iOS--导航栏样式
push返回按钮样式:
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem.backBarButtonItem = item; self.navigationController.navigationBar.tintColor = [UIColor grayColor]; [self.navigationItem setHidesBackButton:YES];
自由点击事件:
//用户协议跳转 UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelClick)]; // 2. 将点击事件添加到label上 [self.UserRate addGestureRecognizer:labelTapGestureRecognizer]; self.UserRate.userInteractionEnabled = YES; // 可以理解为设置label可被点击
创建左右导航栏按钮,搜索与个人中心:
//创建左右导航栏按钮,搜索与个人中心 self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[self scaleToSize:[UIImage imageNamed:@"sousuo.png"] size:CGSizeMake(20, 19.6)] style:UIBarButtonItemStylePlain target:self action:@selector(Actionleft:)]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[self scaleToSize:[UIImage imageNamed:@"persons.png"] size:CGSizeMake(20, 20)] style:UIBarButtonItemStylePlain target:self action:@selector(Actionright:)]; //导航栏个人信息按钮 -(void)Actionright:(id)send{ NSLog(@"跳转到个人中心页面"); PersonalViewController *PersonalView = [self.storyboard instantiateViewControllerWithIdentifier:@"PersonalView"]; [self.navigationController pushViewController:PersonalView animated:PersonalView]; } //导航栏搜索按钮点击事件 -(void)Actionleft:(id)send{ NSLog(@"跳转到搜索页面"); SearchViewController *search = [self.storyboard instantiateViewControllerWithIdentifier:@"search"]; [self.navigationController pushViewController:search animated:search]; } //设置图片大小 - (UIImage *)scaleToSize:(UIImage *)img size:(CGSize)size{ // 创建一个bitmap的context // 并把它设置成为当前正在使用的context UIGraphicsBeginImageContext(size); // 绘制改变大小的图片 [img drawInRect:CGRectMake(0, 0, size.width, size.height)]; // 从当前context中创建一个改变大小后的图片 UIImage* scaledImage = UIGraphicsGetImageFromCurrentImageContext(); // 使当前的context出堆栈 UIGraphicsEndImageContext(); // 返回新的改变大小后的图片 return scaledImage; }
