Question

有人知道如何检查分段控件触发了什么事件吗？我正在创建两个包含分段控件的单元格。在segmentedControlIndexChanged方法中，我想知道哪个分段控件已触发事件。我使用标签，但它不起作用。我是新来的。我很感激你的帮助。

单元格的代码，包含分段控件：

 cellParinti = [[Cell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
cellParinti.textLabel.text = @"Parinti";
cellParinti.label.text = dog?dog.parinti:@"";
cellParinti.segmentedControl.selectedSegmentIndex = [dog.parinti isEqualToString:@"da"] ? 0 : 1;
cellParinti.segmentedControl.tag = 1;
[cellParinti.segmentedControl addTarget:self action:@selector(segmentedControlIndexChanged:) forControlEvents:UIControlEventValueChanged];
[cellParinti addSubview:cellParinti.textLabel];
[cellParinti addSubview:cellParinti.label];
[cellParinti addSubview:cellParinti.segmentedControl];


cellPedigree = [[Cell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
cellPedigree.textLabel.text = @"Pedigree";
cellPedigree.label.text = dog?dog.pedigree:@"";
cellParinti.segmentedControl.tag = 2;
cellPedigree.segmentedControl.selectedSegmentIndex = [dog.pedigree isEqualToString:@"da"] ? 0 : 1;
[cellPedigree.segmentedControl addTarget:self action:@selector(segmentedControlIndexChanged:) forControlEvents:UIControlEventValueChanged];

[cellPedigree addSubview:cellPedigree.textLabel];
[cellPedigree addSubview:cellPedigree.label];
[cellPedigree addSubview:cellPedigree.segmentedControl];

该方法的代码已被触发：

-(void) segmentedControlIndexChanged:(id)sender{
NSIndexPath *indexPath;

UISegmentedControl * sg1 = (UISegmentedControl *)sender;

// reload data based on the new index
if (sg1.tag == 1){
cellParinti.label.text = sg1.selectedSegmentIndex == 0 ? @"da" : @"nu";
dog.parinti = sg1.selectedSegmentIndex == 0 ? @"da" : @"nu";
}
else {
    cellPedigree.label.text = sg1.selectedSegmentIndex == 0 ? @"da" : @"nu";
    dog.pedigree = sg1.selectedSegmentIndex == 0 ? @"da" : @"nu";
}

}

你有

cellParinti.segmentedControl.tag = 2;

我认为这应该是

cellPedigree.segmentedControl.tag = 2;

这是代码中的拼写错误，导致您无法获取正确的代码。

如何区分两个分段控件？
