爲什麼setText爲textView添加文本底部的textView？

Question

我在目標c的noob，我創建一個頁面xib文件，該頁面有一個textView爲空。 我在此頁面拖動UITextView並連接到自我插座。 現在我想添加像這樣的文字「我是JANATAN」。當我使用這段代碼並運行我的模擬器時，我的模擬器向我展示了我的textView，但是我看到了我的句子是textView的最後一行！ 爲什麼？這是我的形象：pic of simulator

這是我的代碼：

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 
    getTextPlaces = [self CreateTextViews]; 
    textField1 = [getTextPlaces objectAtIndex:0]; 
    [self.view addSubview:textField1]; 

    NSString *str = [_stack pop]; 
    textArray = [self readInformationFromDatabaseWithData:str]; 
    NSString *s1 = [[textArray objectAtIndex:0]objectForKey:@"Names"]; 
    textField1.text = [NSString stringWithFormat:@"%@",s1]; //this s1 value is I am janatan 
} 
- (NSMutableArray *)CreateTextViews{ 
    UITextView *tf = [[UITextView alloc] initWithFrame:CGRectMake(35, 70, 250, 50)]; 
    tf.backgroundColor = [UIColor purpleColor]; 
    tf.font = [UIFont fontWithName:@"Helvetica-Bold" size:20]; 
    tf.autocorrectionType = UITextAutocorrectionTypeNo; 
    tf.textAlignment = NSTextAlignmentRight; 
    //tf.text=@"Hello World"; 

    //second one 
    UITextView *tf1 = [[UITextView alloc] initWithFrame:CGRectMake(35, tf.frame.origin.y + 70, 250, 50)]; 
    tf1.font = [UIFont fontWithName:@"Helvetica-Bold" size:20]; 
    tf1.backgroundColor=[UIColor whiteColor]; 
    tf1.autocorrectionType = UITextAutocorrectionTypeNo; 
    tf1.textAlignment = NSTextAlignmentRight; 

    //and so on adjust your view size according to your needs 
    NSMutableArray *twoText = [[NSMutableArray alloc]init]; 

    [twoText addObject:tf]; 
    [twoText addObject:tf1]; 

    return twoText; 

}

我的朋友刪除這個你需要的是設置如下：

self.automaticallyAdjustsScrollViewInsets = NO; 

在viewDidLoad方法

。
