Question

我想循环遍历一个数组字符串，并按以下方式将它们添加到NSString：

NSMutableArray *emailsArray = [[NSMutableArray alloc] initWithObjects:@"One", @"Two", @"Three", nil];

for (id email in emailsArray {
    NSString *emails = ??; 
}

所以最后的NSString应该如下：

NSString *emails = @"One|Two|Three";

Answer 1

请使用[emailsArray componentsJoinedByString:@"|"]。

样品：

NSMutableArray *emailsArray = [[NSMutableArray alloc] initWithObjects:@"One", @"Two", @"Three", nil];
NSString *emails = [emailsArray componentsJoinedByString:@"|"];

在这里，您将拥有emails = @"One|Two|Three"。
