string-將一個字符串分割成多個字符串

將一個字符串分割成多個字符串

有一個字符串：

011597464952,01521545545,454545474,454545444|Hello this is were the message is.

我希望每串數字都能在不同string中，

NSString *Number1 = 011597464952 
NSString *Number2 = 01521545545
etc
etc
NSString *Message = Hello this is were the message is.

怎麼樣完整的將字符串分割？

最佳回答：

用-[NSString componentsSeparatedByString]:

NSString *str = @"011597464952,01521545545,454545474,454545444|Hello this is were the message is.";

NSArray *firstSplit = [str componentsSeparatedByString:@"|"];
NSAssert(firstSplit.count == 2, @"Oops! Parsed string had more than one |, no message or no numbers.");
NSString *msg = [firstSplit lastObject];
NSArray *numbers = [[firstSplit objectAtIndex:0] componentsSepratedByString:@","];

// print out the numbers (as strings)
for(NSString *currentNumberString in number) {
  NSLog(@"Number: %@", currentNumberString);
}
