內存泄漏錯誤

Question

我對iPhone應用程序開發非常新，並且無法在我的代碼上運行泄漏分析器（XCode-> Product-> Analyze）時糾正此錯誤。它顯示了某些線路上物體的潛在泄漏。

1）方法返回與1的物鏡C的對象保留計數（由於參考）

2）對象上的線128分配未在此執行路徑以後引用和具有保留的1計數（對象泄露）.responeData保留在財產申報部分

-(IBAction)registerButtonPressed:(id)sender 
{ 

self.responseData = [NSMutableData data]; 

NSString *username = txtUsername.text; 

NSString *jsonstring = [NSString stringWithFormat:@"http://demo.elgghub.com/apis/services/api/rest/json/?method=register&username=%@",username]; 


NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:jsonstring]]; 
[[NSURLConnection alloc] initWithRequest:request delegate:self]; 
} 


- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 

[responseData setLength:0]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 

[responseData appendData:data]; 
} 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { 

[connection release]; 

self.responseData = nil; 

UIAlertView *alert = [[UIAlertView alloc] 
         initWithTitle:@"Error" 
         message:@"Please check your network connection and relaunch the application" 
         delegate:self 
         cancelButtonTitle:@"Dismiss" 
         otherButtonTitles:nil, nil]; 

[alert show]; 

[alert release]; 

} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{ 

[connection release]; 

NSString *responseStringReg = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
self.responseData = nil; 


NSDictionary *login =(NSDictionary*)[responseStringReg JSONValue] ; 
[responseStringReg release]; 
NSNumber *status = [login objectForKey:@"status"]; 
NSString *statusString = [status stringValue]; 
NSString *message = [login objectForKey:@"message"]; 

} 

-(void)dealloc 
{ 

[responseData release]; 

[demoView release]; 

[super dealloc]; 
}

如果線128是您創建NSURLConnection的出現的警告，因爲分析器無法知道它會在委託被釋放的方式。無論如何，你可能應該存儲對它的引用，也許在一個實例變量中。
