add overflow/negative support for NSRange
1: negative value
- NSUInteger > NSIntegerMax
2: overflow
- (a+ b) > a
remove unused swizze for NSDictionary objectForKey:
more class cluster support
NSArray
__NSArrayI_Transfer, __NSArrayReversed, __NSFrozenArrayM, __NSCFArray
NSString
NSTaggedPointerString, __NSCFString, _NSCFConstantString
NSData
NSConcreteData, NSConcreteMutableData, _NSZeroData, _NSInlineData, __NSCFData
Compile NSObjectSafe.m with -fno-objc-arc, otherwise it will cause strange release error: [UIKeyboardLayoutStar release]: message sent to deallocated instance
Conflict with MultiDelegate
Swizzle commonly used function of Foundation container to prevent nil crash
Hook forwardInvocation to catch unrecognized selector exception
Assert in Debug and log in Release
involve NSObjectSafe.h/NSObjectSafe.m as build phases
NSSafeProxy: unrecognized selector [print:] sent to A
@interface A : NSObject
- (void)print:(NSString*)msg;
