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];

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 created a custom UINavigationBar which is a tiny bit taller than Apples default navigation bar.
I can’t seem to find a way to move the UIBarButtonItem down to be directly centered between the two dashed lines.
Is there an easy way to do this? I’ve tried creating a custom button but had no success. Ideally I would just like to move the default back button down a couple of pixels.
Code used to create UINavigationBar, custom header image and UIBarButtonItem:
//Create image for navigation background
UIImage *NavigationPortraitBackground = [[UIImage imageNamed:#"navbackground.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage: NavigationPortraitBackground
forBarMetrics:UIBarMetricsDefault];
//Centered title image
UIImageView *headerImage = [[UIImageView alloc] initWithImage: [UIImage imageNamed: #"hometitle.png"]];
[headerImage setFrame: CGRectMake(0, 0, 180, 49)];
self.navigationItem.titleView = headerImage;
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] init];
[backBarButtonItem setTintColor: [UIColor colorWithRed:0 green:69.0/255 blue:118.0/255 alpha:1]];
[backBarButtonItem setStyle: UIBarButtonItemStylePlain];
self.navigationItem.backBarButtonItem = backBarButtonItem;
[backBarButtonItem release];
Thanks in advance,
Create the UIBarButtonItem using a custom view. This custom view will be a UIView with the actual UIButton (as a subview) placed x pixels from the top (x=the number of pixels you want to move it down).
sorry
UIButton *myButton1 = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton1 setImage:[UIImage imageNamed:#"back.png"] forState:UIControlStateNormal]; myButton1.showsTouchWhenHighlighted = YES;
myButton1.frame = CGRectMake(0.0, 3.0, 50,30);
[myButton1 addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithCustomView:myButton1];
self.navigationItem.leftBarButtonItem = leftButton;
I am trying to create a view in iOS to let the user know their data is loading... it should have about a 200x200 Rounded-corner box in the middle with a spinner and the words "Data Loading..." and a transparent background.
This all is working except my 200x200 rounded-corner box is also transparent.
Here is the code I am using:
UIView *loadingDataView = [[UIView alloc] initWithFrame:CGRectMake(0, 44, 320, 367)];
loadingDataView.alpha = 0.4;
loadingDataView.backgroundColor = [UIColor clearColor];
UIView *viewWithSpinner = [[UIView alloc] initWithFrame:CGRectMake(110, 106, 100, 100)];
[viewWithSpinner.layer setCornerRadius:15.0f];
viewWithSpinner.backgroundColor = [UIColor blackColor];
UILabel *msg = [[UILabel alloc] initWithFrame:CGRectMake(5, 75, 90, 20)];
UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(5, 5, 90, 70)];
spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
[spinner startAnimating];
msg.text = #"Data Loading";
msg.font = [UIFont systemFontOfSize:14];
msg.textAlignment = UITextAlignmentCenter;
msg.textColor = [UIColor whiteColor];
msg.backgroundColor = [UIColor clearColor];
viewWithSpinner.opaque = NO;
viewWithSpinner.backgroundColor = [UIColor blackColor];
[viewWithSpinner addSubview:spinner];
[viewWithSpinner addSubview:msg];
[loadingDataView addSubview:viewWithSpinner];
[self.view addSubview:loadingDataView];
Thanks.
No exactly an answer to your question, but check out the open source MBProgressHUD. It aims to be an open source replacement for the private UIProgressHUD class, and is exactly what you're trying to do.
The solution for your problem is that you should remove the alpha attribute of 0.4, that's what's turning your round view transparent, if your view is set to clearColor (this is not really a color, it just makes the view transparent) it makes no sense to add an alpha of 0.4. If what you want is a semi-transparent view surrounding your black rounded view, you should do the following:
[loadingDataView setBackgroundColor:[UIColor colorWithRed:1 green:1 blue:1 andAlpha:0.4]];
That will give you something whiteish kinda grayish, that should work.
However, I would recommend you to use the GIDAAlertView Class I developed, you can get the source and an example app on my GitHub:
It takes about 3 lines to get it working:
GIDAAlertView *spinnerAlert=[[GIDAAlertView alloc] initAlertWithSpinnerAndMessage:#"GIDAAlertView Spinner"];
//Show it ...
[spinnerAlert presentAlertWithSpinner];
//Later in your code, hide it
[spinnerAlert hideAlertWithSpinner];
This is how it looks like.
you are telling it to be clear...
loadingDataView.backgroundColor = [UIColor clearColor];
What do you want it to be black?
I am trying to show into the header of my UITableViewController a title and under it an image illustrating the title. The next code (written into the viewDidLoad method) shows only the image, and this image over the rest of the table sections. How I can fix it to do what I want?
// Creates a header view.
UIView *containerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)] autorelease];
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 40)] autorelease];
headerLabel.text = self.name;
headerLabel.textColor = [UIColor blackColor];
headerLabel.font = [UIFont boldSystemFontOfSize:16];
headerLabel.backgroundColor = [UIColor clearColor];
GRect imageRect = CGRectMake(0.0f, 0.0f, 320.0f, 109.0f);
UIImageView *headerImage = [[UIImageView alloc] initWithFrame:imageRect];
UIImage *image = [UIImage imageNamed:self.imagePath];
[headerImage setImage:image];
headerImage.opaque = YES;
[containerView addSubview:headerLabel];
[containerView addSubview:headerImage];
self.tableView.tableHeaderView = containerView;
Thanks for reading.
Just adjust the views' frames accordingly. The container view's frame must be tall enough to contain the label and image view, and the image view's y coordinate must be set so that it is positioned below the label. The frame rects you are using in your code do not match.
How can I create and position a new imageview in objective-c?
Thanks!
I tried this but it doesnt seem to do anything...
-(void)drawStars{ //uses random numbers to display a star on screen
//create random position
int xCoordinate = arc4random() % 10;
int yCoordinate = arc4random() % 10;
UIImageView *starImgView = [[UIImageView alloc] initWithFrame:CGRectMake(xCoordinate, yCoordinate, 58, 40)]; //create ImageView
starImgView.image = [UIImage imageNamed:#"star.png"];
[starImgView release];
I placed this method in my viewcontroller. I see some CG stuff do I need to import core graphics or something? (what is core graphics anyway?)
You are asking about iPhone image view. Right? Then try this
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)];
This will create an image view of 100 x 50 dimension and locating (10, 10) of parent view.
Check the reference manual for UIImageView and UIView. You can set an image by using image property of imageView.
imgView.image = [UIImage imageNamed:#"a_image.png"];
And you can use the contentMode property of UIView to configure how to fit the image in the view. For example you can use
imgView.contentMode = UIViewContentModeCenter to place the desired image to the center of the view. The available contentModes are listed here
You haven't added your view as a subview to another view, meaning it isn't in the view hierarchy.
Assuming you are doing this in a view controller, it might look something like:
[self.view addSubview: imgView];
(void)viewDidLoad {
[super viewDidLoad];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.layer.frame.size.width, self.view.layer.frame.size.height)];
imgView.image = [UIImage imageNamed:#"emptyCart.jpeg"];
imgView.backgroundColor = [UIColor whiteColor];
imgView.contentMode = UIViewContentModeCenter;
[self.view addSubview: imgView];
}
I had problem with passing the value NSSArray to NSString,
I got the answer:
//Display all images....
NSString *imgstring= [self.allimages objectAtIndex:indexPath.row];
cell.myimages.image=[UIImage imageNamed:imgstring]; //displaying Images in UIImageView..noproblem.
// Display all numbers...
cell.mylables.text=[NSString stringWithFormat:#"%#", [mysetobjectAtIndex:indexPath.row ]]; //showing results fine ArghyA..
