使导航栏标题单击目标C iOS 10.2

Question

是否有任何方法可以单击导航栏标题？我没有任何特定的导航栏类。我控制着ViewController的所有内容。如果有办法，我很想知道。我一直在寻找一个白色，但找不到合适的答案。

Answer 1

导航栏上的按钮

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
           action:@selector(btnclick:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Title" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, self.view.frame.size.width, 64.0);
self.navigationItem.titleView =button;
-(void)btnclick:(id)sender
{ NSLog(@"button click");
}

Answer 2

您可以尝试以这种方式尝试

UIView *topView = [[UIView alloc]initWithFrame:CGRectZero];
UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero];
[button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Title here" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button sizeToFit];
[topView addSubview:button];
[topView sizeToFit];
self.navigationItem.titleView = topView;
-(void)buttonAction:(Id) sender
{
 NSLog(@"button clicked");
}
