由於未捕獲的異常'NSRangeException'xcode 5

終止應用程序我在一個選擇器視圖函數中得到了這個錯誤，它將數據從google電子表格中的文本文件..這是該函數的代碼。由於未捕獲的異常'NSRangeException'xcode 5

{ 
- (IBAction)clickText:(id)sender 

int tag = [(UITextField*)sender tag]; 
if (tag!=11) 
    if (tag!=12) 
     if (tag!=13) 
      if (tag!=14) 
       if (tag!=15) 
        if (tag!=16) 
         if (tag!=17) 
          if (tag!=18) 
           if (tag!=19) 


             { 
              [sender resignFirstResponder]; 
             } 
self.myPicker.hidden = NO; 
selectedTable = tag; 
[sender resignFirstResponder]; 
float yy = 10; 
switch (tag) { 
    case 11: yy = self.txtTgfeet.frame.origin.y + self.myPicker.frame.size.height; 
     break; 
    case 12: yy = self.txtTginches.frame.origin.y + self.myPicker.frame.size.height; 
     break; 
    case 13: yy = self.txtTgfraction.frame.origin.y + self.myPicker.frame.size.height; 
     break; 
    case 14: yy = self.txtBgfeet.frame.origin.y - self.myPicker.frame.size.height; 
     break; 
    case 15: yy = self.txtBginches.frame.origin.y - self.myPicker.frame.size.height; 
     break; 
    case 16: yy = self.txtBgfraction.frame.origin.y - self.myPicker.frame.size.height; 
     break; 
    case 17: yy = self.txtGravity.frame.origin.y - self.myPicker.frame.size.height; 
     break; 
    case 18: yy = self.txtBsw.frame.origin.y - self.myPicker.frame.size.height; 
     break; 
    case 19: yy = self.txtTemp.frame.origin.y - self.myPicker.frame.size.height; 
     break; 


    default: 
     break; 
} 

[self.myPicker setFrame:CGRectMake(self.txtTgfeet.frame.origin.x, yy, self.txtTgfeet.frame.size.width, 216)]; 

[self.ar removeAllObjects]; 

NSString *theURL = @"https://docs.google.com/spreadsheet/pub?key=0AobIgii9hBGPdDJ3TmgxSkRzVFBKWXVnTWdQcGtyMFE&single=true&gid=9&output=txt"; 
NSString *theFile = [NSString stringWithContentsOfURL:[NSURL URLWithString:theURL] encoding:NSUTF8StringEncoding error:nil]; 
NSLog(@"%@",theFile); 
NSArray *theCells = [theFile componentsSeparatedByString:@"\n"]; 



for (int i=1; i < [theCells count]; i++) 
{ 
    //  if (i > 0) 
    { 
     NSArray *value =[[theCells objectAtIndex:i] componentsSeparatedByString:@"\t"]; 
     [self.ar addObject:[value objectAtIndex:tag+1]]; 

    } 
} 
[self.myPicker selectRow:0 inComponent:0 animated:NO]; 
[self.myPicker reloadAllComponents];

此功能在其他應用程序完美的工作，我只爲我要這個功能另一個應用程序使這個。現在，當我點擊文本字段，我得到這個錯誤：

什麼似乎是這裏的問題？

爲什麼使用標籤來識別觀點的一個很好的例子是非常脆。對象引用在可用時更好。一個'if'語句將代碼推到最右邊，一個大的'switch'語句是代碼味道。 – Abizern

if（！（tag> = 11）&&！（tag <= 19）） –

是的，我已經修好了，謝謝！ – user2818570

在這裏可以清楚地提到，[__NSArrayM objectAtIndex：]：索引12超出範圍[0 .. 8]」

您正在嘗試訪問第12 [指數12和陣列具有0-8對象只]元素這是不存在的，所以應用程序崩潰。

使用以下行斷點檢查，

[self.ar addObject:[value objectAtIndex:tag+1]];

你的問題似乎是在這裏：

[value objectAtIndex:tag+1]

您正在訪問的指數12，當你的陣列value只包含9個元素。

NSArray *value =[[theCells objectAtIndex:i] componentsSeparatedByString:@"\t"]; 
if ([value count]>tag+1) { 
    [self.ar addObject:[value objectAtIndex:tag+1]]; 
    }
