我想要两个单元格登录(用户名和密码)。所以我运行应用程序,一切正常但是当我点击UITextField“playerTextField”时,程序收到了这个信号:“EXC_BAD_ACCESS”。 :(
你知道为什么吗?我已经尝试过并阅读了很多不同的方法,就像这一个我接近它的方式。我的代码:
如果按下Next / Done按钮,键盘将消失。
- (BOOL) textFieldShouldReturn:(UITextField *)textField{
[textField resignFirstResponder];
return YES;
}
我的UITextFields在单元格内。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *kCellIdentifier = @"kCellIdentifier";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:kCellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryNone;
if ([indexPath section] == 0) {
playerTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
playerTextField.adjustsFontSizeToFitWidth = YES;
playerTextField.textColor = [UIColor blackColor];
if ([indexPath row] == 0) {
playerTextField.placeholder = @"ejemplo@gmail.com";
playerTextField.keyboardType = UIKeyboardTypeEmailAddress;
playerTextField.returnKeyType = UIReturnKeyNext;
playerTextField.delegate = self;
}
else {
playerTextField.placeholder = @"Requerida";
playerTextField.keyboardType = UIKeyboardTypeDefault;
playerTextField.returnKeyType = UIReturnKeyDone;
playerTextField.secureTextEntry = YES;
playerTextField.delegate = self;
}
playerTextField.backgroundColor = [UIColor whiteColor];
playerTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
playerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
playerTextField.textAlignment = UITextAlignmentLeft;
playerTextField.tag = 0;
playerTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
[playerTextField setEnabled: YES];
//cell.textLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:20.0];
cell.textLabel.font = [UIFont fontWithName:@"Futura" size:16.0];
cell.textLabel.textColor = [UIColor darkGrayColor];
cell.textLabel.shadowOffset = CGSizeMake(0.5, 0.5);
cell.textLabel.shadowColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:10];
[cell.contentView addSubview:playerTextField];
//[playerTextField release];
}
}
if ([indexPath section] == 0) { // Email & Password Section
if ([indexPath row] == 0) { // Email
cell.textLabel.text = @"Email";
}
else {
cell.textLabel.text = @"Contraseña";
}
}
else { // Login button section
cell.textLabel.text = @"Log in";
}
return cell;
}
答案 0 :(得分:0)
我在可见代码中看不到会导致此类问题的任何内容。
仪器应该可以帮助您找出问题发生的位置。有一种叫做“Zombies”的乐器就是为了这个目的而设计的。当您到达EXC_BAD_ACCESS时,它将显示代码中保留和释放该对象的每个位置。从那里你可以找出你释放太多次的地方(或者可能忘了保留它)。
