问题描述

我创建了一个名为CheckBox的自定义类，该类可在触摸时更改其图像，从而提供复选框效果。但是，当我单击tableView中的一个复选框时，也会选择单独行上的其他复选框。请您告诉我代码的问题：
复选框
- (void)checkImages {
NSUInteger tag = [self tag];
BOOL val = [[NSUserDefaults standardUserDefaults] boolForKey:[Nsstring stringWithFormat:@\"%i\",tag]];
if (val == YES) {
[self setimage:[UIImage imageNamed:@\"checkBox-pressed.png\"] forState:UIControlStatenormal];
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:[Nsstring stringWithFormat:@\"%i\",tag]];
}
else if (val == NO) {
[self setimage:[UIImage imageNamed:@\"checkBox.png\"] forState:UIControlStatenormal];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:[Nsstring stringWithFormat:@\"%i\",tag]];
}
[[NSUserDefaults standardUserDefaults] synchronize];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
if ([[[[event alltouches] anyObject] view] tag] == [self tag]) {
[self checkImages];
}
}
- (void)viewDidLoad
{
//This will set a solid background color
self.tableView.backgroundColor = [UIColor blackColor];
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
if (_checkBoxArray == nil) {
[self setItemArray:[[NSMutableArray alloc] init]];
}
if (_cellTextArray == nil) {
[self setCellTextArray:[[NSMutableArray alloc] init]];
}
if (![[NSUserDefaults standardUserDefaults] boolForKey:kFL]) {
NSMutableArray *custArr = [[NSMutableArray alloc] init];
for (int i = 0; i < [_checkBoxArray count]; i ++) {
CheckBox *c = (CheckBox *)[_checkBoxArray objectAtIndex:i];
[c setimage:[UIImage imageNamed:@\"checkBox.png\"] forState:UIControlStatenormal];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:[Nsstring stringWithFormat:@\"%i\",[c tag]]];
[custArr addobject:c];
}
[_checkBoxArray release];
[_checkBoxArray setArray:custArr];
[custArr release];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:kFL];

}
解决方法
您正在使用
tableView dequeueReusableCellWithIdentifier:CellIdentifier]
tableView:(UITableView *)tableView cellForRowAtIndexPath:
lab.text = [dict objectForKey:@\"textLabel\"];
