1. 增加一個背景圖
2. 在mainViewController.m加入UITextView的背景設定，並加上一個消除輸入鍵盤的機制在觸及按鍵時。
#import "mainViewController.h"
@interface mainViewController ()
@end
@implementation mainViewController
@synthesize textEdit;
@synthesize fileName;
@synthesize filePath;
@synthesize data;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
fileName = @"測試檔";
filePath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"txt"];
textEdit.backgroundColor = [UIColor clearColor];
UIImageView *a1 = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 500, 300)];
[a1 setImage:[UIImage imageNamed:@"TaiwanMap.jpg"]];
a1.alpha = 0.1f;
[self.view addSubview:a1];
[self.view sendSubviewToBack:a1];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)readFile:(id)sender {
if (filePath) {
NSString *contentOfFile = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
textEdit.text = contentOfFile;
}
[textEdit resignFirstResponder];
}
- (IBAction)clearWindow:(id)sender {
textEdit.text = @"";
[textEdit resignFirstResponder];
}
- (IBAction)saveFile:(id)sender {
data = textEdit.text;
if (filePath) {
[data writeToFile:filePath atomically:NO encoding:NSUTF8StringEncoding error:nil];
}
[textEdit resignFirstResponder];
}
@end
4. 結果
