:nil];
