在开发中常常会遇到换肤的情况，如果每次都用一个判断语句去修改图片会相当的麻烦，为了工作需要我进行了深入研究找到一种方法。
1、创建两个bundle来存放资源文件，里面包含plist文件和图片
把所需要的图片放进去，plist文件中写对应的颜色
2、写一个配置文件来集中处理图片和颜色
#import "DDSkin.h"
#define SkinColor @"DDDkinColor"
@implementation DDSkin
static NSString *_color;
+ (void)initialize {
// 开始，从沙盒中取之前存储的皮肤颜色
_color = [[NSUserDefaults standardUserDefaults] objectForKey:SkinColor];
if (_color == nil) { // 之前没有存储，取出为空，默认为蓝色
_color = @"blue";
}
}
/**
* 通过该方法可以设置皮肤的颜色
*
* @param color 皮肤的颜色
*/
+ (void)setSkinColor:(NSString *)color {
_color = color;
// 将用户设置的皮肤颜色进行保存
[[NSUserDefaults standardUserDefaults] setObject:color forKey:SkinColor];
[[NSUserDefaults standardUserDefaults] synchronize];
}
/**
* 通过该方法,可以返回想要的UIImage
*
* @param name 图片的名称
*
* @return 当前皮肤对应的UIImage
*/
+ (UIImage *)ddSkinWithImageName:(NSString *)name {
NSString *path = [[NSBundle mainBundle] pathForResource:_color ofType:@"bundle"];
NSString *imagePath = [path stringByAppendingString:[NSString stringWithFormat:@"/%@",name]];
return [[UIImage alloc] initWithContentsOfFile:imagePath];
}
/**
* 返回当前皮肤的Label背景颜色
*
* @return 当前的背景颜色
*/
+ (UIColor *)ddSkinWithColorName:(NSString *)name {
// 1.获取文件夹位置
NSString *path = [[NSBundle mainBundle] pathForResource:_color ofType:@"bundle"];
//获取文件位置
NSString *plistPath = [path stringByAppendingString:@"/color.plist"];
//读取plist当中的数据
NSDictionary *colorDict = [NSDictionary dictionaryWithContentsOfFile:plistPath];
//将字典当中的值取出
NSString *bgStr = [colorDict objectForKey:name];
//将颜色的字符串截取
NSArray *bgArray = [bgStr componentsSeparatedByString:@","];
//取出颜色的r,g,b数值
CGFloat red = [bgArray[0] floatValue];
CGFloat green = [bgArray[1] floatValue];
CGFloat blue = [bgArray[2] floatValue];
//返回当前皮肤的颜色
return [UIColor colorWithRed:red/255.0 green:green/255.0 blue:blue/255.0 alpha:1.0];
}
@end
3、调用的方法
- (void)viewDidLoad {
[super viewDidLoad];
[self.ragBurron addTarget:self action:@selector(ragButtonTouch) forControlEvents:UIControlEventTouchUpInside];
[self.blueButton addTarget:self action:@selector(blueButtonTouch) forControlEvents:UIControlEventTouchUpInside];
self.blackView.backgroundColor = [DDSkin ddSkinWithColorName:@"color"];
self.imageView.image = [DDSkin ddSkinWithImageName:@"xianxian.jpg"];
}
- (void)ragButtonTouch {
[DDSkin setSkinColor:@"rad"];
self.blackView.backgroundColor = [DDSkin ddSkinWithColorName:@"color"];
self.imageView.image = [DDSkin ddSkinWithImageName:@"xianxian.jpg"];
}
- (void)blueButtonTouch {
[DDSkin setSkinColor:@"blue"];
self.blackView.backgroundColor = [DDSkin ddSkinWithColorName:@"color"];
self.imageView.image = [DDSkin ddSkinWithImageName:@"xianxian.jpg"];
}
