iOS开发~UITextView光标不在起始位置问题

问题：当用UITextView展示超出屏幕的文本内容时，并且禁止了其编辑功能，发现打开页面后，光标不在开头位置，而是在屏幕中间

解决办法：

- (void) viewDidAppear:(BOOL)animated {    [super viewDidAppear:animated];        self.contentTextView.editable = NO;}- (void)viewDidLoad {    [super viewDidLoad];    self.contentTextView.attributedText = attributedString;    self.contentTextView.editable = YES;    [self.contentTextView becomeFirstResponder];    self.contentTextView.selectedRange = NSMakeRange(0,0);    self.contentTextView.tintColor = [UIColor clearColor];}
