如何修復tableview底部的按鈕？

Question

在我的應用程序中，我想修復表格視圖底部的按鈕。

這是我的初始屏幕，

在頁腳部分創建的按鈕

-(UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
if(tableView == educateTbl) 
{
    float footerWidth = 150.0f;
    float padding = 10.0f;
    UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, footerWidth, 50.0)];
    footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

    UIButton *addEdu = [[UIButton alloc]initWithFrame:CGRectMake(padding, 0, footerWidth - 2.0f * padding, 44.0f)];
    addEdu.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
    addEdu.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

    [addEdu setTitle:@"Add Education" forState:UIControlStateNormal];
    [addEdu addTarget:self action:@selector(addEducation:) forControlEvents:UIControlEventTouchUpInside];
    [addEdu setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    addEdu.frame=CGRectMake(0, 0, 200, 30); 
    [footerView addSubview:addEdu];
    return footerView;
}
return nil;
}

之后我就變成這樣了

我該如何解決？

Answer 1

你為什么不做這樣的事情？

-(void)setTableFooter
{
   float footerWidth = 150.0f;
   float padding = 10.0f;
   UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, footerWidth, 50.0)];
   footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

   UIButton *addEdu = [[UIButton alloc]initWithFrame:CGRectMake(padding, 0, footerWidth - 2.0f * padding, 44.0f)];
   addEdu.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
   addEdu.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

   [addEdu setTitle:@"Add Education" forState:UIControlStateNormal];
   [addEdu addTarget:self action:@selector(addEducation:) forControlEvents:UIControlEventTouchUpInside];
   [addEdu setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
addEdu.frame=CGRectMake(0, 0, 200, 30); 
   [footerView addSubview:addEdu];

   tableView.tableFooterView = footerView;

}

並在初始化表后調用它

Answer 2

-(void)CreateCustomFooter
{
   float footerWidth = 150.0f;
   float padding = 10.0f;
   UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, footerWidth, 50.0)];
   footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth;

   UIButton *addEdu = [[UIButton alloc]initWithFrame:CGRectMake(padding, 0, footerWidth - 2.0f * padding, 44.0f)];
   addEdu.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
   addEdu.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

   [addEdu setTitle:@"Add Education" forState:UIControlStateNormal];
   [addEdu addTarget:self action:@selector(addEducation:) forControlEvents:UIControlEventTouchUpInside];
   [addEdu setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
addEdu.frame=CGRectMake(0, 0, 200, 30); 
   [footerView addSubview:addEdu];

   tableView.tableFooterView = footerView;

}

將上述方法放在 viewDidLoad() 方法中並在初始化 tableview 之后

如果您想使用 tableview 滾動部分頁腳/頁眉，則需要使用分組樣式的 table view。

[[UITableView alloc]initWithFrame:CGRectZero style:UITableViewStyleGrouped]

分組樣式表視圖將具有默認的 backgroundColor 和節頁眉/頁腳高度。 您需要明確設置這些值。

如果只有一節，最好使用tableFooterView而不是節頁腳視圖

Answer 4

雖然滾動該按鈕可見意味着，UITableview 單元格是可重用的，以便該按鈕可用，您必須做的事情意味着。

1.在 UITableView 中取行數，

然后在 indexpath 行的單元格內：

Total number of row ==indexpath.row
{
   //inside this button.hidden=no;
}
else
{
   //button.hidden=yes;
}
