ios - 如何使用本地文件在单个 UIViewController 上显示多个 UIWebView？

Question

我试图在单个 UIViewController 上显示多个 UIWebView，每个应该显示一个 HTML 文件。

在我的 camView.h 文件中，我有以下代码:

@interface camView : UIViewController
@property (weak, nonatomic) IBOutlet UIWebView *cam01_valk01;
@property (weak, nonatomic) IBOutlet UIWebView *cam02_valk02;
@property (weak, nonatomic) IBOutlet UIWebView *cam03_valk03;
@property (weak, nonatomic) IBOutlet UIWebView *cam04_tunnel;

在我的 camView.m 文件中:

@interface camView ()

@end

@implementation camView

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    NSString *path = [[NSBundle mainBundle] pathForResource:@"cam1_valk01" ofType:@"html"];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [_cam01_valk01 loadRequest:request];

    NSString [[[NSBundle mainBundle] pathForResource:@"cam2_valk02" ofType:@"html"];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [_cam02_valk02 loadRequest:request];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"cam3_valk03" ofType:@"html"];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [_cam03_valk03 loadRequest:request];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"cam4_tunnel" ofType:@"html"];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [_cam04_tunnel loadRequest:request];

}

现在的问题是第一个 UIWebview 正在显示 HTML 内容，但所有接下来的都收到错误消息

1. “重新定义‘路径’”
2. “重新定义‘url’”
3. “重新定义‘请求’”

我还可以清楚地看到我定义了 4 次相同的东西，但是删除这些定义将完全破坏代码。我对 xcode 的经验很低，所以我实际上不知道如何解决它。请详细写下显示多个 UIWebview 的正确解决方案是什么。

@interface camView ()

@end

@implementation camView

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view. 
   NSString *path = [[NSBundle mainBundle] pathForResource:@"cam1_valk01" ofType:@"html"];
        NSURL *url = [NSURL fileURLWithPath:path];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        [_cam01_valk01 loadRequest:request];

        NSString * pathSec = [[NSBundle mainBundle] pathForResource:@"cam2_valk02" ofType:@"html"];
        NSURL *urlSecond = [NSURL fileURLWithPath:pathSec];
        NSURLRequest *requestSecond = [NSURLRequest urlSecond];
        [_cam02_valk02 loadRequest:requestSecond];

        NSString *pathThird = [[NSBundle mainBundle] pathForResource:@"cam3_valk03" ofType:@"html"];
        NSURL *urlThird = [NSURL fileURLWithPath:pathThird];
        NSURLRequest *requestThird = [NSURLRequest requestWithURL:urlThird];
        [_cam03_valk03 loadRequest:requestThird];

        NSString *pathFour = [[NSBundle mainBundle] pathForResource:@"cam4_tunnel" ofType:@"html"];
        NSURL *urlFour = [NSURL fileURLWithPath:pathFour];
        NSURLRequest *requestFour = [NSURLRequest requestWithURL:urlFour];
        [_cam04_tunnel loadRequest:requestFour];

    }
