How can i display string instead of image in UIView? - ios

Question

Interface is define like this
#interface IGLDemoCustomView : UIView
#property (nonatomic, strong) UIImage *image;
#property (nonatomic, strong) NSString *title;
#end
While Implementation file look like this
#interface IGLDemoCustomView ()
#property (nonatomic, strong) UIImageView *imageView;
#property (nonatomic, strong) UILabel *titleLabel
#end
#implementation IGLDemoCustomView
- (instancetype)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self commonInit];
}
return self;
}
- (instancetype)initWithCoder:(NSCoder *)aDecoder
{
self = [super initWithCoder:aDecoder];
if (self) {
[self commonInit];
}
return self;
}
- (void)commonInit
{
[self initView];
}
- (void)initView
{
self.layer.borderColor = [UIColor colorWithRed:0.18 green:0.59 blue:0.69 alpha:1.0].CGColor;
self.layer.borderWidth = 2.0;
self.layer.masksToBounds = YES;
self.backgroundColor = [UIColor whiteColor];
self.alpha = 0.8;
UIImageView *imageView = [[UIImageView alloc] init];
imageView.contentMode = UIViewContentModeCenter;
[self addSubview:imageView];
self.imageView = imageView;
UILabel *titleLabel;
self.titleLabel = [[UILabel alloc]init];
titleLabel.center = self.center; // set proper frame for label
[self addSubview:titleLabel];
}
- (void)setImage:(UIImage *)image
{
_image = image;
self.imageView.image = image;
}
- (void)setString:(NSString *)title
{
self.title=title;
self.titleLabel.text = title;
}
- (void)setFrame:(CGRect)frame
{
[super setFrame:frame];
self.imageView.frame = self.bounds;
self.layer.cornerRadius = frame.size.height / 2.0;
}
#end
When i select image from the drop down menu it shows in the menu, but when i select any text from the drop down menu it doesnt show in the drop down list view.
Any clue will be highly appreciated.
Calling and setting string in the view
IGLDropDownItem *menuButton = strongSelf.dropDownMenu.menuButton;
IGLDemoCustomView *buttonView = (IGLDemoCustomView*)menuButton.customView;
buttonView.title = device.name;

Answer 1

You need to set a frame for the label
- (void)setFrame:(CGRect)frame
{
[super setFrame:frame];
self.imageView.frame = self.bounds;
self.titleLabel.frame = self.bounds;
self.layer.cornerRadius = frame.size.height / 2.0;
}
If you are expecting the text to wrap, you'll need to set the lineBreakMode and set numberOfLines to 0

Like you are having UIImageView you need to have a UILabel inside your UIView too.
#interface IGLDemoCustomView ()
#property (nonatomic, strong) UIImageView *imageView;
#property (nonatomic, strong) UILabel *titleLabel;
#end
- (void)initView
{
self.layer.borderColor = [UIColor colorWithRed:0.18 green:0.59 blue:0.69 alpha:1.0].CGColor;
self.layer.borderWidth = 2.0;
self.layer.masksToBounds = YES;
self.backgroundColor = [UIColor whiteColor];
self.alpha = 0.8;
UIImageView *imageView = [[UIImageView alloc] init];
imageView.contentMode = UIViewContentModeCenter;
[self addSubview:imageView];
self.imageView = imageView;
self.titleLabel = [[UILabel alloc]init];
titleLabel.center = self.center; // set proper frame for label
[self addSubview:titleLabel]
}
And in setString
- (void)setString:(NSString *)title
{
self.title=title;
self.titleLabel.text = title;
}
