In my project, I get a number of warnings that are invalid, telling me that something or another "may not respond" to something, when in fact, it can. As an example, I get a lot of these:

warning: 'NSString' may not respond to '- stringByReplacingOccurrencesOfString:withString:'
warning: 'NSFileManager' may not respond to '-removeItemAtPath:error:'
warning: 'WebView' may not respond to '-mainFrameURL'

while are all Cocoa framework calls, which do work. In some instances, I've found that tracking down a header file and #importing it sometimes gets rid of the message, but not always (can't seem to get rid of the three shown here, ever.)


These are all methods added in Mac OS X 10.5. Check the SDK settings for your target.
