Similar to Juice007, I had declared and initialized a C type variable in two different .m files (that weren't imported!)
BOOL myVar = NO;
however, this method of declaring and initializing a variable, even in .m, even in @implementation grants it global scope. Your options are:
Declare it as static, to limit the scope to class:
static BOOL myVar = NO;
Remove the initialization (which will make the two classes share the global var):
BOOL myVar;
-(void) init{
myVar = NO;
}
Declare it as a property:
@property BOOL myVar;
Declare it as a proper iVar in the @interface
@interface myClass(){
BOOL myVar;
}
@end
