在label.text中显示表的行数

Question

嗨我有一张桌子，想要在label.text中显示表格中有多少项，所以将行数转换为文本字符串

Answer 1

您需要计算模型（数组或字典计数）并形成字符串：

NSString *rowCountString=[NSString stringWithFormat:@"%d",[yourArray count]]; //or dictionary

//if this is for osx 64 bit use %ld instead of %d

然后在标签中显示字符串。

yourLabel.text = rowCountString; //UILabel ios

[yourLabel setStringValue:rowCountString];//NSTextField as label osx
