如何将标签设置为UIImageview图像等于iOS中每个图像的数组索引？

我是iOS开发的新手。我想设置标记imageview图像等于其在数组索引中的值，就像我的数组包含50个图像链接一样，我将imageview设置为图像代码，就像

for(int index=0; index < [self.imagesa count]; index++)
{
    NSDictionary *dict=[self.imagesa objectAtIndex:index];
    NSString *image=[dict valueForKey:@"link"];
    smallImage = [[UIImageView alloc] init];
    pageLabel=[[UILabel alloc]init];
    smallImage.tag=index;
    smallImage.bounds = CGRectMake(10, 10, self.scrollView.frame.size.width, self.scrollView.frame.size.width);
    smallImage.frame = CGRectMake(5+xOffset, 0, 50, 50);
    [smallImage sd_setImageWithURL:[NSURL URLWithString:image] placeholderImage:[UIImage imageNamed:@"1.png"]];
    [self.imageArray insertObject:smallImage atIndex:index];
    CGSize scrollViewSize=CGSizeMake(self.scrollView.frame.size.width*[self.imageArray count], self.scrollView.frame.size.height);
    [self.scrollView setContentSize:scrollViewSize];
    CALayer *borderLayer = [CALayer layer];
    CGRect borderFrame = CGRectMake(10, 10, (smallImage.frame.size.width), (smallImage.frame.size.height));
    [borderLayer setBackgroundColor:[[UIColor clearColor] CGColor]];
    [borderLayer setFrame:borderFrame];
    [borderLayer setCornerRadius:kCornerRadius];
    [borderLayer setBorderWidth:kBoarderWidth];
    [borderLayer setBorderColor:[[UIColor redColor] CGColor]];
    [smallImage.layer addSublayer:borderLayer];
    [self.scrollView addSubview:smallImage];
    [self.scrollView addSubview:pageLabel];
    [self.scrollView addSubview:[self.imageArray objectAtIndex:index]];
    xOffset += 60;
}

for（int index=0；index<[self.imagesa count]；index++）
{
NSDictionary*dict=[self.imagesa objectAtIndex:index]；
NSString*image=[dict valueForKey:@“link”]；
smallImage=[[UIImageView alloc]init]；
pageLabel=[[UILabel alloc]init]；
tag=index；
smallImage.bounds=CGRectMake（10,10，self.scrollView.frame.size.width，self.scrollView.frame.size.width）；
smallImage.frame=CGRectMake（5+xOffset，0,50,50）；
[smallImage sd_setImageWithURL:[NSURL URLWithString:image]占位符图像：[UIImage ImageName:@“1.png”]；
[self.imageArray insertObject:smallImage-atIndex:index]；
CGSize scrollViewSize=CGSizeMake（self.scrollView.frame.size.width*[self.imageArray count]，self.scrollView.frame.size.height）；
[self.scrollView setContentSize:scrollViewSize]；
CALayer*边界层=[CALayer层]；
CGRect borderFrame=CGRectMake（10,10，（smallImage.frame.size.width），（smallImage.frame.size.height））；
[borderLayer setBackgroundColor:[[UIColor clearColor]CGColor]]；
[边界层设置框架：边界框架]；
[边界层设置角半径：kCornerRadius]；
[borderLayer SetBoardWidth:kBoarderWidth]；
[borderLayer setBorderColor:[[UIColor redColor]CGColor]]；
[smallImage.layer addSublayer:borderLayer]；
[self.scrollView addSubview:smallImage]；
[self.scrollView addSubview:pageLabel]；
[self.scrollView addSubview:[self.imageArray objectAtIndex:index]]；
xOffset+=60；
}

在这里，我想好像我选择了第五个图像，那么它的标签也是五个，怎么可能呢？在这里，我设置了imageview.tag=index，但它总是作为我的数组计数值返回。请给我每个imagetag等于其数组索引的解决方案

thnx。您需要在scrollview中添加按钮并设置标签

for(int index=0; index < [self.imagesa count]; index++)
{
    NSDictionary *dict=[self.imagesa objectAtIndex:index];
    NSString *image=[dict valueForKey:@"link"];
    smallImage = [[UIImageView alloc] init];
    imageButton =[UIButton buttonWithType:UIButtonTypeCustom];

    pageLabel=[[UILabel alloc]init];
    smallImage.tag=index;
    smallImage.bounds = CGRectMake(10, 10, self.scrollView.frame.size.width, self.scrollView.frame.size.width);
    smallImage.frame = CGRectMake(5+xOffset, 0, 50, 50);
    imageButton.frame=CGRectMake(5+xOffset, 0, 50, 50);
    imageButton.tag=index;
    [imageButton addTarget:self action:@selector(imageClicked:) forControlEvents:UIControlEventTouchUpInside];
    [smallImage sd_setImageWithURL:[NSURL URLWithString:image] placeholderImage:[UIImage imageNamed:@"1.png"]];
    [self.imageArray insertObject:smallImage atIndex:index];
    CGSize scrollViewSize=CGSizeMake(self.scrollView.frame.size.width*[self.imageArray count], self.scrollView.frame.size.height);
    [self.scrollView setContentSize:scrollViewSize];
    CALayer *borderLayer = [CALayer layer];
    CGRect borderFrame = CGRectMake(10, 10, (smallImage.frame.size.width), (smallImage.frame.size.height));
    [borderLayer setBackgroundColor:[[UIColor clearColor] CGColor]];
    [borderLayer setFrame:borderFrame];
    [borderLayer setCornerRadius:kCornerRadius];
    [borderLayer setBorderWidth:kBoarderWidth];
    [borderLayer setBorderColor:[[UIColor redColor] CGColor]];
    [smallImage.layer addSublayer:borderLayer];
    [self.scrollView addSubview:smallImage];
    [self.scrollView addSubview:imageButton];
    [self.scrollView addSubview:pageLabel];
    [self.scrollView addSubview:[self.imageArray objectAtIndex:index]];
    xOffset += 60;
}

for（int index=0；index<[self.imagesa count]；index++）
{
NSDictionary*dict=[self.imagesa objectAtIndex:index]；
NSString*image=[dict valueForKey:@“link”]；
smallImage=[[UIImageView alloc]init]；
imageButton=[UIButton按钮类型：UIButtonTypeCustom]；
pageLabel=[[UILabel alloc]init]；
tag=index；
smallImage.bounds=CGRectMake（10,10，self.scrollView.frame.size.width，self.scrollView.frame.size.width）；
smallImage.frame=CGRectMake（5+xOffset，0,50,50）；
frame=CGRectMake（5+xOffset，0,50,50）；

[imageButton addTarget:自我操作：@选择器（imageClicked:）forControlEvents:UIControlEventTouchUpInside]；
[smallImage sd_setImageWithURL:[NSURL URLWithString:image]占位符图像：[UIImage ImageName:@“1.png”]；
[self.imageArray insertObject:smallImage-atIndex:index]；
CGSize scrollViewSize=CGSizeMake（self.scrollView.frame.size.width*[self.imageArray count]，self.scrollView.frame.size.height）；

[smallImage.layer addSublayer:borderLayer]；
[self.scrollView addSubview:smallImage]；
[self.scrollView addSubview:imageButton]；
[self.scrollView addSubview:pageLabel]；
[self.scrollView addSubview:[self.imageArray objectAtIndex:index]]；
xOffset+=60；
}

//（或）

for（int index=0；index<[self.imagesa count]；index++）
{
NSDictionary*dict=[self.imagesa objectAtIndex:index]；

smallImage=[[UIImageView alloc]init]；

}
-（无效）handleSingleTap:（UITapGestureRecognitor*）识别器
{
UIImageView*当前图像=（UIImageView*）[识别器视图]；
NSLog（@“%d”，currentimage.tag）；
}

您可以在imageClicked按钮操作处获取标记
