UISearchBar的簡單實用

在NavigtionBar上創建搜索框UISearchBar

    self.searchEpisdose = [[UISearchBaralloc]initWithFrame:CGRectMake(60,25,200,30)];

    self.searchEpisdose.placeholder =@"請輸入要搜索的關鍵字";

    self.searchEpisdose.barTintColor = [UIColorgrayColor];

    self.searchEpisdose.layer.cornerRadius =15;//設置圓角

    self.searchEpisdose.delegate =self;//設置代理

    UIView * titleView = [[UIViewalloc]initWithFrame:CGRectMake(50,25,220, 30)];//創建titleView

    [titleView addSubview:self.searchEpisdose];

    self.navigationItem.titleView =self.searchEpisdose;//將創建搜索框sreachBar指定給titleView
