Comparing NSString in Objective-C
To compare two NSString objects in Objective-C, you can use the isEqualToString:
method. This method returns a Boolean value indicating whether the receiver and the specified string are equal.
Here's an example of how to use the isEqualToString:
method:
NSString *string1 = @"Hello";
NSString *string2 = @"World";
if ([string1 isEqualToString:string2]) {
NSLog(@"The strings are equal");
} else {
NSLog(@"The strings are not equal");
}
In this example, the isEqualToString:
method is used to compare string1
and string2
. If the strings are equal, the message "The strings are equal" will be printed. Otherwise, the message "The strings are not equal" will be printed.
Please note that the isEqualToString:
method performs a case-sensitive comparison. If you need to perform a case-insensitive comparison, you can use the caseInsensitiveCompare:
method instead.
I hope this helps!
