ios开发如何判断一个控制器是点击tab得到的还是下一界面返回得到的

Answer 1

view1.tag = 1;

UITapGestureRecognizer *tapGestureRecognizer1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];

[view1 addGestureRecognizer:tapGestureRecognizer];

view2.tag = 2;

UITapGestureRecognizer *tapGestureRecognizer2 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];

[view2 addGestureRecognizer:tapGestureRecognizer2];

- (void)tapped:(UITapGestureRecognizer *)gesture

{

UIView *targetview = gesture.view;

if(targetview.tag == 1) {

}

}
