來自UIButton的自定義UIBarButtonItem的標題不顯示

Question

我從UIButton自定義了UIBarButtonItem。自定義欄按鈕是可見的，動作有效，大小正確，並且可以看到背景色;然而手動設置的標題不能被看到。也許背景是放置在文字上？我不確定，幫忙？

在viewDidLoad：

UIButton *resetButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
resetButton.frame = CGRectMake(0, 0, 65, 30); 
[resetButton addTarget:self action:@selector(speakPhrase:) forControlEvents:UIControlEventTouchUpInside]; 
resetButton.titleLabel.font = [UIFont fontWithName:@"ProximaNova-Bold" size:19]; 
resetButton.titleLabel.text = @"RESET"; 
resetButton.titleLabel.textColor = [UIColor whiteColor]; 
resetButton.backgroundColor = [UIColor redColor]; 
resetButton.showsTouchWhenHighlighted = YES; 

UIBarButtonItem *resetBarBTN = [[UIBarButtonItem alloc] initWithCustomView:resetButton]; 

self.navigationItem.rightBarButtonItem = resetBarBTN; 

Answer 1

你應該設置標題使用setTitle:forState:特定控制狀態的按鈕，下面

UIButton *resetButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
resetButton.frame = CGRectMake(0, 0, 65, 30); 
[resetButton addTarget:self action:@selector(speakPhrase:) forControlEvents:UIControlEventTouchUpInside]; 
resetButton.titleLabel.font = [UIFont fontWithName:@"ProximaNova-Bold" size:19]; 

[resetButton setTitle:@"RESET" forState:UIControlStateNormal]; //change this line in your code 

resetButton.titleLabel.textColor = [UIColor whiteColor]; 
resetButton.backgroundColor = [UIColor redColor]; 
resetButton.showsTouchWhenHighlighted = YES; 

UIBarButtonItem *resetBarBTN = [[UIBarButtonItem alloc] initWithCustomView:resetButton]; 

self.navigationItem.rightBarButtonItem = resetBarBTN; 

Answer 2

使用的setTitle：forState設置按鈕標題。例如

[resetButton setTitle:@"text" forState:UIControlStateNormal]
