在项目开发中常常会遇到各种奇葩的需求，尤其是要修改系统的按钮的时候。

这里我总结一下平时修改过的导航条的item，自定义的item

1. 页面title设置：self.title =@"Feebback";

2.返回按钮的修改：方案一：self.navigationItem.backBarButtonItem.title = @"Cancel";//这句话在该页面调用即可

如果方案一不能：则需要在前一个页面之前调用下面的方法：

self.navigationItem.backBarButtonItem=[[UIBarButtonItemalloc] initWithTitle:@"Back"style:UIBarButtonItemStyleBorderedtarget:nilaction:nil];

[self.navigationControllerpushViewController:controller animated:YES];

3.(1)定义leftItem or rightItem：

UIButton *button = [UIButtonbuttonWithType:UIButtonTypeCustom];

UIImage *image = [UIImageimageNamed:@"Image_Nearby_Filter_Icon"];

button.frame =CGRectMake(0,0,kScreenWidth/4, image.size.height);

[button setImageEdgeInsets:UIEdgeInsetsMake(0,60,0,0)];

[button setImage:imageforState:UIControlStateNormal];

[button addTarget:selfaction:@selector(filterItemPressed)forControlEvents:UIControlEventTouchDown];

self.navigationItem.rightBarButtonItem = [[UIBarButtonItemalloc]initWithCustomView:button];

(2)使用系统的item：

UIBarButtonItem *moreItme = [[UIBarButtonItemalloc]initWithImage:[UIImageimageNamed:@"Image_Me_Nav_Icon_More"]style:UIBarButtonItemStyleBorderedtarget:self

action:@selector(moreItemPressed:)];

self.navigationItem.rightBarButtonItem = moreItme;

其他的在以后遇到再继续补充
