ThemeManager主题切换（1）

主题包文件：使用实体文件拖入Xcode





主题包plist文件：



主题类.h

#import <Foundation/Foundation.h>

//通知名称
#define ThemeNameChange @"ThemeNameChange"

//默认主题
#define ThemeDefault @"bluemoon"

//保存到本地的key
#define kThemeName @"kThemeName"

@interface ThemeManager : NSObject

/**单例*/
+ (ThemeManager *)shareInstance;

/**当前主题*/
@property(nonatomic, copy)NSString *themeName;

/**主题图片字典*/
@property(nonatomic, strong)NSDictionary *themeDic;

/**主题字体颜色字典*/
@property (nonatomic ,strong) NSDictionary *fontColorDic;

/**根据当前的需要的图片名获取图片*/
- (UIImage *)getThemeImg:(NSString *)imgName;
/**根据传入的key获取RGB颜色*/
- (UIColor *)getThemeColor:(NSString *)colorKeyName;

/**保存主题*/
- (void)saveTheme;

@end

主题类.m

@implementation ThemeManager

//1.定义一个单例 返回一个主题管理对象
+ (ThemeManager *)shareInstance {

static dispatch_once_t onceToken;
static ThemeManager *instance = nil;
dispatch_once(&onceToken, ^{
instance = [[self alloc] init];

//2.在对象初始化的时候,设置默认主题、读取本地存取的主题、读取plist内容存入属性字典
- (instancetype)init

UIImageView子类化及使用

XLUIImageView.h

@interface XLUIImageView : UIImageView

@property (nonatomic ,copy) NSString *imgName;

@end

XLUIImageView.m

#import "XLUIImageView.h"
#import "ThemeManager.h"

@implementation XLUIImageView

- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadView) name:ThemeNameChange object:nil];

}

return self;
}

- (void)awakeFromNib
{
[super awakeFromNib];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadView) name:ThemeNameChange object:nil];

}

- (void)setImgName:(NSString *)imgName
{
if (_imgName != imgName) {

_imgName = imgName;

[self loadView];

}
}

- (void)loadView
{
self.image = [[ThemeManager shareManager] getThemeImg:_imgName];
}

@end

使用：
_selectedImage.imgName = @"home_bottom_tab_arrow.png";
_tabBarView.imgName = @"mask_navbar.png";

UIButton子类化

XLUIButton.h

@interface XLUIButton : UIButton

@property (nonatomic, copy) NSString *normalImage;
@property (nonatomic ,copy) NSString *highlightedImage;
@property (nonatomic ,copy) NSString *normalBgImage;
@property (nonatomic ,copy) NSString *highlightedBgImage;

@end

XLUIButton.m

#import "XLUIButton.h"
#import "ThemeManager.h"

@implementation XLUIButton

- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:ThemeNameChange object:nil];
}

- (instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadImage) name:ThemeNameChange object:nil];

}

return self;
}

- (void)awakeFromNib
{
[self awakeFromNib];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadImage) name:ThemeNameChange object:nil];
}

- (void)setNormalImage:(NSString *)normalImage
{
if (_normalImage != normalImage) {

_normalImage = normalImage;

[self loadImage];
}
}
- (void)setNormalBgImage:(NSString *)normalBgImage
{
if (_normalBgImage != normalBgImage) {

_normalBgImage = normalBgImage;

[self loadImage];
}
}
- (void)setHighlightedImage:(NSString *)highlightedImage
{
if (_highlightedImage != highlightedImage) {

_highlightedImage = highlightedImage;

[self loadImage];
}
}
- (void)setHighlightedBgImage:(NSString *)highlightedBgImage
{
if (_highlightedBgImage != highlightedBgImage) {

_highlightedBgImage = highlightedBgImage;

[self loadImage];
}
}

- (void)loadImage
{
ThemeManager *theme = [ThemeManager shareManager];

UIImage *norImg = [theme getThemeImg:self.normalImage];
UIImage *norBgImg = [theme getThemeImg:self.normalBgImage];
UIImage *highImg = [theme getThemeImg:self.highlightedImage];
UIImage *hightBgImg = [theme getThemeImg:self.highlightedBgImage];

if (norImg) {
[self setImage:norImg forState:UIControlStateNormal];
}

if (norBgImg) {
[self setImage:norBgImg forState:UIControlStateNormal];
}

if (highImg) {
[self setImage:highImg forState:UIControlStateHighlighted];
}

if (hightBgImg) {
[self setImage:hightBgImg forState:UIControlStateHighlighted];
}

}
@end

XLUIButton的使用
XLUIButton *button = [[XLUIButton alloc] initWithFrame:CGRectMake(buttonX, buttonY, buttonW, buttonH)];

//设置默认状态的图片
button.normalImage = btnImage[i];

UILable子类化

XLUILable.h

@interface XLUILable : UILabel

@property (nonatomic ,copy) NSString *colorName;

@end

XLUILable.m

#import "XLUILable.h"
#import "ThemeManager.h"

@implementation XLUILable

- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:ThemeNameChange object:nil];
}

- (instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {
//        接收通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadColor) name:ThemeNameChange object:nil];
}
return self;
}

- (void)awakeFromNib
{
[super awakeFromNib];
//        接收通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loadColor) name:ThemeNameChange object:nil];
}

- (void)setColorName:(NSString *)colorName
{
if (_colorName != colorName) {
_colorName = colorName;

[self loadColor];
}
}

- (void)loadColor
{

self.textColor = [[ThemeManager shareManager] getThemeColor:_colorName];
}

@end

XLUILable使用

XLUILable *lable = [[XLUILable alloc] initWithFrame:CGRectMake(10, 50, 200, 80)];
[self.view addSubview:lable];
lable.colorName = @"Mask_Title_color";
lable.text = @"11111";

导航栏和基类viewController的图片和字体颜色的设置

- (void)viewDidLoad {
[super viewDidLoad];

[self colorChang];

}

- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:ThemeNameChange object:nil];
}

- (instancetype)initWithCoder:(NSCoder *)aDecoder
{
if (self = [super initWithCoder:aDecoder]) {

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(colorChang) name:ThemeNameChange object:nil];

}
return self;
}

- (void)colorChang
{
NSString *image = nil;

if (iOS7) {
image = @"mask_titlebar64@2x.png";
}else{
image = @"mask_titlebar@2x.png";
}

//获取图片
UIImage *img = [[ThemeManager shareManager] getThemeImg:image];

//设置背景图片
[self.navigationBar setBackgroundImage:img forBarMetrics:UIBarMetricsDefault];

//设置字体颜色
UIColor *color = [[ThemeManager shareManager] getThemeColor:@"Mask_Title_color"];

NSDictionary *attrDict = @{
NSFontAttributeName: [UIFont fontWithName: @"Zapfino" size: 20],
NSForegroundColorAttributeName: color
};

self.navigationBar.titleTextAttributes = attrDict;

}

@implementation BaseViewController

- (void)viewDidLoad {
[super viewDidLoad];

//初始化时设置默认主题背景图片
[self bgColorChang];
}

//删除通知
- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self name:ThemeNameChange object:nil];
}

//通过storyboard创建控制器时调用
- (instancetype)initWithCoder:(NSCoder *)aDecoder
{
if (self = [super initWithCoder:aDecoder]) {

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(bgColorChang) name:ThemeNameChange object:nil];

}

return self;
}

//通知触发方法
- (void)bgColorChang
{
ThemeManager *theme = [ThemeManager shareManager];

self.view.backgroundColor = [UIColor colorWithPatternImage:[theme getThemeImg:@"bg_home.jpg"]];
