iphone - 无法识别的选择器发送到类 0x51e8'
<p><p>当我尝试将 uitextfeild 值从我的 tableView:didSelectRowAtIndexPath: 方法传递给我的 nsobject 类时，我遇到了这个错误，但是当我单击我为传递 uitextfield 值而编写的 uitableviewcell 时，我收到了下面列出了错误。</p>
<p>//DBAccess.h</p>
<pre><code> @interface DBAccess : NSObject {
NSString *receiveCodeText;
}
@property (nonatomic, retain) IBOutlet NSString *receiveCodeText;
- (NSMutableArray *) getAllMakes;
- (void) setPassCode:(NSString *)theCode;
</code></pre>
<p>//DBAccess.m</p>
<pre><code>//...
//Need to set my string here..
- (void)setPassCode:(NSString *)theCode{
receiveCodeText = theCode;
}
//...
- (NSMutableArray *)getAllMakes{
//...
const char *value = ; //reciveCodeText is set in RootViewController and passed to value here
;
sqlite3_bind_text(statement, 1, value, -1, SQLITE_TRANSIENT);
//....
}
</code></pre>
<p>//viewController.m</p>
<pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
searchTableViewController *searchTable = [ initWithNibName:@"searchTableViewController" bundle:nil];
switch (indexPath.row) {
case 1: {
searchTable.editedFieldName = @"Make";
//Pass code number over to DBAccess class
;
} break;
case 2: {
searchTable.editedFieldName = @"Mod";
} break;
case 3: {
searchTable.editedFieldName = @"Method";
} break;
}
;
;
}
</code></pre>
<p>这就是我遇到的错误。</p>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>setPassCode 似乎是一个类实例方法而不是静态方法，但您试图将其作为静态方法访问，您必须像这样声明您的方法才能使其成为静态方法</p>
<pre><code>+(void)setPassCode....
</code></pre>
<p>您的程序崩溃是因为您在类本身而不是类的实例上调用该方法..
希望这会有所帮助</p></p>
