指向整数转换的指针不兼容，发送'NSString *'错误

Question

/ Users /..../ Desktop / apps /.... / _ / TableViewController.m:147：69：指向整数转换的指针不兼容将'NSString *'发送到'NSUInteger'类型的参数（又名'unsigned int'）

这是代码

    NSString * vak = [[jsonArray objectAtIndex:i] objectForKey:@"lesson"];
    NSString * Lraar = [[jsonArray objectAtIndex:i] objectForKey:@"teacher"];
    NSString * begin = [[jsonArray objectAtIndex:i] objectForKey:@"start"];
    NSString * lok = [[jsonArray objectAtIndex:i] objectForKey:@"room"];
    NSString * end = [[jsonArray objectAtIndex:i] objectAtIndex:@"end"];

Answer 1

在最后一行中，您输入了objectAtIndex:@"end"而不是objectForKey:@"end"。
