if(lyricsId == areleased.trackId)
{
----------;
----------;
}
when i am working with above code it does not entered into that loop So, I used the below code,then it entered into the loop and i got out put.
if([lyricsId isEqualToString:areleased.trackId])
{
----------;
----------;
}
Is there any difference between == and isEqualToString.
lyricsId
and arelease.trackId
are (I presume) of type NSString*
. The ==
simply compares the pointers, which will usually be different even if their contents are the same. The isEqualToString
method compares their contents.
==
将比较指针(地址)的相等性,而isEqualToString:
将比较一个字符串是否等于另一个字符串。
