UiTextView - position when only one line is added

When 2 or more lines are added to my UiTextView it looks good but when the user enters just one line the text stays in the middle of the UiTextView. How can I force it to stay on the top left side of the UiTextView ?

I just found a much simpler solution. The next code will move just the text: [textView setContentInset:UIEdgeInsetsMake(5, 0, 5,0)]

You can check this blog (iOS: Vertical aligning text in a UITextView) which explains how to do center and bottom vertical alignment. Use similar logic and set contentOffset y param as zero in your case to make it top aligned.

This is the code from the blog,

- (void) viewDidLoad {
   [textField addObserver:self forKeyPath:@"contentSize" options:(NSKeyValueObservingOptionNew) context:NULL];
   [super viewDidLoad];
}

-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
   UITextView *tv = object;
   //Center vertical alignment
   //CGFloat topCorrect = ([tv bounds].size.height - [tv contentSize].height * [tv zoomScale])/2.0;
   //topCorrect = ( topCorrect < 0.0 ? 0.0 : topCorrect );
   //tv.contentOffset = (CGPoint){.x = 0, .y = -topCorrect};

   //Bottom vertical alignment
   CGFloat topCorrect = ([tv bounds].size.height - [tv contentSize].height);
    topCorrect = (topCorrect <0.0 ? 0.0 : topCorrect);
    tv.contentOffset = (CGPoint){.x = 0, .y = -topCorrect};
}
