跳转逻辑
左边控制器
代码示例:
#pragma mark- 设置就会调用
- (void)setting:(UIButton *)btn{
/*
1. 底部条没有隐藏
2. 处理返回按钮的样式：2.1去设置控制器去设置
*/
// 跳转到设置界面
ZYSettingTabViewController *settingVc = [[ZYSettingTabViewController alloc]init];
// 当push的时候隐藏tabBar
// 必须在跳转之前去设置
settingVc.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:settingVc animated:YES];
}
右边控制器
#import "ZYSettingTabViewController.h"
@interface ZYSettingTabViewController ()
@end
@implementation ZYSettingTabViewController
- (void)viewDidLoad {
[super viewDidLoad]
self.navigationItem.leftBarButtonItem = [UIBarButtonItem backItemWithNorImage:@"navigationButtonReturn"
highImage:@"navigationButtonReturnClick"
target:self
action:@selector(back)
title:@"返回"];
}
#pragma mark- 返回按钮
- (void)back
{
[self.navigationController popViewControllerAnimated:YES];
}
对返回按钮的封装
+ (instancetype)backItemWithNorImage:(NSString *)norImage
highImage:(NSString *)highImage
target:(id)target
action:(SEL)action
title:(NSString *)title
{
// 设置导航条左边按钮
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
// 文字
[backButton setTitle:title forState:UIControlStateNormal];
// 图片
[backButton setImage:[UIImage imageNamed:norImage] forState:UIControlStateNormal];
[backButton setImage:[UIImage imageNamed:highImage] forState:UIControlStateHighlighted];
// 文字颜色
[backButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[backButton setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
// 根据内容适配尺寸
[backButton sizeToFit];
// 设置左边按钮离边距的距离
backButton.contentEdgeInsets = UIEdgeInsetsMake(0, -20, 0, 0);
// 添加点击事件
[backButton addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
// 设置左边按钮
return [[UIBarButtonItem alloc]initWithCustomView:backButton];
}
设置全局返回按钮
- 我们发现只有在push的时候，改变栈顶控制器的返回按钮，即可。
重写push方法，进行拦截。
/*重写push方法进行拦截--设置全局返回按钮/
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if (self.childViewControllers.count > 0) {// 非根控制器
// 设置返回按钮，只有非根控制器，才有返回按钮（tabBar有几个子控制器）
viewController.navigationItem.leftBarButtonItem = [UIBarButtonItem backItemWithNorImage:@"navigationButtonReturn"highImage:@"navigationButtonReturnClick" target:self action:@selector(back) title:@"返回"];
}
// 真正的跳转
[super pushViewController:viewController animated:animated];
}
#pragma mark- 点击事件
- (void)back
{
[self popViewControllerAnimated:YES];
}
