您可以使用NSString的"componentsSeparatedByString"方法来完成此操作.

NSString * source =  @"hai-welcome";
NSArray * stringArray = [source componentsSeparatedByString:@"-"];
NSString * firstPart = [stringArray objectAtIndex:0]; // Contains string "hai"
NSString * secondPart =[stringArray objectAtIndex:1]; //Contans string "welcome"
