__bridge的用法

__bridge作为OC与C语言之间的桥接符号使用,

简单的用法:

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
    
    char *str = "str";
    method5(str);
    
    
//    NSString *name = @"name";
//    method5((__bridge void*)(name));
}


void method5(void * str){
//    NSString *name = (__bridge NSString *)(str);
//    NSLog(@"method5:%@",name);
    NSLog(@"C-Str : %s",str);
}
