I am getting this Error :
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MasterViewController setRefreshControl:]: unrecognized selector sent to instance 0x2681e0'
How to resolve this issue because in simulator my app is running but on device with the same code my app is not running.
I hope your simulator is iOS6 Simulator and the device in which you tried to run may have a lower OS version ..right?
.
From UIRefreshControl Class Reference,
Availability : Available in iOS 6.0 and later.
Refresh control is new to iOS6. So if you want to support iOS5, the best thing to do is check if the refresh control class exists (you can use NSClassFromString ), and if it doesn't exists either not use it or use an alternative.

I have a date picker in my app and it was working fine up until I updated to the latest Xcode.
Now when I use it it crashes and gives this error.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[_UIDatePickerMacCompactView _setTextColor:]: unrecognized selector sent to instance 0x11135ae50'
This is an app that is on iOS and Mac OS using catalyst.
The date picker works fine on the iOS devices but crashed like this on the Mac version.
Has anyone got any idea on what may be happening, I cannot find the UIDatePickerMacCompactView in there files anywhere.
Just by reading the error message, are you setting the text color as UIColor instead of NSColor by chance. I have little experience with Catalyst so I might be wrong but that's my 2 cents.
I am testing my music application compatibility on IOS7 by running it on Xcode 5 iPhone simulator(IOS7) but it crashes on retrieving all the music items using following code.
MPMediaQuery *allSongs = [[MPMediaQuery alloc] init];
NSArray *itemsFromGenericQuery = [allSongs items]; // Here application crashes
Crash log :
[__NSCFNumber libraryCompletionHandler]: unrecognized selector sent to instance 0xdd66840
This is snapshot for the threads running at the time of crash:
I am suspecting that there is some bug in Xcode5..!
EDIT : I could run the same application using Xcode 4.6.3 on simulator/device without any issue/crash.
[__NSCFNumber libraryCompletionHandler]: unrecognized selector sent to instance 0xdd66840
This error says that an object of type NSNumber was passed the message -libraryCompletionHandler. NSNumber doesn't have a -libraryCompletionHandler method, hence the crash. Obviously, something bad is going on.
Usually this is an indication of a bad cast, or a zombie. In this case, I would suspect a zombie object.
Congratz, you may have found a defect in the iOS 7 Simulator. Woo Hoo!
I am suspecting that there is some bug in Xcode5..!
There are clearly some bugs in the developer preview versions of Xcode 5, but it sounds like it's your app that's crashing rather than Xcode or the simulator itself. That would lead one to believe that the problem is more likely to be either in your app, or possibly in the operating system.
[__NSCFNumber libraryCompletionHandler]: unrecognized selector sent to instance 0xdd66840
Bad pointers are a common cause of unrecognized selector errors, especially when they involve classes that don't seem to be involved in the code that's crashing. Turn on NSZombieEnabled and set a breakpoint on all exceptions to track down the problem.
Maybe it's the project settings
Try to add -ObjC
I have been working with PhoneGap to access the camera, which works locally when built to the iPhone, but when I upload to TestFlight, the same method fails and gives me the following:
'NSInvalidArgumentException', reason: '[__NSCFString JSONObject]'
The arguments that are being passed are as follows:
[["Camera1856949628","Camera","takePicture",[25,0,1,100,100,1,0,false,false,false,null,0]]]
From what I gather its failing in CDVJSON.m when converting an NSString to JSONObject which in turn is an NSArray.
Any suggestions on what might be causing this?
Because your code don't use the JSONObject until runtime. So CDVJSON.m didn't linked in the app.
Fixed the issue by adding "Other Linker Flags: -all_load" in your project. As suggested by this answer: https://stackoverflow.com/a/17581430/2570865
I wanted to set the setLaunchPath: #"/bin/ps" for my iPhone application what actually it will do? Application crashes and will give the error as - Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'launch path not accessible'
* First throw call stack:
"setLaunchPath" exists in NSTask under MacOS... perhaps it exists under iOS, but it is not documented and certainly wouldn't be allowed for sandboxed apps that get submitted to the Apple App Store.

but when i am using ios 5.0 ipod for run application, is working fine with custom calender.
so please suggest me what is the is problem with ios 4.3.3.
Your error shows that you might have used something like this
[EKEventStore sources]
Am I right? If yes,
then apple doc says
sources
Returns an unordered array of source objects.
(NSArray *)sources
Return Value An unordered array of EKSource objects.
Availability Available in iOS 5.0 and later. Declared In
EKEventStore.h
So it is available in iOS 5.0 & later.
