lz是Ios新手,在草鸟教程学习ios控件使用，但是又有菜鸟教程的代码不给了，部分代码缺失，所以lz无法看全代码，部分功能无法实现，于是在网站找了半天(哎呀，我的暴脾气➡️发作了)终于在网站找到了lz要的功能代码，过来纪录一下

.h文件

@property(nonatomic,strong)IBOutlet UITextField *TF_departement;@property(nonatomic,strong)IBOutlet UITextField *TF_post;//下拉框类表@property(nonatomic,strong)IBOutlet UIPickerView *PV_departement;@property(nonatomic,strong)IBOutlet UIPickerView *PV_post;@property(nonatomic,strong)NSArray *departement_list;@property(nonatomic,strong)NSArray *post_list;

.m文件代码

    self.PV_post = [[UIPickerView alloc]init];    self.PV_post.delegate = self;    self.PV_post.dataSource = self;    self.PV_post.showsSelectionIndicator = YES;    self.TF_post.delegate = self;    self.TF_post.inputView = self.PV_post;        UIButton *myButton = [[UIButton alloc] init];    [myButton setBackgroundColor:[UIColor hexstringToColor:@"0099FF"]];    myButton.titleLabel.font = [UIFont systemFontOfSize:14.0];    [myButton setFrame:CGRectMake(0, 0, 80, 30)];    [myButton setTitle:@"Done" forState:UIControlStateNormal];    [myButton addTarget:self action:@selector(hiddenPickerView:) forControlEvents:UIControlEventTouchUpInside];    UIBarButtonItem *sure_btn = [[UIBarButtonItem alloc] initWithCustomView:myButton];    UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - self.PV_departement.frame.size.height-50, 320, 50)];    [toolBar setBarStyle:UIBarStyleBlackOpaque];    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];    NSArray *toolbarItems = [NSArray arrayWithObjects:flexSpace,sure_btn,nil];    [toolBar setItems:toolbarItems];    self.TF_post.inputAccessoryView = toolBar;

-(void)hiddenPickerView:(id)sender{    [self.view endEditing:true];}
