Question

我制作了一款iOS应用。一个视图具有Web视图和导航栏。导航栏出了问题。在iPhone 6s上，导航栏中的标题是“这是我的应用程序！”。但在iPhone 5s上，导航栏中的标题是“这是我的......”。这是因为iPhone 5s屏幕不像iPhone 6s加屏幕那么宽，所以我的标题太长了。

是否有可能自动缩小文本或为iPhone 5s（和其他设备）设置自己的字体大小或其他标题？

我几乎整天用Google搜索，但找不到任何有用的提示。有人有想法吗？请帮帮我！

以下是iPhone 5s的屏幕截图：link

试试这个：

label.adjustsLetterSpacingToFitWidth = true

你也可以试试这个：

#include <stdio.h>
#include <unistd.h>
#include<sys/types.h>
#include<sys/wait.h>

#define MAX_LINE 80

int main(void)
{
    char *args[MAX_LINE/2+1];
    int background= 0;//integer that acts a boolean for if & appears
    int should_run = 1;
    int status;

        while(should_run)//Just to keep the interface going until the user chooses to stop
        {
            printf("osh>");//prompt
            fflush(stdout);

            int i = 0;
            while(getchar() != '\n')//Use scanf until a new line is found
            {
                scanf("%s", &args[i]);

                if(strcmp(&args[i], "exit") == 0)//temporary exit protocal
                {
                    printf("Exiting now...");
                    return 0;
                }


                if(strcmp(&args[i], "&") == 0)//If we find a & in our input then we changed background to 1 or true
                    background = 1;
                printf("Args[%i] = %s\n", i, &args[i]);//Tester
                i++;
            }


            printf("Background = %i\n",background);//Test
            pid_t pid= fork();// Create new child process
            printf("process %i created\n", pid);//Test



            if(pid < 0)//fork() failed
            {
                printf("Fork Failed.\n");
                return 1;
            }

            else if(pid == 0)//Child process id
            {
                printf("Child process started %s command\n", &args[0]);
                if(execvp(args[0], args) < 0)//change the current child process to execute the input given by the user 
                                //with args[0] being the command and args being the parameters(ls -l is an example).
                {
                    printf("Command failed\n");
                }
                return 0;
            }

            else//Parent Process
            {
                if(background == 1)//If the user typed in a & then the parent will wait for a change in state from the child, if there is no &
                            //then we will just finish the parent process
                {
                    printf("Parent process waiting on child\n");
                    wait(NULL);
                }
            }

        }

    return 0;

Answer 2

您可以使用以下示例。

NSDictionary *size = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:17.0], NSFontAttributeName, nil];

UINavigationController* navigationController = [self navigationController];
[navigationController.navigationBar setTitleTextAttributes:size];

Answer 3

试试这个

UILabel *lbl=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, YOUR_WIDH, YOUR_HEIGHT)];
lbl.textAlignment=NSTextAlignmentCenter;
lbl.backgroundColor=[UIColor clearColor];
lbl.font=[UIFont fontWithName:@"FONT_NAME" size:FONT_SIZE];
lbl.textColor=[UIColor whiteColor];
lbl.text=@"YOUR_TITLE";
self.navigationItem.titleView=lbl;

希望这有帮助。

导航栏中的标题在较小的屏幕上太长;设置不同屏幕尺寸的字体大小？
