方法壹:最直接。
ns string * urlString = @ "/img/Baidu _ logo _ fqj _ 10 . gif "；
ns string * fileName =[urlString lastPathComponent]；
NSLog(@“% @”，文件名)；
方法二:按字符或時間串切分。
對象-C
ns string * link = @ "/img/Baidu _ logo _ fqj _ 10 . gif "；
ns string * filename =[[ns string alloc]init]；
NSArray * separated array =[[NSArray alloc]init]；
separated array =[link components separated bystring:@ "/]；
filename =[separated array last object]；
NSLog(@“% @”，separated array)；
NSLog(@“% @”，文件名)；
[文件名發布]；
方法3:將鏈接視為路徑。
ns string * urlString = @ "/img/Baidu _ logo _ fqj _ 10 . gif "；
NSArray * urlCom =[[NSArray alloc]init with array:[URL path components]]；
NSLog(@“% @”，[urlCom last object])；
【urlCom發布】；
方法四:NSRange。攔截二進制文件時非常方便。
ns string * urlString = @ "/img/Baidu _ logo _ fqj _ 10 . gif "；
NSString * fileName
ns range range =[urlString range of string:@ "/" options:NSBackwardsSearch]；
if (range.location！= NSNotFound)
{
fileName =[urlString substringromindex:range . location+1]；
if([[fileName lower casestring]hasSuffix:@”。gif"])
{
NSLog(@“% @”，文件名)；
}
