问题 I have been wanting to apply different colors to my UISegmentedControl segments. Many people on here have been asking how to set tint color when you press on a certain segment. What i want to do is to set the tint color of each segment throughout the life of the application(or when the view appears on the screen). Scanning the questions on here, different people have pointed out that evidently in iOS 6 you cannot set the tintColor of each segment as such: - (void)viewDidLoad { [super

问题 I have been using iCloud in my apps for a while now and am recently having an issue where devices refuse to talk to each other. Or at least that's what I thought until I started logging the methods where the merging takes place. My persistentStoreCoordinator is set up as described in a previous question of mine. The problem is the following. When setting up my managedObjectContext , I add an observer to it to view the NSPersistentStoreDidImportUbiquitousContentChangesNotification notification

问题 I am fairly new to XCode - I'm designing an app with a single view that just displays a UIWebView that loads my jQuery mobile web site. I have the Default.png and Default@2x.png files for the Launch images in place. When I run the app on my test device or in the emulator, it shows my Launch Image, and then flashes a white screen while the UIWebView loads the first page. I know that I can change the background color and opacity so it will flash a different color than white, but I would like to

问题 I am using Core Data for managing data base into my app. I can not post the code here, because its too lengthy. But I guess that I can explain my problem in small line of code along with some snap shots. +(NSArray *)checkusernameandpassword:(NSString *)entityname username:(NSString *)username password:(NSString *)password { managedobjectcontext=[Singleton sharedmysingleton].managedobjectcontext; NSEntityDescription *entity=[NSEntityDescription entityForName:entityname inManagedObjectContext

问题 I have a view that is made to be displayed in landscape mode only, and is working well. But if you send the app to the background and then resume it, the notification center will appear in the orientation you had the device when resuming the app (usually portrait mode), so when I detect a swipe from left to right sometimes the notification center will appear. Any ideas how I can make the system know that it should show the notification center in landscape mode? EDIT : The view displays in

问题 I'm using the category to customize nav bar. My code is: - (void) drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetFillColor(context, CGColorGetComponents([self.tintColor CGColor])); CGContextFillRect(context, rect); } It works well, but not in iOS 5. I need nav bar color to be solid without any gradient. How should I do this? As I know, for iOS 5 the only way to replace drawRect method is to make a subclass, but is there any way to make all navigation

问题 A customer sent me a crash log from an iOS 5.0.1 (9A405) device. I'm running Xcode 4.2 on Snow Leopard. The system parts of the crash log call stack fail to symbolicate, and it seems that they're relevant to the crash; there are no iOS 5.0.1 symbols in Xcode. I don't have a 5.0.1 device, and I don't think I can install it, now that 5.1 is the latest. Is there a way for force-download symbols for a given iOS version in Xcode without plugging in a device? EDIT: seems like you can force a

问题 Inside the following function, I've used a block. But when I call this function, it is returned even before the block is executed. I understood that Block inturn uses the threads and executes separately so that the function doesnt wait for it to return. But, Is there any other way I could make the function execution wait, or any other way to achieve the functionality of this block without using the block itself ? -(int)findCurrentZip { CLLocation *userLocation = [[CLLocation alloc]
