我們如何在自定義單元中添加按鈕？

Question

我在一個應用程序中工作，需要通過customcell在單元格中添加按鈕。 任何人都可以幫助我嗎？ 在此先感謝

在Customcell中添加一個按鈕，請使用以下代碼。 首先，您添加具有UITableViewCell的子類的新文件，然後 Customcell.h文件 @interface CustomCell：UITableViewCell { {UIButton * customButton; } @property（nonatomic，retain）UIButton * customButton;

  Customcell.m 
@implementation CustomCell; 
      @synthesize customButton; 

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier 
{ 
    if ((self = [super initWithStyle:style reuseIdentifier:reuseIdentifier])) 
    { 
      customButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
     [customButton setImage:[UIImage imageNamed:@"phonecall.png"] forState:UIControlStateNormal]; 
     } 
     return self; 
} 

// set layout in subview 
- (void)layoutSubviews 
{ 

    [super layoutSubviews]; 

    CGRect contentRect = self.contentView.bounds; 

    CGFloat boundsX = contentRect.origin.x; 

    CGFloat boundY = contentRect.origin.y; 

    CGRect frame1; 

     frame1 = CGRectMake(boundsX+10, boundY+58, 19, 18); 
    customButton.frame = frame1; 

} 

#import "CustomCell.h" 
In cellForRowAtIndexPath method 

// Customize the number of cells in the table view. 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 

    CustomCell *cell= [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; 

    if (cell == nil) 
    { 
     cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; 
    } 

    [cell.customButton addTarget:self action:@selector(callAction:) forControlEvents:UIControlEventTouchUpInside]; 
return cell; 
}
