_content_textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 25, 300, 80)];
_content_textView.font = [UIFont boldSystemFontOfSize:13];
_content_textView.delegate = self;
//设置键盘，使换行变为完成字样

_content_textView.returnKeyType = UIReturnKeyDone;

_placeholder_label = [[UILabel alloc] initWithFrame:CGRectMake(12, 25, 300, 30)];
