ios换肤思想,及工具类

// 实现原理及思路:不同种类的皮肤放在不同的文件夹下,用一个plist文件存放不同控制器下的控件的背景颜色

//plist文件名称为控制器的名称,内部的数据字典的key value对自定义一个命名规则,容易读取即可

//

 

#import "MYScreenToll.h"

 

@interface MYScreenToll ()

 

 

 

@end

 

//皮肤设置

static NSString*_skin;

 

@implementation MYScreenToll

 

//类初始化加载的时候调用

+(void)initialize

{

    _skin=[[NSUserDefaults standardUserDefaults]objectForKey:@"skin1"];

    if (_skin==nil) {

        _skin=@"blue";

    }

}

 

//类方法

+(void)saveSkin:(NSString*)skin

{

    _skin=skin;

    //保存

    NSUserDefaults *user=[NSUserDefaults standardUserDefaults];

    [user setObject:skin forKey:@"skin1"];

    [user synchronize];

}

 

+(UIImage*)loadImage:(NSString*)imageName

{

    NSString*pathName=[NSString stringWithFormat:@"skin/%@/%@",_skin,imageName];

    UIImage *image=[UIImage imageNamed:pathName];

    return image;

}

 

+(UIColor*)loadColor:(NSString*)key

{

    //拼接路径

    NSString *plistName=[NSString stringWithFormat:@"skin/%@/color.plist",_skin];

    //读取plist文件

    NSString*str=[[NSBundle mainBundle]pathForResource:plistName ofType:nil];

    NSData *data=[NSData dataWithContentsOfFile:str];

    NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];

    NSString*colorStr=[dict objectForKey:key];

    NSArray *rgb=[colorStr componentsSeparatedByString:@","];

    UIColor *col=[[UIColor alloc]initWithRed:[rgb[0] intValue]/255.0 green:[rgb[1] intValue]/255.0 blue:[rgb[2] intValue]/255.0 alpha:1];

    return col;
