  • Android - Fill Layout with Buttons

    - by GuyNoir
    Just a quick question about how you would go about implementing this. I want there to be buttons at the bottom of the screen, but if the screen size is larger, more buttons would be added. For example, at a small screen size, there might be 4-5 buttons at the bottom, but if you ran it on a tablet or something similar, there would be maybe 20 buttons. Any suggestions? It can't scroll either, it just has to dynamically fill the layout with buttons. Thanks.

  • How can I make text in a UILabel non-centered?

    - by Sheehan Alam
    I have a UILabel: descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)]; [descriptionLabel setFont:[Utils getSystemFontWithSize:14]]; [descriptionLabel setBackgroundColor:[UIColor clearColor]]; [descriptionLabel setTextColor:[UIColor whiteColor]]; descriptionLabel.numberOfLines = 0; descriptionLabel.lineBreakMode = UILineBreakModeWordWrap; [self addSubview:descriptionLabel]; If the text is only 1 line long it will appear in the middle of the label. Is there anyway I can have the text display from the top left corner of the label instead of the middle center?

  • How to deal with callback to your UIController after your UIController unloads?

    - by erotsppa
    Suppose your controller is a table view and one of the cells you are going off to do a length task (say download a thumbnail) to be viewed in the cell. Typically you would have the network call do a callback to your controller when it is done downloading. The callback can then reload the table or do some other form of UI update (hides a spinner etc). However, what if the controller is unloaded? Say the user navigated away from this controller and it got released? What happens? Will the callback still work despite the controller now not in memory? Also, if the callback operates on some objects (say the UITableView) what happens when the controller is deallocated? I suppose the controller can release all the objects and the callback would just be calling methods on nil to prevent crash. But is this the convention?

  • How to set clickable and highlightable a View?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • Setting a background drawable for a dialog?

    - by user291701
    Hi, Tried posting this at android dev, wanted to go here too in case anyone knows. I'm trying to supply a custom background drawable for a dialog. I've created the following in my styles.xml file: <style name="CustomDlg" parent="@android:style/Theme.Dialog"> <item name="android:windowBackground">@drawable/my_background</item> </style> This works fine on 1.6+. On my g1 running 1.5 (and the 1.5 emulator) the drawable is used, but the area around the dialog is opaque black instead of being translucent. Is there something I'm missing here, or is this a bug with 1.5? Any work arounds? Is 1.5 just the ie6 of Android? Thanks

  • Documented process for using facebook connect for the iPhone to upload photos

    - by Corey Floyd
    After looking I did come accross this post on the facebook forums: link They are feeding the facebook object a UIImage. That seems logical, but where is this documented? The API documentation is generalized to all platforms. Where are the iPhone specific requirements for arguments and their data types? Thanks **Update***** I still have not came across any API docs pertaining to Cocoa. I did, however, gather the information I needed by piecing together forum information, Facebook sample code, and some glue. Hopefully they'll issue something a little more concrete over the next few months.

  • UITableViewCell height with 0 rows

    - by Typeoneerror
    I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.

  • What method of UIView gets called when instantiated from a NIB?

    - by retailevolved
    I have a simple custom view that is connected via outlet to a NIB. For this particular view, there are actions that I would like to perform on the view when it is initialized, no matter what NIB it is on. Trouble is, neither the (id)init or the (id)initWithFrame:(CGRect)frame methods are getting called on the custom view. Which method gets called on a UIView when it is instantiated from a NIB? I would just use the view controller and viewDidLoad method except that this particular view appears on a lot of different NIBs.

  • How does one create an elegant iPhone GUI?

    - by jrtc27
    This is just one of those things where you feel like your own design is utterly terrible, and that all of the other apps have a beautiful design. This question is just about how you would go about creating a user interface that a user would actually want to use?

  • Padding List Items?

    - by Lee Olayvar
    I have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded. Thanks to any replies!

  • Error with custom Class definition in protocol

    - by Greg
    I'm trying to set up a custom delegate protocol and am getting a strange error that I don't understand. I wonder if someone could point out what I'm doing wrong here (I'm still new to Ob-C and protocol use)... The situation is that I've built my own URLLoader class to manage loading and parsing data from the internet. I'm now trying to set up a protocol for delegates to implement that will respond to the URLLoader's events. So, below is my protocol... #import <UIKit/UIKit.h> #import "URLLoader.h" /** * Protocol for delegates that will respond to a load. */ @protocol URLLoadResponder <NSObject> - (void)loadDidComplete:(URLLoader *)loader; - (void)loadDidFail:(URLLoader *)loader withError:(NSString *)error; @end However, I'm getting the following error for both method signatures: Expected ')' before 'URLLoader' I feel like I must be overlooking something small and silly. Any help folks could offer would be greatly appreciated! Whoops ... it was pointed out that I should include URLLoader.h. Here it is: #import <Foundation/Foundation.h> #import "URLLoadResponder.h" /** * URLLoader inferface. */ @interface URLLoader : NSObject { NSString *name; NSString *loadedData; NSMutableData *responseData; NSObject *delegate; BOOL _isLoaded; } @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSString *loadedData; @property (nonatomic, retain) NSObject *delegate; - (void)loadFromURL:(NSString *)url; - (void)addCompleteListener:(id)observer selector:(SEL)sel; - (void)removeCompleteListener:(id)observer; - (void)parseLoadedData:(NSString *)data; - (void)complete; - (void)close; - (BOOL)isLoaded; + (NSURL *)makeUrlWithString:(NSString *)url; + (URLLoader *)initWithName:(NSString *)name; @end
