iPhone - XCode未声明的标识符

Question

我正在创建表视图，并且不断收到未声明的标识符错误。我在源代码中评论了这些错误。

- (void)loadTableView1 { 
UITableView *tableView1 = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 454) 
                 style:UITableViewStyleGrouped]; 
[tableView1 setDataSource:self]; 
[tableView1 setDelegate:self];

[self addSubview:tableView1]; 
[tableView1 release]; 
} 

#pragma mark - 
#pragma mark TableView Delegates 

- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section { 
NSDictionary *sectionContainer = [tableView1CellData objectAtIndex:section]; 
NSMutableArray *cells = [sectionContainer objectForKey:tableView1"Cells"]; //use of undeclared identifier 'tableView1' 
return [cells count]; 
} 

编辑： 下面是从日志中的错误：

错误：使用未声明的标识符的 'tableView1'

NSMutableArray *cells = [sectionContainer objectForKey:tableView1"Cells"]; 

Answer 1

这个是什么意思：

[sectionContainer objectForKey:tableView1"Cells"]; 

或者您可以使用constent string，string variable，或者如果必须使用两个字符串进行字符串比使用NSString方法。 你可以使用这样的：

NSMutableArray *cells = [sectionContainer objectForKey:@"Cells"]; 

Answer 2

而是这个

NSMutableArray *cells = [sectionContainer objectForKey:tableView1"Cells"]; 

使用此

NSMutableArray *cells = [sectionContainer objectForKey:@"Cells"];
