Proper way to convert BOOL value into INT?

Everytime when I tried to convert BOOL value into int. INT value is showing -8 for True and 0 for False. Ideally it should return 1 for true.

I have tried all possible ways of conversion like

int val=Info.isattachementDownloadable;
int val=[[NSString stringWithFormat:@"%d", Info.isattachementDownloadable] intValue];
int val=(int)Info.isattachementDownloadable;

where Info.isattachementDownloadable return BOOL

In all ways its showing -8开发者_如何学Go for TRUE.

Any suggestion ?

Maybe that will help(thought i don't know why it may be needed in the first place)

NSInteger i = @(YES).integerValue;

Hope that it helps you.

It is much quicker to do it like this:

BOOL myBool = YES;
int myInt = (myBool ? 1 : 0);

myInt will be 1 if myBool is YES, and 0 if myBool is NO.

It is always possible to use the object-oriented wrapper around numeric primitives (e.g. C's int). So am I answering the question? both yes and no depending on your viewpoint. However, here is what I prefer to use when using BOOL as input:

NSNumber *numval = [NSNumber numberWithBool:Info.isattachementDownloadable];

And if you really need to use the primitive datatype:

int val = [numval intValue];

BOOL myBool;    
int myInt;
if (myBool) myInt = 1;
else myInt = 0;

You can just assign BOOL value to int since YES and NO are just shortcuts for 1 and 0. You can also perform maths operations on BOOLs. FYI, BOOLs can even hold values from -128 up to 127 since they are just typedefs for signed chars.

BOOL someBool = YES;
int intFromBool = someBool;
NSLog(@"%d", intFromBool);

intFromBool -= YES;
NSLog(@"%d", intFromBool);
