將字符串更改爲整數iphone

Question

在此代碼中，我想更改字符串創建爲整數，並希望將其用於進一步處理。我怎樣才能做到這一點？ 這裏的recordId isEqualToString：@「1」，我想改變這個字符串「1」爲整數，然後想用它

-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
    namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ 

    if (foundRecordId) { 
     NSLog(@"didEndElement: %@", recordId);  
    } 

    if ([recordId isEqualToString:@"1"]) { 

     NSLog(@"Only 1 account"); 

     MainScreenController *mainScreen1 = [[MainScreenController alloc] initWithNibName:@"MainScreen" bundle:nil ]; 

     self.mainScreen = mainScreen1; 

     [self.view addSubview: mainScreen1.view];   
    } 

    else if ([recordId isEqualToString:@"0"]){ 

     NSLog(@"Accounts more than 1"); 

     ChooseAccountsController *chooseAccount = [[ChooseAccountsController alloc] initWithNibName:@"ChooseAccountsController" bundle:nil]; 
     self.chooseAcc = chooseAccount; 
     [self.view addSubview:chooseAccount.view];  
    } 

} 

Answer 1

您不必這樣做。只需使用NSString'sintValue消息。

您的代碼將是這樣的：

if ([recordId intValue] == 1]) { 
    // do what you need when 1 
} else if ([recordId intValue] == 0) { 
    // do what you need when 0 
} 

Answer 2

[recordId intValue]; 

試試這一個。
