iOS 整型转换警告"NSInteger' should not be used as format arguments; add an explicit cast to 'long' inste"

苹果app支持arm64以后会有一个问题：NSInteger变成64位了，和原来的int （%d）不匹配，会报如下warning，

Values of type ‘NSInteger’ should not be used as format arguments; add an explicit cast to ‘long’ instead

解决办法：
1、系统推荐方法 [NSString stringWithFormat:@“%ld”, (long)number];

2、强制转换 [NSString stringWithFormat:@”%d”, (int)number];

3、[NSString stringWithFormat:@“%@”, @(number)];
