viewcontroller.m

#import "viewcontroller.h"

@interface viewcontroller ()

@end

@implementation viewcontroller

- (void)viewdidload {
  [super viewdidload];
  // do any additional setup after loading the view, typically from a nib.

  uibutton *button=[uibutton buttonwithtype:uibuttontyperoundedrect];
  button.frame=cgrectmake(10, 100, 100, 200);
  button.backgroundcolor=[uicolor redcolor];
  [button settitle:@"按钮" forstate:uicontrolstatenormal];
  [self.view addsubview:button];

  //按钮的动画效果
  [self buttonanimation:button];


}

//按钮出现的时候有一个动画效果
- (void)buttonanimation:(uibutton *)sender
{
  cakeyframeanimation *animation = [cakeyframeanimation animationwithkeypath:@"transform"];

  catransform3d scale1 = catransform3dmakescale(0.5, 0.5, 1);
  catransform3d scale2 = catransform3dmakescale(1.2, 1.2, 1);
  catransform3d scale3 = catransform3dmakescale(0.9, 0.9, 1);
  catransform3d scale4 = catransform3dmakescale(1.0, 1.0, 1);

  nsarray *framevalues = [nsarray arraywithobjects:
              [nsvalue valuewithcatransform3d:scale1],
              [nsvalue valuewithcatransform3d:scale2],
              [nsvalue valuewithcatransform3d:scale3],
              [nsvalue valuewithcatransform3d:scale4],
              nil];

  [animation setvalues:framevalues];

  nsarray *frametimes = [nsarray arraywithobjects:
              [nsnumber numberwithfloat:0.0],
              [nsnumber numberwithfloat:0.5],
              [nsnumber numberwithfloat:0.9],
              [nsnumber numberwithfloat:1.0],
              nil];
  [animation setkeytimes:frametimes];

  animation.fillmode = kcafillmodeforwards;
  animation.duration = 0.3f;

  [sender.layer addanimation:animation forkey:@"dspopupanimation"];
}
