Question

我正在尝试在单个UIWebView上展示多个UIViewController，每个{1}}都应显示一个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;

并在我的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];

}

现在问题是第一个UIWebview正在显示HTML内容，但接下来的所有内容都会收到错误消息

“重新定义'路径'”
“重新定义'url'”
“重新定义'请求'”

我还可以清楚地看到我定义了相同的东西4次，但删除这些定义将完全破坏代码。我对xcode的体验非常低，所以我实际上并不知道如何解决它。请深入了解显示多个UIWebview的正确解决方案。

@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];

    }

如何在具有本地文件的单个UIViewController上显示多个UIWebView？
