(作者比较懒,喜欢用iOS自带属性修饰控件,喜欢自定义或重写的朋友请绕行)

一.自定义navigation外观

先准备背景图片navigation

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

//改变navigationcontroller背景(青色)

[self.navigationController.navigationBar setBackgroundImage:imageforBarMetrics:UIBarMetricsDefault];

UIBarButtonItem *back = [[UIBarButtonItem alloc]initWithTitle:@"back"style:UIBarButtonItemStyleBorderedtarget:self action:@selector(back:)];

//backButton背景颜色(back按钮背景黄色)

back.tintColor = [UIColor yellowColor];

self.navigationItem.backBarButtonItem = back;

UIBarButtonItem *right = [[UIBarButtonItem alloc]initWithTitle:@"next" style:UIBarButtonItemStyleBordered target: self action:@selector(next:)];

//改变right背景颜色(next按钮背景绿色)

right.tintColor = [UIColor greenColor];

self.navigationItem.rightBarButtonItem = right;

// NSArray *fontsArr = [UIFont familyNames];//打印所有字体

//navigation标题(棕色brownColor)(字典依次为标题(餐饮,种类)字体颜色,阴影颜色,阴影范围,字体,字体大小)

[self.navigationController.navigationBarsetTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:[UIColorbrownColor],UITextAttributeTextColor, [UIColorcolorWithRed:0 green:0blue:0alpha:0.8],UITextAttributeTextShadowColor,[NSValuevalueWithUIOffset:UIOffsetMake(0.5, 0.5)],UITextAttributeTextShadowOffset,[UIFontfontWithName:@"Times New Roman"size:24.0f],UITextAttributeFont,nil]];

//定制应用中所有导航栏有barButttonItem按钮 appearance(字典依次为标题(next,back)字体颜色,阴影颜色,阴影范围,字体,字体大小)

[[UIBarButtonItem appearance] setTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:

[UIColor redColor ],UITextAttributeTextColor,[UIColorcolorWithRed:0green:0 blue:0alpha:0.8],UITextAttributeTextShadowColor,[NSValuevalueWithUIOffset:UIOffsetMake(1.5, 1.5)],UITextAttributeTextShadowOffset,[UIFontfontWithName:@"Times New Roman"size:20],UITextAttributeFont,nil]forState:UIControlStateNormal ];

有图有真相:(为了显示阴影效果偏移量UIOffsetMake(1.5, 1.5)比较,自己调小即可,红色为按钮标题颜色,黑色(alpha:0.8)为阴影)

二.图片+手势也可完成navigationController同样功能
