1.不能滚动
self.scrollEnabled = NO;2.正常字体[UIFont systemFontOfSize:30.0f]3.加粗字体[UIFont boldSystemFontOfSize:30.0f]4.文本框偏移self.textContainerInset = UIEdgeInsetsMake(TEXTVIEW_TOP_INSET, TEXTVIEW_LEFT_INSET, TEXTVIEW_BOTTOM_INSET,TEXTVIEW_RIGHT_INSET);5.获取输入状态[self becomeFirstResponder];6.是否可编辑[self setEditable:YES];
7.限制输入长度
按照这个思路，即 将要生成的文本长度 = 原始文本长度 – 选中文本长度 + 输入文本长度。再考虑到删除的情况，我的代码如下：- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{if ([text isEqualToString:@""] && range.length > 0) {//删除字符肯定是安全的return YES;}else {if (textView.text.length – range.length + text.length > MAX_INPUT_LENGTH) {UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"超出最大可输入长度" message:nil delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];[alert show];return NO;}else {return YES;}}}
8.不能选中
[self setSelectable:YES];
