使用StoryBoard:用Segue传递数据

A---》B

想把数据  NSString A_data   从AController传到BController,则在BController中  @property 一个NSString data ,然后在AController中添加方法

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
UIViewController *destination = segue.destinationViewController;
if ([destination respondsToSelector:@selector(setData:)]) {
[destination setValue:A_data forKey:@"data"];
}

}
