Notice: This answer only applies for PhoneGap version 1.x and below. From version 2.x onwards, whitelist configuration is done via cordova.xml. You have to add allowed URLs into PhoneGap.plist’s (or Cordova.plist) ExternalHosts array. For example, if you want to allow access to this URL http://www.myhost.com/path/file, then add www.myhost.com as a new entry to ExternalHosts array. … Read more
I have found the answer. I had a UITapGestureRecognizer set for myTableView’s superView. This overrode the selection call. Credit to whoever suggested that that might be it. Your answer was deleted before I could mark it correct. Set the cancelsTouchesInView property to NO on the gesture recogniser to allow the table view to intercept the … Read more
It’s been my experience that Xcode occasionally gets confused about which signing certificate to use. I got into the habit of quitting and restarting Xcode after any change to the code signing settings (and doing a clean build) to work around this problem.
You need to divide by 255.0 Because I hardly ever use values between 1.0 and 0.0, I created a very simple UIColor category that does the messy looking division by itself: (from http://github.com/Jon889/JPGeneral) //.h file @interface UIColor (JPExtras) + (UIColor *)colorWithR:(CGFloat)red G:(CGFloat)green B:(CGFloat)blue A:(CGFloat)alpha; @end //.m file @implementation UIColor (JPExtras) + (UIColor *)colorWithR:(CGFloat)red G:(CGFloat)green B:(CGFloat)blue … Read more
As in most languages the format is %.2f you can see more examples here Edit: I also got this if your concerned about the display of the point in cases of 25.00 { NSNumberFormatter *fmt = [[NSNumberFormatter alloc] init]; [fmt setPositiveFormat:@”0.##”]; NSLog(@”%@”, [fmt stringFromNumber:[NSNumber numberWithFloat:25.342]]); NSLog(@”%@”, [fmt stringFromNumber:[NSNumber numberWithFloat:25.3]]); NSLog(@”%@”, [fmt stringFromNumber:[NSNumber numberWithFloat:25.0]]); } 2010-08-22 … Read more
MyViewClass *myViewObject = [[[NSBundle mainBundle] loadNibNamed:@”MyViewClassNib” owner:self options:nil] objectAtIndex:0] I’m using this to initialise the reusable custom views I have. Note that you can use “firstObject” at the end there, it’s a little cleaner. “firstObject” is a handy method for NSArray and NSMutableArray. Here’s a typical example, of loading a xib to use as a … Read more
You can take a screenshot of any view or whole screen of the iPhone app with below method – (UIImage *)captureView { //hide controls if needed CGRect rect = [self.view bounds]; UIGraphicsBeginImageContext(rect.size); CGContextRef context = UIGraphicsGetCurrentContext(); [self.view.layer renderInContext:context]; UIImage *img = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return img; } And call it like bellow… UIImage *tempImageSave=[self captureView]; and … Read more
One of my work had a requirement to have an accordion view but having multiple levels of expansion and collapse of cells like you open/ close your directory structure. I did a sample on that, I was able to achieve the desired result. The basic concept is the same, I am using the deleteRowsAtIndexPath and … Read more
This is an interesting problem. We want to drag an object, but constrain it to lie on a CGPath. You said you have “a simple oval shape”, but that’s boring. Let’s do it with a figure 8. It’ll look like this when we’re done: So how do we do this? Given an arbitrary point, finding … Read more
My general advice: never, ever modify the default anchorPoint (0.5f, 0.5f) unless you have a really good understanding of what it does and how it helps you accomplish things. In all other cases, modify the position property. Especially if you do bounding box or radius based collision detection, modifying the anchor point is counter-productive. Let’s … Read more
