In many languages such as java, ruby, python cut in both the string into an array or an interval of the array elements to form a new array of string spacing. In fact NSArray also provide this functionality.

Use-componentsSeparatedByString: to cut points NSArray. Such as:


NSString * string = @ "one: two: three";
NSArray * aArray = [string componentsSeparatedByString :@":"];

By-componentsJoinedByString: NSArray to merge and create the various elements of a new string, such as:
string = [aArray componentsJoinedByString :@","];

Thus, the above array to each element on the "" split to form a string.
