Try with the string method - (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement;
尝试使用字符串方法 - (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement;
str=[str stringByReplacingOccurrencesOfString:@" " withString:@"+"];
