如何讓test.m文件中的UIButton的狀態值

Question

在.m文件我有一個像

-(void) textdata 
{ 
    long i = search.text.length; 
    if (i > 0) { 
     searchButton.enabled = YES;   
    } 
    else 
    { 
     searchButton.enabled = NO; 
    } 
    [self buttonstate]; 
} 

-(int) buttonstate 
{ 
    if ([searchButton isEnabled]) { 
     j = 1; 
    } 
    else 
     j = 0; 

    NSLog(@" j value is %d",j); 
    return j; 
} 

- (void) textFieldDidChange 
{ 
    [self textdata]; 
    NSLog(@"test data is %@",search.text); 
} 

方法和在tests.m文件我有測試樣

-(void) testwithoutData 
{ 
    myapiViewController *apiViw = [[myapiViewController alloc]init]; 
    [apiViw textdata]; 

    int kn = [apiViw buttonstate]; 
    NSLog(@"the value is %ld",(long)kn); 
}

你要做的alloc init，因爲由於這個實例變量變爲零。試試這個 -

在ViewController.m -

-(int) buttonstate { 

long i = self.searchTxt.text.length; 

if (i > 0) { 
    self.searchBtn.enabled = YES; 
} 
else 
{ 
    self.searchBtn.enabled = NO; 
} 

if ([self.searchBtn isEnabled]) { 
    j = 1; 
} 
else  
j = 0; 


NSLog(@" j value is %d",j); 

return j; 
} 

在ViewControllerTests.m -

- (void)testExample { 
    // This is an example of a functional test case. 
    XCTAssert(YES, @"Pass"); 
    self.vcToTest.searchTxt = [[UITextField alloc] init]; 
    self.vcToTest.searchBtn = [[UIButton alloc] init]; 

    self.vcToTest.searchTxt.text = @"test"; 
    int kn = [self.vcToTest buttonstate];  
    NSLog(@"the value is %ld",(long)kn); 
}
