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"?

Cocoa Solutions

Solution 1 - Cocoa

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

or

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

Solution 2 - Cocoa

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
}

Solution 3 - Cocoa

NSPredicate *fltr = [NSPredicate predicateWithFormat:@"self ENDSWITH '.png' AND self BEGINSWITH[c] %@",@"img_"];
if([fltr evaluateWithObject:strPath])
{
	// string matched....
}
