Question

我是客观C编程的新手。

我创建了一个PygLatin应用程序，但它一直在崩溃。如果您发现我的代码存在任何问题，请告诉我。

由于未捕获的异常终止应用＆＃39; NSRangeException＆＃39;，原因：＆＃39; - [__ NSArrayM objectAtIndex：]：index 5超越界限[0 .. 4]＆＃39; 首先抛出调用堆栈：

非常感谢我能得到的所有帮助！：）

@implementation RootViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.userInputTextField.delegate = self;

}

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];//resigns the keyboard every time return button is pressed
    return YES;
}

- (IBAction)pygButton:(id)sender
{
    self.inputText = [self.userInputTextField.text lowercaseString];//user input  is lowercase
    NSArray *wordsArray = [self.inputText componentsSeparatedByString: @" "];    //separate words into arrays.
    [self charsplitter: wordsArray];
}

放
self.subsequentCharCount++;
在while循环结束时表示在下面 [self print: completedWord];
