1.检查版本更新以及自动登录

（1）.宏定义

（2）#define kBundle [NSBundle mainBundle].bundleIdentifier

.检查版本更新

在AppDelegate里面

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

 [self checkGuide];

}

（3）检查更新方法 

//登录界面和首页的切换

- (void)checkGuide

{

    //版本号 新特性界面 是否应该加载

    //1.获取你app的版本号

    NSString *locaVerson = [NSBundle mainBundle].infoDictionary[@"CFBundleVersion"];

    //2.获取 你保存在沙盒中的版本号    

    NSUserDefaults *defauts = [NSUserDefaults standardUserDefaults];

    NSString *saveVersion = [defauts objectForKey:@"saveVerion"];

    //3.判断

    if([saveVersion isEqualToString:locaVerson]){//两者一致

      获取密码

       NSUserDefaults *defauts = [NSUserDefaults standardUserDefaults];

       NSString *passWord = [defauts objectForKey:@"saveVerion"];

        if([defauts objectForKey:kUID] && [defauts objectForKey:kTOKEN]){

        //自动登录

            UUTabBarController * mainVc = [[UUTabBarController alloc]init];

            self.window.rootViewController = mainVc;

        }else{

//        跳到登录界面

            //加载登录界面

            UUPhoNumLoginViewController * loginView=[[UUPhoNumLoginViewController alloc]init];

            UULoginNavController *mainVc=[[UULoginNavController alloc]initWithRootViewController:loginView];

            self.window.rootViewController = mainVc;

        }

    }else{

#warning  把最新的版本号保存下来  ****新版本需要走引导页****

        [defauts setObject:locaVerson forKey:@"saveVerion"];

        [defauts synchronize];

        //加载登录界面

        UUPhoNumLoginViewController * loginView=[[UUPhoNumLoginViewController alloc]init];

        UULoginNavController *mainVc=[[UULoginNavController alloc]initWithRootViewController:loginView];

        self.window.rootViewController = mainVc;

    }

}

2.textField点击别处退出键盘

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{

 [self.view endEditing:YES];

}

3.出来键盘，控制当前视图往上面移动的距离

 [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(changeKeyBoard:) name:UIKeyboardWillShowNotification object:nil];

 [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(changeKeyBoard:) name:UIKeyboardWillHideNotification object:nil];

#pragma mark --相应键盘的通知事件

- (void)changeKeyBoard:(NSNotification *)notification{

    if(self.passWordField){

    NSLog(@"%@",notification);

    //获取userInfo信息

    NSDictionary *userInfo = notification.userInfo;   

    //获取要移动控件的transForm

    CGAffineTransform transForm = self.view.transform;  

    //获取移动的位置 屏幕的高度 - 最终显示的frame的Y = 移动的位置

    //1. 获取键盘最终显示的y

    NSValue *value = http://www.mamicode.com/userInfo[UIKeyboardFrameEndUserInfoKey];

    CGRect endFrame = [value CGRectValue];    

    CGFloat moveY = - (self.view.frame.size.height - endFrame.origin.y);   

    //移动具体移动多少，这里决定

    transForm = CGAffineTransformMakeTranslation(0, 移动的距离);

    //执行动画移动

    [UIView animateWithDuration:[userInfo[UIKeyboardAnimationDurationUserInfoKey] floatValue] animations:^{       

        self.view.transform = transForm;

    }];

    }

}

 4.控制进入一个控制器的导航栏视图的显示与隐藏

-(void)viewWillAppear:(BOOL)animated{

    [super viewWillAppear:animated];

 self.navigationController.navigationBarHidden = YES;

}

-(void)viewWillDisappear:(BOOL)animated{

    [super viewWillDisappear:animated];

    self.navigationController.navigationBarHidden = NO;

}

5.在textField的里面的字体更改时就对自己的是有属性赋值

[self.phoneNumField addTarget:self action:@selector(textChange) forControlEvents:UIControlEventEditingChanged];

 [self.passWordField addTarget:self action:@selector(textChange) forControlEvents:UIControlEventEditingChanged];

-(void)textChange{

    self.userName=self.phoneNumField.text;

    self.passWord=self.passWordField.text;

}

6.获取验证码textField的编写

 UITextField * phoneNumField=[[UITextField alloc]init];

 self.phoneNumField= phoneNumField;

 self.phoneNumField.borderStyle= UITextBorderStyleRoundedRect;

 self.phoneNumField.clearButtonMode = UITextFieldViewModeAlways;  

    UILabel * phoneNumLable = [[UILabel alloc]init];

    UIFont *iconfont = [UIFont fontWithName:@"IconFont" size: 18];

    phoneNumLable.font = iconfont;

    phoneNumLable.text = @"\U0000e602"; 

    UIView *phoneNumview=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 30, 50)];

    self.phoneNumField.leftView=phoneNumview;

    self.phoneNumview = phoneNumview ;

    phoneNumLable.frame = CGRectMake(10, 0, 30, 50);

    [self.phoneNumview addSubview:phoneNumLable];   

    self.phoneNumField.leftViewMode = UITextFieldViewModeAlways;

UITextField * passWordField=[[UITextField alloc]init];

    self.passWordField= passWordField;

    self.passWordField.placeholder=@"验证码";

   UIButton * verCodeBtn = [[UIButton alloc]init];

    self.passWordField.rightView = verCodeBtn;

    self.passWordField.rightViewMode = UITextFieldViewModeAlways;

这样，我们就可以很方便的使用iconfont图标了。这里要注意的是，图标是用的iconfont中的图标用的是unicode编码，我们在自己的工程中时需要将&#xXXXX格式转换成\UXXXXXXXX格式。

-(void)loadView{    [super loadView];//    imageView    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 50, 30, 30)];    [self.view addSubview:imageView];//图标编码是&#xe603，需要转成\U0000e603    imageView.image = [UIImage iconWithInfo:TBCityIconInfoMake(@"\U0000e603", 30, [UIColor redColor])];//    button    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];    button.frame = CGRectMake(100, 100, 40, 40);    [self.view addSubview:button];    [button setImage:[UIImage iconWithInfo:TBCityIconInfoMake(@"\U0000e60c", 40, [UIColor redColor])] forState:UIControlStateNormal];//    label,label可以将文字与图标结合一起，直接用label的text属性将图标显示出来    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(50, 160, 280, 40)];    [self.view addSubview:label];    label.font = [UIFont fontWithName:@"iconfont" size:15];//设置label的字体    label.text = @"这是用label显示的iconfont  \U0000e60c";}

- (void)viewDidLoad {    [super viewDidLoad];    self.view.backgroundColor = [UIColor whiteColor];    self.navigationController.navigationBar.translucent = NO;    UIBarButtonItem *leftBarButton = [[UIBarButtonItem alloc] initWithImage:[ UIImage iconWithInfo:TBCityIconInfoMake(@"\U0000e602",22,[UIColor colorWithRed:0.55 green:0.55 blue:0.55 alpha:1])] style:UIBarButtonItemStylePlain target:self action:@selector(leftButtonAction)];    self.navigationItem.leftBarButtonItem = leftBarButton;    self.navigationItem.leftBarButtonItem.tintColor = [UIColor colorWithRed:0.55 green:0.55 blue:0.55 alpha:1];    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage iconWithInfo:TBCityIconInfoMake(@"\U0000e60d",25, [UIColor colorWithRed:0.14 green:0.61 blue:0.83 alpha:1.00])] style:UIBarButtonItemStylePlain target:self action:@selector(rightButtonAction)];     self.navigationItem.rightBarButtonItem.tintColor = [UIColor colorWithRed:0.14 green:0.61 blue:0.83 alpha:1.00];    // Do any additional setup after loading the view, typically from a nib.}
