StoryBoard获取不同id的Controller
ViewController *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"list"];
获取plist文件中数据
NSBundle *bundle = [NSBundle mainBundle]; NSString *plistPath = [bundle pathForResource:@"team" ofType:@"plist"]; // 获取属性列表文件中的全部数据 self.listTeams = [[NSArray alloc] initWithContentsOfFile:plistPath];
