我有一个 UIViewController 类,带有一个 tableView。在viewDidLoad中:
UIBarButtonItem *editIcon = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem: UIBarButtonSystemItemEdit
target:self
action:@selector(toggleEditMode)] autorelease];
在方法“toggleEditMode”中:
-(void)toggleEditMode{
if(self.theTable.editing) {
[theTable setEditing:NO animated:YES];
[self.navigationItem.rightBarButtonItem setStyle:UIBarButtonItemStylePlain];
}
else if ([callsArray count]!=0){
[theTable setEditing:YES animated:YES];
[self.navigationItem.rightBarButtonItem setStyle:UIBarButtonItemStyleDone];
}
}
问题是“编辑”按钮不会更改为“完成”。少了什么东西?我已经声明了所有方法:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
谢谢

最佳答案
为什么不直接使用UIViewController的-editButtonItem
?并重写 -setEditing:animated:
方法。
// Assign the system's edit button,
// it will change style when different edit status.
self.navigationItem.rightBarButtonItem = self.editButtonItem;
// The editButtonItem will invoke this method.
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
if (editing) {
// Execute tasks for editing status
} else {
// Execute tasks for non-editing status.
}
}
关于iphone - UITableView 处于编辑模式 - 'Edit' 按钮不会更改状态,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/5365074/
