How to see if an NSString starts with a certain other string?
Try this: if ([myString hasPrefix:@"http"]).
By the way, your test should be != NSNotFound instead of == NSNotFound. But say your URL is ftp://my_http_host.com/thing, it'll match but shouldn't.
I like to use this method:
if ([[temp substringToIndex:4] isEqualToString:@"http"]) { //starts with http}or even easier:
if ([temp hasPrefix:@"http"]) { //do your stuff}
If you're checking for "http:" you'll probably want case-insensitive search:
NSRange prefixRange = [temp rangeOfString:@"http" options:(NSAnchoredSearch | NSCaseInsensitiveSearch)];if (prefixRange.location == NSNotFound)
