發送'NSString *'錯誤的整數轉換指針不兼容指針

Question

/Users/..../Desktop/apps/..../..../TableViewController.m:147:69：指向整數轉換髮送的不兼容指針「的NSString *」到類型的參數「NSUInteger」（又名「無符號整型」）

這是代碼

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

在最後一行中鍵入objectAtIndex:@"end"而不是objectForKey:@"end"。
