如何删除(从字符串

Question

可能重复:
iphone sdk - 从字符串中删除除数字0-9之外的所有字符

我有一个电话号码的字符串

mynumber = @"(334)687-6619";

我在用

NSString *phoneURLString = [NSString stringWithFormat:@"tel:%@", phoneNumber];
NSURL *phoneURL = [NSURL URLWithString:phoneURLString];
[[UIApplication sharedApplication] openURL:phoneURL];

拨打电话.但由于"(",")"我的方法无法拨打电话.

请建议我做一个正确的字符串

"1-800-555-1212"或类似的东西.

谢谢

Answer 1

您可以使用

NSString *s = @"(334)687-6619";
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"("];
s = [[s componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];

s = [s stringByReplacingOccurrencesOfString:@")" withString:@"-"];
NSLog(@"%@", s);

因此,它将取代"("与""和"替换")"与" - ".

谢谢.
