问个 UITapGestureRecognizer 的小白问题，关于每次 tap 后 index 递增
binarymann · 2014-05-20 14:20:52 +08:00 · 2082 次点击这是一个创建于 3842 天前的主题，其中的信息可能已经有所发展或是发生改变。
在viewDidLoad中:
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hanldeTap:)];
[self.view addGestureRecognizer:tap];
处理点击事件的方法
- (void)hanldeTap:(UITapGestureRecognizer *)gr
{
NSUInteger index = 1;
index++;
NSLog(@"%d", index);
}
为何我点击后index都不递增呢？NSLog出来的值都是2，肯定是我没有将方法调用对
