1、第一种方式给Button加上tag值
这里分为两种：一种是直接在原生的UITableViewCell上添加UIButton按钮，然后给UIButton设置tag值，然后在控制器里的方法里通过取数据，做界面跳转等。还是举个例子吧，省的回忆半天。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static
NSString *identifier = @
"Cell"
;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseIdentifier];
if
(cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
User *user = _users[indexPath.row];
cell.user = user;
//拍照button
UIButton *photographButton = [UIButton buttonWithType:UIButtonTypeCustom];
photographButton.frame = CGRectMake(221 , 10, 100, 44);
[photographButton setImage:[UIImage imageNamed:@
"camera.png"
] forState:UIControlStateNormal];
[photographButton addTarget:self action:@selector(photographButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
photographButton.tag = indexPath.row;
[cell.contentView addSubview:photographButton];
return
cell;
}
|
然后在点击事件中取数据，加信息

- (
void
)photographButtonClicked:(UIButton *)sender{
User *user = _users[sender.tag];
PhotoPickerController *photoPicker = [[PhotoPickerController alloc] init];
photoPicker.user = user;
[self.navigationController pushViewController:photoPicker animated:YES];
}

以上两个方法都是在同一个控制器中。另外一种，自定义了UITableViewCell，那么就在UITableViewCell里添加一个代理方法。

#import <UIKit/UIKit.h>
@protocol TermCellDelegate <NSObject>
- (
void
)choseTerm:(UIButton *)button;
@end
@interface TermCell : UITableViewCell
@property (retain, nonatomic) IBOutlet UIButton *checkButton;
@property (retain, nonatomic) IBOutlet UILabel *termLabel;
@property (assign, nonatomic)
BOOL
isChecked;
@property (assign, nonatomic) id<TermCellDelegate> delegate;
- (IBAction)checkAction:(UIButton *)sender;
@end
#import "TermCell.h"
@implementation TermCell
- (
void
)awakeFromNib
{
// Initialization code
}
- (
void
)setSelected:(
BOOL
)selected animated:(
BOOL
)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (
void
)layoutSubviews
{
[super layoutSubviews];
if
(_isChecked) {
[_checkButton setBackgroundImage:[UIImage imageNamed:@
"task_state_checked"
] forState:UIControlStateNormal];
}
else
{
[_checkButton setBackgroundImage:[UIImage imageNamed:@
"task_state_unchecked"
] forState:UIControlStateNormal];
}
}
- (
void
)dealloc {
[_checkButton release];
[_termLabel release];
[super dealloc];
}
- (IBAction)checkAction:(UIButton *)sender {
if
([_delegate respondsToSelector:@selector(choseTerm:)]) {
sender.tag = self.tag;
[_delegate choseTerm:sender];
}
}
@end
|
然后再控制器中实现Cell的代理方法即可

#pragma mark - TermCellDelegate
- (
void
)choseTerm:(UIButton *)button
{
_clickIndex = button.tag;
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@
"确定修改学期吗？"
message:nil delegate:self cancelButtonTitle:@
"取消"
otherButtonTitles:@
"确定"
, nil nil];
[alertView show];
}

当然，这里也可以做界面跳转，取数据依然用button的tag值。第二种，是直接在自定义的Cell里面跳转，这种耦合性比较强。思路先是找到button的父控制器，然后做界面跳转或者其他操作。有这样一个工具方法

(UIViewController *)next;
}
next = [next nextResponder];
}
while
(next != nil);
return
nil;
}
