【问题描述】：

我正在尝试为 iCarousel 项目视图实现缩放功能。这是我的代码：

NSString *pathToHDImage = [documentsFolderPath stringByAppendingPathComponent:solution.localHDURL];

if (!view) 

    view = [[AsyncImageView alloc] initWithFrame:self.view.bounds];
    view.contentMode = UIViewContentModeScaleAspectFit;

    UIPinchGestureRecognizer *pinchGesture = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinch:)];
    pinchGesture.cancelsTouchesInView = false;
    UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
    panGesture.cancelsTouchesInView = false;

    pinchGesture.delegate = panGesture.delegate = self;

    [view addGestureRecognizer:pinchGesture];
    [view addGestureRecognizer:panGesture];

    ((AsyncImageView *)view).imageURL = [NSURL fileURLWithPath:pathToHDImage];
 else
    ((AsyncImageView *)view).imageURL = [NSURL fileURLWithPath:pathToHDImage];

问题是我的handlePan: 和handlePinch: 永远不会被调用。我能怎么做？主要目标是为每个 iCarousel 项目视图实现缩放功能。

【参考方案1】：

试试这个代码：

 - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
    
    return YES;
    

我没有测试，但我希望它有所帮助。 如果它不起作用，请查看此link1，然后查看此link2

不幸的是，这没有帮助，没有变化
