[__NSCFString charValue]: unrecognized selector sent to instance?
My app uses FMDB and Mantle, everything works fine after iPhone 5 simulator, but crash before iPhone 5s, it looks like Bool Variable is the cause. But I can't figure out why everything works fine on iPhone 5, 6 and 6 plus.
@property (nonatomic, assign) BOOL isMyFan;
@property (nonatomic, assign) BOOL isMyFollow;
@property (nonatomic, assign) NSInteger cityID;
@property (nonatomic, assign) NSInteger provinceID;
@property (nonatomic, assign) NSInteger locationID;

ORIGINAL ANSWER: . If it works on iPhone 5S and up, it looks like a 32/64 bit issue, since all iPhones with 5S are 64 bit. More precisely, for a 32-bit system BOOL
there is signed char
, while under a 64-bit system - BOOL
.
You can read more here.
UPDATE: I am guessing your problem is dealing with the storage of BOOL values in collections. BOOL values stored in obj-c collections are wrapped in an NSNumber object since collections can only contain objects. You should use it like this:
NSDictionary *dict = @{@"BOOL_Key": [NSNumber numberWithBool:YES]};
BOOL myBool = [[dict objectForKey:@"BOOL_Key"] boolValue];
Or you can use @(YES)
instead [NSNumber numberWithBool:]
. If you don't use it boolValue
, you may get unpredictable results. Hope it helps.
