不兼容的指针类型将“UITapGestureRecognizer *”发送到“UIView * _Nonnull”类型的参数答案

【问题标题】：Incompatible pointer types sending 'UITapGestureRecognizer *' to parameter of type 'UIView * _Nonnull'不兼容的指针类型将“UITapGestureRecognizer *”发送到“UIView * _Nonnull”类型的参数
【发布时间】：2015-10-23 08:27:45
【问题描述】：

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：

不兼容的指针类型发送“UITapGestureRecognizer *”到 'UIView * _Nonnull' 类型的参数

【解决方案1】：

您应该使用 addGestureRecognizer 向 UI 对象添加手势

// [self.fullScreenImageView addSubview:tapGestureRecognizer];

[self.fullScreenImageView addGestureRecognizer: tapGestureRecognizer];

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； [自我 addSubview:self.fullScreenImageView];喜欢你的

【解决方案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];

这就是解决方案。我找到了谢谢@anhtu
