ios 类似淘宝评论星星功能

创建星星视图:

//星星

_myview = [[UIView alloc]initWithFrame:CGRectMake(95, 5, 200, 50)];

UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(huadong:)];

[_myview addGestureRecognizer:pan];

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(dianji:)];

[_myview addGestureRecognizer:tap];

[view1 addSubview:_myview];

for (int i = 0; i < 5; i++) {

imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"star01"]];

imageView.frame = CGRectMake(_myview.bounds.origin.x+((i+1)*24), _myview.bounds.origin.y, 24, 24);

[_myview addSubview:imageView];

[_allStar addObject:imageView];

}

//分别在点击和滑动手势实现方法

#pragma mark - 滑动的坐标

-(void)huadong:(UIPanGestureRecognizer *)pan{

CGPoint translation = [pan locationInView:_myview];

for(int i = 0;i < 5 ; i++)

{

UIImageView *im ;

im = _allStar[i];

//NSLog(@"_all[%i] = (%f,%f)",i,im.frame.origin.x,im.frame.origin.y);

if ((translation.x > 0)&&(translation.x < 144)&&(translation.y > 0)&&(translation.y < 24))

{

NSString *myscore = [NSString stringWithFormat:@"%i",((int)translation.x)/24];

//UILabel *score = [[UILabel alloc]initWithFrame:CGRectMake(150, 180, 100, 100)];

//[scrollView addSubview:score];

//score.text = myscore;//_score是一个UILable，myscore为分数，显示在给用户看，关于这个不在赘述

star = [myscore intValue];

//星星

if (im.frame.origin.x > translation.x)

{

im.image =[UIImage imageNamed:@"star01"];

}

else

{

im.image =[UIImage imageNamed:@"star02"];

}

}

}

}

#pragma mark - 点击的坐标

-(void)dianji:(UITapGestureRecognizer *)tap{

CGPoint translation = [tap locationInView:_myview];

for(int i = 0;i < 5 ; i++){

UIImageView *im ;

im = _allStar[i];

if ((translation.x > 0)&&(translation.x < 144)&&(translation.y > 0)&&(translation.y < 24)) {

NSString *myscore = [NSString stringWithFormat:@"%i",((int)translation.x)/24];

//星星

star = [myscore intValue];

if (im.frame.origin.x > translation.x) {

im.image =[UIImage imageNamed:@"star01"];

}else{

im.image =[UIImage imageNamed:@"star02"];

}

}

}

}
