代码出处cocoachina

必须包含文件是HPThemeManager.h和HPThemeManager.m

再HPThemeManager.h里申明一个主题的字典，主题索引和当前主题

  NSDictionary *themeDictionary;  NSInteger currentThemeIndex;  NSString *currentTheme;

在HPThemeManager.m里初始化主题

-(id)init{  self = [super init];  if(self)  {    NSString *path = [[NSBundle mainBundle] pathForResource:@"themes" ofType:@"plist"];    themeDictionary = [[NSDictionary alloc] initWithContentsOfFile:path];    self.currentThemeIndex = 0;    self.currentTheme = @"maroon"; //default theme  }  return self;}

在resourece文件夹里添加了名为themes的plist文件，里面存放主题名。

设置初始主题为maroon

每次加载主题的素材时都从目录加载

-(void)updateTheme:(NSNotification*)notif{    NSString *themename = [HPThemeManager sharedThemeManager].currentTheme;    NSString *themePathTmp = [[[HPThemeManager sharedThemeManager] themeDictionary] objectForKey:themename];    NSString *themePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:themePathTmp];    if(themePath){        settingTable.backgroundView = [[UIImageView alloc]initWithImage:[UIImage imageWithContentsOfFile:[themePath stringByAppendingPathComponent:@"background.png"]]];        [backButton setImage:[UIImage imageWithContentsOfFile:[themePath stringByAppendingPathComponent:@"back.png"]] forState:UIControlStateNormal];        navback.image = [UIImage imageWithContentsOfFile:[themePath stringByAppendingPathComponent:@"nav.png"]];    }    NSLog(@"%@",themePath);}

在选择主题的tableview中加如下代码

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {  NSString *selectName = [themes objectAtIndex:indexPath.row];  [[HPThemeManager sharedThemeManager] setCurrentTheme:selectName]; //must set before post  [[HPThemeManager sharedThemeManager] setCurrentThemeIndex:indexPath.row];    [[NSNotificationCenter defaultCenter] postNotificationName:kThemeDidChangeNotification                                                       object:nil                                                     userInfo:[NSDictionary dictionaryWithObject:selectName forKey:@"selectedTheme"]];  //[tableView deselectRowAtIndexPath:indexPath animated:YES];}

在放入主题素材的文件夹时一定要将整个文件夹加入
