This is better, however... if you pass an actual NSInteger or CGFloat to
the method, va_arg() should have a type of NSInteger or CGFloat, not
pointers to those types. Your code examples with it's printf style formats
is using the former, not the latter. Just to be clear, you can have all
these cases:
if ([myType isEqualToString:@"NSInteger"] ) {
myNSInteger = va_arg(myArgumentList,NSInteger);
} else if ([myType isEqualToString:@"NSInteger*"] ) {
pMyNSInteger = va_arg(myArgumentList,NSInteger*);
} else if ([myType isEqualToString:@"CGFloat"]) {
myCGFloat = va_arg(myArgumentList, CGFloat);
} else if ([myType isEqualToString:@"CGFloat*"]) {
pMyCGFloat = va_arg(myArgumentList, CGFloat*);
} ... etc
