iOS夜间模式，换肤，换字体样式

实现方式:
使用通知，需要变肤的控件注册这个监听，收到变化的通知之后改变做出相应的处理。
亲自试过，将近百个的视图一起监听变化，性能还ok。
简单实用好理解
1.定义皮肤配置的管理YHSkinConfigManager和皮肤设置的单元对象SkinItem
YHSkinConfigManager.h和SkinItem .h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
typedef NS_ENUM(NSInteger, kSkinType)
{
/** 背景色*/
kSkinType_bg = 10,
/** 背景色*/
kSkinType_bg_1,
/** 分割线*/
kSkinType_separate,
/** 主标题*/
kSkinType_title_main,
/** 副标题*/
kSkinType_title_sub,
/** 注释字体*/
kSkinType_title_note,
/** 红色字体*/
kSkinType_title_red,
/** 首页segment上的颜色*/
kSkinType_title_segment_home,
/** 导航栏上文字颜色*/
kSkinType_title_navc,
/** 主页顶部菜单的Bg*/
kSkinType_home_head_menu_bg,
/** cell的背景深色*/
kSkinType_cell_bg_dark,
/** cell的背景主页*/
kSkinType_cell_bg_home
这里可以扩展定义

其中UIColor+BBXApp.h是软件中自定义的颜色，大家可以随意设置
SettingManager.h是保存自己软件当前的皮肤类型设置、字体大小设置、字体样式设置。自己去保存设置：）
2.定义一个皮肤控制的类别NSObject+Skin、皮肤颜色控制类SkinColorStyleModule和字体大小样式控制类SkinFontStyleModule

其中UIFont+BBX.h是对字体的特殊设置，我是这样子写的

}
else
{

}

}
else
{

}
}
+(UIFont *)bbxBoldSystemFont:(float)size
{
if([SettingManager shareManager].appFontName)
{
return [self bbxSystemFont:size withFontName:[SettingManager shareManager].appFontName];
}
else
{
return [UIFont boldSystemFontOfSize:[self fontSize:size]];
}
}
+(UIFont *)bbxSystemFont:(float)size withFontName:(NSString *)fontName
{
return [UIFont fontWithName:fontName size:[self fontSize:size]];
}
+ (CGFloat)fontSize:(CGFloat)oldFont
{
switch ([SettingManager shareManager].appFont) {
case FontSize_Normal:
oldFont = oldFont;
break;
case FontSize_Small:
oldFont = oldFont-1;
break;
case FontSize_Smallest:
oldFont = oldFont-2;
break;
case FontSize_Big:
oldFont = oldFont+2;
break;
case FontSize_Biger:
oldFont = oldFont+4;
break;
case FontSize_Bigest:
oldFont = oldFont+6;
break;
default:
break;
}
if([MacroAppInfo isiPhone6P])
{
return oldFont;
}
return oldFont;
}
可以自己控制和扩展。
皮肤设置
运用
比如控制vc的背景颜色变化
self.view.skinColorStyle = [[SkinColorStyleModule alloc] initWithTarget:self.view andBlock:^(SkinColorStyleModule *obj) {
obj.skinBgKey = kSkinType_bg;
}];
设置title的文字颜色和背景变化
titlePop.skinColorStyle = [[SkinColorStyleModule alloc] initWithTarget:titlePop andBlock:^(SkinColorStyleModule *obj) {
obj.skinTitleKey = kSkinType_title_segment_home;
obj.skinBgKey = kSkinType_bg;
}];
设置字体大小样式变化
self.userName.skinFontStyle = [[SkinFontStyleModule alloc] initWithTarget:self.userName andNormalFontSize:14];
好用你就拍拍手

这个app中运用了，欢迎大家支持.
