-(void)textViewDidChange:(UITextView*)textView{

//博客园-FlyElephant

staticCGFloatmaxHeight =95;

CGRectframe = textView.frame;

CGSizeconstraintSize =CGSizeMake(frame.size.width,MAXFLOAT);

CGSizesize = [textViewsizeThatFits:constraintSize];

if(size.height<=maxHeight) {

size.height=maxHeight;

}

textView.scrollEnabled=NO;//不允许滚动

textView.frame=CGRectMake(frame.origin.x, frame.origin.y, frame.size.width, size.height);

}
