How can I check that the NSString ends with the certain character(.jpg)?

Question

I have a NSString object which is assigned this ("http://vspimages.vsp.virginia.gov/images/024937-02.jpg"). Can anybody tell me how to check whether the string ends with ".jpg"?

Answer 1

if ([[yourString pathExtension] isEqualToString:@"jpg"]){    //.jpg } 

or

if ([yourString hasSuffix:@".jpg"]){    //.jpg } 

Answer 2

appending to vladimir's answer, you may wish to make a case insensitive comparison. Here's how I did it:

if( [[yourString pathExtension] caseInsensitiveCompare:@"jpg"] == NSOrderedSame ) {   // strings are equal but may not be same case }
