我不能讓圖像和按鈕四角變圓

Question

我正在創建UITableViewController的單元格。 其中之一，包含一個小圖像。我嘗試以下，以使其邊角圓潤：

profileImage.layer.cornerRadius = 8; 
profileImage.clipsToBounds = YES; 

在另一個細胞的原型，我試圖讓圓潤的按鈕的角落：

chooseImageFromRoll.clipsToBounds = YES; 
    chooseImageFromRoll.layer.cornerRadius = 8; 

在這兩種情況下，我包括

#import <QuartzCore/QuartzCore.h> 

該按鈕和角落必須圓角的圖像是擁有它們的UITableViewController的屬性：

#import <UIKit/UIKit.h> 

@interface profileRegistrationCellVC : UITableViewCell 
@property (weak, nonatomic) IBOutlet UIImageView *profileImage; 
@property (weak, nonatomic) IBOutlet UIButton *chooseImageFromRoll; 
@property (weak, nonatomic) IBOutlet UIButton *shootImage; 

@end 

在相對的.m類：

#import "profileRegistrationCellVC.h" 
#import <QuartzCore/QuartzCore.h> 

@implementation profileRegistrationCellVC 
@synthesize profileImage; 
@synthesize chooseImageFromRoll; 
@synthesize shootImage; 

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier 
{ 
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; 
    if (self) { 
     // Initialization code 
     chooseImageFromRoll.clipsToBounds = YES; 
     chooseImageFromRoll.layer.cornerRadius = 8; 
     shootImage.layer.cornerRadius = 8; 

     profileImage.layer.cornerRadius = 8; 
     profileImage.clipsToBounds = YES; 

     profileImage.layer.borderColor = [UIColor whiteColor].CGColor; 
     profileImage.layer.borderWidth = 20.0; 

     [self addSubview:profileImage]; 
     [self addSubview:chooseImageFromRoll]; 
     [self addSubview:shootImage]; 


    } 
    return self; 
} 

- (void)setSelected:(BOOL)selected animated:(BOOL)animated 
{ 
    [super setSelected:selected animated:animated]; 

    // Configure the view for the selected state 
} 

@end 

這裏是我的函數的cellForRowAtIndexPath的代碼，在我的UITableViewController：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 

    if (indexPath.section == 0) { 
     static NSString *CellIdentifier = @"profileRegistrationCell"; 

     profileRegistrationCellVC *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
     if (cell == nil) { 
      cell = [[profileRegistrationCellVC alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
     } 

     //cell.profileImage.image.layer.masksToBounds = YES; 
     //cell.profileImage.layer.cornerRadius = 5.0; 

     return cell; 

    } 

    else if (indexPath.section == 1) { 
     static NSString *CellIdentifier = @"regularRegistrationCell"; 

     regularRegistrationCellVC *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
     if (cell == nil) { 
      cell = [[regularRegistrationCellVC alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
     } 

     cell.regularFieldName.text = [_registrationItems objectAtIndex:indexPath.row]; 

     if ([[_registrationItems objectAtIndex:indexPath.row] isEqualToString:@"Email*"]) 
      cell.regularTextField.keyboardType = UIKeyboardTypeEmailAddress; 

     if ([[_registrationItems objectAtIndex:indexPath.row] isEqualToString:@"Età"]) { 
      cell.regularTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; 
     } 

     return cell; 

    } 

    else{ 
     static NSString *CellIdentifier = @"orientationRegistrationCell"; 

     orientationRegistrationCellVC *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
     if (cell == nil) { 
      cell = [[orientationRegistrationCellVC alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
     } 

     cell.fieldLabel.text = [_registrationItems objectAtIndex:[_registrationItems count]-1]; 
     cell.orientationLabel.text = @"Non specificato"; 
     return cell; 

    } 
} 

但在任何情況下，我設法讓圓角。你能說出我錯在哪裏嗎？

謝謝

上面的代碼片段都是正確的，沒有問題。我的假設是，你的問題在於創建包含圖像的按鈕。下面的代碼將創建一個按鈕，並將其四捨五入，我也添加了邊框以防萬一你想添加。你也可以插入你在那裏的圖片。我已經添加了這個代碼將爲您的再次創建的圖像。希望它能幫助你。

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    btn.frame = CGRectMake(100, 100, 100,50); 
    [btn setTitle:@"Hello" forState:UIControlStateNormal]; 
    [btn setBackgroundColor:[UIColor colorWithRed:128.0/255.0f green:0.0/255.0f blue:0.0/255.0f alpha:0.7]]; 
    btn.frame = CGRectMake(100.0, 100.0, 120.0, 50.0);//width and height should be same value 
    btn.clipsToBounds = YES; 

    btn.layer.cornerRadius = 20;//half of the width 
    btn.layer.borderColor=[UIColor redColor].CGColor; 
    btn.layer.borderWidth=2.0f; 

    [self.view addSubview:btn]; 

下面是與上面的代碼相關的按鈕的圖像

編輯：

做圓角的另一種方法是使用方法masksToBounds這裏就是它在通用單元格中的一個例子，從模板開始。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath]; 

NSDate *object = _objects[indexPath.row]; 
cell.textLabel.text = [object description]; 
cell.imageView.image = [UIImage imageNamed:@"acolon.png"]; 
cell.imageView.layer.masksToBounds = YES; 
cell.imageView.layer.cornerRadius = 5.0; 
return cell; 
} 

這裏是結果的屏幕截圖：

我知道你使用自定義的電池，因此實現在cellForRowAtImdexPath的maskToBount或任何你正在填充tableview其定製細胞。
