5.在navigationItem中添加多个右按钮 定义一组button，将buttons放入array，再令rightBarButtonItems(注意有s) = array。 UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:nil]; UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:nil]; UIBarButtonItem *button3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:nil]; UIBarButtonItem *button4 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:nil]; NSArray *array = [[NSArray alloc] initWithObjects:button1,button2,button3,button4, nil]; self.navigationItem.rightBarButtonItems = array; 6.设置NavigationBar背景颜色 self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:218/255 green:222/255 blue:250/255 alpha:1]; 7.设置NavigationBar背景图片 UIImage *title_bg = [UIImage imageNamed:@"title_bg"]; //获取图片 CGSize titleSize = self.navigationController.navigationBar.bounds.size; //获取NavigationBar的位置和大小 title_bg = [self scaleToSize: title_bg size:titleSize]; //设置图片大小与NavigationBar相同 [self.navigationController.navigationBar setBackgroundImage:title_bg forBarMetrics:UIBarMetricsDefault]; //设置背景 //用于调整图片大小的方法 -(UIImage *) scaleToSize: (UIImage *) img size:(CGSize) size{ UIGraphicsBeginImageContext(size); [img drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *scaledImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return scaledImage; } 5.在navigationItem中添加多个右按钮 定义一组button，将buttons放入array，再令rightBarButtonItems(注意有s) = array。 UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:nil]; UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:nil]; UIBarButtonItem *button3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:nil]; UIBarButtonItem *button4 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:nil]; NSArray *array = [[NSArray alloc] initWithObjects:button1,button2,button3,button4, nil]; self.navigationItem.rightBarButtonItems = array; 6.设置NavigationBar背景颜色 self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:218/255 green:222/255 blue:250/255 alpha:1]; 7.设置NavigationBar背景图片 UIImage *title_bg = [UIImage imageNamed:@"title_bg"]; //获取图片 CGSize titleSize = self.navigationController.navigationBar.bounds.size; //获取NavigationBar的位置和大小 title_bg = [self scaleToSize: title_bg size:titleSize]; //设置图片大小与NavigationBar相同 [self.navigationController.navigationBar setBackgroundImage:title_bg forBarMetrics:UIBarMetricsDefault]; //设置背景 //用于调整图片大小的方法 -(UIImage *) scaleToSize: (UIImage *) img size:(CGSize) size{ UIGraphicsBeginImageContext(size); [img drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *scaledImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return scaledImage; }
