stringByAppendingPathComponent和stringByAppendingString的区别

cyy:自我理解，不保证正确，但亲自试验确实可行：若用 stringByAppendingString  则需要手动在名称前加 “/”符号，而stringByAppendingPathComponent则不需要，它会自动添加

stringByAppendingPathComponent和stringByAppendingString的区别：

NSString *imagePath = [skinPath stringByAppendingString:[NSString stringWithFormat:@"/%@",imageName]];//stringByAppendingString是在skinPath加后缀的意思
NSString *imagePath = [skinPath stringByAppendingPathComponent:imageName];//stringByAppendingPathComponent是在skinPath后面加上“／”号连接imageName让它成为完整的路径
NSLog(@"imagePath:%@",imagePath);
