This article will explain in detail how to use stringWithFormat for you. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Common output methods of stringWithFormat:

NSString*height

Height= [NSString stringWithFormat:@ "Yourheightis%dfeet,%dinches.", 5J 11]

NSLog (@ "% @", height)

Output result:

2013-04-1210:30:47.744String [2161 303] Yourheightis5feet,11inches.

How to output multiple characters (take two characters as an example):

NSString*str

NSString * str1= @ "123"

NSString*str2=@ "465"

Str= [NSStringstringWithFormat:@ "% @,% @", str1,str2]

NSLog (@ "% @", str)

Replace the stringWithFormat: method in the NSString class

Give the source code first:

NSString*String (NSString*format,...)

{

Va_listap

Va_start (ap,format)

NSString*body= [[NSStringalloc] initWithFormat:formatarguments:ap]

Va_end (ap)

Returnbody

}
