'NSURLRequest'沒有可見的@interface聲明選擇器'initwithURL：'

Question

Xcode的新手，我的代碼在這裏出了什麼問題？

[super viewDidLoad]; 
// Do any additional setup after loading the view, typically from a nib. 
Webview.userInteractionEnabled = TRUE; 
[UIWebView loadRequest: [[[NSURLRequest alloc] initwithURL:[[NSURL alloc] initWithString:@"http://www.reddit.com/r/Diecast/"]]]; 
[super viewDidLoad]; 

請幫忙，如果我做錯了什麼，請糾正我！我正在嘗試爲該特定頁面創建瀏覽器，以便人們可以打開圖片並瀏覽頁面。

謝謝！

Answer 1

檢查你的資本上-initWithURL:

此外，您還需要調用loadRequest:您的網頁視圖實例，而不是通過類UIWebView：

NSURL *url = [[NSURL alloc] initWithString:@"http://www.reddit.com/r/Diecast/"]; 
NSURLRequest *request = [NSURLRequest alloc] initWithURL:url]; 
[Webview loadRequest:request]; 

Answer 2

試試這個

[super viewDidLoad]; 
// Do any additional setup after loading the view, typically from a nib. 
Webview.userInteractionEnabled = YES; 
[Webview loadRequest: [[[NSURLRequest alloc] initWithURL:[[NSURL alloc] initWithString:@"http://www.reddit.com/r/Diecast/"]]];
