int值不及格，無法識別的選擇發送到實例終止應用程序由於未捕獲的異常「NSInvalidArgumentException」

我試圖通過不同的文件，但在標題中提到得到一個錯誤之間兩個整數值。int值不及格，無法識別的選擇發送到實例終止應用程序由於未捕獲的異常「NSInvalidArgumentException」

錯誤在這行： - （的NSString *）查詢：（的NSString *）中得到：（INT）dictio中GET1：（INT）dictio1;

int main(int argc, char * argv[]) 
{ 
    @autoreleasepool { 
     return UIApplicationMain(argc, argv, nil, NSStringFromClass([MaisOuiAppDelegate class])); 
    } 
}

從文件傳遞：

int d=0; 
int d1=0;

文件傳遞到：

@interface MaisOuiDictionary : NSObject 

- (NSString *) lookup: (NSString *) in; 
- (int) dic : (int) dictio; 
- (int) dic1 : (int) dictio1; 


@end 



- (NSString *) lookup: (NSString *)in get:(int)dictio  get1:(int)dictio1; 
{ 


    // if(dictio==10 && dictio1==10) 
    { 
    NSString *rv = [self.wordsE_S objectForKey: in]; 
    if (!rv) 
     return @"*** no translation ***"; 

    return rv; 
    } 
// return @"**nothing**"; 
}

有人可以告訴我我的錯在哪裏。我試圖將所有值更改爲int *和NSInteger *，但仍然得到相同的錯誤。

你能在你的問題中添加完整的錯誤？ – Volker

這沒有任何意義。首先，發佈確切完整的錯誤消息。其次 - 哪一行代碼導致了問題？ – rmaddy

已修改，請現在查看。 – rbk

你已經實現了這個方法

- (NSString*)lookup:(NSString*)in get:(int)dictio get1:(int)diction;

...但它看起來像你試圖調用此方法（即已經在你的接口中定義）

- (NSString*)lookup:(NSString*)in;

因爲lookup:的實現不存在，你會得到一個異常拋出。您需要：

聲明lookup:get:get1:在你的界面，並呼籲在textFieldShouldReturn:而不是lookup:
實現lookup:在您的實現

這一切都歸結到你叫那並不是一個方法不存在。對目標C方法命名澄清可以在這裏找到：Method Syntax in Objective C
