objective-c - 将 UITapRecognizerController 添加到 UIImageView

Question

我有一个imageview我添加了一个tapRecognizer这样的：

recognizer1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap1)];

UIImageView *crossImage = [[UIImageView alloc] initWithFrame:CGRectMake((jrect.origin.x+jrect.size.width), (jrect.origin.y-20), 30, 30)];
crossImage.image = [UIImage imageNamed:@"cross.png"];
[crossImage addGestureRecognizer:recognizer1];
[self addSubview:crossImage];

handleTap方法：

- (void)handlePan1:(UITapGestureRecognizer *)recognizer
{
    NSLog(@"FV");
}

当我单击图像时，没有任何反应。怎么了？

Answer 1

crossImage.userInteractionEnabled = YES;

您需要启用用户迭代。UIImageView 默认为 NO。
