不是您常用的'Class'可能不會響應'method'警告 - iPhone/Objective-C

我知道您必須已經看到此警告並且經常給出解決方案，但我的情況有點特別。
我只收到一個類的警告，但是正確設置了一切（導入，實現，頭文件等）。我在XCode編寫Objective-C已經有一段時間了，並且會爲我自己說，我已經贏得了iPhone編程的豐富經驗。我完全相信，一切都很好。
看來，XCode莫名其妙地沒有認識到我對班級所做的改變。它甚至提出了一些不屬於這個類的方法。我在另一臺Mac上檢查了這個項目並在那裏建立了它，並且一切都很好，完全沒有任何警告。
我不想重新安裝XCode來擺脫這些不應該存在的煩人警告。有關如何告訴XCode必須購買眼鏡的建議？幫助非常感謝=）不是您常用的'Class'可能不會響應'method'警告 - iPhone/Objective-C

編輯：好的，就這樣，沒有人可以說，我是瘋了還是什麼，這裏是代碼，並在年底小的解釋：

#import <Foundation/Foundation.h> 


@interface URLConnection : NSObject { 
NSString *theURL; 
NSMutableData *receivedData; 
id delegate; // delegate needed for handling response 
} 

@property (nonatomic, retain) NSMutableData *receivedData; 
@property (retain) id delegate; 

- (NSData*) sendSynchronousRequest:(NSData*)_postData; 
- (void) sendRequest:(NSData*)_postData; 

- (void)setDelegate:(id)val; 
- (id)delegate; 

@end 

#import "URLConnection.h" 


@implementation URLConnection 

@synthesize receivedData, delegate; 


- (id) init 
{ 
if (self = [super init]) { 
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
    if (![[defaults stringForKey:@"bankurl"] isEqualToString:@"<Custom URL>"]) { 
     theURL = [[defaults stringForKey:@"bankurl"] retain]; 
    } else { 
     theURL = [[defaults stringForKey:@"bankurl_list"] retain]; 
    } 
    receivedData = [[NSMutableData alloc] init]; 
} 
return self; 
} 

- (void)setDelegate:(id)val 
{ 
    delegate = val; 
} 

- (id)delegate 
{ 
return delegate; 
} 


/* send a synchronous request (specified for xml documents) */ 
- (NSData*) sendSynchronousRequest:(NSData*)_postData 
{ 
NSString *_urlString = theURL; 
NSMutableURLRequest *_urlRequest = [[NSMutableURLRequest alloc] init]; 
[_urlRequest setURL:[NSURL URLWithString:_urlString]]; 
[_urlRequest setHTTPMethod:@"POST"]; 
[_urlRequest setValue:@"text/xml" 
    forHTTPHeaderField:@"Content-Type"]; 
[_urlRequest setHTTPBody:_postData]; 

// response 
NSHTTPURLResponse *_urlResponse = nil; 
NSError *_error = [[NSError alloc] init]; 
NSData *_responseData = [NSURLConnection sendSynchronousRequest:_urlRequest 
               returningResponse:&_urlResponse 
                  error:&_error]; 
[_urlRequest release]; 
NSString *_result = [[NSString alloc] initWithData:_responseData 
              encoding:NSUTF8StringEncoding]; 
NSLog(@"Response code: %d", [_urlResponse statusCode]); 
if ([_urlResponse statusCode] >= 200 && [_urlResponse statusCode] < 300) { 
    NSLog(@"Response: %@", _result); 
} 
return _responseData; 
} 


/* send an asynchronous request (specified for xml documents) */ 
- (void) sendRequest:(NSData*)_postData 
{ 
NSMutableURLRequest *_urlRequest = [[NSMutableURLRequest alloc] init]; 
[_urlRequest setURL:[NSURL URLWithString:theURL]]; 
[_urlRequest setHTTPMethod:@"POST"]; 
[_urlRequest setValue:@"text/xml" 
    forHTTPHeaderField:@"Content-Type"]; 
[_urlRequest setHTTPBody:_postData]; 

[[NSURLConnection alloc] initWithRequest:_urlRequest delegate:self]; 
[_urlRequest release]; 
} 


/* 
    * NSURLRequest Delegate 
    * if a response comes back, clear receivedData to make room for the response data 
    */ 
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 
{ 
[receivedData setLength:0]; 
} 


/* 
* NSURLRequest Delegate 
* if data is received, append the chunk of data to receivedData 
*/ 
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data 
{ 
[receivedData appendData:data]; 
} 


/* 
* NSURLRequest Delegate 
* when all response data has been stored, call didFinishDownload() in the class 
* which set itself as the delegate 
*/ 
- (void)connectionDidFinishLoading:(NSURLConnection *)connection 

{ 
[delegate didFinishDownload:receivedData]; 

[connection release]; 
//[receivedData release]; 
} 



- (void) dealloc 
{ 
[theURL release]; 
theURL = nil; 
[super dealloc]; 
} 

@end

第一所有，是的，我知道該行「[代理didFinishDownload：receivedData];」會發出警告，但這不是我寫的問題。當我按Alt + Esc查看方法建議時，以上所有內容都在列表中，而且還包括「sendRequest：theURL：」和「sendMail：」，這些內容很久以前就被移除了。

我不知道爲什麼，但今天啓動XCode後警告已被刪除。打我...問題解決了，我認爲... – zhar 2010-11-30 12:54:12
