iOS-WACloudAccessControlClient可能不响应setToken？ [英] ios - WACloudAccessControlClient may not respond to setToken?

问题描述

我正在尝试获取令牌，但收到类似'WACloudAccessControlClient的警告消息，可能无法响应setToken

I'm trying to get token,but getting warning message like 'WACloudAccessControlClient, may not respond to setToken

 - (BOOL)webView:(UIWebView *)webView
shouldStartLoadWithRequest:(NSURLRequest *)request
 navigationType:(UIWebViewNavigationType)navigationType
{

    NSURL *url = [[NSURL alloc] initWithString:@"URL"];

if(url)

{

 /* make the call re-entrant when we re-load the content ourselves */

    if([url isEqual:[request URL]])
    {
        return YES;
    }

    [url release];
}

url = [[request URL] retain];
NSString* scheme = [url scheme];

if([scheme isEqualToString:@"acs"])
{
    // parse the JSON URL parameter into a dictionary
    NSDictionary* pairs = [self parsePairs:[url absoluteString]];
    if(pairs)
    {
        WACloudAccessToken* accessToken;
        accessToken = [[WACloudAccessToken alloc] initWithDictionary:pairs];
        [WACloudAccessControlClient setToken:accessToken];

        [self dismissModalViewControllerAnimated:YES];
    }

    return NO;
}

[NSURLConnection connectionWithRequest:request delegate:self];

return NO;

}

有什么想法吗？

推荐答案

似乎WACloudAccessControlClient是一个类，而不是您编写的代码中的实例变量。

Seems like WACloudAccessControlClient is a class, not an instance variable in the code you wrote.

在调用类似[AClass someMethod]之类的东西时，实际上是在使用AClass的结构，而不是实例。
结构无法将任何运行时数据保存/存储在内存中，因为它没有分配内存。

When you are calling something like [AClass someMethod], you are actually working with structure of AClass, not with an instance. Structure cannot save/store in memory any runtime data, because it doesn't have allocated memory.

如果WACloudAccessControlClient是此代码中的实例变量，则它不是用语句导入的：

If WACloudAccessControlClient is an instance variable in this code, then it's not imported with statement:

#import "WACloudAccessControlClient.h"

...或类似的东西。编译器无法检测到使用该签名声明的任何方法。
有关类方法的更多信息，请阅读此。

... or something similar to this. Compiler cannot detect any method declared with such signature. For more information about class methods read this.
