A scrollView felül egy UIImageView-t tartalmaz, az UITextView-t pedig scrollingEnabled = NO , szeretném görgetni a scrollView-t azon a helyen, ahol gépelek.
- (void)createScrollView{
//TPKeyboardAvoidingScrollView *scrollView = [[TPKeyboardAvoidingScrollView alloc]init];
UIScrollView *scrollView = [[UIScrollView alloc]init];
//[self.view insertSubview:scrollView belowSubview:_mediaSelectionView];
[self.view addSubview: scrollView];
[scrollView setTranslatesAutoresizingMaskIntoConstraints: NO];
self.scrollView = scrollView;
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.bouncesZoom = NO;
scrollView.alwaysBounceVertical = YES;
scrollView.clipsToBounds = YES;
self.automaticallyAdjustsScrollViewInsets = YES;
NSLayoutConstraint *scrollViewTop = [NSLayoutConstraint
constraintWithItem: scrollView
attribute: NSLayoutAttributeTop
relatedBy: NSLayoutRelationEqual
toItem: self.navigationBarBGView
attribute: NSLayoutAttributeBottom
multiplier: 1 constant:0.0
];
NSLayoutConstraint *scrollViewLeading = [NSLayoutConstraint
constraintWithItem: scrollView
attribute: NSLayoutAttributeLeading
relatedBy: NSLayoutRelationEqual
toItem: self.view
attribute: NSLayoutAttributeLeading
multiplier: 1 constant:0.0
];
NSLayoutConstraint *superViewTraling = [NSLayoutConstraint
constraintWithItem: self.view
attribute: NSLayoutAttributeTrailing
relatedBy: NSLayoutRelationEqual
toItem: scrollView
attribute: NSLayoutAttributeTrailing
multiplier: 1 constant:0.0
];
NSLayoutConstraint *bottomLayoutGuideTop = [NSLayoutConstraint
constraintWithItem:self.view
attribute: NSLayoutAttributeBottom
relatedBy: NSLayoutRelationEqual
toItem: scrollView
attribute: NSLayoutAttributeBottom
multiplier: 1 constant:0.0
];
//Add All Constrains.
[self.view addConstraints: @[scrollViewTop , scrollViewLeading , superViewTraling , bottomLayoutGuideTop ]];
_contentView = [[UIView alloc]init];
[scrollView addSubview: _contentView];
[_contentView setConstraintFlag];
[_contentView setFullWidth];
[_contentView setTopFromParent:0];
}
- (void)createCommentTextView{
UITextView *textView = [[UITextView alloc]init];
textView.backgroundColor = [UIColor clearColor];
textView.textColor = [UIColor colorWithR:67 G:83 B:83 A:1.0f];
textView.delegate = self;
textView.scrollEnabled = NO;
_commentTextView = textView;
[_textViewContainer addSubview:textView];
}
-(void)updateContentSize{
self.scrollView.contentSize = CGSizeMake(self.scrollView.contentSize.width, self.contentView.frame.size.height);
}
A scrollView a _contentView elemet tartalmazza, a contentView pedig az UITextView elemet. textView magassága növekszik, ahogy a felhasználó gépel, és a _contentView alja megegyezik a textView aljával.
