不兼容的指针类型发送＆＃39; UITapGestureRecognizer *＆＃39;参数类型＆＃39; UIView * _Nonnull＆＃39;

Question

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGestureAction)];
tapGestureRecognizer.numberOfTapsRequired = 1;

self.fullScreenImageView = [[UIImageView alloc]initWithFrame:self.frame];
self.fullScreenImageView.image = [UIImage imageNamed:@"family"];
self.fullScreenImageView.userInteractionEnabled = YES;
[self addSubview:self.fullScreenImageView];
[self.fullScreenImageView addSubview:tapGestureRecognizer];

这些代码有什么问题。
Xcode 7.0给出了这个错误：

Answer 1

您应该使用addGestureRecognizer向UI对象添加手势

// [self.fullScreenImageView addSubview:tapGestureRecognizer];

[self.fullScreenImageView addGestureRecognizer: tapGestureRecognizer];

Answer 2

    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapGestureAction)];
    tapGestureRecognizer.numberOfTapsRequired = 1;
    [self addGestureRecognizer:tapGestureRecognizer];

    self.fullScreenImageView = [[UIImageView alloc]initWithFrame:self.frame];
    self.fullScreenImageView.image = [UIImage imageNamed:@"family"];
    self.fullScreenImageView.userInteractionEnabled = YES;
    [self addSubview:self.fullScreenImageView];

这是解决方案。我发现了感谢@anhtu
