ios 中有这个黑暗巫术阻止我的按钮被点击。如果我不向 uitableviewcell 添加按钮，然后单击该按钮，则会触发该事件。但是如果按钮在uitableviewcell中，它不会被触发，似乎表格我已经准备好了示例代码，如果你们可以帮助我，请在xcode中创建一个简单的单视图应用程序，然后粘贴以下代码
//GRDViewController.h
#import <UIKit/UIKit.h>
@interface GRDViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>
@property (nonatomic, strong) UIView* container;
@property (nonatomic, strong) UIButton* button;
@property (nonatomic, strong) UITableView* tableView;
@property (nonatomic, strong) NSArray* arr;
@end
//GRDViewController.m
#import "GRDViewController.h"
@implementation GRDViewController
@synthesize button, container, arr, tableView;
- (void)_btnTapped {
NSLog(@"TAPPED");
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.button = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
[self.button addTarget:self action:@selector(_btnTapped) forControlEvents:UIControlEventTouchUpInside];
[self.button setTitle:@"CLICK ME" forState:UIControlStateNormal];
self.arr = [[NSArray alloc] initWithObjects:@"123", @"456", @"678", nil];
self.container = [[UIView alloc]initWithFrame:self.button.frame];
[self.container addSubview:self.button];
[self.view addSubview:self.container];
//[self.view addSubview:self.button];
self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 100, 400, 400)];
self.tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.delegate = self;
self.tableView.dataSource = self;
[self.view addSubview:self.tableView];
self.tableView.backgroundColor = [UIColor redColor];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"coolcell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
//cell.accessoryType = UITableViewCellAccessoryNone;
UIButton * btn = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 50, 50)];
[btn addTarget:self action:@selector(_btnTapped) forControlEvents:UIControlStateNormal];
[btn setTitle:[self.arr objectAtIndex:[indexPath row]] forState:UIControlStateNormal];
[cell.contentView addSubview:btn];
}
return cell;
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {
return [self.arr count];
}
@end
请帮助我觉得这种情况在 ios 中应该很常见，但没有人对此有解决方案？？？
编辑：当单击按钮时，它会在 xcode 控制台中打印 NSLOG msg...所以请确保...您正在查看那里的结果...
