我在滚动视图上使用 UITextView ...我希望它在我写东西时自动扩展......但我无法做到......
textViewBusiness = [[UITextView alloc] initWithFrame:CGRectMake(25,332,268,60)];
textViewBusiness.text=strMyBusiness;
textViewBusiness.editable=NO;
textViewBusiness.font = [UIFont fontWithName:@"Arial" size: 17.0];
textViewBusiness.layer.borderWidth = 2.0f;
textViewBusiness.layer.borderColor = [[UIColor grayColor] CGColor];
textViewBusiness.backgroundColor = [UIColor clearColor];
[textViewBusiness setTextColor:[UIColor blackColor]];
[self.scrollView addSubview: textViewBusiness];
CGRect frame = textViewBusiness.frame;
frame.size.height = textViewBusiness.contentSize.height;
textViewBusiness.frame = frame;
这段代码对我不起作用...
谢谢
