如何通过iOS中的参数将UITableView IndexPath传递给UIButton @selector? [英] How to pass UITableView IndexPath to UIButton @selector by parameters in iOS?
问题描述
我在 UITableViewCells
中添加了 UIButton
。我有用户单击按钮时,我们已获得索引路径以使用 NSMutableArray
中的值。我使用下面的方法来获取当前的 IndexPath
,
I have added UIButton
in UITableViewCells
. I have when the user clicks the button we have get the indexpath to use the values from NSMutableArray
. I have used the below to get the current IndexPath
,
[getMeButton addTarget:self action:@selector(resendTheErrorMessage:) forControlEvents:UIControlEventTouchUpInside];
-(void) resendTheErrorMessage:(id)sender
{
NSLog(@"SEnder: %@", sender);
//NSLog(@"Index Path : %@", indexpath);
}
任何人都可以帮我传递当前的indexpath UIButton's
@selector。提前致谢。
Can anyone please help me to pass current indexpath UIButton's
@selector. Thanks in advance.
编辑:
这是我从<$ c $获得的输出c> NSLog()
<UIButton: 0x864d420; frame = (225 31; 95 16); opaque = NO; tag = 105; layer = <CALayer: 0x864d570>>
推荐答案
添加 UIButton
喜欢这个
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setFrame:CGRectMake(10.0, 2.0, 140.0, 40.0)];
[btn setTitle:@"ButtonTitle" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[btn setTag:indexPath.row];
[cell.contentView addSubview:btn];
然后获取其标签号 -
And then get its tag number -
-(void)buttonClicked:(id)sender
{
NSLog(@"tag number is = %d",[sender tag]);
//In this case the tag number of button will be same as your cellIndex.
// You can make your cell from this.
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[sender tag] inSection:0];
UITableViewCell *cell = [tblView cellForRowAtIndexPath:indexPath];
}
注意: 以上当tableView只有1个部分时,解决方案将起作用。如果您的tableView有多个部分,您应该知道您的部分索引或者使用以下方法。
Note: Above solution will work when your tableView has only 1 section. If your tableView has more than one section either you should know your section index or go for below methods.
备选:1
UIView *contentView = (UIView *)[sender superview];
UITableViewCell *cell = (UITableViewCell *)[contentView superview];
NSIndexPath *indexPath = [tblView indexPathForCell:cell];
替代方案:2
CGPoint touchPoint = [sender convertPoint:CGPointZero toView:tblView];
NSIndexPath *indexPath = [tblView indexPathForRowAtPoint:touchPoint];
UITableViewCell *cell = [tblView cellForRowAtIndexPath:indexPath];
