OR function in Objective-C

is there an OR function in Objective-C?

for example:

if(string1 == string2 || string开发者_StackOverflow3 == string 4)

|| doesnt seems to work.

Thanks.

|| is a valid Objectivc-C and C Operator. It should work.

Try is code:

if([string1 isEqualToString:string2] || [string3 isEqualToString:string4]) 
{
}

The or-operator || works fine, but the == operator doesn't work for C-strings nor for NSString if you want to test for string-equality. As written you only test for the pointers being equal.

Instead use:

• strcmp() for C-style strings
• -isEqualToString: for NSString
