我正在分组的表格视图中制作表格。在这种形式中,我有 UIswitches 和文本字段。但向下滚动后,单元格样式正在发生变化。
这是我的 cellForRowAtIndex
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
static NSString *MyIdentifier = @"GenericCell";
cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
}
NSString *text = nil;
if(indexPath.section == CREDENTIALS_SECTION){
if (indexPath.row == 0) {
NSLog(@"tot hier login");
UITextField *login = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
login.adjustsFontSizeToFitWidth = YES;
login.placeholder = @"example@gmail.com";
login.keyboardType = UIKeyboardTypeEmailAddress;
login.returnKeyType = UIReturnKeyNext;
login.backgroundColor = [UIColor clearColor];
login.tag = 0;
login.delegate = self;
[login setEnabled: YES];
[cell addSubview:login];
}else if (indexPath.row == 1){
NSLog(@"tot hier pass");
UITextField *pass = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
pass.adjustsFontSizeToFitWidth = YES;
pass.placeholder = @"Required";
pass.keyboardType = UIKeyboardTypeDefault;
pass.returnKeyType = UIReturnKeyDone;
pass.secureTextEntry = YES;
pass.backgroundColor = [UIColor clearColor];
pass.tag = 0;
pass.delegate = self;
[cell addSubview:pass];
}
if (indexPath.row == 0) { // Email
text = @"Email";
}
else if(indexPath.row == 1) {
text = @"Password";
}
}else if(indexPath.section == METHODS_SECTION){
UISwitch *toggleSwitch = [[UISwitch alloc]initWithFrame:CGRectMake(220, 10, 100, 30)];
toggleSwitch.tag = indexPath.row;
[toggleSwitch addTarget:self action:@selector(toggleSwitched:) forControlEvents:UIControlEventValueChanged];
[cell addSubview:toggleSwitch];
if (indexPath.row == 0) { // Web
text = @"Web applicatie";
}
else if(indexPath.row == 1) { //Mobile
text = @"Mobiele applicatie";
}
else if(indexPath.row == 2) { //Mail
text = @"E-mail";
}
}else if(indexPath.section == PHONE_SECTION){
UITextField *phoneText = [[UITextField alloc] initWithFrame:CGRectMake(20, 10, 185, 30)];
phoneText.adjustsFontSizeToFitWidth = YES;
phoneText.font = [UIFont fontWithName:@"Arial-BoldMT" size:18];
phoneText.keyboardType = UIKeyboardTypeNumberPad;
phoneText.delegate = self;
phoneText.textColor = [UIColor blackColor];
phoneText.text = _person.phone;
[cell addSubview:phoneText];
}else if(indexPath.section == REMARK_SECTION){
UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(20, 10, 280, 260)];
textView.text = _person.remark;
textView.delegate = self;
textView.font = [UIFont fontWithName:@"Arial" size:15.0];
textView.backgroundColor = [UIColor clearColor];
[cell addSubview:textView];
text = @"";
}else if(indexPath.section == BUTTON_SECTION){
cell.backgroundColor = [UIColor redColor];
text = @"test";
}
cell.textLabel.text = text;
return cell;
}
经过一番搜索,我发现更多人有这个问题。问题在于这段代码。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
static NSString *MyIdentifier = @"GenericCell";
cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] ;
}
NSString *text = nil;
但我没有找到解决方案。希望任何人都可以提供帮助!
亲切的问候!
澄清
好的,所以在这里您可以看到我的表格的屏幕截图。下面我有一个红色的单元格(保存按钮),当我向下滚动时,其他单元格的背景是红色的。有些单元格,文本属性正在发生变化。
