一、个人中心未登录
方法:
加判断登录状态直接打开个人中心页面4，否则出现上面引导登录或注册入口显示
代码如下:
#pragma mark addView- (void)addView{//背景图[self.view setBackgroundColor:[UIColor whiteColor]];UIImageView *loginImgTips = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"login_tips.png"]];loginImgTips.frame = CGRectMake(33, 31, 255, 135);[self.view addSubview:loginImgTips];[loginImgTips release];//登录、注册提示UILabel *loginLab = [[UILabel alloc] initWithFrame:CGRectMake(55, 43, 199, 80)];[loginLab setText:@"登录工程师爸爸，网站收藏、iPhone下载、可方便哩!"];[loginLab setTextColor:[UIColor blackColor]];[loginLab setBackgroundColor:[UIColor clearColor]];[loginLab setNumberOfLines:3];[loginLab setFont:[UIFont systemFontOfSize:18]];[self.view addSubview:loginLab];[loginLab release];//登录UIButton *loginBtn = [[UIButton alloc] initWithFrame:CGRectMake(37, 180, 117, 37)];[loginBtn setBackgroundImage:[UIImage imageNamed:@"Button_login.png"] forState:UIControlStateNormal];[loginBtn setBackgroundImage:[UIImage imageNamed:@"Button_login@2x.png"] forState:UIControlStateHighlighted];[loginBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];[loginBtn setTag:101];[self.view addSubview:loginBtn];[loginBtn release];//注册UIButton *registerBtn = [[UIButton alloc] initWithFrame:CGRectMake(164, 180, 117, 37)];[registerBtn setBackgroundImage:[UIImage imageNamed:@"Button_reg.png"] forState:UIControlStateNormal];[registerBtn setBackgroundImage:[UIImage imageNamed:@"Button_reg@2x.png"] forState:UIControlStateHighlighted];[registerBtn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];[registerBtn setTag:102];[self.view addSubview:registerBtn];[registerBtn release];}
二、登录
顶部导航代码：
#pragma mark addNavBar-(void) addNavBar{//返回按钮UIButton *btnLeft = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 24, 24)];[btnLeft setBackgroundImage:[UIImage imageNamed:@"item_back.png"] forState:UIControlStateNormal];[btnLeft setBackgroundImage:[UIImage imageNamed:@"item_back@2x.png"] forState:UIControlStateHighlighted];[btnLeft setTag:101];[btnLeft.titleLabel setFont:[UIFont boldSystemFontOfSize:14]];[btnLeft addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];UIBarButtonItem *navBarBack = [[UIBarButtonItem alloc] initWithCustomView:btnLeft];[btnLeft release];[self.navigationItem setLeftBarButtonItem:navBarBack];[navBarBack release];//右侧完成UIBarButtonItem *navBarFinish = [[UIBarButtonItem alloc] initWithTitle:@"注册" style:UIBarButtonItemStyleDone target:self action:@selector(btnClick:)];navBarFinish.tag = 102;self.navigationItem.rightBarButtonItem = navBarFinish;[navBarFinish release];}
登录界面代码实现如下:
#pragma mark addView//创建输入框- (void)addInput{//基本参数定义CGFloat padx = 80.0f;_vFrame= CGRectMake(10, 14, 300, 80);UIFont *lpFont = [UIFont boldSystemFontOfSize:16];//邮箱和密码背景颜色设置_view = [[UIView alloc] initWithFrame:_vFrame];_view.layer.cornerRadius = 8.0;_view.layer.borderWidth = 1;_view.layer.borderColor = [UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f].CGColor;[_view setBackgroundColor:[UIColor colorWithRed:247.0f/255.0f green:247.0f/255.0f blue:247.0f/255.0f alpha:1.0f]];[self.view addSubview:_view];[_view release];//邮箱与密码中间分割线UIView *line = [[UIView alloc] initWithFrame:CGRectMake(10, 55, 300, 1)];[line setBackgroundColor:[UIColor colorWithRed:209.0f/255.0f green:209.0f/255.0f blue:209.0f/255.0f alpha:1.0f]];[self.view addSubview:line];[line release];//用户名或EmailUIImageView * _eview = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 250, 40)];[_eview setUserInteractionEnabled:YES];[_view addSubview:_eview];[_eview release];UILabel *_unameLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 5, 55, 40)];[_unameLab setText:@"用户名"];_unameLab.highlighted = YES;_unameLab.highlightedTextColor = [UIColor blackColor];[_unameLab setFont:lpFont];[_unameLab setBackgroundColor:[UIColor clearColor]];[_unameLab setTextColor:[UIColor blackColor]];[_view addSubview:_unameLab];[_unameLab release];//用户邮箱_email = [[UITextField alloc] initWithFrame:CGRectMake(padx, 15, 200, 40)];[_email setBackgroundColor:[UIColor clearColor]];[_email setKeyboardType:UIKeyboardTypeEmailAddress];[_email setTextColor:[UIColor grayColor]];//[_email setClearButtonMode:UITextFieldViewModeWhileEditing]; //编辑时会出现个修改X[_email setTag:101];[_email setReturnKeyType:UIReturnKeyNext]; //键盘下一步Next[_email setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写[_email setAutocorrectionType:UITextAutocorrectionTypeNo];[_email becomeFirstResponder]; //默认打开键盘[_email setFont:[UIFont systemFontOfSize:17]];[_email setDelegate:self];[_email setPlaceholder:@"用户名或电子邮箱"];[_email setText:@""];[_email setHighlighted:YES];[_eview addSubview:_email];//密码UILabel *_passwdLab = [[UILabel alloc] initWithFrame:CGRectMake(20, 43, 45, 40)];[_passwdLab setText:@"密 码"];[_passwdLab setFont:lpFont];_passwdLab.highlighted = YES;_passwdLab.highlightedTextColor = [UIColor blackColor];[_passwdLab setBackgroundColor:[UIColor clearColor]];[_passwdLab setTextColor:[UIColor blackColor]];[_view addSubview:_passwdLab];[_passwdLab release];_passwd = [[UITextField alloc] initWithFrame:CGRectMake(padx, 53, 200, 40)];[_passwd setBackgroundColor:[UIColor clearColor]];[_passwd setKeyboardType:UIKeyboardTypeDefault];[_passwd setBorderStyle:UITextBorderStyleNone];[_passwd setAutocapitalizationType:UITextAutocapitalizationTypeNone]; //关闭首字母大写[_passwd setReturnKeyType:UIReturnKeyDone]; //完成[_passwd setSecureTextEntry:YES]; //验证[_passwd setDelegate:self];[_passwd setTag:102];[_passwd setTextColor:[UIColor grayColor]];[_passwd setFont:lpFont];[_passwd setText:@""[_view addSubview:_passwd]; }三、注册华贵的衣服穿在心肠污浊的人身上，显得更丑恶。
