iOS 筆記-Data argument not used by format string的警告處理

標籤：

 NSError *error;

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:Online_Case_Lists]];

    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    NSArray *caselistarray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];

    NSLog(@"列表",caselistarray);

 

如上代碼~出現了這個警告，其實只是一時疏忽導致，沒有寫明輸出的caselistarray的類型

改一下就好了。

 NSError *error;

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:Online_Case_Lists]];

    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    NSArray *caselistarray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];

    NSLog(@"列表%@",caselistarray);
