stringWithFormat produces string with gibberish characters
提问by TonyNeallon
When debugging the following code
调试以下代码时
NSString *var1 = @"blaa";
NSString *var2 = @"blaaaaa";
NSString* script = [NSString stringWithFormat:@"Set_Variable( %s, %s )",var1,var2];
the %splaceholders in script are replaced with funny gibberish characters.
Can you see any errors in the code?
%s脚本中的占位符被替换为有趣的胡言乱语字符。你能看到代码中的任何错误吗？
回答by Jesús A. álvarez
%s is the format specifier for a C string, char*
%s 是 C 字符串的格式说明符，char*
For objective-c objects (such as NSString) you should use %@
对于objective-c 对象（例如NSString），您应该使用%@
