How can I add a list (TableView) to a view without changing views, I want to show the list over the current view but in the middle of the view, so the original view will be showed also.
I tried with label...but gettign some problems adding tableView instead of label.
UIView *testView = [[[UIView alloc] initWithFrame:CGRectMake(0,0, 100, 100)autorelease];
testView.backgroundColor = [[UIColor grayColor] colorWithAlphaComponent:0.2f]; UILabel *label = [[[UILabel alloc] init] autorelease];
label.text = #"TEST";
[label sizeToFit];
[testView addSubview:label];
[self addSubview:testView ];

I have a UIPickerView which has a UIToolbar placed as a subview. The problem is when I click on the UIbarviewItem nothing happens. I am not sure why, but if I insert the UIToolbar as a subview to the main view ([self.view addSubview:toolbar]) the button works fine, but not as a subview for the uIPickerView?
Here is my code I used to create the uipickerview and the uitoolabr:
dateRangePickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, CGRectGetHeight(self.view.frame)-200, CGRectGetWidth(self.view.frame), 220)];
dateRangePickerView.showsSelectionIndicator = YES;
dateRangePickerView.hidden = NO;
[dateRangePickerView reloadAllComponents];
dateRangePickerView.showsSelectionIndicator = YES;
dateRangePickerView.delegate = self;
dateRangePickerView.dataSource = self;
[dateRangePickerView setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:dateRangePickerView];
// Add toolbar
toolBar= [[UIToolbar alloc] initWithFrame:CGRectMake(0, -44, CGRectGetWidth(self.view.frame), 44)];
[toolBar setBarStyle:UIBarStyleDefault];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered target:self action:#selector(selectDateRange)];
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
barButtonDone.tintColor=[UIColor blackColor];
[dateRangePickerView addSubview:toolBar];
Could anybody tell me where am I going wrong?
Thanks,
Peter
I decided instead of adding a subview to the UIPicker, I placed the UIPicker and UIToolbar in a UIView to keep everything together.
Thanks all for your help :)
I'm trying to create a simple scrollView inside a tableview cell. Just like on app store, but with simpler scrolling.
The scrollview is showing up but its not scrolling at all. I've tried whole first page on google and many stackoverflow questions, can't seem to find what I'm doing wrong.
if (indexPath.row==0) {
// Clearing out cell background
[cell setBackgroundColor:[UIColor clearColor]];
[cell.contentView setBackgroundColor:[UIColor clearColor]];
// Imageviews for scrollview
UIImageView *imageview1 = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,123)];
UIImageView *imageview2 = [[UIImageView alloc] initWithFrame:CGRectMake(320,0,320,123)];
imageview1.image = [UIImage imageNamed:#"flash2.png"];
imageview2.image = [UIImage imageNamed:#"IMG_2458.JPG"];
// setting up scrollview
self.scrollViewHeader = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320, 123)];
self.scrollViewHeader.scrollEnabled = YES;
self.scrollViewHeader.delegate = self;
[self.scrollViewHeader setUserInteractionEnabled:YES];
[self.scrollViewHeader setContentSize:CGSizeMake(320, 123)];
[self.scrollViewHeader addSubview:imageview1];
[self.scrollViewHeader addSubview:imageview2];
[cell.contentView addSubview:self.scrollViewHeader];
}
else{
// Normal table cells.
...
}
Thanks in advance for your answers.
In order for a scroll view to scroll, its content size must be greater than its bounds.
You have:
self.scrollViewHeader = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,320, 123)];
and then
[self.scrollViewHeader setContentSize:CGSizeMake(320, 123)];
In this case, they are both the same size, therefore it won't scroll. Do:
self.scrollViewHeader = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,160, 123)];
[self.scrollViewHeader setContentSize:CGSizeMake(320, 123)];
I have two views in my program. One is statusView, it's alpha is set to 0.8f. And below it is tableView. How do I disable statusView such way, that clicking on it would not click tableView. Settings userInteractionEnabled = false; didn't help.
Here is how i add views.
[self.view addSubview:_builded.view]; // obj with my tableView
info = [[Info alloc] init];
[self.view addSubview:info.view]; // statusView
If you add a subview like the following, the tableView underneath would not catch the user interaction.
UITableView *testTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
testTableView.delegate = self;
testTableView.dataSource = self;
[self.view addSubview:testTableView];
UIView *statusView = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 200, 200)];
statusView.backgroundColor = [UIColor redColor];
statusView.alpha = 0.8;
[self.view addSubview:statusView];
I have the following code in my XCode project for an iOS app I'm developing:
testLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0, 320, 480)];
UIFont *Font = [UIFont fontWithName:#"Arial" size:40];
[testLabel setFont:Font];
[testLabel setTextAlignment:UITextAlignmentCenter];
[testLabel setTextColor:[UIColor colorWithRed:(float) 55/255 green:(float) 41/255 blue:(float) 133/255 alpha:1.0]];
testLabel.text = #"Here We Go";
I am looking to put an image in that spot instead of the text. What do I need to replace this code with?
Either you make an image and put it in an UIImageView or you make a UIView subclass in which you will draw the text inside the drawRect method.
In the second case, in your drawRect you do this :
[self.yourStringProperty drawAtPoint:CGPointMake(100,150) withFont:[UIFont systemFontOfSize:14.0]];
or
[self.yourStringProperty drawInRect:rect withFont:[UIFont systemFontOfSize:14.0]];
Also, look HERE for a detailed explanation of these functions which can also take into account the available width, minimum sizes, line breaks, etc.
The answer above mine is the best with the second part: use a UIView and put either your label or a UIImageView inside it depending on what you want. Here's what it would look like with the image:
UIView *container = [[UIView alloc] initWithFrame:CGRectMake(<<your image frame here>>)];
UIImageView *image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"yourImage.png"]];
image.frame = CGRectMake(<<your image frame here>>);
[container addSubview:image];
[self.view addSubview:container];
In this code example, i am trying to produce the following view hierarchy
Window -> background image -> scroll view -> text view
All i see however is
Window -> background image
What am i missing please?
-(void) viewWillAppear:(BOOL)animated {
UIScrollView *scrollWindow = [[UIScrollView alloc]
initWithFrame:CGRectMake(30, 30, 440, 212)];
UITextView *scrollableText = [[UITextView alloc] init];
[scrollableText setEditable:NO];
[scrollableText setText:#"Why, hello there"];
[scrollWindow addSubview:scrollableText];
UIImage *backgroundImage = [[UIImage alloc] initWithCGImage:
[UIImage imageNamed:#"about_bg.png"].CGImage];
UIImageView *backgroundView = [[UIImageView alloc]
initWithImage:backgroundImage];
[backgroundView addSubview:scrollWindow];
[[self view] addSubview:backgroundView];
}
Andrew is right about not making the scroll view a subview of the background UIImageView view. But the scroll view is invisible. Only its content (scrollableText) will show. And you haven't set scrollableText's frame, so it's effectively invisible too. Init like so:
[scrollableText setEditable:NO];
[scrollableText setText:#"Why, hello there"];
[scrollableText setFrame:CGRectMake(0, 0, 100, 100)];
And you should see it.
What you need is this hierarchy:
Window
background image view
scroll view
text view
Try adding two subviews to your window, not shove them all as subviews into each other.''-
- (void) viewWillAppear:(BOOL)animated {
UIScrollView *scrollWindow = [[UIScrollView alloc] initWithFrame:CGRectMake(30, 30, 440, 212)];
UITextView *scrollableText = [[UITextView alloc] init];
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"about_bg.png"]];
scrollableText.editable = NO;
scrollableText.text = #"Why, hello there";
[scrollWindow addSubview:scrollableText];
[self.view addSubview:backgroundView];
[self.view addSubview:scrollWindow];
}
