如何在NSLog中显示NSString

Question

以下将编译,但如果运行它将崩溃.

-(void) testFunc : (NSString *)s{
    NSLog(@"%@", s);
}

这段代码出了什么问题？

我把这个函数称为:

NSString *msg = @"This is a message";
[self performSelector:@selector(testFunc) withObject:msg afterDelay:0];
[msg release];

Answer 1

[self performSelector:@selector(testFunc) withObject:msg afterDelay:0];

应该:

[self performSelector:@selector(testFunc:) withObject:msg afterDelay:0];
