基本上我需要知道 webview 如何知道正在点击哪种文件扩展名（png、zip 等），然后推送另一个视图控制器。
我之前尝试过没有文件扩展名代码，它会推送另一个视图就好了。
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *theRessourcesURL = [request URL];
DetailViewController *vc = [[DetailViewController alloc] init];
[vc downloadURL:theRessourcesURL userInfo:nil];
[self.navigationController pushViewController:vc animated:YES];
dlvc.delegate = self;
}
return YES;
}
非工作代码：
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *theRessourcesURL = [request URL];
NSString *fileExtension = [theRessourcesURL pathExtension];
if ([fileExtension isEqualToString:@"png"]) {
MYViewController *vc = [[MYViewController alloc] init];
[dlvc downloadURL:theRessourcesURL userInfo:nil];
[self.navigationController pushViewController:vc animated:YES];
vc.delegate = self;
}
else{}
}
return YES;
}
大部分时间都在工作。
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if(navigationType == UIWebViewNavigationTypeLinkClicked) {
NSURL *theRessourcesURL = [request URL];
NSString *fileExtension = [theRessourcesURL pathExtension];
NSLog(@"fileExtension is: %@", fileExtension);
if ([fileExtension isEqualToString:@"php"] || [fileExtension isEqualToString:@".png"] || [fileExtension isEqualToString:@".zip"] || [fileExtension isEqualToString:@".deb"] || [fileExtension isEqualToString:@".jpg"] || [fileExtension isEqualToString:@".mp3"]) {
NSError *error = nil; //error setting
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"Downloads"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
HCDownloadViewController *dlvc = [[HCDownloadViewController alloc] init];
[dlvc downloadURL:theRessourcesURL userInfo:nil];
[self.navigationController pushViewController:dlvc animated:YES];
dlvc.delegate = self;
return NO;
}
else{}
}
return YES;
}
我也尝试将其用作入门基础但没有成功，因为我不使用界面构建器，所以我不知道是否可以使用 IBActions（如果可以的话，我不知道如何正确实现它们）。如何从 UIWebView 下载文件并再次打开
任何帮助，将不胜感激。
