如何获得indexPath.row in didFinishLoading目标C

Question

我是iOS新手，我面临的问题是如何获取IndexPath.row以外的cellforrowAtIndexPath方法，即didFinishLoading。我的代码是这样的

- (void)connectionDidFinishLoading:(NSURLConnection *)connection{ 
    loginStatus = [[NSString alloc] initWithBytes: [myNSMDataFromServer mutableBytes] length:[myNSMDataFromServer length] encoding:NSUTF8StringEncoding]; 
    NSLog(@"loginStatus =%@",loginStatus); 
    NSError *parseError = nil; 
    NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:loginStatus error:&parseError]; 
    NSLog(@"JSON DICTIONARY = %@",xmlDictionary); 
    recordResult = [xmlDictionary[@"success"] integerValue]; 
    NSLog(@"Success: %ld",(long)recordResult); 
    NSDictionary* Address=[xmlDictionary objectForKey:@"soap:Envelope"]; 
    NSLog(@"Address Dict = %@",Address); 
    NSDictionary *new =[Address objectForKey:@"soap:Body"]; 
    NSLog(@"NEW DICT =%@",new); 
    NSDictionary *LoginResponse=[new objectForKey:@"TFMComplaints_GetNewResponse"]; 
    NSLog(@"Login Response DICT =%@",LoginResponse); 
    NSDictionary *LoginResult=[LoginResponse objectForKey:@"TFMComplaints_GetNewResult"]; 
    NSLog(@"Login Result =%@",LoginResult); 
    if(LoginResult.count>0) 
    { 
     NSLog(@"Login Result = %@",LoginResult); 
     NSLog(@"Login Result Dict =%@",LoginResult); 
     NSString *teststr =[[NSString alloc] init]; 
     teststr =[LoginResult objectForKey:@"text"]; 
     NSLog(@"Test String Value =%@",teststr); 
     NSString *string = [LoginResult valueForKey:@"text"]; 
     NSLog(@"Now String is =%@",string); 
     NSData *data =[string dataUsingEncoding:NSUTF8StringEncoding]; 
     NSError* error; 
     NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:NSUTF8StringEncoding error:&error]; 
     NSIndexPath *selectedIndexPath = [closetbl indexPathForSelectedRow]; 
     NSDictionary *firstObj = [array objectAtIndex:selectedIndexPath.row]; 

     idarray=[[NSMutableArray alloc]init]; 

     idarray=[firstObj valueForKey:@"Key"]; 
     NSLog(@"Result Array =%@",idarray); 
} 

我得到只有一个值，该值在0提前

谢谢！

只需添加一个for循环数组：

for (int i = 0; i < array.count; i++) 
{ 
    //where i will be the index path. You can use it like this 
    NSDictionary *firstObj = [array objectAtIndex:i]; 

} 

在你的情况，你可以使用它像这样：

idarray=[[NSMutableArray alloc]init]; 

for (int i = 0; i < array.count; i++){ 
    NSDictionary *firstObj = [array objectAtIndex:i]; 
    [idarray addObject:[firstObj valueForKey:@"Key"]]; 
    NSLog(@"Result Array =%@",idarray); 

    } 

Answer 2

NSIndexPath *selectedIndexPath = [tableView indexPathForSelectedRow];

希望这有助于。

您可以使用下面的代码来获取索引路径，并从此索引路径中获取所选单元格。

let indexPath = self.tblObj.indexPathForSelectedRow! 

let currentCell = self.tblObj.cellForRowAtIndexPath(indexPath)! as! YourTableViewCell
