尝试将动画部分放在控制器类中而不是在子类按钮类中.

//in customButton.h file

#import

@interface customButton : UIButton

- (id)initWithFrameOfCustomButton:(CGRect)frame;

- (void)animate;//this method u need to add and call it from the controller

@end

//in the subclassed UIButtin class

//in customButton.m file

#import "customButton.h"

#import

@implementation customButton

- (id)initWithFrame:(CGRect)frame

{

self = [super initWithFrame:frame];

if (self) {

// Initialization code

}

return self;

}

- (id)initWithFrameOfCustomButton:(CGRect)frame

{

self = [super initWithFrame:frame];

if(self)

{

//hear only set the frame only not incude animation part

//this is the custom initiliser that initilises the custom button with the given frame and also make it to round

self.frame = frame;

self.backgroundColor = [UIColor greenColor];

self.layer.cornerRadius = frame.size.width/2;

self.layer.masksToBounds = YES;

}

return self;

}

//add the animation part

- (void)animate //this method is called within the this class

{

[UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{

self.layer.affineTransform = CGAffineTransformMakeScale(0.0f,0.0f);

//edit: comment below lines becz u already made it to round

// self.layer.cornerRadius = 0.0f;

// self.layer.masksToBounds = YES;

// self.clipsToBounds = YES;

// CATransform3D t = CATransform3DIdentity;

// t = CATransform3DMakeScale(0,1.0f);

// cButton.layer.transform = t;

} completion:^(BOOL finished) {

[UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{

self.layer.affineTransform = CGAffineTransformMakeScale(1.0f,1.0f);

// edit comment below lines

// self.layer.cornerRadius = self.frame.size.width/2;

// self.layer.masksToBounds = YES;

// self.clipsToBounds = YES;

// CATransform3D t = CATransform3DIdentity;

// t = CATransform3DMakeScale(1,1,1.0f);

// cButton.layer.transform = t;

} completion:nil];

}];

}

//implement touch handling methods to call animation

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{

[self animate];

}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event

{

[self animate];

}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

{

// [self animate];

}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event

{

// [self animate];

}

在控制器类中包括如下的动画部分

//in the view controller that u are using this custom button

#import "FirstViewController.h"

#import "CustomCell.h"

#import "customButton.h"

#import

@interface FirstViewController ()

@end

@implementation FirstViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

}

return self;

}

- (void)viewDidLoad

{

[super viewDidLoad];

// Do any additional setup after loading the view from its nib.

customButton *cButton = [[customButton alloc]initWithFrameOfCustomButton:CGRectMake(20,30,100,100)]; //hear i am initilising the custom button

cButton.tag = 100;//assigning tag to access during the animation

[self.view addSubview:cButton];

// [self makeAnimation];//i am animation rite after it loads the all views u can place this method call where ever u want

//edit: i am commenting the this line so animations of the button in this class won't call

}

//edit below method is added

- (void)viewDidAppear:(BOOL)animated

{

customButton *cButton = (customButton *)[self.view viewWithTag:100];

//edit->comment this line so that u never call the animation from view controller

// [cButton animate];//animating the button the code in the subclassed method is called

}

- (void)makeAnimation

{

customButton *cButton = (customButton *)[self.view viewWithTag:100];//get the custom button by using the tag

[UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{

cButton.layer.affineTransform = CGAffineTransformMakeScale(0.0f,0.0f);

// cButton.layer.cornerRadius = 0.0f;

// cButton.layer.masksToBounds = YES;

// cButton.clipsToBounds = YES;

// CATransform3D t = CATransform3DIdentity;

// t = CATransform3DMakeScale(0,1.0f);

// cButton.layer.transform = t;

} completion:^(BOOL finished) {

[UIView animateWithDuration:0.1 delay:0.0 options:UIViewAnimationOptionCurveEaseInOut animations:^{

cButton.layer.affineTransform = CGAffineTransformMakeScale(1.0f,1.0f);

// cButton.layer.cornerRadius = cButton.frame.size.width/2;

// cButton.layer.masksToBounds = YES;

// cButton.clipsToBounds = YES;

// CATransform3D t = CATransform3DIdentity;

// t = CATransform3DMakeScale(1,1.0f);

// cButton.layer.transform = t;

} completion:nil];

}];

}

注意UIButton继承自：UIControl – > UIView – > UIResponder – > NSObject的

如果你感到困惑,请查看文档

如果你想使用UIControlers,即响应者,那么你需要实现这些方法

你可以得到你想要的活动,

在您的子类UIButton类中,通过注释触摸处理方法来实现它

- (BOOL)beginTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event

{

return YES;

}

- (void)endTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event

{

}

- (BOOL)continueTrackingWithTouch:(UITouch *)touch withEvent:(UIEvent *)event

{

return YES;

}
