  • SQLite - a smart way to remove and add new objects

    - by Ilya
    Hi, I have a table in my database and I want for each row in my table to have an unique id and to have the rows named sequently. For example: I have 10 rows, each has an id - starting from 0, ending at 9. When I remove a row from a table, lets say - row number 5, there occurs a "hole". And afterwards I add more data, but the "hole" is still there. It is important for me to know exact number of rows and to have at every row data in order to access my table arbitrarily. There is a way in sqlite to do it? Or do I have to manually manage removing and adding of data? Thank you in advance, Ilya.

  • Heterogeneous NSTreeController

    - by andyvn22
    I have an NSTreeController (supplying content to an NSOutlineView). I'd like the top-level objects to be of one class, and all other objects (so, children at any level) to be of another. What's the best way to go about this? I'll need to somehow change the behavior of at least add, addChild, insert, and insertChild, I suppose. I was hoping, though, to find a simple way to account for this in only one location, rather than changing four separate methods.

  • View outlet not set with UINavigationController

    - by Sheehan Alam
    I have a NIB that contains a UINavigationController which has a UIViewController. The UIViewController is being loaded externally from another nib. I am unable to set the view property thus I get the error: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "LBRootViewController" nib but the view outlet was not set.' How can I set my view property correctly?

  • iPhone metering problems

    - by Eric Christensen
    When I'm recording an AVAudioRecorder object, I repeat a chunk of code via an NSTimer that includes: [soundrecording updateMeters]; NSLog(@"channel 0 average:%f, peak:%f",[soundrecording averagePowerForChannel:0],[soundrecording peakPowerForChannel:0]); NSLog(@"channel 1 average:%f, peak:%f",[soundrecording averagePowerForChannel:1],[soundrecording peakPowerForChannel:1]); When I'm recording a mono file, the peak power for channel 0 is just what you'd expect, a float from -160 to 0. But average power for channel 0 is always zero. (And, of course, the values for channel 1 are both zero.) When I'm recording a stereo file, both the average and peak values for both channels are as expected. Any thoughts on why, when recording a mono file, the average value for channel 0 isn't returning correctly, even though the peak is? Thanks!

  • Mac OS X software always order files alphabetically rather than by type.

    - by george
    I have noticed many Mac applications sort the files alphabetically rather than by type. A good example would be Coda by panic.com. The files in the file menu are organized alphabetically. I requested for them to add the feature to organize files by type, and they've said that it's a Finder thing. So I looked at other applications to see if they were organizing by type. I noticed Dreamweaver CS4 had this same problem and now including Dreamweaver CS5. There has to be something in the Mac that does this and that I can modify. I played with Spotlight and it now displays its files by type (thinking that's what I can do) but it didn't take effect in other applications. What library are these applications using to display a file menu for their files? here is an example-- file menu layout of coda by panic.com. (i couldnt post another link because it wouldnt let me). can you see how everything is organised alphabetically rather than by folder? i just want the file menu to show all folders first then all the files. 1) http://www.iaddesign.com/coda.png there must be a way to modify mac to let me to do this.

  • invalid context 0x0 under iOS 7.0 and system degradation

    - by Alex
    I've read as many search results I could find on this dreaded problem, unfortunatelly, each one seems to focus on a specific function call. My problem is that I get the same error from multiple functions, which I am guessing are being called back from functions that I use. To make matters worse, the actual code is within a custom private framework which is being imported in another project, and as such, debugging isn't as simple? Can anyone point me to the right direction? I have a feeling I'm calling certain methods wrongly or with bad context, but the output from xcode is not very helpful at this point. : CGContextSetFillColorWithColor: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update. : CGContextSetStrokeColorWithColor: invalid context 0x0. This is a serious error.

At which point they spawn multiple times, until the keyboard won't provide any input. Touch events are still registered, but system slows down, and eventually may lead to unallocated object errors.

  • CGPDFContextCreateWithURL not correctly creating context

    - by mjdth
    Using the following code, the ctx is not correctly being created. It remains nil: #import <QuartzCore/QuartzCore.h> @implementation UIView(PDFWritingAdditions) - (void)renderInPDFFile:(NSString*)path { CGRect mediaBox = self.bounds; CGContextRef ctx = CGPDFContextCreateWithURL((CFURLRef)[NSURL URLWithString:path], &mediaBox, NULL); CGPDFContextBeginPage(ctx, NULL); CGContextScaleCTM(ctx, 1, -1); CGContextTranslateCTM(ctx, 0, -mediaBox.size.height); [self.layer renderInContext:ctx]; CGPDFContextEndPage(ctx); CFRelease(ctx); } @end In the console it shows: <Error>: CGPDFContextCreate: failed to create PDF context delegate. I've tried several different paths so I'm fairly certain that is not the problem. Thanks for any advice!

  • MPMoviePlayerController doesn't implement MPMediaPlayback protocal as advertised?

    - by goren
    I'm trying to use the MPMediaPlayback protocol's currentPlaybackRate() to slow down a video. I'm confused though as the class MPMoviePlayerController states that: You can control most aspects of playback programmatically using the methods and properties of the MPMediaPlayback protocol, to which this class conforms. Except just above in the header here: http://developer.apple.com/iphone/library/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/MPMoviePlayerController/MPMoviePlayerController.html it doesn't seem to. All I want to do is slow down the playback rate for a video.

    - by cannyboy
    A form is pushed onto the view. The form has several required fields. Also the form needs to be validated. I want to intercept the back button's click to check if the fields have been filled in, and validate the form. How would I intercept the button's click, and make sure it doesn't pop to the previous screen?

  • Clipped UITextField with UITextFieldAlignmentRight

    - by Typeoneerror
    Got a small problem with UITextField. I have a simple UITextField and when I set the textAlignment property to "right", it gets clipped by 1-2 pixels. It looks shite so I'm hoping someone has an idea of how to remedy this. I've tried setting the frame to integers to prevent them from being on .5 pixels. - (UITextField *)textControlForSetting:(NSDictionary *)settings { CGRect frame = CGRectIntegral(CGRectMake(100.0f, 0.0f, 170.0f, 44.0f)); UITextField *textField = [[[UITextField alloc] initWithFrame:frame] autorelease]; NSString *defaultValue = [settings objectForKey:kDefaultValueKey]; NSString *currentValue = [prefs objectForKey:[settings objectForKey:kSettingKey]]; textField.tag = settingsCounter; textField.delegate = self; textField.textAlignment = UITextAlignmentRight; textField.font = [UIFont fontWithName:@"HelveticaNeue" size:14.0f]; textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; textField.placeholder = (currentValue != nil) ? currentValue : defaultValue; settingsCounter++; return textField; }

  • iPhone: [subview release] removes my subview from the display

    - by Stefan Klumpp
    I have these two pieces of code. The first one works perfectly: UIView *tmp = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 60.0f, 296.0f, 44.0f)]; [self.dynamicView addSubview:tmp]; [tmp release]; The second one is pretty much the same, but the view doesn't show up. CommentBox *commentBox = [[CommentBox alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 296.0f, 44.0f)]; [self.dynamicView addSubview:commentBox]; [commentBox release]; // Why does this remove the view? If I remove the [commentBox release] the view surprisingly appears. But I don't see a different between these two code snippets. The init for the CommentBox looks like this: - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Load the nib: NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"CommentBox" owner:self options:nil]; self = [nibObjects objectAtIndex:0]; } return self; }

  • NSDateFormatter incorrect date on simulator, correct date on device

    - by Rudiger
    Hi, Im building a calendar and to find out the first day of the month I do [formatter setDateFormat:@"e"]; int startDay = [[formatter stringFromDate:newDate] intValue]; On the device this works correctly and the 1st of the month is on the correct day. But on the simulator it is the day after. Although it doesn't overly matter about the simulator it is kind of driving me crazy thinking I've done something wrong. I tried to set the locale of the formatter but no difference, nor i think should it. Can anyone shed some light on this? On a side note is there a better way to build a calendar than this?

  • How-to build a droplet application in Xcode4?

    - by Josh
    In Xcode3 there used to be a template to build "Droplet" Applications (head/nibless apps that would throw whatever dropped at them at an "on open" Applescript method). In Xcode4 this template is unfortunately gone. What are the required steps to setup an xcode4 droplet project? modify the info.plist i guess to make the app handle drops get rid of the nib (also involves changes in main.m and both AppDelegate.h and AppDelegate.m i guess) Maybe somebody even still has Xcode3 installed and could create an empty applescript droplet app and upload it somewhere? that would be very interesting. thanks! (or is there maybe even a way to export an app bundle created with the AppleScript Editor to Xcode?)

  • Create a Editable Grid View as in iBooks

    There have been some similar questions asked regarding Grid views, but none have been sufficiently answered (some have been left unanswered as the SDKs were under NDAs at the time). The question is: Can anyone direct me towards a tutorial, or explain to me what steps to take to create a Grid View similar to iBooks, or the Yahoo! Entertainment app on the iPhone? Here's a screenshot of what I mean.

  • Incorrect decrement of the reference count

    I have the following problem: In one flow of the execution I use alloc, and on the other flow, alloc is not needed. At the end of the if statement, in any case, I release the object. When I do 'build and Analize' I get an error: 'Incorrect decrement of the reference count of an object is not owned by the caller'. How to solve that? UIImage *image; int RandomIndex = arc4random() % 10; if (RandomIndex<5) { image = [[UIImage alloc] initWithContentsOfFile:@"dd"]; } else { image = [UIImage imageNamed:@"dd"]; } UIImageView *imageLabel =[[UIImageView alloc] initWithImage:image]; [image release]; [imageLabel release];
