如何將圖像和標籤添加到UINavigationBar作爲標題？

Question

目前我只知道如何把一個字符串作爲一個標題：

[self setTitle:@"iOS CONTROL"]; 

或在同一時間

與

self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"icon.png"]]; 

但不能同時圖像有一個方案？謝謝

Answer 1

您可以創建一個UIView並根據需要添加儘可能多的子視圖。例如：

UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 100.0, 40.0)]; 
titleView.backgroundColor = [UIColor clearColor]; 

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"icon.png"]]; 

UILabel *titleLabel = [[UILabel alloc] init]; 
titleLabel.backgroundColor = [UIColor clearColor]; 
titleLabel.textColor = [UIColor redColor]; 
titleLabel.text = @"My Title Label"; 
[titleLabel sizeToFit]; 

... 

// Set the frames for imageView and titleLabel to whatever you need them to be 

... 

[titleView addSubview:imageView]; 
[titleView addSubview:titleLabel]; 

self.navigationItem.titleView = titleView; 

Answer 2

創建一個新的UIView，添加UIImage和UILabel作爲子視圖你想要的方式，並添加UIView使用self.navigationItem.titleView。
