如何在界面中使用自定义UIBarButtonItem全部使用自定义UINavigationBar

不在每个界面中再次写入。

统一设置是否有统一的方法？

UIImage image = [UIImage imageNamed:imagePath];
UIButton button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height);
[button setImage:image forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:highLightImagePath] forState:UIControlStateHighlighted];
[button addTarget:self action:selector forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

很多接口backBarButtonItem需要自定义，代码是一样的，我不想写N次

您可以在单个全局变量文件中添加它，例如

GlobalVariable.h

+(UIBarButtonItem*)customButton;

GlobalVariable.m

+(UIBarButtonItem*)customButton{
    UIImage *image = [UIImage imageNamed:imagePath];
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.frame = CGRectMake(0, 0, image.size.width, image.size.height);
    [button setImage:image forState:UIControlStateNormal];
    [button setImage:[UIImage imageNamed:highLightImagePath] forState:UIControlStateHighlighted];
    [button addTarget:self action:selector forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem* btn = [[UIBarButtonItem alloc] initWithCustomView:button];
    return btn;
}

然后，在您希望按钮显示的视图中导入GlobalVariable.h并调用

self.navigationItem.leftBarButtonItem = [GlobalVariable customButton];

如果您还需要其他变量，可以将GlobalVariable保留在那里。
