Iphone 将UIView中的UIImageView对象添加到NSMutableArray

我相信我可能正在处理一些视图问题，这些问题不允许我检测并向数组中添加

UIImageView

对象。我真的需要一些建议

我有许多

uiimageview

，其中图像链接到

UIView

，该视图位于

UIViewController

之上（添加

UIView

有助于

drawRect

和一些其他优点）。所以，当我触摸一个图像并“拖放”它时，我想在拖放时将该图像添加到数组中

My

TouchesBegind

获取触摸的位置，并检查正在触摸的

UIImageView

，然后以该视图为中心，如下所示：

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

            UITouch *touch = [[event allTouches] anyObject];

            CGPoint location = [touch locationInView:self];  //can't use self.view in a UIView, this may be causing issues?

            startLocation = location;  // for reference as needed



    NSLog(@"Image x coord:   %f", location.x);

    NSLog(@"Image y coord:   %f", location.y);

    if ([touch view] == obiWan_Block)

            {obiWan_Block.center = location;}

    else if ([touch view] == r2d2_Block)

            {r2d2_Block.center = location;}

    else if ([touch view] == you_Block)

            {you_Block.center = location;}

}

NSLog(@"the quote array contains %d items. Contents = %@",[quoteArray count], quoteArray);

然后，我用

touchesMoved

拖动

UIImageView

，最后用

touchesend

拖动图像。当

UIImageView

被放置在屏幕的某个区域时，我会将其“捕捉”到特定位置。在这一点上，我想把这个

UIImageView

放到一个数组中，但我没有运气。我相信我对所涉及的各种视图以及通过

addObject

添加到我的

NSMutableArray

中的内容感到困惑。或者，我可能完全错过了什么。这是我的

toucheeded

方法：

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

          UITouch *touch = [[event allTouches] anyObject];

          CGPoint location = [touch locationInView:self];

          UIView *temp = [touch view];

          UIImageView *currentImageView = (UIImageView *)[touch view];  //DON'T THINK THIS IS RIGHT

    NSLog(@"Current Image View is:   %@", currentImageView);

    if ((location.x > dropZone.origin.x) && (location.y >= dropZone.origin.y) && ([touch view] != NULL))

        {

            CGRect frame = temp.frame;

            if (touchCount == 0) {

                frame.origin.x = 15;

                frame.origin.y = 180;

                temp.frame = frame;

                [quoteArray addObject: currentImageView];

                touchCount++;

                }

            else if (touchCount == 1) {

                frame.origin.x = 70;

                frame.origin.y = 180;

                temp.frame = frame;

                [quoteArray addObject: currentImageView]; 

                touchCount++;

                }

                ....

我有一个

NSLog

语句来检查

addObject

是否按如下方式工作：

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

            UITouch *touch = [[event allTouches] anyObject];

            CGPoint location = [touch locationInView:self];  //can't use self.view in a UIView, this may be causing issues?

            startLocation = location;  // for reference as needed



    NSLog(@"Image x coord:   %f", location.x);

    NSLog(@"Image y coord:   %f", location.y);

    if ([touch view] == obiWan_Block)

            {obiWan_Block.center = location;}

    else if ([touch view] == r2d2_Block)

            {r2d2_Block.center = location;}

    else if ([touch view] == you_Block)

            {you_Block.center = location;}

}

NSLog(@"the quote array contains %d items. Contents = %@",[quoteArray count], quoteArray);

日志上总是说：

quote数组包含0项。内容=（空）

请指教，谢谢

代码的最后一部分显示您未初始化

quotarray

。在创建代码时检查代码，我想您在init方法中遗漏了一些东西。因为如果阵列正确，则NSLog应显示如下：

NSArray *quoteArray = [NSArray array];
NSLog(@"%@", quoteArray);

谢谢我确实在错误的位置初始化了我的

NSMutableArray

。总是简单的事情需要花上几个小时才能解决！：-）
