将字符串更改为整数iphone

Question

在此代码中，我想更改字符串创建为整数，并希望将其用于进一步处理。我怎样才能做到这一点？ 这里的recordId isEqualToString：@“1”，我想改变这个字符串“1”为整数，然后想用它

-(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

您不必这样做。只需使用NSString'sintValue消息。

您的代码将是这样的：

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]; 

试试这一个。
