ios - 自定义导航栏后退按钮点击区域

Question

我已经实现了自定义后退导航栏按钮。

代码:

-(UIBarButtonItem *)logicToAddBackButton {

UIImageView *imageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"UiNavigationBack"]];

UILabel *label=[[UILabel alloc] init];

[label setTextColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0]];
[label setText:@"Home"];
[label sizeToFit];

int space=6;
label.frame=CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+space, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, label.frame.size.width+imageView.frame.size.width+space, imageView.frame.size.height)];

view.bounds=CGRectMake(view.bounds.origin.x+8, view.bounds.origin.y-1, view.bounds.size.width, view.bounds.size.height);
[view addSubview:imageView];
[view addSubview:label];

UIButton *button=[[UIButton alloc] initWithFrame:view.frame];
[button addTarget:self action:@selector(eventBack) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:button];

[UIView animateWithDuration:0.33 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
    label.alpha = 0.0;
    CGRect orig=label.frame;
    label.frame=CGRectMake(label.frame.origin.x+25, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
    label.alpha = 1.0;
    label.frame=orig;
} completion:nil];

UIBarButtonItem *backButton =[[UIBarButtonItem alloc] initWithCustomView:view];

return backButton;

}

self.navigationItem.leftBarButtonItem = [self logicToAddBackButton];

根据逻辑，这是它的外观和工作方式。

问题:如果单击箭头的前半部分，则后退按钮不响应。

请对此提出建议。

尝试设置为您的按钮:

button.contentEdgeInsets = UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)
